For the second edition, I was able to work in color, but the second edition format is slightly smaller, so even the maps that were carried over with minimal changes (other than switching to color) had to be modified to fit the new dimensions and aspect ratio.</p><p>The final result turned out beautifully in my opinion. The book is well written and full of great photos and stories. My family has used it to select several hikes and it adds a nice layer of meaning and context to an already enjoyable activity.</p><p></p><div class="separator" style="clear: both; text-align: center;"><br /></div><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto;

One of the many excellent organizations I get to work with is the <a href="https://www.sightline.org/" target="_blank">Sightline Institute</a>, based here in Seattle. They are a think tank focused on urban sustainability, social justice, and environmental health.<br />
<br />
They ask interesting questions, and every once in awhile, they will ask me to help them answer these questions with maps. In June, I was asked by Alan Durning to make a geographic comparison between three Northwest cities and three European cities: Seattle and Paris, Vancouver and Barcelona, and Portland and Vienna. His article, "<a href="https://www.sightline.org/2019/08/12/what-would-our-cities-look-like-if-we-took-our-climate-change-values-seriously/" target="_blank">What Would Our Cities Look Like if We Took Our Climate Change Values Seriously?</a>" is thought provoking and makes some good points about the disconnect between the way we in Seattle talk about fighting climate change and the land use and transportation policies we actually put in place.<br />
<br />
Making these comparisons was fun, but finding the data for five different countries was not always straightforward. I obtained data from a <a href="https://www.data.gv.at/katalog/dataset/76c2e577-268f-4a93-bccd-7d5b43b14efd" target="_blank">number </a>of <a href="https://opendata.paris.fr/explore/?q=geographique&sort=modified" target="_blank">government </a><a href="https://www.wien.gv.at/viennagis/" target="_blank">sites</a>, but the excellent <a href="https://haoliangyu.github.io/boundary.now/" target="_blank">Boundary.Now</a> and <a href="https://www.openstreetmap.org/export#map=5/51.500/-0.100" target="_blank">OSMexport</a> tools ultimately proved to be the most useful.<br />
<br />
The maps themselves were very simple to make once I had the data--each required three layers: the city boundary, waterbodies/rivers, and parks. Since we are comparing the size of these cities, I used the Europe Albers Equal Area Conic projection for the European cities, and the North America Albers Equal Area Conic projection for the US/Canadian cities. The city pairs are displayed at the same scales:<br />
<br />
Portland, OR , and Vienna, Austria: 1:220,000<br />
<br />
Seattle, WA, and Paris, France: 1:210,000<br />
<br />
Vancouver, BC, - Barcelona: 1:125,000<br />
<br />
I generated a set of simple maps for each city, shown with its companion below (click to embiggen):<br />

I sent these files in Adobe Illustrator to the talented <a href="https://devin-porter.squarespace.com/" target="_blank">Devin Porter</a>, and he worked some graphic design magic to remove smaller parks, rotate Seattle from the original projection so north is oriented up, and produce side-by-side comparisons with labels and stats:<br />

My favorite comparison is between Seattle/Paris, not only because I live in Seattle, but also because there is such a stark difference between the number of people in each place.<br />
<br />
Which comparison made the biggest impression on you? <br />

The Mount Tahoma Trails System Map<div dir="ltr" style="text-align: left;" trbidi="on">
Yesterday I received my 'cartographer's copy' of the <a href="https://skimtta.org/" target="_blank">Mount Tahoma Trails Association</a> Trails System Map. I worked closely with Dave Stonington from MTTA to ensure the map was accurate and easy to use. Dave and his colleagues at MTTA had 2,000 copies of this map printed at <a href="http://www.printcoinc.com/" target="_blank">Printco </a>in Auburn, Washington (the same outfit that prints all of the maps I've worked on for <a href="http://contours-coregis.blogspot.com/2015/06/new-stp-map-for-cascade-bicycle-club.html" target="_blank">Cascade Bicycle Club</a>).<br />
<br />
We worked through seven drafts of this map to ensure we got all of the details right. My favorite part was designing the 'info side' on the reverse of the map. Dave was very open minded and let me take a non-linear approach to presenting a whole lot of information.<br />

Late last year I was asked by Conservation Northwest to produce a map highlighting their work to preserve sagebrush ecosystems in north-central Washington and southern British Columbia, an effort they call the <a href="https://www.conservationnw.org/our-work/habitat/sagelands/" target="_blank">Sagelands Heritage Program</a>.<br />
<br />
I worked with Jay Kehne at CNW to consolidate a variety of marked up paper maps to produce a large format (34" x 44") poster showing their area of interest, movement corridors, protected lands, and other features. The map also needed to illustrate which animals inhabit shrub-steppe habitats, so we used silhouette icons and photographs to provide a more complete understanding of the landscape.<br />
<br />
This map was a lot of fun to create, and last week it won Best Cartographic Design at the <a href="https://www.waurisa.org/Washington-GIS-Conference" target="_blank">WAURISA Washington GIS Conference</a>! <br />
<br />
Below is a low resolution JPG of the map (a full resolution PDF of the map is available <a href="https://drive.google.com/file/d/1Fl01vwC32A4TFYB0kpt1mvQFJsw2mpJn/view?usp=sharing" target="_blank">here</a>).<br />

<br />
The basemap was created in ArcMap, and exported to TIFF. In Photoshop, I created a copy of the map within the study area only and placed it above the basemap. I added a drop shadow to the study area with these settings:<br />

<br />
The animal icons were created in Illustrator, in some cases using Image Trace. Movement arrows were created in Illustrator by drawing lines with start/end 45 degree arrows and a very heavy stroke, then converting the path to outlines so the map would be visible under the arrows:<br />

<br />
The Photoshop map was placed in InDesign, the animal and arrow Illustrator files were layered on top of the PSD, and text, photos, logos, a QR code, and other map elements were placed on the map. </div>

Raise Your Hand Texas is a non-profit educational advocacy group based in Austin, Texas. We worked with RYHT to produce an interactive web map showing the potential changes to school funding under District Partnership Agreements,which enable a school district to be funded similarly to a charter school. This could result in substantially more money for schools, up to $2,300 per student.<br />
<br />
We built this map using a custom <a href="https://www.mapbox.com/" target="_blank">Mapbox</a> style and the <a href="https://www.mapbox.com/mapbox-gl-js/api/" target="_blank">Mapbox GL JS API</a>. The map features a zoom-to-district functionality (in the fly-out on the left hand side), information about each district will appear in a pop-up when a district is clicked, and zooming into the map will reveal individual campuses. Hovering over the campus location will reveal the name of the school.<br />

In 2015 we worked with The Wilderness Society on their <a href="https://www.methowheadwaters.org/" target="_blank">Methow Headwaters</a> campaign, focused on preventing industrial scale mining throughout the Methow Valley of north central Washington. The immediate threat and the impetus for the campaign was a proposed open-pit copper mine on Flagg Mountain that would have had significant ecological impacts on the Methow Valley.<br />
<br />
We produced a series of maps, including some oblique three-dimensional views, to convey a sense of the location of the proposed mine, as well as a proposed withdrawal map.<br />
<br />
As a result of the Headwaters campaign there is currently a two-year mining ban in place, and the US Forest Service has recommended a twenty year withdrawal to the Bureau of Land Management. Please consider supporting this withdrawal and the long-term protection of the Methow Valley <a href="https://www.methowheadwaters.org/take-action/send-an-individual-letter/" target="_blank">here</a>. The deadline for comments is Tuesday, November 13th!<br />

The <a href="https://www.issaquahalps.org/" target="_blank">Issaquah Alps Trails Club</a> has been working to preserve open space and access to trails in the Issaquah Alps region for decades. To mark their 40th anniversary, they commissioned me to create a map showing their accomplishments. By advocating for open space protections and working with a wide range of conservation partners, the IATC has been instrumental in the creation of beloved and iconic protected lands such as Cougar Mountain Regional Wildland Park, West Tiger Natural Resources Conservation Area, Tiger Mountain State Forest, and many others. Congratulations to the IATC!

The City of Seattle has grown tremendously over the past thirty years, and has added 114,000 residents just since 2010 (an increase of nearly 20%). This rapid population growth has resulted in a corresponding rapid increase in the cost of housing and the proliferation of construction projects to try to meet the demand. However, as a result of Seattle's zoning policies and Urban Villages strategy, this population growth (and the resulting changes to neighborhoods) has not been evenly distributed throughout the City.<br />
<br />
We were asked by <a href="https://www.castarchitecture.com/" target="_blank">CAST </a>Architects to model population density within the City of Seattle at three different time periods to get a better handle on where these changes are occurring. We mapped population density at the block level using US Census data for 1990 and 2010 and projected population in 2035 (taken from the City's Housing Affordability and Livability Mandatory Housing Affordability <a href="http://www.seattle.gov/hala/about/mandatory-housing-affordability-(mha)/mha-citywide-eis" target="_blank">DEIS</a> Alt 1). <br />
<br />
Block groups are colored by density and displayed in three oblique views with the observer positioned southwest of the city, looking north/northeast. The maps show that the vast majority of the City's population growth has occurred in just a handful of neighborhoods--just 7% of the City's land area has absorbed 77% of all the growth!<br />
<br />
Matt Hutchins at CAST continues to be a tireless advocate for increasing the
construction of Detached Accessory Dwelling Units throughout the City,
and used these maps in his presentation to <a href="https://yimby.town/" target="_blank">YimbyTown</a> to make the case
that Seattle should expand housing options throughout the entire City, not just
in the designated Urban Villages. <br />

One of my wife's colleagues lives on Whidbey Island. She loves taking visitors on trips around the island, and as a map aficionado, had long dreamed of having a custom map on her dining room table so she and her guests could look at the map before heading out to explore. When she learned that I make maps, we had a discussion about what she had in mind, and then she hired me to make a giant map! This was a real treat for me, since the vast majority of the maps I make are digital.<br />

Even brand new multi-family homes, those built within the last 18 months, cost an average of $45,000 less than older single-family homes, those built prior to 2016.</span></blockquote>

For my third trip to Africa for the McKnight Foundation, I accompanied my friend and colleague Karsten Vennemann. Karsten was funded by the McKnight Foundation to provide GIS support to the Collaborative Crop Research Project (CCRP) for three years, and he hired me to assist.<br />
<br />
The workshop was held at the African Institute for Capacity Development (AICAD) on the campus of the Jomo Kenyatta University of Agriculture and Technology. The institute covers all the bases--meeting rooms, lodging, and food. <br />

As with my previous visits, we used open source GIS software exclusively, primarily QGIS. Unlike previous visits, this workshop was a full week and focused only on GIS--it was not tacked on to a previously scheduled research methods workshop.<br />
<br />
The attendees came from a variety of government agencies, NGOs, and Universities. We had several students in the workshop as well, and they seemed to show the keenest interest and definitely learned the fastest!<br />

Karsten and I divided the teaching duties roughly equally, and tried to give the students a balance of instruction and hands-on exercises. Unfortunately Karsten got really sick the night before our day long session on R (the open source statistical analysis package). I did my best to improvise a session using other materials, but it was difficult without Karsten! Fortunately he recovered by Friday and was able to cover some of the R material in the morning.<br />
<br />
After teaching all day, I would make a bee line for my room, change out of my formal teaching clothes and into shorts and a t-shirt, grab my camera and binoculars, and head for the fields. JKUAT is located outside of Nairobi, and has extensive agricultural fields and the associated ponds, hedgerows, etc, all of which make excellent bird habitat.<br />
<br />
On these daily 'bird walks' I would always see a variety of birds,
but I would also meet students and locals who were just cutting through
the fields. They all thought I was a bit crazy, but they were very
friendly and several groups of people asked me to take their picture.
I'm not entirely sure why, but I was happy to oblige.<br />

After the workshop Karsten and I headed south from Nairobi to Amboseli National Park for a quick safari before heading back to Seattle. This was my third time to Africa for the McKnight project, and on the previous two trips there was little to no time to see the amazing wildlife and landscapes just outside of the cities hosting the workshops. Since Nairobi is surrounded by incredible national parks and reserves, Karsten and I were determined to at least take a couple of days to visit one of the nearby parks. After doing a bit of research, we were able to find a guide who would pick us up at JKUAT, drive us to Amboseli National Park, and act as our safari guide within the park as well.<br />
<br />
We had a very early departure on the first morning and an uneventful (but long) drive south, nearly to the border with Tanzania. We had a good view of the brand new Chinese-built and Chinese-funded railroad connecting Nairobi and Mobassa. We stayed in a (very posh) tent at the Kibo Safari Camp, just outside the entrance to Amboseli National Park.<br />
<br />

<br />
The scenery and wildlife within and around Amboseli is truly stunning. I've never seen anything like it, and it is hard to describe the feeling of being surrounded by wild elephants, giraffes, hippos, hyenas, lions, antelope, and more bird species than I could possibly identify. So I'll let the pictures tell the story.<br />

CORE GIS is ten years old! On Thursday, October 27 we held a joint celebration of this milestone with our friend and colleague Karsten Vennemann of <a href="http://www.terragis.net/" target="_blank">Terra GIS</a>. We both started our consultancies back in 2006 and have collaborated on and off over the years on a wide variety of projects.<br />
<br />
We were joined by clients, family, friends, and our fellow GIS professionals at the <a href="http://www.thebergschrund.com/" target="_blank">Bergschrund</a> in Ballard, the tasting room for the Northwest Peaks Brewery. It was the perfect size, the beer was tasty, and it provided the perfect setting for reflecting on ten years of mapping, analysis, and collaboration.<br />
<br />
Here's to the next ten years!<br />

I collaborated with researchers from Tanzania, Malawi, and Mozambique, and was part of a team of support staff from the UK, Germany and Tanzania that included statisticians, plant breeders, and entomologists. The week was intense but highly productive, and I will continue working with these researchers and their projects over the next year as they strive to increase crop yields and improve soil health. Plus the workshop was held at a beach resort which was very conducive to brainstorming sessions!</span><br />

A new piece of data and analysis we were able to offer to participants at this Workshop is <a href="https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0ahUKEwjpqM-GtOjOAhVB3GMKHdgvBFIQFgghMAA&url=http%3A%2F%2Fdrought.unl.edu%2Fportals%2F0%2Fdocs%2Fspi-program-alternative-method.pdf&usg=AFQjCNHcfKdlEfYTo9LBu3ljKTHfeTpOUQ" target="_blank">Standard Precipitation Index</a> data which we derived from <a href="http://chg.geog.ucsb.edu/data/chirps/" target="_blank">CHIRPS </a>data, produced by the <a href="http://chg.geog.ucsb.edu/index.html" target="_blank">Climate Hazards Group</a> at <a href="http://www.ucsb.edu/" target="_blank">UCSB</a>. The CHIRPS dataset is quite remarkable, and although it is not perfect, is extremely useful to the researchers because of its utility in both interpreting their research results and understanding long term trends in precipitation. CHIRPS is a 30+ year quasi-global rainfall dataset that blends data from ground-based observation stations and satellite data. The data has a global spatial resolution of 0.05 x 0.05, and daily data are available for Africa at a resolution of 0.25 x 0.25 degrees. Data can be downloaded in daily, pentad, dekad, monthly, 2-monthly, 3-monthly, and annual time steps.<br />
<br />
I used it both for the Cowpea Systems project in Mozambique and for the Best Bets project in Malawi. The Cowpea Systems researchers wanted to see patterns of precipitation relative to their study areas for the two dekads that bracket the end of March/beginning of April. The SPI clearly shows the very dry conditions in the southern part of the country, where many farms failed. The Best Bets project requested both monthly average precipitation and monthly SPI for all months in last year's growing season.<br />
<br />
In both cases, the SPI maps express precipitation over a given period in terms of standard deviations from the 35 year average for the same time period.<br />

Over the last few years I have produced several high-resolution land cover classifications using the excellent 1-meter resolution 4-band NAIP orthophotography available from the <a href="http://www.fsa.usda.gov/programs-and-services/aerial-photography/index" target="_blank">USDA APFO</a>.<br />
<br />
For the most recent classification I used the 2015 4-band NAIP to produce a landcover classification of the Hylebos Watershed for <a href="http://www.earthcorps.org/" target="_blank">EarthCorps</a>, who have been actively restoring riparian areas and wetlands in the watershed. They are planning to use the landcover for a variety of analytical and prioritization purposes. Unfortunately, the sun angle at the time of image acquisition produced a lot of shadowed areas, which reduces the usefulness of the landcover data.<br />

In order to fix this, I tried a new approach: extract the shadow class, mask each of the bands to the shadows, and run an unsupervised classification using isocluster (the original landcover classification was produced using supervised classification on six bands, to learn more please see <a href="https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0ahUKEwiGuNeO96fNAhUM1WMKHdg2CkcQFgggMAA&url=http%3A%2F%2Fwww.waurisa.org%2Fconferences%2F2012%2Fpresentations%2F11%2520Chris%2520Behee%2520Vegetation%2520Modeling%2520with%2520NAIP%2520Color%2520IR%2520Imagery.pdf&usg=AFQjCNHJYzhQ7qCJhtwAAIH4oHYn_hwwIw&sig2=sotzoo0Zzxbm5tWywddFZg" target="_blank">this </a>excellent slide deck produced by Chris Behee).

The isocluster output generated a new set of 10 classes, three of which represented forested classes.<br />

My hope was the remaining 7 classes could be used to differentiate dry grass and impervious surfaces, but the extremely dry conditions during the 2015 summer resulted in very low photosynthetic activity and consequently the remaining 7 classes were highly confused, so they remained as shadows.<br />
<br />
The resultant forested classes within shadows were added back into the classification to produce the final product:<br />

Yesterday I attended the <a href="http://www.waurisa.org/conferences/2016_Conference_Index.php" target="_blank">2016 Washington URISA</a> conference in Tacoma and gave a presentation called <a href="http://ballardhistory.org/ballard-overview/" target="_blank">Mapping Historic Ballard with Crowd Sourced Mobile Data Collection</a> to a room full of my GIS colleagues. The slides from my talk are available <a href="http://coregis.net/assets/PDF/CORE_GIS_MHB_WAURISA_v2.pdf" target="_blank">here</a> and should also be available on the conference site sometime soon. I had a great time at the conference, and as usual came away with new friends, ideas and insights. <br />
<br />
The Mapping Historic Ballard project is nearly complete and we will be celebrating the completion of the project on Saturday, June 4 at the Sunset Hill Community Center (more details <a href="https://www.facebook.com/events/1599246947052100/" target="_blank">here</a>).<br />

Last year I had the pleasure of working with local author Steve Olson on his new book <a href="http://books.wwnorton.com/books/Eruption/" target="_blank">Eruption: The Untold Story of Mount St. Helens</a>, to be published next month by W.W. Norton. I made several maps for the book, and the best thing about working with Steve (from a cartographer's perspective!) is his love of maps and willingness to take a somewhat unorthodox approach to integrating maps into his book. We were able to develop several 3D views that I think worked really well (examples below).<br />
<br />
Steve will be talking about the book with Steve Scher at Town Hall on Monday, March 7, and you can get tickets for that event <a href="https://townhallseattle.org/event/steve-olson-with-steve-scher/" target="_blank">here</a>. For those of you in Portland, he will be speaking at Powell's Books on Wednesday March 9 at 7:30. More info <a href="https://shar.es/14BBvR" target="_blank">here</a>. <br />
<br />
You can pre-order a copy of the book <a href="http://www.elliottbaybook.com/book/9780393242799" target="_blank">here</a>, <a href="http://www.powells.com/book/eruption-9780393242799" target="_blank">here</a>, and of course <a href="http://www.amazon.com/Eruption-Untold-Story-Mount-Helens/dp/039324279X/ref=mt_hardcover?_encoding=UTF8&me=" target="_blank">here</a>. <br />

The <a href="https://www.sightline.org/" target="_blank">Sightline Institute </a>approached me with a series of interesting analytical questions--who pays for Seattle's elections? Where do they live? What are their sociodemographic characteristics?<br />
<br />
Using data from the 2013 City elections Sightline obtained from the Seattle Elections Commission, the King County Assessor, and the US Census Bureau, I was able to map the precise addresses of contributors and determine characteristics about their housing, income, and race.<br />
<br />
Using this information, the analysts at Sightline were able to describe the majority of contributors as rich, white people who live in view homes or near water. This information is being used by Sightline to promote for the Honest Elections Seattle Initiative which would (among other things) distribute $100 of Democracy Vouchers to each registered voter in the city.<br />
<br />
Below are some maps from the analysis, just click to embiggen.You can download the entire study <a href="http://www.sightline.org/download/49965/" target="_blank">here </a>(PDF link).<br />
