Mapping Belize

Last month my oldest son's teacher asked me to talk to her class about mapping, and in particular, how elevation above sea level is measured. I happily accepted and prepared a talk showing some of the mapping I've done over the years, and did my best to convey to a group of 5th and 4th graders how elevation is measured.

At the end of the talk, the students asked if I would make a map for them. I promised I would and actually created two--one of the ecosystems of Belize and one showing elevation and topography.

Topography of Belize. Click here for a full-res PDF.

The elevation data is from a mosaic I created using Shuttle Radar Topography Mission data. There were numerous anomalies in the data, most of which I cleaned using focal windows, but it is not perfect. The majority of the base data came from the Biological Diversity in Belize website, including the ecosystems.

It was a fun mapping exercise and a great way to familiarize myself with our new (temporary) home!

CORE GIS Has Temporarily Relocated to Belize

My family and I moved to Ambergris Caye, Belize two weeks ago and we will return to Seattle in June 2014. I've relocated CORE GIS for the duration of our stay, and will continue working with all of our Washington and Oregon-based clients. I've ported the CORE GIS telephone number to Vonage (VoIP), and soon you will be able to call the same number and will not incur any international long distance charges. Email, Skype, and join.me will also be good ways to communicate and collaborate. Unfortunately my Seattle cell phone does not work in Belize, but if you need to get in touch right away you can reach me at +011-501-620-7249.

During daylight saving time, Belize is one hour ahead of Seattle, and during standard time, it is two hours ahead (same as US Central Time). Of course, meeting face-to-face will be a little more difficult, but I'm planning on one, possibly two trips back to Washington to meet with people, and will post those dates here once they are confirmed. Be sure to let me know if you'd like to get together.

And now for some photos of Belize!

Where in the World?

Here is the map I made of the countries of origin for the students I spoke to last Friday.

Guest Lecture at UW

On Friday I gave a talk to my friend Mihaela's class (and her colleague's class) at the University of Washington. She teaches non-native English speakers, and towards the end of the course invites a variety of guest speakers to help her students build their comprehension of academic lectures. I talked about mapping, and gave an overview of the clients I work with, the types of projects I do, and where the data come from. They were attentive listeners and asked some great questions at the end.
These are the fine people who listened so attentively to my talk about maps

After the Q & A I offered to make a map showing all of the countries represented by the two classes in attendance. I'll post that here later this week when it is finished.

Three Meetings, Two States, One Bike (...and a train)

Last week I had three meetings--two in Portland, Oregon, and one in Vancouver, Washington. The first meeting was with the United States Army Corps of Engineers, Portland District, and the Center for Natural Lands Management. The second was a presentation to the Conservation Committee of the Columbia Land Trust (and several CLT board members) about progress to date on the revision of CLT's conservation plan. The third meeting, the next day, was in Vancouver, with Clark County and CLT.

Miraculously, all three meetings were scheduled within 48 hours of each other, and since they took place within ~10 miles of each other, I decided to do the whole thing without the use of a car. On the morning of the first two meetings, I left my house in the Fremont/Ballard neighborhood of Seattle, rode downtown, and caught the 7:30 am train. Amtrak has done a great job adding bicycle racks to their baggage cars in the PNW, and the logistics were really easy. After the train departed King Street Station, I fired up my laptop and used the power outlet and on-board WiFi to get a bunch of work done on the 3 hour trip to Portland. We arrived 1/2 hour early (!) and I was able to grab lunch before my meeting with the USACE.

The USACE Portland District offices

The USACE mission is to:  "Provide vital public engineering services in peace and war to strengthen our Nation's security, energize the economy, and reduce risks from disasters." Their 'vision' is:  "A GREAT engineering force of highly disciplined people working with our partners through disciplined thought and action to deliver innovative and sustainable solutions to the Nation's engineering challenges."

I met with them because I am working for the Center for Natural Lands Management on a continuing study of the habitat of the Streaked Horned Lark. The STHL is an endangered species that nests on islands in the Columbia River. Historically, these islands were replenished by seasonal floods, but since the Columbia River and many of its tributaries have been dammed for hydropower, the Larks' current habitat is created by the USACE depositing dredge spoils on islands within the river channel. The Corps is responsible for maintaining navigable waters throughout the US, and in the Columbia, that means ensuring passage for cargo ships entering the river from the Pacific. Since the Columbia is still a pretty dynamic river, the Corps has to dredge every summer to maintain the channel, and the sand has to go somewhere. Turns out, Larks really like a mix of bare sand and low vegetation. The purpose of our meeting was to figure out how the Corps and all the other main players in the Columbia can work together to maintain navigability and do so in a way that creates and enhances suitable habitat for the Lark. It was a very positive meeting, and the Corps is very interested in collaborating with CNLM to help maintain and recover the Lark.

The presentation I gave to the CLT conservation committee and board was an update on the work we've done thus far to enhance and revise the conservation plan I originally worked on in 2006/2007. The primary objective for this 'conservation plan 2.0' is to help CLT focus on parcel-level priorities. This has actually become much easier over the past several years, as the resolution of data has improved and the variety and applicability of data has increased. For example, in the first round of conservation planning, we had to aggregate predicted species distribution data from the National GAP project to 5th-field watersheds because Washington and Oregon used different methodologies to derive the landcover that forms the underlying basis for the predicted distributions. In the time since the first round was completed, the project was completely re-done (conveniently called 'ReGAP') using the same methodology and data for the entire PNW. This greatly increased the resolution of the data we are using to help the land trust prioritize their conservation activities.
The northern 1/2 of the Long Beach Peninsula in Washington. In the first round of conservation planning, our modeling  with GAP data indicated the peninsula had important habitat. 

In the second round of conservation planing currently underway, we can use the ReGAP data to determine which portions of the peninsula specifically are important for habitat (green areas = best habitat)
In addition to the terrestrial biodiversity prioritization, we are also working on:

  • A parcel-based estuary restoration/conservation prioritization
  • Salmon habitat acquisition/restoration prioritization
  • Climate change resiliency analysis
  • Seal level rise impacts analysis
  • Portland Metro prioritization
  • Threat assessment

The meeting was held at the office of Lane Powell, in a conference room with a great view of the Willamette River

The presentation seemed to go well and we received lots of constructive feedback.

After the conclusion of the CLT presentation, I rode from downtown Portland to downtown Vancouver. The bicycle infrastructure in Portland is amazing--bike lanes (some of them separated) and signage are everywhere. Unfortunately, the I-5 bridge across the Columbia is every bit as sketchy as the Ballard Bridge, but I arrived in downtown Vancouver safely.

The final meeting was with Clark County and CLT at CLT's offices in Vancouver. We are working for Clark County to help them update their conservation areas acquisition plan, which is focused on habitat, forestry, and agriculture. Similarly to the CLT conservation plan, this presentation was an update on progress made to-date. This was also a constructive meeting, and at its conclusion I felt like we are on the right track and will be able to deliver a useful set of priorities to help the County focus its limited resources to conserve important natural resources.

After the meeting wrapped up, I grabbed a burrito on the way to the train station, hopped the train, had a very relaxing ride to Seattle, and made it home in time for bed.
Waiting for the ride home. My bike is at the bottom of the picture.

I will definitely do this again next time the stars align and I have a bunch of meetings down south.

A Quick Map of Farmland Loss in Western Washington

I made this one for the American Farmland Trust. Stats were provided by AFT.

The CORE GIS 2012 Holiday Card

This time, with more reindeer! I used three historic maps to make this card, all from the David Rumsey collection of historic maps. The reindeer bit is from a 1967 Polish atlas, the holly leaves are from a map of forests produced as part of the tenth Census of the USA (1880), and the red holly berries are from a map of North America "Exhibiting the Recent Discoveries, Geographical and Nautical; etc etc" published in London in 1824.

If you did not receive a CORE GIS holiday card and wish to be on the list for next year, drop me a line!
