Student GIS Projects

I’ve been teaching the Introduction to Geographic Information Systems (GIS) class in the Earth, Environmental, and Sustainability Sciences (EESS) Department for about 11 years. Suresh Muthukrishnan (department chair) also teaches the course. I’ve learned a ton from him. Here are some things I really enjoy about teaching the course:

House flipping hotspots near the Cincinnati Streetcar route. An example map from student Charlotte Moore.
  • Interdisciplinary Nature – Students from across campus take the course. Of course, there are lots of EESS majors. However, even those projects run the gamut. Projects like geologic mapping, landslide risk, sustainable farming, and even mapping data from GPS collars on mountain lions. But students of history, economics, sociology, computer science, business, and music also come up with some great projects.
  • The Opportunity to Learn – Every semester, students will come up with novel questions and methods. I think my typical response is, “I haven’t done that before, but I know it’s possible. Let’s figure it out together.” So I learn something new about GIS, as well as all the topics above, each time I teach.
  • Community Connections – Many of the projects involve community partners–folks like the Greer Police Department, Upstate Warrior Solution (which serves veterans), Greenlink (our public transportation department), local land conservation non-profits, the forestry department, and community associations. Our first deep partnership involved mapping streetlights, which I’ll talk about in another post.
  • Working with Our Post-Baccalaureate Fellows (postbacs) – I’m grateful to get to work with two recent Furman graduates who are on our team. Catherine Lippert (Sustainability Science) and Sam Hayes (History and Politics and International Affairs) are an integral part of teaching the course. They have serious GIS chops and roll up their sleeves to help the students with projects, every step of the way.
  • Project-Based Learning – The course involves a semester-long project. It’s a real challenge to teach GIS principles, create meaningful labs, AND support students as they use these concepts and tools to apply what they’ve learned to address a real-world problem. Every semester I think, “We took on too much. This isn’t going to happen.” But it always comes together. Here’s the syllabus for the class.
An historic, georeferenced map of Charleston Harbor (1711). From a student project by Kylie Gambrill.

Here are some examples from a recent class. I don’t want to make it seem like I’m taking credit for these. The students did the work. Catherine, Sam, and I were teammates. However, the examples are illustrative of the range of projects that are possible. The projects are easier to share, now that we have switched the delivery format from poster presentations to StoryMaps.

Charlotte Moore: Transit-Motivated Gentrification: An analysis of gentrification in Over-the-Rhine, especially as a result of the Cincinnati Streetcar.

Caroline Vickery: Contextualizing Upstate Farms: A preliminary examination of land use and nutrient loading for small farms in the Upstate of South Carolina.

Kylie Gambrill: Understanding Change: The Charleston Harbor — Our perceptions of the environment around us depend upon the cultural context we find ourselves in.

Bennett Dean: Affordable housing and public transportation in Greenville.

 Chloe Sandifer-Stech: Recommendations for green space around Enoree Career Center: A study of the influence of tree density on carbon storage.

Jake Gerardi: Land Sparing/Sharing Impacts on Birds: Assessing habitat quality of southern bird species using ecological principles in Greenville watersheds.

Madison Eichhorn: Affordable Housing & Good Jobs – An evaluation of proximity, density, and availability of affordable housing and employment.

Austyn Feigenbaum: Boating Safety Zones and Florida Manatees: An investigation on the relationship between manatee death rates and boating safety zones along the coast of Florida.

I hope you’ve enjoyed seeing the range of student projects and learning more. It’s a pleasure to see all the hard work result in such great studies and stories.

GIS and Social Justice

At a recent faculty gathering on community engagement, I was asked to provide some examples of how Geographic Information Systems (GIS) is being used to support different social justice initiatives. While there are many examples, I didn’t have much time to share, so I highlighted just a few compelling examples, which are shown below.

If you’re interested in learning more about GIS and social justice, these resources are a great place to start, although I find the inequity that the maps reveal to be very disheartening.

New Orleans
New Orleans, LA from Business Insider – http://www.businessinsider.com/most-segregated-cities-census-maps-2013-4?op=1

  1. The Revolution Will Be Mapped – This article gives an overview and describes some recent cases in which maps played a key role in highlighting discriminatory practices in the provision of public services.
  2. Redlining Maps –If you click on an area, especially those in red, you can see the disturbing (stunning, actually) area descriptions–circa 1930.
  3. Million Dollar Blocks – NPR highlighted the Justice Mapping Center’s work on visually representing incarceration rates and costs. Million dollar blocks are “areas where more than $1 million is being spent annually to incarcerate the residents of a single census block.” The maps are being used to identify areas for establishment of re-entry programs. You can check out data for Greenville County by zip code and census block here. Click on the state, then the county for details.
  4. Maps of Highly Segregated Cities – Each map provides a dissimilarity index. “A score above 60 on the dissimilarity index is considered very high segregation.” The symbology is very powerful. For New Orleans, you can clearly see the high elevation area along the river that geographer Richard Campanella refers to as the “white teapot.”
  5. Underbounding – I happened upon this term while doing a little research for the session. This is a practice by which certain groups (usually poor minorities) are excluded from annexation and associated services.
  6. Dividing Lines: School Districts in the US – This map shows how current educational funding practices limit fair access.
  7. Social Explorer – Our library is currently evaluating a subscription to Social Explorer, which should make it much easier to use the browser to map demographic data going all the way back to the 1790 Census. No desktop software required.

Elevation Profle and Google Earth

I took a field trip with a colleague who is headed to Guatemala in a couple of days in order to test the elevation accuracy of the iPhone, iPad, and Trimble Nomad.  I’ll post the results shortly.  I discovered a feature in Google Earth that I didn’t know existed–the elevation profile.  After adding a track we recorded of our hike back using MotionX HD on the iPad to Google Earth, it was easy to create an interactive elevation profile of the short trip.  The yellow arrows show the point-of-interest on the path and the corresponding location on the elevation profile.  Pretty cool!

 

Visualizing the World – Wow!

This is a really powerful tool for viewing global statistics that might be useful for class.  The visualizations in Hans Rosling’s presentation  are pretty amazing.

Motion Map

The tool Rosling uses in the presentation is available online (along with his blog).  It took me a little while to figure it out how to use it, but experimentation with the maps and charts, along with the video tutorial, really helped me realize how much is here.

Indicators include health, economic, education, environmental, and more data from the UN.

The site also provides information about how you can use Google Spreadsheets to make your own motion charts.  I experimented, and the process is fairly straight-forward for charts but doesn’t include the mapping piece, which is available for the UN data on Rosling’s site.

Geospatial Revolution Project

Now that spring semester is over, I’m hoping to pick up my blogging pace again. Penn State University announced the geospatial revolution project recently, which involves the creation of video episodes to explain the importance and role of geospatial technologies in our world. Check out the trailer below. This looks intriguing!

Whenever I try to articulate my excitement about the power of geospatial technologies for learning across the curriculum, I’m usually disappointed in my ability to convey the message. It looks like these episodes might do a much better job of highlighting that connection. I’m currently taking GIS courses through Penn State’s online program, so I recognize at least one of the interviewees in the clip!

 

Campus Technology Award

Our project using Google Earth to connect Boston, NY, and Greenville in Lloyd Benson’s Urban History class won an Annual Campus Technology Award. Check it out!

Here’s a little bit more info on the project that I put together for a NITLE conference this spring.

Project FAQs

It’s amazing how quickly things change. Picasa and Flickr now automatically put geocoded images on the map. For Flickr you have to make sure this is set to ‘yes’ in the privacy and permissions section of your profile.

flickr

Here’s an example of an image in Picasa that is automatically placed on the map. I took it with an iPAQ with built-in GPS. I almost walked right through the web when getting out of my car. That would have been interesting! It reminds me of the time I put my kayak on my head to carry it, and a big spider that had set up camp started falling towards my face. I closed my mouth just in time!

Costa Rica Day 6 and home

See flickr for all the pics from the trip.

Got up early to go with a crew over to Firestone. They were casting nets to catch leaf litter for another study on the property. I caught up with some email and talked to Susannah briefly before heading back for more GIS instruction. I really learned a lot. Warren is a great teacher and very patient with all of us. We turned data we gathered with the clinometers and compasses into latitude and longitude using start and finish anchor points we took with the portable GPS devices and COMPASS software. Then we imported all the data from the surveys we had done to see the additional trail maps. It was way cool! All of the points help GIS interpolate elevation, slope, and aspect information, so we get a better handle on both the Hacienda Baru and Firestone property.

eric mapping

I took a quick walk by myself on the trail to the playa (beach). We ate a quick lunch, packed, and took a different route back to San Jose. This road was paved, but very curvy, with some drops that were pretty impressive. I was happy for dramamine and decided it wasn’t worth watching all the crazy passing we were doing on hair-pin turns.

Carol on steep cliff

We stopped at a little over 8,000 ft on the way up and climbed a peak for some great views (see flickr). On the way back into the bus, we ran into a young guy from Japan who had biked from Calgary Canada!! He was looking for a place to pitch a tent for the night. He seemed to be in great spirits for such a long uphill ride with crazy traffic all around.

Mike and Jose Luis

We went out for dinner in San Jose, which is hopping in the evening. Jose-Luis and I (picture above) crossed a street and got stuck in the middle of the road. No one let us go and just honked and whizzed past. I later asked Eric to teach me how to curse in Spanish. I have a couple of phrases in my back pocket that might serve me well in the future 😉 I’m on the plane home to Atlanta, then I drive back to Greenville. Can’t wait to be home, but it was a great trip!

Costa Rica Day 4 and 5

It’s Thursday night before dinner. Just catching up on the events of the last couple of days. Wednesday we surveyed most of the day – the main trails of Haciendu Baru in the morning, then up the slopes towards the overnight camp during the afternoon. The afternoon trip was especially beautiful, and we met up with the group that had hiked up to the top of the ridge, then back down, to connect the surveys.

sloth

We saw monkeys in both the morning and afternoon. They were especially active during the late afternoon hike back down the ridge. See flickr for snapshots. I didn’t take too many photos since we were so busy. Surveying got easier as we went. The challenge was getting a decent compass reading on some of the steeper slopes. The work was tedious but pretty rewarding when we saw the final survey. Stayed up late talking GIS with Kate, Travis, and Warren.

monkeys

Thursday morning. Not feeling well at all. We had a choice to stay for detailed GIS instruction or survey in the river or up near the overnight camp towards the Firestone property. I volunteered for the latter if they needed bodies, but they had enough, so I stayed put. Probably a wise choice based on how I was feeling, but it sounds like both groups had great and strenuous hikes. As the groups left, they caught site of a baby sloth in a tree near the trail. We went over to snap some pictures. It was really close, so I got some great shots. Man, they don’t even look real and are definitely low energy – like me on Saturday morning.

Rain moved in just as the groups were returning. The group that went up to the overnight camp ran into an fer-de-lance. Pedro, the guide for this section, lightly stepped on the head of this highly venomous snake and pinned it with a forked branch, while the rest of the group snapped some photos. Keith said he’d send the shots, and I’ll post his pics soon. It looks like the snake was hot on the trail of lunch, a garter snake, and his would-be prey was also caught on film.

A little more GIS work in the afternoon. I opted out of gathering GPS data on the nearby trails and volunteered to pick up the group hiking the 5k road back to Baru in the car as the storms rolled in. They were pretty close by the time I caught up with them. Pretty low energy day, but I learned a lot of GIS details.

Haven’t had access to phone or internet since Tuesday, so I hope Susannah and the kids aren’t too worried. But there’s really no way to contact them. Hopefully I can put in a call on Friday to them from the Firestone station.

We take a trip back to San Jose up the steep side tomorrow, then head out Saturday morning for home. It’s been a great trip so far! Can’t wait to see Susannah and the kids though.

Costa Rica Day 3

It’s Weds. morning before 8 am and already incredibly hot and steamy. Today is going to be a scorcher. The power died this morning, so I’ll have to type quickly on battery power. Yesterday morning (Tuesday) we hiked the Firestone reserve property taking the North trail along the boundary of the property. We hiked along the river to the waterfall (see flickr pics) and then up the trail for a steep 1,000 ft ascent to the ridge where we met up with the team geocoding the numerous petroglyphs on the site. I took a few snapshots of the petroglyphs, and I think the running total for this ancient rock art is now over 50 on the 300 acre property. Bamboo was planted back when the property was pasture, and it’s really taking over up top. Right now contractors are cutting and treating the wood on site for use in local sustainable building initiatives to keep growth in check. We climbed the bamboo ‘tree fort’ and looked at several petroglyphs while on the ridge, then caught a ride down the mountain with the contractor.

rest

The station was abuzz with student researchers, one of whom described her research to study the impact of the clearing effort on the thickness of remaining bamboo growth. She cautioned about the many snakes she’d seen that morning and commented, “Geez, I hate snakes”. Lunch was great. I’m getting hooked on fresh mango and pineapple.

After lunch Warren went over some GIS information, and we learned some surveying techniques using compass bearings and inclination measurements. It really takes a steady hand and some patience to get good readings. After that we surveyed a loop on the property and then ran the data through COMPASS software to determine our loop closure error which was less than 2%. Not too shabby! Travis did a great job with measurements.

Back to the property for dinner, a little more GIS instruction, and a great slideshow from Keith and Don (the bat experts) on some visits to caves in Panama. I was going to run on the beach this morning and opted for an extra hour of sleep instead. Determined to try tomorrow am, my last chance, I think.

Today we stay on the Haciendu Baru to survey in the lowlands, so we can connect to the Firestone surveys. That means hot and buggy and no internet, since we only get that at the Firestone station. I’m anxious to gather real rather than practice data. I had a quick Skype conversation with Susannah before the kids got out of school, and it worked pretty well. I miss her and the kids a lot and am bummed that it will be another day before I can communicate with them in any shape or form.

Man, it’s hot today, and it’s not even 9 am. More tomorrow. More pics from Tuesday added to flickr. Check ’em out.

Costa Rica Day 2

We’re now at the Hacienda Baru, after a long, bone-jarring and motion-sickness-inducing ride down the mountain and past palm oil plantations. I posted pictures on my flickr account which includes a shot of one of the oil palm processing plants along the route.

The cabins are nice with loads of fans to take the edge off the damp afternoon heat.

We got in late afternoon but still had time for a quick hike in the property. It’s beautiful. We hiked down to the Pacific ocean as the sun was starting to set and hiked back using flashlights while within the canopy. It was still light enough outside the canopy that we didn’t need artificial light. There were quite a few bats buzzing us on the walk back and apparently this is the trail where they saw a fer-de-lance last year. Nothing this time – phew!. See flickr for photos from the hike.

beach 1

After dinner on the property, we headed back to the cabins. On the way we saw two large frogs. We got so into tracking down the frogs that we failed to realize we were standing on an ant hill (probably the frog’s source of food). Once the biting began, we quickly realized we were covered in ants and started the appropriate swatting and dancing routine until the little buggers were gone. Ouch.

Got up around 5 am and starting composing email and the blog, so that I could make the most of internet time today, if we get it. Off to the Firestone Preserve to check out the property and start GIS training in the afternoon.

Oh, I almost forgot. Check out the crocs we saw at lunch. They’re huge!
