A Busy Summer with a QGIS Conference in Denmark and FOSS4G in Boston

This summer Kurt Menke first attended the 3rd Annual QGIS User Conference, Hackfest and Developer meeting in Denmark. From there he traveled to Boston to attend the Free and Open Source for Geospatial (FOSS4G) International Conference.

He shared many of the new sophisticated and powerful data styling tools now found in QGIS including: 2.5D, 3D, Live Layer Effects, Inverted Polygon Shapeburst Fills, Blending Modes, and some plugins such as Time Manager. Perhaps this could be a workshop shared with CHM partners at a future date? Some examples are shown below:

In Boston Kurt presented the Community Health Maps project. The talk was well attended and there was a lot of interest. Fulcrum was a sponsor of the conference, and Kurt was able to meet with several of the Fulcrum representatives. While there he learned about Fulcrum Community. This is a new initiative designed to help humanitarian agencies, non-profits, NGOs, or Government entities. To begin you need to request a Fulcrum Community account. One important caveat is that data collected via a Fulcrum Community account is anonymized, free, and open to all by default. It is essentially an initiative that will help in larger crowd sourcing efforts. More details will be forthcoming as Kurt explores this and how it may apply to Community Health Mappers.

This month (September), Community Health Maps will be travelling to the University of Connecticut (Community Medicine and Health Care) and to Miami to teach workshops. The workshop at the University of Connecticut will be to a large diverse audience. The Miami workshops will be focused on showing community members how to map damage and issues related to King Tides.

Stay tuned for blog posts on: 1) the future of QGIS, 2) Fulcrum Community, 3) experiences in Connecticut and 4) Miami.

CHM Lab Exercises Updated!

One of the most valuable resources for Community Health Mappers remains the series of lab exercises created two years ago. Our workshops, while effective, are short and only scratch the surface of what you can do with mapping tools. They are basically a quick start guide to Community Health Mapping. The labs however, can be used as a resource to help you build your skills once you’ve taken the first steps towards mapping your community.

The technology changes rapidly. QGIS produces a new stable version every 4 months. Annually QGIS also produces a long-term release. Carto and Fulcrum also update their tools on a regular basis. This mean the lab exercises need to be updated to keep pace.

The good news is that this spring the labs were all updated and expanded. There is some foundational knowledge needed to really take the next step after a workshop. The current revised set of labs includes Lab 0: A Community Health Map Introduction and Reference. This lab has background on the Community Health Maps project and the workflow. It also contains a Glossary of GIS terms, and several appendices covering: A) available software, B) data sources and C) everything you need to know to better understand coordinate systems and projection.

The remaining labs are as follows:

Lab 1 covers field data collection and has been updated to work with Fulcrum. This has allowed us to unify the exercise into one document for both iOS and Android users.

Lab 2 shows you how to bring your field data into QGIS. This includes a tour of the QGIS interface, and how to map coordinate data stored in a spreadsheet.

Lab 3 is named Combining Field Data with other Organizational Data. It shows you how to work with coordinate systems in QGIS. It also covers how to join tabular data to the attribute table of a GIS layer. This is a step that often has to be done to merge socioeconomic data from the U.S. Census to census geography such as tracts or block groups. It concludes with a lesson on address geocoding. This is the process you use to produce points from addresses.

Lab 4 shows you how to do some basic spatial analysis. You learn how to clip data to your study area, measure proximity, query your data to select features and calculate areas/ density.

In Lab 5 you learn how to use some of the great data visualization techniques found in only in QGIS. The lab then walks you through how to compose a map. Along the way you learn some data styling tricks and how to use the Print Composer.

The series concludes with Lab 6 Data Visualization with Carto. Carto underwent a major update and rebranding since the first edition of these labs were created. You can use this exercise to see how to work with the new Carto Builder interface and tools to create an online map of your results. It covers uploading your data, styling and sharing your map with others.

The four labs that deal with QGIS have been updated to include some exciting new features that have been added to QGIS in the last year. Links to the lab data are included. So head to the Resources page and build your Community Health Mapping skills!

GIS as an Educational Tool at MUSC

Submitted by Jennifer Rewolinski

Dr. Deborah Williamson is an Associate Professor in the College of Nursing at the Medical University of South Carolina (MUSC), Charleston. Dr. Williamson, Community Health Maps (CHM) and MUSC have partnered in providing training that integrates GIS and CHM tools for a high school Teen Health Leadership Program. Dr. Williamson has worked with both community members and students.

Dr. Williamson believes that, “GIS has the potential to substantially increase community engagement and is truly a concept of the neighborhood taking control of their data.” She notes that while researchers might study a community, that a community’s input is essential to understanding the cultural and environmental context surrounding health issues: “GIS mapping puts the community members on more of a level playing field with their research partners.” GIS can empower and educate community members to identify their key issues, to become a part of an analysis, and to provide solutions. When communities are given the opportunity to map their own health, discovery, and awareness, positive changes can result.  When a community feels it has more of a say through engagement with GIS, or communication with a map, intervention is more likely to be effective.

For the past three semesters, Dr. Williamson has used GIS in her own classroom as a capstone project for population health students.  They, “find it fun and can take it with them into other settings, it fits into the world of new technology, and it takes people to the next step of looking at health issues.” Mapping offers a different way to help students visualize Social Determinants of Health and to make the connection between what population health is, and the factors that promote or deter it.

Finally, Dr. Williamson sees GIS as bi-directional: it supports visualizing gaps and assets while also providing the ability to disseminate and build on information via intervention programs to improve health outcomes and strengthen communities. GIS is also broadly applicable to almost any discipline and easily used by those with little expertise. “Presenting raw data to a community or students doesn’t mean a lot,” Dr. Williamson comments, “but when that same data is aggregated visually it instantly communicates a message to any audience.” GIS is clearly suitable as an effective educational tool in the classroom and in communities.

CHM thanks Dr. Williamson for her continued collaboration and time spent advancing the CHM program through use of the CHM tools at MUSC. CHM values our partnership with MUSC and hope that the future is as mutually beneficial as the past few years.

Field data collection for the CHM workflow bridges the divide between learning in a classroom and experiencing conditions in a community. For the capstone project, students use CHM labs and parts of the CHM workflow, including phone data collection with iForm or Fulcrum, integration of the data into QGIS, and presenting the data with Carto or Google Maps. Dr. Williamson’s students often upload their data from iForm to Google Maps because of its familiarity and easy access.

One student project involved identifying migrant camps as a community in need, and assessing the community through surveys and key informant interviews.  When the data showed that migrant workers often lack knowledge of health information and access to healthcare services, students mapped locations of migrant camps near Charleston, SC in relation to urgent care facilities and shared the data with the migrant outreach workers from a local community health center. Later, an intervention was developed to provide hands on CPR and first aid instruction to 60 workers. This project displays successful application of CHM tools in an educational and community context resulting in an intervention that may offer real change.
