Community Health Maps (CHM) necessarily focuses on low cost and open source tools. This is because our goal is to find mapping tools that can be used by any community group, no matter the budget or resources. However, that doesn’t preclude people from using Esri software or other proprietary mapping tools too.
One benefit of using Fulcrum for data collection, and QGIS for analysis and cartography, is that they both support a wide range of common GIS formats. This means that the data you’ve created via these two platforms can be easily brought into Esri’s ArcGIS software. Similarly if you have data you have created with Esri tools they can be brought into QGIS or Carto. This feature is known as 'interoperability' and QGIS is highly interoperable. For example, QGIS can work with shapefiles, Esri personal and file geodatabases, KML and over 100 other formats!From the outset we knew there were many scenarios for mapping software being used in public health and community organizations. For instance, there are larger organizations who are already using tools such as Esri’s ArcMap, ArcGIS Pro or ArcGIS Online. With this scenario there are still several reasons the CHM mapping tools could be useful.
- It might be that the organization doesn’t have enough Esri licenses for everyone in the office who’s interested in doing mapping work. In this case Fulcrum, QGIS or Carto could be used to fill the need.
- An organization may find that their Esri license doesn’t give them access to certain tools they need. They could use comparable tools in QGIS to fill the need, without having to pay extra license fees just for one or two extra tools.
- There may be smaller affiliated satellite groups that don’t share the same access to the software. In this case, these groups could use CHM suggested tools. Because of good interoperability they would then be able to provide data back to the central hub, where they could be incorporated seamlessly with the rest of the organizations data.
- There may be certain tasks that are easier and faster to do in one piece of software and others that are easier in another. For example, I use both ArcGIS and QGIS daily to do different things. Many beginners also find QGIS to be more intuitive. GIS is simply a tool and by incorporating QGIS you are giving yourself a bigger toolbox.
If you are in an organization using another software package don’t worry. The tools we are promoting as part of this project can be integrated quite seamlessly with your current tools. It doesn’t have to be Coke or Pepsi, or Ford or Chevy. You can have both!
