New Year Will Bring Updated Labs Including Lab Zero!

It has been 2 years since the Community Health Maps (CHM) lab exercises were first produced. Software changes quickly, and over the last two years the tools involved in the CHM workflow have undergone many changes. For example, this fall the pricing scheme for iForm changed. Though it is still a good product, this price increase puts it out of the category of low cost software. The companion site no longer exists, making ODK Collect more difficult to work with. Fortunately Fulcrum is a fantastic alternative to those two data collection apps. QGIS has released 5 new versions and is now at version 2.18! CartoDb has been rebranded as Carto and has a new interface.

All these changes means it is time for all the lab exercises to be updated. Lab 1 will now be a single lab for both iOS and Android users with Fulcrum. Labs 2-5 will be updated to QGIS 2.18. Lab 6 will be updated to Carto’s new interface. The set of companion videos will also be redone and updated.

Many have worked through these labs and some provided feedback. This information is being used to improve the labs as they are updated. One new item will be Lab Zero. While the CHM workflow is intuitive, it has been suggested that more background information could be useful. Lab Zero will be a companion reference document to the CHM labs. It will contain: A) information on the background of the CHM project, B) software installation instructions , C) a glossary of terms, D) more thorough descriptions of some technical topics like coordinate reference systems, E) a description of how to interact with the QGIS community to get additional help, and F) a list of data resources. This work is in progress and will be ready this spring. Stay tuned!
