Code List for DEM and IPCC data

Dear May Ann,

Thanks for your question, let me explain.

The Grid Generator ( LINK ) extracts the IPCC-ready data from rasters (numeric data). Same thing for the elevation, aspect and slope which come from the Google Earth Engine DEM algorithm using the SRTM data.

If you look in the default Land Use survey used in Collect Earth you will find the code lists used and the meaning of these codes.

In general, if you want to understand the codes used in a survey you should import the .cep file in the Open Foris Collect survey designer and inspect the survey structure there.

Otherwise, you could also open the .cep file with WinZip/WinRAR (at the end the cep is just a zipped folder) and then open the file called placemark.idm.xml

To complete the answer, here are some (older) videos on :

• Installing Collect (the software that allows you to design the survey, not Collect Earth ) : https://www.youtube.com/watch?v=z7TnZnWzZ2w
• Importing a Collect Earth survey in Collect and edit it : https://www.youtube.com/watch?v=Ml76no4XAdk
