Dear Collect Earth Team,

I have been using the grid generator, and for the grids that have been generated I have opted to generate additional information pertaining to the DEM data (elevation, aspect, slope) and IPCC data (climate, soil, gez). The csv files list out numerical values for each of these variables for every grid (for example, the soil variable has values ranging from 0 to 8). However, I am unable to locate a code list to interpret the numerical codes for their corresponding value. May I please have assistance in this regard?

Thank you, Mary Ann

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
