Soil thickness layer(s)

Title

Pelletier 2016 Soil Thickness

Description

This is a geotiff from a collection of 6. The full dataset description can be found here . This ingestion is only for the 6th layer called average_soil_and_sedimentary-deposit_thickness.tif. This layer contains "a grid that averages soil and sedimentary deposit thicknesses in meters for users who want a single thickness value that averages across upland hillslopes and valley bottoms." It was made by combining estimates of upland hillslope regolith and soil thicknesses with valley bottom/lowland deposit thicknesses.

Thank you for your request! Maintainers can take the following steps to accept it:

• [x] upload to GEE with rabpro.utils.upload_gee_tif_asset (no spaces or extra periods are allowed in tif file pathing)
• [x] add an entry to Data/user_gee_datasets.json
• [x] test with rabpro.subbasin_stats.main

@jsta While I presently only need the 6th layer specified above, this would make a good test case for ingestion of multiple images into the same imageCollection.

Data had to be converted to int8 to accommodate -1 as a nodata type (I have no idea how -1 was nodata in their original Byte stoarge scheme). Have not tested as 5/6 of the datasets are currently being ingested by GEE.

Test successful! There's some weirdness in the exported id names (many 0s appended):
