error when running dem2tintiles using example file "dems_10m.dem" #7

when using command: dem2tintiles --method terra --max-error 10 --input "/tin-terrain/3rdparty/craterlake/dems_10m.dem" --output-dir "/tiles" I get the following error: ERROR RasterIO.cpp:324 Can not match projection to EPSG:3857

fester commented 6 years ago

This is because the crater lake DEM is not in EPSG:3857. You need to reproject it using something like this: gdalwarp -t_srs EPSG:3857 dems_10m.dem dems_10m.tif. In order to correct visual artifacts you can specify resampling algorithm with -r argument, please see the official documentation.

I added a section in README about how to use sample datasets. Closing this.
