One more general question - in case some of the other users come across some some helpful packages and webpages giving some advice for geoprocessing code-examples in JULIA, it would be great if you could share them here.
I am currently getting acquainted with the ArchGDAL package which provides most of the basic GDAL functionalities in a quite comfortable wrapper.
However, I am still searching for many base-funtions like for example extracting raster values located within a Polygon etc. (in R this would be the extract()-function of the raster package)
I will for now probably simply switch to R for these steps, but in case there are solutions for JULIA available, it would of course be nice to implement everything in one environment.
