GeoStats.jl v0.83

We are actively working on an improved interface for geostatistical learning. The Learn transform has been refactored to handle labeled geotables produced with the new label function:

The columns of the geospatial table are now colored according to their role in geostatistical modeling. Predictor variables are colored in sage, target variables are colored in red, and the geometry column is colored in teal.

More updates

  • DropLocalLowHigh is a new transform that drops local extremes with a moving neighborhood. It can be useful to remove data acquisition artifacts in various applications.
  • All EPSG and ESRI codes for UTM coordinates have been mapped to our native CRS types with WGS84 and SIRGAS2000 datum. That should cover a lot of datasets in industry.
