Hello, I used old spatial allocator `srgcreate.exe`. But I met some problem. Because my vector data is too large (\>2 GB), I cannot export my vector data to esri shapefile. I was able to export my vector data to geopackage (.gpkg). But when I run the script > setenv WEIGHT\_FILE\_NAME $DATA/shapefiles/SouthKorea2018/320.gpkg > or > setenv WEIGHT\_FILE\_NAME $DATA/shapefiles/SouthKorea2018/320 an error message is occured: > ERROR in /work/gwangjin/local/Spatial-Allocator/bin/64bits/srgcreate.exe: Unable to open shape file:/work/gwangjin/local/Spatial-Allocator/data/shapefiles/SouthKorea2018/320.gpkg (WEIGHT\_FILE\_NAME). Exiting… Should I use recent pg\_srgtools? ---

The older Spatial Allocator surrogate creation tools have some trouble with larger data and I don’t believe they support the geopackage format. You can try the newer SurrogateToolsDB which handle larger datasets better. Since your weight file is larger than 2 GB and can’t be stored in a Shapefile, you might research how to load the data into PostGIS. But once it is in there, I think the newer surrogate tools should work. If not, please write again.
