Hi Sebastiaan, Thank you for putting in the time to test and respond. I am a little confused as to why we are seeing different results between spatialite and proj itself for what should be the same transformation. For example: echo -122.338928 47.629273 | cct -c1,2 -d6 -z0 -t0 +proj=utm

2022-03-29 Thread Brian Miles
Package: libspatialite7 Version: 5.0.1-2 Hello, I have discovered a bug in libspatialite7’s ST_Transform() function where transforms from WGS84 geographic coordinates (EPSG:4326) to NAD83 UTM 10N (26910) returns the result for WGS84 UTM 10N (32610). This appears to only be occurring on
