Basically I want to perform spatial queries like distance calculations in PostGIS using data from shapefiles with different projections, some of which have no SRID code that I can find and also which ...
I'm having a problem transforming a point from the Australian MGA UTM datum (eg MGA Zone 51 http://spatialreference.org/ref/epsg/28351/) to WGS84 using GeoDjango. I've narrowed that down to a problem ...
Given a projection SRID, is there a way I can obtain the coordinates unit string (meter, degree, ...) ? In PostGIS for example, it looks like it is present in the srtext column of spatial_ref_sys. ...
PostGIS is rejecting an srid code for my projection. I've found a nearly identical projection w/ a legit srid. Will it work?
My projection is this: NAD 1983 StatePlane North Carolina FIPS 3200 Feet, which has a proj4 string that looks like this: +proj=lcc +lat_1=34.33333333333334 +lat_2=36.16666666666666 +lat_0=33.75 ...
For a Precision Agriculture application I need to make calculations in UTM projection. The data will be stored in Postgis and is made of soil samples results (point data) and field boundaries of many ...
So I'm getting some user drawn polygons in WKT with OpenLayers. (Web Mercator CRS) and I now need to now convert it to SRID4326 so can do some spatial queries. However, when it fails to do a ...
