So I'm using qgis 2.6.0 and I have a csv (converted into a .shp) with two geometry columns, I want to create a new column with the distance between the two geometry:
shot.lat shot.lon haul.lat haul.lon
57.563 -12.986 57.534 -12.985
57.7 -13.304 57.67 -13.299
57.611 -13.529 57.582 -13.538
57.594 -13.294 57.565 -13.315
57.432 -13.314 57.402 -13.304
57.339 -13.053 57.311 -13.072
I am trying to use the function geometry function "distance" with the following expression:
distance( geomFromWKT( 'POINT("shot.lon" "shot.lat")' ) , geomFromWKT('POINT( "haul.lon" "haul.lat")' ))
This should then create a new field with the distance between the points. When it runs though, it just returns Null. Am I missing something obvious?
