Are you using the sqlite3 command-line shell, or something else?

Hi,
I'm trying to create an SQL in Sqlite3 which returns the X &
Y coords for a point, given origin coordinates in degrees, with distance
and bearing to the new location.
My install of Spatialite (Mint Linux) does not support the Project()
function, and it seems easier to write the SQL
7 matches
