Hello,
I am creating data for Lesotho for a volunteer project.
I am currently using OSM as a basemap which has a EPSG of 3857. I am creating
new features stored in shapefile.I want to calculate area of polygons using the
field calculator.
When I use this projection & calculate area it is incorrect. I presume it is in
decimal degrees.
Is there a way to calculate metres/kilometres squared. I presume I need to
change from a geographic coordinate system to a projected coordinate
system.Ideally this would be Hartebeesthoek94/L027, but i cannot see any of the
South African LO systems available to me.
Any help would be very much appreciated.
Thanks,Claire
