I've been trying to add correct coordinates to my grid in GIS.

I have a map of the Iberian Peninsula using an Open source layer from OSM/Stamen (CRS: EPSG:3857. WGS 84 Pseudo Mercator) and while in the print composer, after adding the grid this is what iI get:

Map I created in Print Composer

Now, these coordinates do not make any sense to me. I know that they are related to the Interval units and offset but I am quite unsure how to apply correct coordinates on my map. So please tell me how to correct the showing coordinates!

Size of the map

  • You want the coordinates in lat/long degrees?

  • @IanTurton In the Iberia Peninsula latitude should be, in decimals, around 35 and 43. Longitude should be between 0 and -10 which is not happening. The values in the grid make no sense to me, but maybe there's something about them that I don't understand... Perhaps i'm using the wrong CRS? Nov 9, 2017 at 10:07

Your grid coordinates are in the map projection by default, so in your case, they are in meters from the Equator and Greenwich.

If you look under Draw "Grid 1" grid you will see a button for CRS if you change this to EPSG:4326 your grid will be in degrees.
