I have a geotiff file that is a 1kmx1km image of a specific location. I want to display a map that is limited to my image, and I need the map coordinates to correlate to the coordinates in my image. (Eventually I'm going to put markers on given coordinates within that square km).
I've been unable to make the 'world coordinates' of the map line up with the geotiff data. My image has the coordinates stored in it.
I installed QGIS, and with that I can see the coordinates of the building on my map (8.387607, 46.791225).
When I run my program, however, it lists the building coordinates as 27.377929, 29.355468.
What do I need to do so that my map reads & uses the coordinates from the tiff file, instead of using a full set of world coordinates across the display?
