Hello,
Im dealing with QC and i have to make some calculations related to a combination of extent coordinates and resolution, the question is that i find differences in Gm 22.0 b101920 challenged to QGIS extent... I thought there was just an extent...
Could you please let me know what do you think about it?
Thanks in advance,
Alberto

Hello,
In the metadata for a DTM, the UPPER LEFT and LOWER RIGHT values represent the center of the upper left and lower right pixels in your data. Since each pixel is 5 meters square, the true boundary would be found by expanding the rectangle by 2.5 meters in each direction. To see the actual bounds:- Right-click on the layer in the Control Center
- Choose Layer > BBOX/COVERAGES... Click the Yes button to create a rectangular area feature.
- After the new layer is added to the Control Center, view its Metadata to see the bounding coordinates.
