SHP files are vectors and we want a geoTIFF which is a raster file. We will be rasterizing your SHP vectors to a geoTIFF.
- QGIS on your computer.
Don't have it? Follow these instructions to install it.
- A .SHP file with z values, and a .PRJ file
1. Open QGIS and import your .SHP file.
2. Once successfully imported, it should appear in the Layers pane of the software.
This is normally located in the left side of the user interface.
3. Go to the Processing Toolbox pane
Expand SAGA and double-click the Rasterize tool to open it.
4. Change the following settings, then click Run.
a. Shapes—this is the shape file you want to convert to raster
b. Attribute—this is the elevation data (z values)
c. Cellsize—this is the resolution of the output raster. I set it to 1 m, but please feel free to modify this as needed.
5. The converted raster file should now added in the Layers pane.
6. Export it as a .GeoTIFF
Right click on the layer > "Export" > "Save As..."
Select GeoTIFF format and your desired coordinate system.
7. Click OK and you are done!
I still can't do it!
