I am following this tutorial to attempt to determine flooding in the Gulf region based on estimated rises in sea level.
I have taken topographic maps from the USGS and used to contouring tool to turn them into contour maps and assign elevation data to the maps; that step has gone without issues. However, when following the tutorial to create the TIN models that are theoretically used in the raster calculator, I get very strange results.
Am I doing something wrong with settings in the interpolation plugin? Or is there a more efficient way to complete this task?
Photo of the strange results and my settings. The green region is the generated contour map for Florida, while the black region is the TIN model.
The region I'm working with is substantially larger than the region in the tutorial, which may be having an effect one results, but I have not been able to find an alternative method to use.
