Hi! Thanks a lot by the video! To do a bathymetry map using Tanaka Contours, is necessary some modification? The deep parts of my map are looking like islands. Thanks again!
@@KlasKarlsson I did some research on this, and realized that I should make some adjustments when working with bathymetry rather than relief, because for one case it would be a concave approach and for another a convex approach. Paper: icaci.org/files/documents/ICC_proceedings/ICC2001/icc2001/file/f24028.pdf I do not know if I got the best possible result, but a slight adjustment in the expression (+45 instead of -45) led to an excellent result: color_hsl (0,0, scale_linear ( abs ( (if ("azimuth"
Use the "Processing Tool" from GDAL called "Clip Raster By Extent" (just search for it in the processing toolbox). That will help you clip your raster elevation layer to the map canvas extent, or from your manual selection on screen.
but in qgis 3.2 is it no longer possible to do it that way because it uses python 3 instead of python 2? It is right? even the model (tanaka_contour.model) that has anita in github, can not load in qgis 3.2 how to solve that?
