Generalized shaded relief

I also provide pre-rendered and generalized shaded relief data - either as a grayscale shademap or with custom coloring. Shading is performed using a custom algorithm including adaptive illumination. The shade map is generalized for good readability and for reducing raster artefacts.

Both the shading style and the generalization settings can be adjusted for the application.

data information:
data type	generalized shaded relief
coverage	global
available projections/variants	EPSG:3857 for web maps zoom 1-6, EPSG:3031, EPSG:3995
custom production	any other projection, custom shading style
license constraints	depending on source data

Here an example for relief renderings for web map zoom levels 3 to 8

generalized shaded relief example zoom=3

generalized shaded relief example zoom=4

generalized shaded relief example zoom=5

generalized shaded relief example zoom=6

generalized shaded relief example zoom=7

generalized shaded relief example zoom=8

If you are interested in generalized shaded relief data use the form below to describe your needs and i will get back to you.

Processed elevation data

The various elevation data sets currently available all come with restrictions like limited coverage, gaps, errors and data artefacts. I provide elevation data processing to produce

seamless combination of different limited coverage data sets.
merging multiple data sources to a combined and better quality data set like merging ASTER GDEM and SRTM.
waterbody flattening.
generating high quality gridded DEMs from contour data.

data information:
data type	processed elevation data
coverage	global
available projections/variants	only custom production
custom production	on customer requests
license constraints	depending on source data
