Build RELATIVE Digital Elevation Models

Build RELATIVE Digital Elevation Models

(currently only .BIL-Files)

For all values Z(x,y) in a DEM the following filter rule is applied:

1. Calculating the mean Elevation Z_mean(x,y)
within a Radius R

2. Z_relative(x,y) = Z(x,y) – Z_mean(x,y)

Radius R:

The radius influences the position of  the local extreme values. Good results can be achieved by using the average [...]

Corridor Along Line

Corridor Along Line

Draws a corridor along all line features provided in a SHP-File
This corridor is built out of multiple area features, properties of the line feature (e.g. elevation) are inherited.

Possible usage:
-  Add width / diameter to line features (e.g. streets or dikes)
-  Use Corridor to modify elevation values in DEMs along line features
-  Draw output frames [...]

Clean Digital Elevation Models

Clean Digital Elevation Models

(currently only .BIL-Files)

Many digital elevation models still have some errors, like gaps with no data values or trees, cables etc.
This simple tool will replace obviously wrong elevation data values with interpolated values from its neighbourhood.

For all values Z(x,y) in a DEM
the following filter rule is applied:

1. Calculating the mean Elevation Z_mean within [...]
