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 [...]

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 [...]

DEM Conversion

Convert Digital Elevation Models into .BIL-FILES

Use single files or whole folders.

If your Elevation Data is stored in files other then 32 BIT – .BIL (Band Interleaved by Line), you can convert your data easily by using the GDAL Library (www.GDAL.org).
