Software Tools

The following applications are freely available for working with planetary data.

  

CSFD Tools

A tool to conduct crater size-frequency distribution measurements from shapefiles. The application supports 'traditional crater counting', 'buffered crater counting', 'non-sparseness correction', and 'buffered non-sparseness correction' measurements. The results can be used for further statistical analysis with Craterstats.

For additional information and support, please contact Christian Riedel.

Description of the software:

Riedel, C., Michael, G. G., Kneissl, T, Orgel, C., Hiesinger, H., and van der Bogert, C. H., A New Tool to Account for Crater Obliteration Effects in Crater Size-Frequency Distribution Measurements, Earth and Space Science, 5(6), 258-267, DOI: 10.1002/2018EA000383, 2018.

CraterTools

CraterTools is an ArcGIS add-in for map-projection-independent crater size-frequency measurements. The software requires an ArcGIS 10.1 installation on Windows 7 or higher. The zip-file contains the CraterTools add-in as well as a software manual in pdf format.

For additional information and support, please contact Dr. Thomas Kneissl or Alicia Neesemann.

Description of the software:

Kneissl T., van Gasselt S., Neukum G., Map-projection-independent crater size-frequency determination in GIS environments — New software tool for ArcGIS, Planetary and Space Science, 59, 1243-1254, DOI: 10.1016/j.pss.2010.03.015, 2011.

The Buffered Crater Counting (BCC) technique available in the software is described in:

Kneissl, T., Michael, G. G., Platz, T., Walter, S. H. G., Age determination of linear surface features using the Buffered Crater Counting approach – Case studies of the Sirenum and Fortuna Fossae graben systems on Mars. Icarus, 250, 384-394, DOI: 10.1016/j.icarus.2014.12.008, 2015.

The correction of topography-related distortions is covered in:

Kneissl, T., Schmedemann, N., Neesemann, A., Raymond, C. A., Russell, C. T., Crater Counting on Small Bodies - The Influence of Topography-Related Distortions. Lunar and Planetary Science Conference, Abs., Vol. 45, #2398, 2014.

Craterstats 2.0

A revised program for plotting crater counts and determining surface ages. The software plots isochrons in cumulative, differential, R-plot and Hartmann presentations, and makes isochron fits to both cumulative and differential data. Hartmann-style piecewise production functions may also be used.

The software requires installation of the free IDL virtual machine (IDL 8.7 or newer versions), and runs on all common platforms.

The dating of resurfacing processes is covered in:

Michael G.G., Neukum G., Planetary surface dating from crater size-frequency distribution measurements: Partial resurfacing events and statistical age uncertainty, Earth and Planetary Science Letters, 294 (3-4), 223-229, 2010.

The possibility of analysing a crater population for the presence of non-random sub-populations which could bias a measurement is covered in:

Michael G.G., Platz T., Kneissl T., Schmedemann N., Planetary surface dating from crater size-frequency distribution measurements: spatial randomness and clustering, Icarus, 2012.

The technique for fitting isochrons to differential data (Hartmann-style), and a correction of the Werner & Tanaka (2010) Mars epoch boundaries are described in:

Many application examples for diverse types of unit are given in:

Equalise2external

This command-line program carries out image brightness equalisation using an external reference image. It is intended as a pre-processing step before assembling a mosaic.

The software requires installation of the free IDL virtual machine, and runs on all common platforms (if a full IDL license is available, it will run without the splash screen). A GDAL installation is also required.

Colourscale

A DTM colourisation tool. Permits the definition of an elevation palette, adjusting the heights where the pure colours occur and generating smooth transitions in between. Reads DTMs in PDS or VICAR format, and exports colourised .tif files. Generates annotated colour-scale bar (postscript format).

The software requires installation of the free IDL virtual machine, and runs on all common platforms.

HRSCview local version

A version of HRSCview which allows you to view and manipulate locally stored map-projected PDS or VICAR format HRSC datasets. Includes some facilities for plotting elevation profiles, measuring areas and volumes, measuring crater diameters.

The software requires installation of the free IDL virtual machine, and runs on all common platforms.

VICAR

Software to display the images, to convert to other image formats, and to process to higher data levels.

BZIP2

The software bzip2 is a high-quality data compressor for the level-4 data hosted at Freie Universität Berlin.
