To better serve clients, Tekmap Consulting continually develops and updates its GIS tools and applications. This includes contributing to core GRASS programs and developing custom programs and GUIs for GRASS and MB-System.
Tekmap develops several custom GIS Tools using the GTK+ programming language. GTK+ is "a multi-platform toolkit for creating graphical user interfaces", with ports to Linux, WIN32, Mac OS X, and Direct FB.
Tekmap's GIS tools include:
- GRASS GTK+ — A GTK interface to the GRASS GIS.
- GTK+ MB-System — A GTK interface using the mbio library.
- SonarWave Lite — A .NET interface for viewing XTF sidescan and sub-bottom data (freeware).
- Profile Plotter — A GTK cross section plotting utility for geographic data.
- Ice Scour Tracking software (C as GRASS modules).
- Multibeam Navigator (C#, .Net).
