LandSerf

LandSerf is a freely available Geographical Information System (GIS) for the visualisation and analysis of surfaces. Applications include visualisation of landscapes; geomorphological analysis; gaming development; GIS file conversion; map output; archaeological mapping and analysis; surface modelling and many others. It runs on any platform that supports the Java Runtime Environment (Windows, MacOSX, Unix, Linux etc.)

Features:

• Handles multiple surface models - raster digital elevation models (DEMs), vector Triangulated Irregular Networks (TINs), contours and metric surface networks (MSNs).
• Interactive 3D viewing and 'flythrough' of surfaces on platforms that support OpenGL.
• A range of powerful and interactive visualisation techniques including lighting/shade models, multiple image blending and dynamic graphical query.
• Raster and vector transformation including image rectification and map projection.
• Multi-scale surface processing based on quadratic regression.
• Fractal and polynomial surface generation for modelling and simulation.
• Multi-scale parameter and feature extraction (slope, aspect, curvature etc.).
• Import and export of common raster and vector formats.
• Integration with Garmin GPS receivers.
