LandSerf Version 1.8

LandSerf is designed for the visualisation and analysis of continuous (terrain) surfaces. It is freely available for any platform that supports Java.

Features

• Handles 4 types of surface model - raster digital elevation models (DEMs), vector Triangulated Irregular Networks (TINs), contours and metric surface networks (MSNs).
• Full 32 bit rendering with transparency if hardware supports it.
• Surface visualisation including lighting/shade models, multiple image blending.
• Interactive 3D viewing and 'flythrough' of surfaces on platforms that support OpenGL.
• Multi-scale surface processing based on quadratic regression.
• Fractal surface generation for modelling and simulation.
• Multi-scale parameter and feature extraction (slope, aspect, curvature etc.).
• Dynamic statistical and graphical summaries of rasters (histograms, scatterplots, residuals etc.).
• Import and export of common raster and vector formats.
• Dynamic links with the Virtual Field Course (VFC) networked database (VFC hub).
