LandSerf is a freely available Geographical Information System (GIS) for the visualisation and analysis of surfaces developed by Dr. Jo Wood. Since its release at the giCentre, City University, LandSerf has been downloaded over 27,000 times. Potential applications include visualisation of landscapes; geomorphological analysis; gaming development; GIS file conversion; map output; archaeological mapping and analysis; surface modelling and many others. LandSerf allows for integration with Garmin GPS receivers and runs on any platform that supports the Java Runtime Environment.
Some of the most important features include the handling of multiple surface models - raster digital elevation models (DEMs), vector Triangulated Irregular Networks (TINs), contours and metric surface networks (MSNs). In addition, interactive 3D viewing and 'flythrough' of surfaces is supported on platforms that use the OpenGL API. A range of powerful and interactive visualisation techniques used in LandSerf include lighting/shade models, multiple image blending and dynamic graphical query. Other features include raster and vector transformation such as image rectification and map projection as well as multi-scale surface processing based on quadratic regression.
