Preview of new LandSerf 2.0 FeaturesLandSerf 2.0 has been completely rewritten, taking advantage of the latest Java functionality.
The result is an attractive, more powerful and easier to use package for analysing and visualising
surfaces. Here are some of the highlights...

New Graphical User Interface
LandSerf now uses a customised Graphical User Interface with keyboard shortcuts and a consistent look and feel.
Much of the common functionality can be accessed from a toolbar at the top of the screen. Thumbnail previews
of stored surface models are shown at all times.

New Functionality
LandSerf 2 contains new functionality such as rectification of non-georeferenced images, allowing scanned
rasters and images to be georeferenced and combined with other spatial models. Rasters and vectors referenced
with global lat/long coordinates can be projected onto UTM or OS National Grid coordinate systems. Rasters can
now store 'null' values that do not get processed. This is useful for representing missing data and water/islands.
Improved vector handling can now handle areas, islands and 'holes' as well as import of GML and Shapefile format vector
maps.

Interaction
All surface models can now be interactively 'zoomed' and 'panned'. This provides a convenient tool for the
exploration of scale dependencies in models. The 3d viewer has been significantly enhanced with the addition
of 'collision detection' (no more tunnelling though mountains), added user-defined surface detail and improved
navigation with the mouse.

||||
Performance
With a rewriting of the LandSerf code come significant performance and efficiency gains. Spatial files are now
compressed on loading and saving. The 3d viewer is faster and takes advantage of recent developments in OpenGL
and graphics accelerators. Vector handling is faster and rendering higher quality.

Design
LandSerf has been re-engineered to be more object oriented. This makes it easier for users to add their
own code, and should speed up the time taken to add future updates. The object-oriented spatial model
design is fully documented.
