Landscape Heightfield Editor

Overview
GenesisII's Landscape Heightfield Editor is used to edit the shape of a landscape surface. You can import and export landcapes, from digital terrain files or define your own landscape from scratch.

Surface shape information is held in the form of a rectangular grid. Each grid (sample) point defines the height of the surface at that point as well as certain other characteristics. The grid dimensions are arbitarily defined as meters, but in practise may be regarded as any unit.

The Landscape Editor
The landscape editor has three main parts:

• A Toolbar that gives access to the tools you will require to define the map plus redraw, zoom in/out buttons and information about the current position of the cursor on the map in terms of grid reference and georeference position.
• The Parameter Display area down the left hand side of the window which shows various status information about the map and the tools being used.
• An initially blank area representing the Canvas used to define the map.

Defining the landscape surface
Before viewing a landscape with GenesisII you must define the shape of the surface that you wish to model. GenesisII offers several ways to import data from files. Once imported a powerful set of surface manipulation tools can be used to edit the surface, or indeed create a surface from scratch.
