Generating digital terrain models, e.g. for agricultural cost optimisation, forestry, construction or cartography

摘要

The method involves using GPS systems. Spatial coordinates (x,y,z), including altitude information, are acquired during land processing by machines (8) fitted with a position determination system (12) such as GPS. The spatial coordinates from the position determination system are stored in digital form. The stored digitised spatial coordinate information is processed into a terrain relief model which is displayed on a screen, communicated to another computer by cable or radio and output to a printer or storage medium. It can be printed or displayed in three-dimensional form.
