Mapping

GeoVision can produce mapping using underground, ground, airborne or satellite positioning and data collection technologies.

Very High Resolution Satellite Imagery (VHRS) is a cost-effective method to map very large areas of land at up to 1:5000 scale quickly. Satellite sensors pass the same spot on the earth every 2 days. There are no restrictions. The imagery can then be ortho-rectified to fit any projection and imported into a Geographic Information System or engineering design software to enable planning and development.

For mapping scales larger then 1:10,000 to 1:500 aerial imagery is recommended. Example of aerial imagery for golf course development.

Whilst satellite and aerial imagery provide mapping of large areas quickly, for very detailed surveys ground survey methods are preferable using total stations or GPS.

GeoVision also has experience in underground mapping using Inertial Navigation Systems. Example
