Rubber Sheeting and Geographic Referencing

LAND INFO has the capability to custom geo-reference a variety of scanned documents:

• Navigational Charts
• Soil Maps
• Geologic Maps
• Aerial Photography
• Survey Drawings
• Legacy Maps

To perform the most accurate georeferencing, the document will need to have some type of geographic coordinate grid. If the map or image does not have a geographic coordinate grid, but has other features that can be geographically located (control points), then a rubber sheet can be performed.

Rubber sheeting is the process of taking a number of control points and matching them with accurate geographic locations. The image is then transformed and can be overlaid with other georeferenced data.
