Rubber Sheeting, Geographic Referencing, Metadata &
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
After maps have been geo-referenced, Esri .shp or other vector indexes are created; in addition LAND INFO can create metadata based off the legend/marginalia of the map documents.
