Digitizing Vector
Scanning Raster
From image processing of remotely
sensed data Image (Raster)
Spatial data stores location of geographic features, along with attribute
information describing what these features represent. The spatial data is stored
in a vector or raster data structure, and corresponding attribute data is stored
in a set of tables .

control points in the X and Y Coordinate fields, then
type to each record
Check The Root Mean Square (RMS) that it should
be lower than the Error Limit.
Click Register button, once it is activatedIf the calculated error is larger than the Error Limit, you cannot register your map, and you’ll have to do one of the following:• Re-digitize control points on your paper map.• Re-enter the corresponding ground control points.• Increase the value in the Error Limit edit box and press TAB key.
The value of the Error Limit field can be increased depending on the scale of map and accuracy level. To maintain highly accurate geographic data, the RMS should be kept under 0.004 inches in page units. For less accurate data, the value can be as high as 0.008 inches or its equivalent measure.
