A geometric transformation, skew and differential scaling on a rectangular object, while preserving line parallelism.
A resampling method that uses the distance-weighted average of the four nearest pixel values to estimate a new pixel values.
A resampling method that uses the distance-weighted average of the 16 nearest pixel values to estimate a new pixel value.
The process of converting a map or an image from one coordinate system to another by using a set of control points and transformation equations.
Ground control points (GCPs)
Points used as control points for an image-to-map transformation.
One type of geometric transformation that converts the rows and columns of a sattellite image into real-world coordinates.
One type of geometric transformation that converts a newly digitized map into real-world coordinates.
A resampling method that uses the nearest pixel value to estimate a new pixel value.
A technique that builds different pyramid levels for displaying large raster data sets a different resolutions.
A process of filling each pixel of a newly transformed image with a value or derived value from the original image.
Root mean square (RMS) error
A measure of the deviation between the actual location and the estimated location of the control points in geometric transformation.
