Remarks
|
GeoDataset |
an input Raster, RasterDataset, RasterBand, or RasterDescriptor |
|
sourceControlPoints |
The source points are the "from" coordinates of the links. |
|
targetControlPoints |
The target points are the "to" coordinates of the links. |
|
transformType |
an esriGeoTransTypeEnum specifying the geometric transformation type. There are three types, specifying the order of the polynomial. Higher order values will fit a more complex surface. esriGeoTransPolyOrder1 - A first order polynomial fits a flat plane to the input points. This is default. esriGeoTransPolyOrder2 - Transformation is a second order polynomial esriGeoTransPolyOrder3 - Transformation is a third order polynomial. |
|
resampleType |
an esriGeoAnalysisResampleEnum specifing the resampling algorithm to be used when sampling a Raster can be of type: esriGeoAnalysisResampleBilinear - bilinear interpolation. This is Default. esriGeoAnalysisResampleCubic - cubic convolution. esriGeoAnalysisResampleNearest - nearest neighbor assignment. |
