ComputeFootprintByGeometry
The ComputeFootprintByGeometry ISCommand is used to redefine the footprint polygon for each raster dataset by considering the warping once the raster dataset is georeferenced.
The command line is:
ISCommand ComputeFootprintByGeometry --ISDef=<PathToISDef> --MaxNumVertices=<Approx. Number of vertices> --ShrinkWidth=<ShrinkWidth> --ShrinkHeight=<ShrinkHeight> --Refine=[TRUE|FALSE] --SkipDerivedImages=[TRUE|FALSE] --NoData=<NoDataValue>
The table below defines the variables that are required to use this script. Most variables are defined within the script. You can either make an edit to the script or enter the variable at the command line as shown below.
Variable |
Description/Options |
Default |
Required |
ISDef |
Path and name of the image service definition file. |
User specified |
Yes |
MaxNumVertices |
Defines the maximum number of vertices in the footprint polygon. It should not be less than 4. |
30 |
Yes |
ShrinkWidth |
Shrinks the columns of the footprint by a percentage. |
0 |
Yes |
ShrinkHeight |
Shrinks the rows of the footprint by a percentage. |
0 |
Yes |
Refine |
This property should be false if the existing footprint is invalid. |
FALSE |
Yes |
SkipDerivedImages |
This property should be false if the footprints of the derived images need to be recomputed |
TRUE |
Yes |
NoData |
This property should be false if the existing footprint is invalid. |
|
No |
Example:
ISCommand ComputeFootprintByGeometry --ISDef=c:\Test1.ISDef\ImageService.ISDef --MaxNumVertices=30 --ShrinkWidth=0 --ShrinkHeight=0 --Refine=FALSE --SkipDerivedImages=TRUE --NoData=TRUE
