BuildIrregularGridMetaspatialRaster
| |
|
BuildMetaspatialRaster
| This task constructs an ENVIRaster from an array of source rasters that overlap or contain gaps in coverage. |
|
ClassificationClumping
| This task performs a clumping method on a classification image. |
|
ClassificationSieving
| This task removes isolated classified pixels using blob grouping. |
|
ConvertGeographicToMapCoordinates
| This task converts geographic (latitude/longitude) coordinates to map (northings/eastings) coordinates. |
|
ConvertMapToGeographicCoordinates
| This task converts map (northings/eastings) coordinates to geographic (latitude/longitude) coordinates. |
|
ConvertMapToPixelCoordinates
| This task converts map (northings/eastings) coordinates to pixel coordinates. |
|
ConvertPixelToMapCoordinates
| This task converts pixel coordinates to map (northings/eastings) coordinates. |
|
Custom Task Base Classes
| A custom base class maps the parameters from your IDL procedure to an ENVITask. |

Custom Tasks
| |
|
Data Processing using ENVITask
| |
|
ENVI_SMACC_DOIT
| Performs Sequential Maximum Angle Convex Cone (SMACC) processing. |
|
ENVIAbortableTaskFromProcedure::DoExecute
| This method is called by ENVITask::Execute after a successful call to the PreExecute method. |
|
ENVIAbortableTaskFromProcedure::PostExecute
| This method is called by ENVITask::Execute after a successful call to the DoExecute method |
|
ENVIAbortableTaskFromProcedure::PreExecute
| This method is called first when ENVITask::Execute runs. |
|
ENVIAdditiveLeeAdaptiveFilterTask
| Applies a Lee adaptive filter to smooth noisy data that has an additive component. |
|
ENVIAdditiveMultiplicativeLeeAdaptiveFilterTask
| Applies a Lee adaptive filter to smooth noisy data that has both an additive and a multiplicative component. |
|
ENVIAutoChangeThresholdClassificationTask
| This task uses pre-defined thresholding techniques to automatically classify change detection between two images. |
|
ENVIBinaryGTThresholdRasterTask
| Creates a new raster where values above a specified threshold are set to 1 and all other values are set to 0. |
|
ENVIBinaryLTThresholdRasterTask
| Creates a new raster where values below a specified threshold are set to 1 and all other values are set to 0. |
|
ENVIBitErrorAdaptiveFilterTask
| Applies a bit error adaptive filter to a raster, to remove bit-error noise, which is usually the result of spikes in the data caused by isolated pixels that have extreme values unrelated to the image scene. |
|
ENVIBuildBandStackTask
| Builds a band-stacked raster (also called a metaspectral raster), which is a stack of ENVIRasters with the same dimensions. |
|
ENVIBuildGridDefinitionFromRasterTask
| Returns a grid definition, which provides the information needed to georeference rasters to a common coordinate system. |
|
ENVIBuildLayerStackTask
| Builds a layer-stacked raster from a set of rasters that will be regridded to a common spatial grid. |
