Metadata APIs

The Metadata APIs provide metadata information about the Raster dataset. Below are the different Metadata APIs:

Raster Information (getRasterInfo): This method returns information about a raster dataset as RasterInfo Object. This RasterInfo object includes Name of the Raster, Base Level, CoordSysString, FieldInfo, Height, Width, Overview, etc.

Raster Statistics (getStatistics): This method returns basic statistics information of Raster Dataset as RasterStatistics Object for given field and band index. This RasterStatistics object includes information like Minimum, Maximum, Mean, Median, Mode, Area, Cell Difference, Standard Deviation, etc.

Cell Value (getCellValue): This is a function to get the valid Cell Value at Grid Coordinates cellX and cellY in the form of a CellValue Object. Cell Value could be Number or String depending upon Raster band. It also contains information about the Status of the CellValue object whether it is VALID, NO_DATA, OUT_OF_BOUNDS or ERROR.
