 Introduction: Returns the upper left X and Y coordinates of the given row and column of the given raster geometric units of the geo-referenced raster as a Point geometry. If any out of bounds values are given, the X and Y coordinates of the assumed point considering existing raster pixel size and skew values will be returned.

 !!!note
     This method assumes that the spatial influence of a variable diminishes with distance. In geospatial analysis, this means features or phenomena closer to a point of interest are given more weight than those further away. For example, in environmental data analysis, measurements from nearby locations have a greater impact on interpolated values than distant ones, reflecting the natural gradation and spatial continuity.

If any data value within a raster band matches the specified noDataValue, it will be replaced and cannot be distinguished or recovered later.
