toFeatureCollection
public SimpleFeatureCollection toFeatureCollection()
Description copied from class:RasterLayer
Supply a FeatureCollection indicating where the raster is located, we ask that the features use the same coordinate reference system as your raster data and form an outline or foot print of the information you have available.This is an interesting method for a RasterLayer to have; some of the rendering systems are willing to render your raster content as an outline; for this to work they need this method to supply a feature collection indicating where the content is located. The information may also be used to determine if any of your raster content is on screen (and thus needs to be rendered).
Note this is a feature collection to allow for raster content that contains more than one image; and is not based bounding boxes (as sometimes rasters are rotated or stretched into position).
You may find the
FeatureUtilities
useful in wrapping up your raster content.- Specified by:
toFeatureCollection
in classRasterLayer
- Returns:
- SimpleFeatureCollection indicating the location of raster content
