Sentence examples for large raster from inspiring English sources
Routinely available remote sensing data on land cover are useful to study such phenomena, focus is on large raster maps of Urban Morphological Zones (UMZ) produced by the CORINE Land Cover programme of the European Environmental Agency.
In (c), the cells with little population are merged with larger raster cells in the municipality.
The tool created smaller raster cells in urban areas and larger raster cells in rural areas, and it was used successfully for a transport model.
The tool applied the quadtree algorithm and repeatedly subdivided larger raster cells into four smaller raster cells, until each raster cell had a population of no more than 5000 households.
The performance of the new algorithm was tested on a series of rasters up to 160 Mcells in size; for largest size test raster a speed up over the original algorithm is 74 times.
