Zones of nightlights in the Tokyo, Japan area. Var vectors = zones.addBands(nl2012).reduceToVectors() and the mean of the nightlights band, since the mean For further help about how our data can transform your organisation, contact us. Up to now, ive been converting polygons to raster using the origin. However, the raster was too coarse (1km square cells) and I needed to make it a finer grid (50m2) so as to allow the best resoultion output possible with my data. The source file I have for that are is a raster. Convert the zones of the thresholded nightlights to vectors. In GIS OS MasterMap can be viewed over a considerable range of scales. I need to make a grid that conforms to an existing project area.
