Are there different number of columns and rows in raster datasets?
After the conversion into raster files of course the number of rows and columns is different to the ones in my DEM – is there a way to fix that? (tried clipping already, no success) In the end I’ll need one single landuse file with the different categories (probably there’s a easier way to achieve that!?)
How to get the last cell number in raster?
Cell numbers start at 1 in the upper left corner, and increase from left to right, and then from top to bottom. The last cell number equals the number of cells of the Raster* object. matrix of x and y coordinates, or a SpatialPoints or SpatialPointsDataFrame object Logical. If TRUE, the fraction of each cell that is covered is also returned
Why are my rasters not the same in ArcGIS?
However I found that sometimes, if the grid cells of the raster do not overlap perfectly, i.e. the two rasters are not perfectly georeferenced, Clip might retrieve a result with a slightly different number of columns and rows, generally a difference of 1.
How to reproduce raster with same extent and raster analysis?
Set both Processing Extent and Raster Analysis to the extent of the layer to which you wish to clip, and set also your Cell Size to the cell size of the clip raster (not the input raster). In QGIS use GRASS plugin thru Sextante would be the quickest way, alternatively do directly through GRASS.
How to specify number of rows and columns?
I want to produce a raster file with a specific number of rows and columns – 300×300. This needs to be reproducible on multiple data sets/locations – so fixing the extent of the file won’t work.
Is there simple way to specify number of columns and rows in ArcGIS?
I have tried changing the grid size which then changes the number of rows and columns but it is too awkward to make it create a 300×300 raster. Is there a simple way of specifying these? If this is going to be a spatial dataset and you are posting this question on a GIS forum you need to set the extent and ideally the coordinate system.
