How to check for overlap between raster and Polygon?
Due to my data structure, I sometimes do not have an overlap between one of the polygons and the raster. Polygon 3 in the picture below does not have an overlap with the raster. I already have a procedure that gives me the desired results, but I still have to do ExtractByMask for all of the polygons.
When to use windowed reading and writing in raster?
Raster datasets are generally composed of multiple blocks of data and windowed reads and writes are most efficient when the windows match the dataset’s own block structure. When a file is opened to read, the shape of blocks for any band can be had from the block_shapes property.
Where can I find the shape of a window in rasterio?
When a file is opened to read, the shape of blocks for any band can be had from the block_shapes property. The block windows themselves can be had from the block_windows function.
How to check if a raster is empty?
(The way I check if the raster is empty is by checking if the mean value and the standard Deviation is equal to 0) Edit: Curtis suggested using the extent of the raster, but my raster is not continuous. Below is another picture of how I imagine an intermediary step to look like.
How to find the intersection of two Raster images?
I have two raster images, Boolean classified (1 or 2). They overlap in given areas. I need a raster that is only the overlapping sections. Using Arcinfo 10. Answer can only use raster methods, no converting to polygons, points, etc… This seems like a pretty simple clipping operation. Use the Clip (Data Management) tool.
Can a raster be used as a clip extent?
An existing raster or vector layer can be used as the clip extent. If you are using a feature class as the output extent, you have the option to clip the raster by the minimum bounding rectangle of the feature class or by the polygon geometry of the features. If clipping geometry is used, then the pixel depth of the output may be promoted.
