Make int64 casting optional

3

With 'large' raster datasets of integer datatype, rasterstats wastefully casts the ndarray read from the raster up to int64. In the extreme case, this uses 8 times more memory than...

This PR resolves a few shapely deprecation warnings: - Use `shapely.errors.ShapelyError` (`ReadingError` was also only from `shapely.errors`) - Use `geom.geom_type` instead of `geom.type` - Fix inconsistent dimensionality error with test...

I am getting a wrong value after the point query on tif files below using the shp file below. For validation, I overlapped all of them in QGIS software and...

missing `click` dependency

1

Hi, this is more a proposal than a bug report. Since python-rasterstats directly imports `click`: https://github.com/perrygeo/python-rasterstats/blob/5da3110230df44e228ba21f16a9d31ab7e84e0d5/src/rasterstats/cli.py#L6 and since there's a known issue with click=7.1` in `requirements.txt` would be great. The...

If polygons smaller than a pixel, stats not computed

1

I've found that for the polygons that happen to be smaller than the image pixel, zonal_stats returns empty results. Although there are other packages to extract pixel values from points,...

This PR is supposed to add support for zonal statistics of multiband raster data, similar to the issue raised in #73 . If you for example want to calculate the...

Proposal for a third rasterization strategy

4

Hello, Reading the [documentation](https://pythonhosted.org/rasterstats/manual.html#rasterization-strategy) about Rasterization strategy I see there are two current possible strategies: - *default* : pixel is included if its centroid is within the geometry) - *all_touched*...

Multiband support

5

`zonalstats` was originally optimized for large vector feature collections against a single raster band (i.e. thousands of polygons against a DEM raster) There is another use case which `zonalstats` doesn't...

Question: caching intermediate operations.

3

Hey hey. Great stuff. `Question:` When using `python-rasterstats` with one polygon and many rasters (or vice versa), do you see a clear spot where intermediate steps can be cached? Examples:...

handling remote files (or setting rasterio/gdal context)

2

Hi, thanks for this great package. I'm wondering if it's possible to pass an *open* raster (as opposed to simply the path) to zonalstats (without converting to `ndarray` first). My...
