PyGeoUtils: Utilities for (Geo)JSON and (Geo)TIFF Conversion
PyGeoUtils is a part of HyRiver software stack that is designed to aid in watershed analysis through web services. This package provides utilities for manipulating (Geo)JSON and (Geo)TIFF responses from web services. These utilities are:
json2geodf: For converting (Geo)JSON objects to GroPandas dataframe.
arcgis2geojson: For converting ESRIGeoJSON objects to standard GeoJSON format.
gtiff2xarray: For converting (Geo)TIFF objects to xarray datasets.
gtiff2file: For saving (Geo)TIFF objects to a raster file.
xarray_geomask: For masking a
xarray.DataArrayusing a polygon.
All these functions handle all necessary CRS transformations.
You can find some example notebooks here.
Please note that since this project is in early development stages, while the provided functionalities should be stable, changes in APIs are possible in new releases. But we appreciate it if you give this project a try and provide feedback. Contributions are most welcome.
Moreover, requests for additional functionalities can be submitted via issue tracker.
You can install PyGeoUtils using
pip after installing
libgdal on your system
(for example, in Ubuntu run
sudo apt install libgdal-dev):
$ pip install pygeoutils
Alternatively, PyGeoUtils can be installed from the
$ conda install -c conda-forge pygeoutils
To demonstrate capabilities of PyGeoUtils let's use
PyGeoOGC to access
National Wetlands Inventory from WMS, and
FEMA National Flood Hazard
via WFS, then convert the output to
import pygeoutils as geoutils from pygeoogc import WFS, WMS from shapely.geometry import Polygon geometry = Polygon( [ [-118.72, 34.118], [-118.31, 34.118], [-118.31, 34.518], [-118.72, 34.518], [-118.72, 34.118], ] ) url_wms = ( "https://www.fws.gov/wetlands/arcgis/services/Wetlands_Raster/ImageServer/WMSServer" ) wms = WMS( url_wms, layers="0", outformat="image/tiff", crs="epsg:3857", ) r_dict = wms.getmap_bybox( geometry.bounds, 1e3, box_crs="epsg:4326", ) wetlands = geoutils.gtiff2xarray(r_dict, geometry, "epsg:4326") url_wfs = "https://hazards.fema.gov/gis/nfhl/services/public/NFHL/MapServer/WFSServer" wfs = WFS( url_wfs, layer="public_NFHL:Base_Flood_Elevations", outformat="esrigeojson", crs="epsg:4269", ) r = wfs.getfeature_bybox(geometry.bounds, box_crs="epsg:4326") flood = geoutils.json2geodf(r.json(), "epsg:4269", "epsg:4326")
We can also save WMS outpus as raster file using
geoutils.gtiff2file(r_dict, geometry, "epsg:4326", "raster")
