Note

cuSpatial depends on cuDF and RMM from RAPIDS.

cuProj is a new RAPIDS library housed within the cuSpatial repo that provides GPU-accelerated transformations of coordinates between coordinate reference systems (CRS). cuProj is available as of release 23.10 with support for transformations of WGS84 coordinates to and from Universal Transverse Mercator (UTM) 🌐.

To learn more about cuProj, see the Python cuProj README or the c libcuproj README.

cuSpatial accelerates vector geospatial operations through GPU parallelization. As part of the RAPIDS libraries, cuSpatial is inherently connected to cuDF, cuML, and cuGraph, enabling GPU acceleration across entire workflows.

cuSpatial represents data in GeoArrow format, which enables compatibility with the Apache Arrow ecosystem.

cuSpatial's Python API is closely matched to GeoPandas and data can seamlessly transition between the two:

import geopandas
from shapely.geometry import Polygon
import cuspatial

p1 = Polygon([(0, 0), (1, 0), (1, 1)])
p2 = Polygon([(0, 0), (1, 0), (1, 1), (0, 1)])
geoseries = geopandas.GeoSeries([p1, p2])

cuspatial_geoseries = cuspatial.from_geopandas(geoseries)
print(cuspatial_geoseries)

Output:

0    POLYGON ((0 0, 1 0, 1 1, 0 0))
1    POLYGON ((0 0, 1 0, 1 1, 0 1, 0 0))

For additional examples, browse the complete API documentation, or check out more detailed notebooks. the NYC Taxi and Weather notebooks make use of cuSpatial.

cuSpatial is constantly working on new features! Check out the epics for a high-level view of our development, or the roadmap for the details!

• Spatial relationship queries (DE-9IM)
• Linestring-Linestring Intersections
• Cartesian distance between any two geometries (ST_Distance)
• Haversine distance
• Hausdorff distance
• Spatial window filtering

• Quadtree indexing
• Spatial joins
• Quadtree-based point-in-polygon
• Quadtree-based point-to-nearest-linestring

• Deriving trajectories from point location data
• Computing distance/speed of trajectories
• Computing spatial bounding boxes of trajectories

Thanks to the from_geopandas and to_geopandas functions you can accelerate what cuSpatial supports, and leave the rest of the workflow in place.

CUDA/GPU requirements

• CUDA 11.2 with a compatible, supported driver
• Volta architecture or newer (Compute Capability >=7.0)

Use the RAPIDS Release Selector, selecting Docker as the installation method. All RAPIDS Docker images contain cuSpatial.

An example command from the Release Selector:

docker run --gpus all --pull always --rm -it \
    --shm-size=1g --ulimit memlock=-1 --ulimit stack=67108864 \
    -p 8888:8888 -p 8787:8787 -p 8786:8786 \
    nvcr.io/nvidia/rapidsai/notebooks:24.12-cuda11.8-py3.12

To install via conda:

Note cuSpatial is supported only on Linux or through WSL, and with Python versions 3.10, 3.11, and 3.12.

cuSpatial can be installed with conda from the rapidsai channel:

conda install -c rapidsai -c conda-forge -c nvidia \
    cuspatial=24.12 python=3.12 cudatoolkit=11.8

We also provide nightly Conda packages built from the HEAD of our latest development branch.

See the RAPIDS installation documentation for more OS and version info.

To install via pip:

Note cuSpatial is supported only on Linux or through WSL, and with Python versions 3.10, 3.11, and 3.12.

The cuSpatial pip packages can be installed from NVIDIA's PyPI index. pip installations require using the matching wheel to the system's installed CUDA toolkit.

• For CUDA 11 toolkits, install the -cu11 wheels
• For CUDA 12 toolkits install the -cu12 wheels
• If your installation has a CUDA 12 driver but a CUDA 11 toolkit, use the -cu11 wheels.

pip install cuspatial-cu12 --extra-index-url=https://pypi.nvidia.com
pip install cuspatial-cu11 --extra-index-url=https://pypi.nvidia.com

To build and install cuSpatial from source please see the build documentation.

If you find cuSpatial useful in your published work, please consider citing the repository.
