CUDA-accelerated GIS and spatiotemporal algorithms
Hi there, I was wondering if this lib offers a way for me to project a large `cudf` from lon/lat to UTM zone (e.g. [`.to_crs()` in Dask GeoPandas](https://dask-geopandas.readthedocs.io/en/stable/docs/reference/api/dask_geopandas.GeoDataFrame.to_crs.html#dask_geopandas.GeoDataFrame.to_crs))? Many thanks...

In general, `polyline` and `linestring` both refers to a data structure that contains multiple points with the line segments that connect the points. `Linestring` is standardized in GIS systems through...
During #523 , I noticed many methods in cuSpatial are documented in one place, but the actual definition is in another. For example: **Location of incorrect documentation** `polyline_bounding_boxes` is under...
**Is your feature request related to a problem? Please describe.** cuSpatial as of `22.06` can now generate the minimum distance between two linestrings - it would be a nice addon...
**Is your feature request related to a problem? Please describe.** I wish cuSpatial could find the SSPD (Symmetric Segment-Path Distance) of trajectories https://arxiv.org/abs/1508.04904 **Describe the solution you'd like** As this...
We made a decision in the past to base the libcuspatial API on libcudf. Specifically, `cuspatial::` APIs take `cudf::column` and `cudf::table` inputs. Internally, these APIs use `cudf::type_dispatcher` to dispatch on...
