[FEA] Nearest point and segment index of linestring to a point (all-pairs)

1

**Is your feature request related to a problem? Please describe.** As with #646 , given vectors of points and linestrings, for every combination point-linestring pair, compute the nearest point and...

**Is your feature request related to a problem? Please describe.** For linestring/point pairs, I would like to calculate not only the distance between points and linestrings, but also the nearest...

[DOC] Improve doxygen rendering, grouping, etc.

2

We should follow the lead of libcudf and improve our doxygen docs - [ ] Add a main_page.md - [ ] Add API groups and a tab for them -...

API to extract a subset of polygons from existing set

3

It would be great if we can have a Python API like `subset_polygon_geodataframe(geo_df,subset_ids or subset_range)` to return the same four arrays like `read_polygon_shapefile(shp_file)`. This will leave the C++ API untouched...

[FEA] Make return value order of quadtree_point_to_nearest_polyline match quadtree_point_in_polygon

4

In fixing #489 we noticed the following. `cuspatial::quadtree_point_in_polygon` returns two values: offsets of polygons, then offsets of points. https://github.com/rapidsai/cuspatial/blob/6a34c21ac13708303cda7c2fb9c49fbb42d04ed5/cpp/include/cuspatial/spatial_join.hpp#L94-L96 `cuspatial::quadtree_point_to_nearest_polyline` returns these in the opposite order. (point offset then polyline...

[FEA] Refactor trajectory APIs to header-only API

1

Create header-only APIs for the following and refactor existing APIs / tests on top of the header-only API: - [x] `cuspatial::derive_trajectories` #628 - [ ] `cuspatial::trajectory_distances_and_speeds` - [ ] `cuspatial::trajectory_bounding_boxes`...

[FEA] Refactor cubic spline APIs to header-only

1

Create header-only APIs for the following and refactor existing APIs / tests on top of the header-only API: * `cuspatial::cubicspline_interpolate()` * `cuspatial::cubicspline_coefficients()` See https://github.com/rapidsai/cuspatial/blob/branch-22.08/cpp/include/cuspatial/cubic_spline.hpp

We would like to improve cuSpatial's developer documentation to make it easier to contribute to cuSpatial. I think we should follow the lead of cuDF, which has a relatively comprehensive...

[FEA] Refactor Shapefile reader to header-only API

1

Create header-only APIs for the following and refactor existing APIs / tests on top of the header-only API: * cuspatial::read_polygon_shapefile() See https://github.com/rapidsai/cuspatial/blob/branch-22.08/cpp/include/cuspatial/shapefile_reader.hpp
