Momepy

Requirements:

- momepy now requires GeoPandas 0.8 or newer
- momepy now requires pygeos
- momepy now (optionally) requires mapclassify 2.4.2 or newer

API changes:

- ``network_false_nodes`` is now deprecated. Use new ``remove_false_nodes`` instead.

Enhancements:

- New performant algorithm ``remove_false_nodes`` to remove nodes of a degree 2 of a LineString network. (204)
- Faster ``CircularCompactness`` (205)
- pygeos-based ``Tessellation`` (207)
- New class ``Percentiles`` (209)
- Various speedups (209)
- New ``enclosures`` function (211)
- Enclosed tessellation option in ``Tessellation`` (212)
- Preprocessing module (214)
- Preprocessing function to ``close_gaps`` of LineString geoemtry (215)
- Preprocessing function to ``extend_lines`` (217)
- ratio-based network links (218)
- vectorize ``StreetProfile`` (219)
- capture MutliLineString in ``Linearity`` (236)
- support MultiPolygons (234)
- handle NaNs in ``limit_range`` (235)
- ``SharedWalls`` length (238)
- refactor ``Blocks`` using overlay and libpysal (237)
- more options in converting to networkx graphs in ``gdf_to_nx`` (240)
- use mapclassify.classify in ``Simpson`` and ``Shannon`` (241)

Bug fixes:

- fix nearest neighbor in ``get_network_ratio`` (224)
- ``Tessellation`` error when geom collapsed (226)
- ``Blocks`` empty difference (230)

New documentation and a lot of performance improvements.

To get the best performance, it is recommended to use `geopandas>=0.8` and have `pygeos` installed.

API changes:

- ``Convexeity`` is now ``Convexity`` (171)
- ``local_`` centrality (betweenness, closeness, straightness) has been included in respective global versions (178)

New features:

- ``CheckTessellationInput`` to check building footprint data for potential issues during ``Tessellation`` (163)
- On demand ``DistanceBand`` spatial weights (neighbors) for larger weight which would not fit in memory (165)

Enhancements:

- New documentation (167)
- Support network analysis for full network (176)
- Options for ``preprocess`` (180)
- Expose underlying ``simpson`` and ``shannon`` functions (183)
- ``MeanInterbuildingDistance`` performance (187)
- ``StreetProfile`` performance refactor (186)
- Retain attributes in ``network_false_nodes`` (189)
- Performance improvements in ``elements`` module (190)
- Performance refactor of ``SharedWallsRatio`` (191)
- Performance refactor of ``NeighboringStreetOrientationDeviation`` (192)
- Minor performance improvements (193, 196)
- Allow specification of verbosity (195)
- Perfomance enhancements in ``sw_high`` (198)

Bug fixes:

- ``Density`` TypeError for islands (164)
- Preserve CRS in ``network_false_nodes`` (181)
- Fixed ``Squareness`` for non-Polygon geom types (182)
- CRS lost with older geopandas (188)

Bug fix release.

- fixed regression causing `MeanInterbuildingDistance` failure (161)

Version 0.2.0 with several updates, one minor API change and significant performance improvements.

API changes:

- `AverageCharacter` allows calculation of multiple modes (mean, median, mode) at the same time. Each can be accessed via its own attribute. Apart from `mean`, none is accessible using `.series` anymore. (147)

Enhancements:

- `Shannon` index (158)
- `Simpson` allows Gini-Simpson and Inverse Simpson index modes (157)
- Diversity classes support categorical values (159)
- `SegmentsLength` allows sum and mean at the same time (146)
- `AverageCharacter` allows calculation of multiple modes (mean, median, mode) at the same time (147)
- Better compatibility with OSMnx Graphs (149)
- `Orientation` support LineString geometry (156)
- `AreaRatio` for uneven number of features (135)
- Performance improvements (144, 145, 152, 155)

Bugfixes:

- float precision errors in `network_false_nodes` (133)
- `network_false_nodes` for multiindex (136)
- `BlocksCount` no neighbors error (139, 140)
- LineString Z support in `nx_to_gdf` (148)
- accidental 'rtd' print (150)
- `CentroidCorner` may fail for Polygon Z (151)

Small bug-fix release bringing following changes:

- fix for ``AreaRatio`` resetting index of resulting Series (127)
- fix for ``network_false_nodes`` to work with GeoSeries (128)
- fix for incomplete spatial_weights and missing neighbors. Instead of raising KeyError
momepy now returns np.nan for affected row. np.nan is also returned if there are no
neighbors (instead of 0). (131)

🎉 The first official release of momepy is finally here. 🎉

After a long period of beta and RC development, I am happy to announce that since today, momepy is officially released in the first stable version 0.1.0.

During the final weeks before the release, momepy was reviewed for a publication in the Journal of Open Source Software (https://github.com/openjournals/joss-reviews/issues/1807). As that is now concluded, momepy is being released together with the software paper introducing its abilities, thorough documentation ([docs.momepy.org](https://docs.momepy.org)) and user guide ([guide.momepy.org](https://guide.momepy.org)).

I have to thank the Axel and Margaret Ax:son Johnson Foundation for the support of the development of the package (as a part of The Urban Form Resilience Project), the University of Strathclyde, JOSS and namely geraintpalmer and martibosch for their thorough review of the software.
