Changelog#

Version 1.0.0 (2024-08-12)#

✨ First major release ✨
📦 Prepared for osmnx 2.0.0 and shipped cities.yml in pypi package.
⚙️ Added function to set log level and added python versions 3.11 and 3.12.
🔄 Merged several pull requests improving settings, README, dependencies, and project structure.
🐛 Fixed coverage for special case, tests, and code style issues.
📝 Updated README with CI/CD badges, improved documentation, and unified capitalization.
🗒️ Updated Changelog, Version, and Website Copyright.
📝 Licensed work under GNU AGPLv3.
📊 IO operations enhanced with graph reduction.
🗒️ Logging improvements: silenced numba compilation, reprojected debug messages.
⚙️ Parallelization updates: removed num_workers and chunk_size.
🧪 Testing updates: increased util coverage, added response 502 as xfail.
🆕 New features: Betweenness Centrality Cutoff, Reduced path filling.
🐛 Fixes: notebook formatting, GEOSException in tesselation, missing attribute.
🔄 Merged pull request: 🌐 Added Betweenness Centrality Cutoff.
📝 Misc changes: deactivated colormap logging, unified nodes and edges into one variable.
📊 Improved analysis scripts

📊 Unified Plot image format/suffix in config
🔢 Key Figures: lightweight results for analysis, see superblockify.partitioning.utils.get_key_figures().
💾 Lightweigth metric saving
🆔 Added ISO 3166 country codes
🏙️ City Crawling: Get cities from Springer Website Table. Useful functions to add OSM relation IDs to the cities. Moved cities to cities.yml file.
🌆 City List format specification.
🗒️ Adjust logging for better usefullness. Add and remove some log messages.
📚️ Added mamba to the installation instructions and changed standard environment name.
⬆️ Demand Change: Added Superblock aggregate statistics for the betweennesses.

✨ Second release ✨
⬆️ Integrated final graph statistics and Superblock statistics.
🏡 Moved Coverage to Codecov .
⬆️ Display basic graph stats at Partitioner initialization. Abstract base class superblockify.partitioning.base.BasePartitioner.
⬆️ Geopackage export: Resolve Superblock cell option. If set to True, the Superblock cells are resolved to polygons. Normally, only the edges are exported. Added general graph stats with OSM boundary polygon.

🔧 Sped up population distribution in superblockify.population.approximation.get_edge_population().
⬆️ Add population and density to Superblocks
🐛 Fix: Graph import projection order. Un-skewed distance attribute.

📚️ Documented approaches in reference notebooks Population Data, Street Tessellation, and Street Population Density.
⬆️ Added population preprocessing for for every tesselated edge. This enables an efficient population density aggregation for any given superblock. See modules in superblockify.population.
⬆️ Automated population data download and preprocessing of the GHS-POP - R2023A dataset <https://ghsl.jrc.ec.europa.eu/ghs_pop2023.php>.
⬆️ Added graph attribute boundary, used for calculating the total area of the city.
⬆️ Added general graph statistics superblockify.metric.graph_stats. Including spatial clustering and anisotropy.

⬆️ Added Partitioner based on Betweenness Centrality.
🐛 Fix segfault in betweenness centrality calculation caused by testcase with one node graph.

⬆️ Added Betweenness Centrality Calculation in measures, precompiled version works quick on metropolitan sized city networks.
⬆️ Added speed limit: Routing and low traffic speed overwriting. Unit can be passed when initializing a partitioner.

✨ Initial release ✨
🔧 Full rework of the restricted distance calculation. Runs quicker and is more memory efficient. Also, path finding had a bug in the previous version.
