ohsome-planet: Export OSM data and its history to GeoParquet: The GIScience Research Group at Heidelberg University and HeiGIT have released version 1.0.0 of #ohsome-planet, a tool for #cloudnative access to #OpenStreetMap (#OSM) data using the #GeoParquet format. Originally developed as an internal tool, it...

๐โ We have just released ๐ผ๐ต๐๐ผ๐บ๐ฒ-๐ฝ๐น๐ฎ๐ป๐ฒ๐, a new software library on GitHub that facilitates the transformation of raw OpenStreetMap history data into the ๐๐ฒ๐ผ๐ฃ๐ฎ๐ฟ๐พ๐๐ฒ๐ format, making it more accessible and efficient for spatial data analysis.
With ohsome-planet, we make a big step toward the development of ๐ผ๐ต๐๐ผ๐บ๐ฒ ๐ฎ.๐ฌ.
๐ฐ A short read on what ohsome-planet can do: https://heigit.org/first-release-of-ohsome-planet-osm-history-data-in-geoparquet-format-2/
๐ฉ๐ปโ๐ป The ohsome-planet software library: https://github.com/GIScience/ohsome-planet/releases/tag/1.0.0
We have recently expanded the #ohsome Quality API and its dashboard, introducing a new indicator to assess attribute completeness in #OpenStreetMap.
We now add new options to the Attribute Completeness Indicator:
โซ๏ธ Multi-Attribute Queries: Check completeness for multiple attributes at once.
โซ๏ธ Custom Attribute Filters: define key-value combos with โandโ / โorโ logic.

๐บ๏ธ๐ Curious about the impact of OpenStreetMap usage?
We selected some metrics on #ohsome tools and the impact of #OpenStreetMap (#OSM) in 2024.
From building data coverage to the number of API requests, these figures showcase the scale of OSM use and the analytics capabilities of ohsome.
โน๏ธ With the ohsome dashboard, users can analyze OSMโs full-history data without programming skills.

๐ฃ๏ธ How up-to-date is road data in #OpenStreetMap?
This map shows the recency (โcurrentnessโ) of edits to #OSM road data in urban centers around the world.
Currentness is a crucial factor in determining data quality. Higher values suggest more up-to-date areas, while lower values may indicate less reliable information.
The map was created using the #ohsome quality API (OQAPI): https://dashboard.ohsome.org/#backend=oqtApi&topic=roads&indicators=currentness

#30DayMapChallenge Day 18:
๐๏ธ Todayยดs map shows where building stock is located worldwide. It highlights a particularly high building density in East and Southeast Asia.
Benjamin Herfort & al. created this map and compared it with building data in #OpenStreetMap using #ohsome (https://dashboard.ohsome.org/). They analyzed building data completeness for 13,189 urban areas in #OSM, proposing solutions for the data gaps.

๐With tools that rely on #opensource #data, data quality is a vital factor!
๐In case of the #GEEST, a tool developed by a workgroup of @worldbank, we used the #ohsome quality API (oqapi) to test if #osm and #mapillary data suit the GEEST methodology:
