India/PMGSY rural connectivty data import
The Ministry of Rural Development, Government of India have released their live dataset of rural roads and habitations collected by local field surveys via the PMGSY rural road connectivity programme under GODL license which is compatible with OSM data.
- Data source: https://geosadak-pmgsy.nic.in/opendata/
- Github project mirror: https://github.com/datameet/pmgsy-geosadak
- Map explorer: http://projects.datameet.org/pmgsy-geosadak/map.html
- PMGSY vs OSM Habitations comparison and feedback app: https://server.nikhilvj.co.in/pmgsy/ , githup source [1]
Data quality and coverage
The dataset includes:
- 1 million+ rural habitation points (live data)
- 2.5 million+ km of rural road centerlines (live data)
- 70k+ kms of sanctioned PMGSY road proposal centerlines (live data)
- ~800k POIs of rural public facilities like school, village office, market, bus stop (static data)
- Block level administrative boundaries (static data)
Metadata
- Unique object identifiers for use internal use in the PMGSY planning, GIS and monitoring system
- Block level administrative mapping for roads, Habitation level mapping for POIs
- Road name class and owner/operator
- Habitation name and population value estimated by field engineer based on 2011 census
- POI category
Data quality
- Quality and coverage differs by state due to decentralized data collection
- Dataset regularly updated and open dataset expected to be released monthly
- May contain small amount of errors but generally good since and is used for official planning http://www.pmgsy-grris.nic.in/gis.aspx
- Roads are traced by local engineers on high resolution satellite imagery but are not topologically connected
- POI location are extracted from geotagged phone photos and may not match actual site position
- Block boundaries are not latest and should not be considered official
- Habitation locations less than 500m apart have been collapsed
Full details about the dataset can be seen in this technical presentation video by Harsh Nisar, lead data scientist at the Ministry of Rural Development.
Partnership with OSM
NRIDA is the nodal agency behind the PMGSY programme implementation and are interested to promote the open data use in establishing feedback loops to improve the dataset. The OpenStreetMap community was specifically considered to promote the data, but since the India community does not have a registered chapter, an MoU to promote the open data was signed with DataMeet.org, a registered trust representing the active open data community in India including several members of the OSM community.
Through datameet, the OSM community has a direct line of communication with NRIDA to provide faadback and grow the data partnership in future. More metadata for feature may be released based on community feedback.
Community problem statements
- Identify missing roads in dataset, determine operator for each road https://youtu.be/3tI7XIZzhSM?t=9690
- Identify missing habaitation points and mapping all habitation points to administrative revenue village boundaries https://youtu.be/3tI7XIZzhSM?t=9959
Data import
There has been active discussions on the OSM India telegram group of a possible import after reviewing the quality and data gaps with OSM. This has also been notified on talk-in
