kathmandu-osm-analysis

This repository contains Python scripts that check OSM data completeness and recency for tourism amenities in Kathmandu.

First, OSM data within a given geojson bounds is extracted using the osmnx python library. After this, by making requests to the Overpass API, we look at the latest date at which each entity is modified. Finally, after joining these two datasets, we generate summary statisics and time series plots to understand attribute coverage and data recency.

Currently, we have performed completeness and recency analysis for the following amenities in Kathmandu:
