A quick first look at any urban area

For students, researchers and planners who need a fast answer before opening a full GIS: what is within walking distance of this point, how has this area changed, and how do two cities compare.

What you can do in a few minutes

Count schools, clinics, parks and transit stops within walking distance of any point, and download the result as GeoJSON or CSV.
Find the nearest facility of a kind and its distance.
See large-scale change in water, vegetation and built-up area in NASA imagery back to 2012.
Read a city's population, area and density with the census year attached.
Measure the length of a corridor or the area of a site by drawing on the map.

Where it fits beside a full GIS

This is a first-look tool. It needs no installation or data preparation, which makes it useful for a quick check, a field visit or teaching. For overlays of your own data, network analysis or cartography, export the points and continue in QGIS or ArcGIS.

Where the data comes from

Places come from OpenStreetMap, population from Wikidata with its census year, weather and air quality from Open-Meteo, and satellite imagery from Esri and NASA. Each figure in the app shows which one it came from.

What it cannot tell you

Analysis uses straight-line distances, not travel time along the street network.
You cannot upload your own layers yet.
Population figures are for whole cities, from the census year shown, not for wards or small areas.
