ArcGIS / Esri
The dominant municipal GIS stack. It appears here because so many city 'data portals' are in fact an Esri Hub, which shapes what the data looks like and who can read it.
How this list is decided. Membership is not a field an editor set: it is every published entry whose own text names ArcGIS / Esri, matched at build time, with the sentence printed under each row so you can judge the match yourself. 25 entries in 20 cities.
✔ Every published entry is checked against the public sources it cites before publication.
