The "Portable Basemap Server V3-1-zip" is a highly sought-after, lightweight version of this application that allows users to create local map tile servers, enabling offline access to maps from services like Google Maps, OpenStreetMap, and Bing Maps. What is Portable Basemap Server (PBS)?
This dual compatibility is its superpower. Because it adheres to these standards, you can use PBS to create a local, offline service that can be loaded as a basemap directly into applications like ArcGIS Desktop, eliminating the need for a complex and resource-heavy server setup. For instance, one guide demonstrates how to set up a PBS service to use Google Maps imagery directly within ArcGIS, effectively bypassing the need for a paid Google Maps API key for non-commercial use. This makes it an excellent tool for learning, development, and personal projects.
: Supports creating and serving MBTiles and ArcGIS Cache formats, enabling high-performance mapping in environments without internet connectivity.
: PBS fully implements the map tile protocol of Esri's GeoServices REST Specification as well as the OGC WMTS (Web Map Tile Service) standard.
is a lightweight, standalone Windows application designed to bridge the gap between third-party web map tile providers and desktop geographic information system (GIS) software like Esri ArcMap or ArcGIS Pro. The app wraps online map tiles (such as Google Maps, Bing Maps, and OpenStreetMap) into identical Open Geospatial Consortium (OGC) standard Web Map Tile Services (WMTS) or Esri GeoServices REST specifications.
