SAS Planet (or SAS.Planet) stands out as a versatile, free navigation program designed to view and download high-resolution satellite imagery and conventional maps from major services like Google Maps, Bing, Yandex, and OpenStreetMap. Unlike standard web-based map viewers, this utility allows you to save huge areas of the globe directly to your local drive for offline access, making it indispensable for users with unreliable internet connections. By consolidating dozens of map sources into a single interface, it simplifies the process of acquiring geospatial data for personal travel or professional analysis.
Key Features
- Multi-Source Map Viewing: Access and switch instantly between over 100 different map services, including satellite layers, political maps, and landscape views, without needing to visit multiple websites.
- Offline Cache & Downloading: Automatically saves every viewed tile to your local disk, allowing you to browse previously visited locations without an internet connection or bulk-download specific areas for field work.
- Advanced Image Export: Stitches downloaded map tiles into a single, seamless file (such as JPEG, ECW, or GeoTIFF) with georeferencing data, ready for immediate import into professional GIS software like QGIS or ArcGIS.
- Portable Operation: Runs entirely without installation from a USB drive or local folder, keeping your Windows registry clean and allowing you to carry your map collection between different computers.
- GPS Integration: Connects directly to a GPS receiver to display your real-time position on the map, track your movement, and log waypoints for reliable navigation in remote areas.
- Measurement & Analysis Tools: Includes built-in utilities to measure distances and calculate precise areas on the map, essential for preliminary site surveys and route planning.
Use Cases
This software is a favorite among GIS specialists and surveyors who need to prepare base maps and raster imagery for remote locations where internet access is non-existent. It also serves outdoor enthusiasts and off-road travelers who require detailed, custom offline maps for navigation on laptops or ruggedized tablets during expeditions.
SAS Planet offers a unique advantage by bypassing the limitations of browser-based viewing, giving you complete ownership and control over your mapping data in a lightweight, portable package.
