SW Maps - GIS & Data Collector

Collect, manage, and share geographic data with a professional GIS and mobile mapping application designed for surveyors, field researchers, and location-based data professionals.

SW Maps combines the precision of enterprise GIS tools with the portability of your Android device. Whether you're conducting high-accuracy GNSS surveys with external RTK receivers, gathering location data across large areas, or simply viewing and analyzing shapefiles in the field, this free app delivers the functionality you need without subscription fees or advertisements.

Capture geographic features with complete flexibility. Record points, lines, and polygons directly on the map, then attach rich attribute data to each feature—text fields, numeric values, dropdown selections, photos, audio recordings, and videos. This makes it easy to document field conditions comprehensively and maintain structured datasets that match your project requirements.

Advanced surveying capabilities set this app apart. Connect external RTK-capable GPS receivers via Bluetooth or USB Serial for centimeter-level accuracy when precision matters most. Record raw data from external receivers for post-processing workflows, or use your phone's built-in GPS for standard surveys and exploratory work. Measure distances and areas on the fly, and stake out predetermined points and lines on the ground using high-accuracy GNSS positioning.

Work with industry-standard data formats and multiple base layers. Choose between Google Maps or OpenStreetMap as your background, add MBTiles and KML overlays, and import shapefile layers with attribute-based styling from any coordinate system supported by PROJ.4. Stack multiple online WMTS, TMS, XYZ, or WMS layers, and cache tiles locally for offline operation when connectivity isn't available.

Streamline repetitive projects through templates and layer reuse. Create templates from previous surveys and share them with team members, eliminating the need to reconfigure attributes and layers from scratch. Import feature definitions from existing projects or shared templates to accelerate new work.

Export and share your collected data in formats that work with your team's existing tools. Generate KMZ files with embedded photographs, shapefiles, GeoJSON, GeoPackages, spreadsheets (XLS/ODS), or CSV exports. Share complete projects or templates directly with other users, enabling true collaboration across field teams and back-office analysts.

SW Maps - GIS & Data Collector is built to work without barriers—no ads, no paywalls, no forced subscriptions. Download the app today and bring professional GIS capabilities to your mobile surveying and data collection workflow.
