SW Maps is a free GIS and mobile mapping app for collecting, presenting and sharing geographic information.
Whether you are conducting a full-scale GNSS survey with high precision instruments, need to collect a large amount of location-based data using nothing but your phone, or just need to view a few shapefiles with labels over a background map on the go, SW Maps has it all covered.
SW Maps can record points, lines, polygons and even photos and have them displayed in your choice of background map, and attach custom attribute data to any feature. Attribute types include text, numbers, an option from a predefined set of choices, photos, audio clips and videos.
It conducts high accuracy GPS surveys using external RTK capable receivers over Bluetooth.
It draws features on the map by adding markers and measure distance and area.
Reuse the layers and attributes of a previous project for another survey, or create templates and share them with other users.
Share the collected data with other users as KMZ or shapefiles, or export them to your device storage.
