SW Maps1.4.1 - App Store

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 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.

Record points, lines, polygons and even photos and have them displayed over 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.

Conduct high accuracy GPS surveys using external RTK capable receivers over Bluetooth LE.

Draw 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 Geopackages, KMZ or shapefiles, or export them to your device storage. Also share and export recorded data as Spreadsheets or CSV files.

All data is recorded and exported in the standard WGS84 Geographic coordinate system (EPSG:4326).

Features
