SW Maps - GIS & Data Collector

Softwel/Aviyaan Tech

About this app

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 or USB Serial.

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 (XLS/ODS) or CSV files.

Ratings and reviews

Flawless, but... :-) when doing Stake Out compass direction seems to point a bit more to the right than what's needed, causing to pass a point then have to come back. compass adjustment or use gps heading combination needed? when using follow gps location, and doing stake out, map jumps around. Cannot zoom in stake out, nice to have if many points close by. Would like option to shift all data according to any point as reference, when using self determined RTK base. eg ReAlign with known pt.

map guality is soo blur and in the photo no date and time show, and the track option is not proper opteion to star stop and take points

mostly great but I use it for photographic geolocation of cemetery headstones. it is annoying that sometimes a camera icon appears in the menu and some times "take photo" is an additional click away. Seems random. additionally, once I take a photo, it would be great if the camera stayed open while it saved the image so that I didn't have to do 3 more clicks and zoom again etc which is a pain when taking 8500 photos.

What’s new

- Fixed photo geotagging
- Direct TCP/IP connection for GNSS corrections
- Added setting for minimum accuracy and maximum age of differential for point recording
- Export start time and number of averaged points in spreadsheet and CSV exports for points
- Feature labels are now shown on the feature list
- Setting to keep display on when app is in use
