Locus GIS Pro is a GPS and geographic information system built for people
who work outdoors. It runs where there is no internet: download the map in
advance, keep every measurement on the device, and export to standard GIS
formats when the job is done. No account required — your data never leaves
your phone.
■ OFFLINE MAPS
• Satellite and topographic base maps
• Download the visible screen, an area you draw, or a corridor along a route
• Downloaded regions are outlined on the map, so you know your coverage
• Detail level is independent of how far you zoomed in
• KMZ/KML raster overlays (georeferenced imagery) draw on top of the map
■ PRECISE POSITION
• MGRS, UTM, WGS84 and geographic degrees
• All worldwide UTM zones, plus national grids and your own proj4 definition
• Satellite status: constellation, signal strength, satellites used in the fix
• Position averaging — collect samples on a fixed point to cut the scatter
• Antenna height reduction (phase centre to ground)
■ EXTERNAL GNSS AND RTK
• Connect external receivers over Bluetooth Classic (SPP) or BLE
• NMEA 0183 parsing (GGA, RMC, GSA, GSV, VTG)
• NTRIP client: pull RTCM corrections from a caster and forward them
• Automatic GGA uplink for VRS networks
• Fix quality (single / DGPS / float / fixed), HDOP and satellite count
■ FIELD DATA CAPTURE
• Waypoints with folders, icons, colours, notes and photos
• Your own attribute schema — text, integer, decimal, date, boolean, list
• Routes, track recording, slope routes, ruler measurements, areas and circles
• Freehand sketching and notes on photos
• Stakeout: bearing and distance to target, cut/fill, offset points
• Proximity alerts at a distance you choose
■ GIS FORMATS
• ESRI Shapefile import and export (.shp / .shx / .dbf / .prj / .cpg)
• Multi-layer archives: every shapefile inside becomes its own layer
• Projected files are reprojected to WGS84 automatically
• Polygon holes, multi-part geometry and linked photos are preserved
• Attribute text is UTF-8 — accented and non-Latin names survive the round trip
• KML, KMZ, GPX and CSV
• Attribute table: sort, filter, jump to a record
• Layer styling, value-based colour rules and labels
• WMS / WMTS services — add your organisation's own server
■ BUILT FOR THE FIELD
• Everything stays on the device; no account, no sign-up, no forced cloud
• Back up and restore everything as a single file
• Compass, AR navigation to a target, weather
• Projects keep each job in its own folder and share in one tap
• 30 languages, portrait and landscape
For forestry, cadastre, mining, utility and power line inventory, agriculture,
archaeology, municipal field crews and anyone collecting data outdoors.
