About this app

Professional GIS application for offline fieldwork with geodata. It provides data collection, viewing, and inspection with support for connection to external GNSS units achieving centimeter accuracy provided by an NTRIP client. All its features are available above a wide selection of online, offline, and WMS/WMTS maps.

Fieldwork
• Offline collecting and updating of field data
• Saving points with current location, by location averaging, projection, coordinates, and other methods
• Creating lines and polygons by motion recording
• Settings of attributes
• Photos, video/audio, or drawings as attachments
• Setting out of points
• Boundary delineation
• Collecting location data for polygon/line recording or guidance on a target, even when the app is running in the background

Import/Export
• Importing and editing ESRI SHP files
• Exporting data to ESRI SHP or CSV files
• Exporting whole projects to QGIS
• Support of third-party cloud storage (Dropbox, Google Drive and OneDrive)

Maps
• Wide range of maps both for online use and for download
• Support of WMS/WMTS sources
• Support of offline maps in MBTiles, SQLite, MapsForge formats, and custom OpenStreetMap data or map themes

Tools and Features
• Measuring distances and areas
• Searching and filtering of data in the attribute table
• Style editing and text labels
• Conditional styling - layer-based unified style or rule-based styling dependent on an attribute value
• Organizing data into layers and projects
• Templates for fast establishing of a project, its layers, and attributes
• Support for over 4200 global and local CRS (e.g. WGS84, ETRS89 Web Mercator, UTM...)

Advanced GNSS Support
• Support for external GNSS receivers for highly precise data collection (Trimble, Emlid, Stonex, ArduSimple, South, TokNav...) and other devices supporting Bluetooth and USB connection
• Skyplot
• NTRIP Client and RTK correction
• GNSS manager for managing receivers, and set up of pole height and antenna phase center
• Accuracy control - setup of minimum tolerance to collect valid data

Form Field Types
• Automatic point numbering
• Text/number
• Date and time
• Checkbox (yes/no)
• Ddrop-down selection with predefined values
• GNSS data (number of satellites, HDOP, PDOP, VDOP, accuracy HRMS, VRMS)
• Attachments: photo, video, audio, file, sketches, map screenshots

Locus GIS is successfully used in a wide range of industries:

Ratings and reviews

At this point a 4. Works on Blackview BV9800 Pro. The interface is good with good dialogue boxes. I've not tried it in the field yet, and am comparing it to GPS Status as a targeting system - navigate to a co-ordinate. One feature that is an issue is 'point addition', where the input is numeric only - you can not have an alpha in your point such as 'ABC-123', or 123-ABC. Other than this it seems quite slick.

One of the best application for small firms and GIS students or enthusiasts, what you get for the price is outstanding and stability is on a level of the huge GIS software creators like ESRI, it only misses some lil simple things that would make it the best out there, and I am sure the creators are working on that and we would have them in the near future. Good job and keep it up!!

An excellent tool for any sort of field work which requires recording spatial data. Very easy to use and very powerful. Points, Lines and Shapes can be added in separate layers on top of your chosen base map in a variety of colours and styles. It is possible to define a list of attributes (like a form) for the individual points/lines/shapes within each layer. This allows the user to record a whole host of user-defined data about each spatial location as well as attaching multiple photos, videos and sketches to each point. Import/Export tools to external GIS programs allow the data to the consolidated and manipulated centrally. The free version comes with full functionality but with a limit of 2 map layers and 3 data layers, whereas the subscription version removes the limit on the number of layers.

What’s new

The latest version brings direct support for the Toknav P8 device, including tilt‑measurement functionality, and introduces a redesigned export interface with a much simpler project‑sharing workflow. In addition, the update adds support for the reference coordinate system EPSG:8353 and includes a new NMEA manager that streamlines recording and exporting raw NMEA data.
