SW Maps vs LiteSurvey Pro

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 -Online Base maps: Apple Maps or Open Street Map -Support for multiple mbtiles and KML overlays -Shapefile and Geopackage layers, with attribute categorized styling. View shapefiles in any coordinate system supported by the PROJ.4 library. -Add multiple online WMTS, TMS, XYZ or WMS layers and cache tiles for offline use. -Connect to external GPS receivers using Bluetooth for high accuracy surveying using RTK with built-in NTRIP client. Also record data from external receiver for post processing. -Define multiple number of feature layers, each with a set of custom attributes Feature Types: Point, Line, Polygon Attribute Types:Text, Numeric, Drop down Options, Photos, Audio, Video Save as Template for re-use or sharing -Record GPS tracks, with distance measurement -Label features based on attribute values. -Import feature layers from templates or existing projects. -Share or export collected data as KMZ (with embedded photographs) , shapefiles, GeoJSON, Geopackage (GPKG), XLS/ODS spreadsheets or csv files. -Share templates or projects with other users -Supports use of GTX geoid files. To use custom geoids, prepare a GTX file with offsets in meters from WGS84. This product is made in Nepal and is FREE (no Ads).

LiteSurvey Pro: Professional GNSS Surveying on iPhone and iPad LiteSurvey Pro is a field data collection app designed for use with compatible LiteSurvey GNSS receivers. It combines real-time RTK positioning, map-based GIS data capture, advanced measurement tools, and project management in a clean, modern interface optimized for iPhone and iPad. KEY FEATURES RTK GNSS POSITIONING Connect a compatible LiteSurvey GNSS receiver through supported MFi connectivity. Configure NTRIP correction services, monitor positioning solution and correction status, and support centimeter-level RTK workflows under suitable conditions. Accuracy depends on receiver hardware, correction data, satellite visibility, and the operating environment. MAP-BASED DATA COLLECTION Create and edit points, polylines, and polygons. Organize work in layers and use customizable attributes, notes, and photo attachments to build structured field datasets. ADVANCED MEASUREMENT On supported receiver models, use tilt compensation and laser ranging to capture points efficiently, including targets that are difficult to reach. Availability depends on the connected receiver and its capabilities. AR-ASSISTED PHOTO MEASUREMENT On compatible LiDAR-equipped iPhone or iPad models, connect a supported LiteSurvey GNSS receiver and use the required mounting hardware to perform AR-assisted photo measurements. Availability depends on the Apple device, receiver model, and accessories. COORDINATE SYSTEMS Use broad EPSG-based coordinate-system and transformation support for field projects, including supported geoid models, coordinate display formats, and measurement units. RECORDING AND EXPORT Export layer data as CSV and recorded tracks as GPX or KML. Record RTCM3 data and convert supported recordings to RINEX observation and navigation files for post-processing workflows. PROJECT MANAGEMENT Manage projects, layers, attributes, photos, tracks, and receiver files. Review collected features and share or export selected data when needed. HARDWARE AND COMPATIBILITY Some functions require a compatible LiteSurvey GNSS receiver, supported receiver capabilities, a LiDAR-equipped Apple device, or a dedicated mount. Feature availability varies by device and hardware. LiteSurvey Pro helps field professionals collect and manage precise GNSS and GIS data with a streamlined iPhone and iPad workflow.
