SW Maps vs GeoLibre

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).

GeoLibre is a lightweight, cloud-native GIS platform for visualizing, exploring, and analyzing geospatial data. It runs in the web browser, on the desktop, on mobile, and inside Jupyter notebooks. MAPS AND DATA • Add data from GeoJSON, Shapefile, GeoParquet, KML/KMZ, CSV, PMTiles, COG, and more • Connect to tile services, WMS/WMTS, and ArcGIS services • Browse open cloud catalogs including Microsoft Planetary Computer and Google Earth Engine • Beautiful vector basemaps, satellite imagery, and a true 3D globe BEYOND EARTH Planetary basemaps cover the Moon, Mars, Mercury, Venus, the Galilean moons, Titan, Pluto, and Charon, each with the correct ellipsoid, so distance and area measurements match the body you are mapping. ANALYSIS ON DEVICE • Vector tools: buffer, clip, dissolve, intersect, spatial joins, and more • Geoprocessing tools: Run 1000+ free and open-source tools in the browser engine • Statistics and charts driven by your attribute data STYLING AND 3D • Full cartographic control with graduated and categorized symbology, labels, expressions, and legends • Extrude buildings, render point clouds and 3D tiles, and animate time-series data with the Time Slider IN THE FIELD Capture GPS points with photos and attributes using Field Collection, or record GPS tracks as you move. Location is used only while the app is open. There is no background tracking. SHARE AND COLLABORATE Build story maps, print layouts, and dashboards. Invite others into a live collaboration session by sharing a private session code. OPEN AND EXTENSIBLE GeoLibre is MIT-licensed and built on MapLibre GL JS, DuckDB, and deck.gl. The same workspace runs on iPhone and iPad, on the desktop, in your browser, and inside Jupyter notebooks. Extend it with plugins. PRIVACY GeoLibre does not require an account and collects no analytics. Optional online features such as basemaps, place search, the AI assistant, cloud catalogs, and live collaboration send requests directly to those services when you choose to use them.
