Geo Data Collector vs eLiteMap

Geo Data Collector turns your iPhone or iPad into an offline-first field GIS for mapping, asset inspection, structured data collection, surveying calculations, and construction layout job preparation. FIELD DATA COLLECTION • Capture points, lines, and polygons with attributes and photos. • Build forms in the app or import shareable JSON form designs. • Mark fields as required or optional and use text, number, date, checkbox, radio-button, and selection controls. • Review, search, edit, delete, and return to collected features on the map. EXTERNAL GNSS, RTK & NTRIP • Connect a compatible Bluetooth GNSS receiver that outputs NMEA 0183. • Stream validated RTCM 3 corrections from NTRIP v1/v2 RTN or CORS casters to the external rover. • Monitor fix type, receiver-reported accuracy, DOP, satellite count, signal quality, correction age, and data freshness. • Apply configurable quality gates, stable-fix checks, and ECEF/ENU point averaging before capture. • Preserve observations, occupations, antenna information, quality decisions, and available coordinate-operation provenance in versioned archives. The external receiver computes the RTK position solution. Achievable accuracy depends on the receiver, antenna, environment, correction service, configuration, and field procedures. SURVEYING & GEODESY TOOLS • Planar COGO inverse and forward calculations. • WGS84 geodesic inverse and direct calculations. • Polygon area, perimeter, orientation, and centroid. • Slope distance, grade, inclination, and elevation difference. • Stakeout deltas, Bowditch traverse adjustment, and angular-closure diagnostics. • WGS84 ECEF/UTM operations, explicit control localization, and auditable geodesy reports. CONSTRUCTION LAYOUT PREPARATION • Create and manage layout jobs and design targets. • Import targets from supported GeoJSON and CSV/ASCII point files. • Configure metric, international-foot, or US-survey-foot units and horizontal/vertical tolerances. • Build a 2D site localization from control pairs and review residual diagnostics. • Export as-built CSV, stake-report JSON, and Markdown field reports. OFFLINE MAPS & OPEN DATA • Work with GeoPackage, GeoJSON, raster MBTiles, and vector MBTiles. • Use online and offline basemaps, including vector, terrain/topographic, hillshade, satellite, and boundary layers where available. • Browse searchable attribute tables and control layer styling, visibility, opacity, and display order. • Convert supported vector formats, including zipped Shapefile, KML, GPX, CSV, and WKT, into app-ready data. FIELD OPERATIONS • Measure distance and area, record GPS tracks, search OpenStreetMap, save spatial bookmarks, and view coordinates in multiple formats. • Use offline field projects, field editing workflows, and geodesy/control reports. • Share files through supported cloud, FTP, WebDAV, and local Wi-Fi workflows. • Connect TAK Server and Meshtastic workflows for team position and messaging. Core collection and offline mapping do not require a proprietary server-side database. Some capabilities require compatible external hardware, network or correction services, imported data, or an in-app purchase. Geo Data Collector is a field mapping and construction aid. It does not replace a licensed surveyor, legal boundary determination, instrument calibration, or required professional quality-control procedures.

eLiteMap is a universal application with an extensive set of tools for full-fledged work with interactive maps offline. It is designed to work with maps in a special mobile format CMF2. To export your maps from other formats to this one, use the desktop application for creating CMF2 files from geodata and geolocated images of territories - eLiteMap Creator. The application is accessible to a wide range of users, regardless of GIS skills, and can be used in various fields, including electrical energy industry, agriculture, geology and geodesy, housing and utility, environmental protection, water and land resources management, ecology and incident management, urban management, etc. eLiteMap app offers a comprehensive set of tools for collecting, processing and analyzing spatial geodata without authorization, payments and in-app purchases. Maps management - Work in the app without authorization, payments and in-app purchases. - Store your maps in a convenient catalog. - Use reliable methods for your maps protection. - Create fully functional projects for work with all the needed information. - Save selected map areas as bookmarks. Working with objects - Create and edit point, line, and polygon features on the map. - Add media attachments (photo, video and documents) to features. - Record voice comments when creating and describing features on the map. - Create points on-the-fly using your device camera. - Create points on the map with a single tap while moving, add description later if needed. - Add graphic marks as text, arrows or free hand graphic. GPS tracks and navigation - Record your GPS tracks and create polygons based on them. - Save tracks automatically without being distracted by editing them as you go. - Use features on the map as landmarks or destination points on your route. - Search and identify features offline. - Measure distances and areas. Data export - Share coordinates of features on the map by sending a file or a link. - Upload maps in MBTILES* formats. - Share collected data in GPKG (GeoPackage), GPX, KML/KMZ and SHP formats. *Maps in MBTILES format with raster tile type only are supported. Take the opportunity to create your own branded application for viewing and working with mobile maps based on eLiteMap for your company.
