About

Eos Tools Pro

This utility app provides advanced GNSS information for high-precision receivers, crucial for GIS and surveying. It includes an NTRIP client for corrections, user-configurable alarms, and background operation with mapping software.

Highlights
  • Advanced GNSS information (RMS, PDOP, differential status)
  • Built-in NTRIP client for RTK/DGNSS corrections
  • User-configurable audible alarms
  • Background operation with mapping software
  • Satellite view for multiple constellations
  • Orthometric Height and Position Shift computation

Eos Tools Pro is a monitoring utility for the Arrow and Skadi series high precision GNSS receivers from Eos Positioning Systems. It provides advanced GNSS information such as RMS values, PDOP, differential status, satellites tracked and used, that are critical for submeter and centimeter GIS and surveying data collection. The app features a built-in end trip client to access RTK or DGNSS corrections from an RTK network. Eos Tools Pro also allows audible user configurable alarms and runs in the background of your mapping surveying software. Features: - Built-in NTRIP client to connect to an RTK Network - Displays GNSS and Tilt Compensation accuracy with quality control information - Select the Skadi Smart Handle mode: Extensible Virtual Range Pole™ or Invisible Range Pole™ - Satellite view for all constellations in use (GPS, GLONASS, BeiDou, QZSS and IRNSS) - User configurable alarms - Orthometric Height (Geoid models for vertical datum) - Compute and apply Position Shifts to accommodate different - Laser Offset Mapping for Esri ArcGIS® Field Maps - Locate and map underground utility assets directly in ArcGIS Field Maps - Terminal emulator to send configuration commands to the receiver - HTML5 built-in browser Disclaimer: "Continued use of Eos Tools Pro running in the background and connected to the GPS/GNSS receiver can dramatically decrease the battery life of your Apple device."

About

Geo Data Collector

Features
Read full description

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.

Verdict

The call

The clearest difference is in-app purchases: Eos Tools Pro at none against Geo Data Collector's 1. Geo Data Collector's advantage is update cadence (fortnightly vs every 2 months). On price, ads, device support and iOS requirement there is nothing between them.
