Mobile Topographer Free for Android

Quick summary

Mobile Topographer Free is a no-cost, precision-focused app for surveyors and landowners who need accurate GPS-derived coordinates. It provides tools to improve positioning accuracy, convert between coordinate systems, and manage point data for measurement, mapping, and export.

Precision and calibration tools

• Convert between GPS geodetic coordinates and Cartesian East–North values, with support for UTM and various national coordinate systems.
• Apply weighted averaging to improve raw GPS positions over time.
• Calibrate maps and adjust device-based positions using known control points.

Mapping, navigation and signal features

• Use the "Drive Me" navigation pointer to guide you to a destination entered as coordinates.
• View satellite imagery overlays, and project single or multiple points into other mapping apps for routing or visualization.
• Rely on auto-stop positioning for stable fixes and inspect per-constellation GNSS signal strength indicators.

Measurements, units and export options

• Calculate areas and save lists of surveyed points for later use.
• Work in meters, international feet, or US survey feet; perform height computations and switch between geodetic and Cartesian formats using either measured or manually entered points.
• Export point lists to a variety of file types, for example: .dxf, .gpx, .kml, .csv, and .txt.

Data input and workflow

The app accepts coordinates from the device’s GNSS receiver or from manual entry, and lets you convert, store, and reproject points as needed. You can maintain multiple point lists and export them for CAD, GIS, or general use.

Limitations and stability

This application has not received recent updates. Because of that, users may encounter occasional crashes, performance slowdowns, or bugs. Consider this when planning critical tasks or relying on the app for mission-critical surveying.

Who will benefit

Survey professionals and property owners who need an inexpensive way to capture and convert coordinates, measure area, and export point data will find this app useful—provided they accept the possibility of stability issues due to its lack of recent maintenance.
