Topography vs topoXpress
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Topography
This tool helps civil engineers, architects, and surveyors measure surface areas and convert coordinates. It allows users to calculate polygon areas, convert coordinates to UTM EGSA87 Datum, and export measurements in DXF, KML, or TXT formats via email.
- Convert coordinates to UTM EGSA87 Datum
- Calculate polygon area in square meters
- Export measurements in DXF format
- Export measurements in KML format
- Export measurements in TXT format
- Input coordinates manually

The application is very useful to Civil Engineers, Architects, Surveyors, and those interested in measuring a surface area or converting its coordinates to UTM EGSA87. This tool enables users to: 1. Convert the coordinates (x,y) to UTM EGSA87 Datum 2. Calculate the area of a polygon in square meters (m2) 3. Send the above measurements by e-mail in [dxf] file format. The dxf file can be opened in a MAC or a PC by any drawing application like Autocad. 4. Send measurements by e-mail in [kml] file format. The kml file can be opened in a MAC or a PC or iPhone by GoogleEarth application. 5. Send measurements by e-mail in [TXT] file format. The text file contains coordinates either in EGSA87 Datum or Latitude and Longitude in decimal degrees or UTM coordinates. The measurements mentioned above can be provided not only by placing the iPhone in each border of a surface area, but also from distance (when users are on their bed or their sofa). Users may also have their final measurements by entering the coordinates either in EGSA87 Datum or Latitude and Longitude in decimal degrees.

topoXpress provides the following features: • Multiplatform design: the same software with the same rich functionality for both GIS data collectors and Surveyors on iOS & macOS. • Handling and displaying large spatial datasets (raster and vector). • Responsive and intuitive user interface: easy to learn and use, automatic adjustment to different screen sizes, orientations, and resolutions of mobile (iPhone, iPad) and desktop devices. • Online and offline operation: online data sources (Cloud storage, TMS, WMS, KML), offline raster datasets (jpeg, ecw, ers, tiff, png, lan, bil, ENVI bsq), offline vector datasets (shp, dxf, map, GeoJSON, mif, txt, crd, dat, dbf, tab, mid). • Powerful GIS visualization functions: thematic mapping, transparency, labeling, query, layer groups, vector symbols, line types, fill types, event mapping. • Productive data collection: templates, surveying, stakeout, CoGo (Coordinate Geometry), forms, lists, calculated fields, GIS editing functions, sampling tool, and more. • Collaborative mapping for professional users through the topoXpress cloud service. • Extensive support of GNSS receivers through TCP port & Bluetooth, projection systems, geoids, shift grids. Bluetooth Rangefinder support for CoGo tasks. The app can be used in many different sectors: • Field data collection and inspection • Land Surveying • Topographic mapping • Forestry • Farm mapping • Utility mapping and inspection • Archeology *** NOTE: topoXpress offers all specified GIS functions free of charge. However, loading more than 10.000 records, saving and exporting your job can be done through our cloud service.
