Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Topography Lite
This tool helps civil engineers, architects, and surveyors measure surface areas and convert coordinates to UTM EGSA87. It allows users to calculate polygon areas, export measurements in DXF, KML, and TXT formats, and input coordinates manually or by selecting points on a map.
- Convert coordinates to UTM EGSA87
- Calculate polygon area in square meters
- Export measurements in DXF, KML, TXT
- Input coordinates manually
- Select points on map for measurement

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. *********Caution: The Free Version of the program has the additional alteration of EGSA87 coordination by 20% and reduce the measured points. For accurate results buy the full version ! ---------------------------------------------------------------------------------- Η εφαρμογή είναι πολύ χρήσιμη για Πολιτικούς Μηχανικούς , Αρχιτέκτονες , τοπογράφους , και σε όσους ενδιαφέρονται για τη μέτρηση μιας επιφάνειας (γεωτεμαχίου, οικοπέδου κτλ) ή για την μετατροπή των συντεταγμένων της σε UTM ΕΓΣΑ87. Αυτή η εφαρμογή επιτρέπει στους χρήστες να : 1. Να μετατρέψουν τις συντεταγμένες ( x , y ) στο UTM ΕΓΣΑ87 Datum 2. Να υπολογίσουν το εμβαδόν ενός πολυγώνου σε τετραγωνικά μέτρα (m2) 3. Να στείλουν τις παραπάνω μετρήσεις μέσω e-mail σε μορφή αρχείου [dxf]. Το αρχείο DXF μπορεί να ανοίξει σε MAC ή PC από οποιαδήποτε cad εφαρμογή όπως το Autocad. 4. Να στείλουν τις παραπάνω μετρήσεις μέσω σε e-mail σε μορφή αρχείου [ΚΜL]. Το αρχείο KML μπορεί να ανοίξει σε MAC ή PC ή στο iPhone από την εφαρμογή GoogleEarth. Οι μετρήσεις που αναφέρονται παραπάνω μπορεί να προέρχονται όχι μόνο από τη τοποθέτηση του iPhone σε κάθε κορυφή της επιφάνειας που θέλουμε να μετρήσουμε, αλλά και από απόσταση, βρίσκοντας την επιφάνεια που μας ενδιαφέρει από τον χάρτη της εφαρμογής μας και επιλέγοντας τις κορυφές της. Οι χρήστες μπορούν επίσης να έχουν τελικές μετρήσεις τους, εισάγοντας τις συντεταγμένες είτε σε ΕΓΣΑ87 Datum ή το γεωγραφικό πλάτος και το γεωγραφικό μήκος σε δεκαδικούς βαθμούς *********Προσοχή: Η Free Version του προγράμματος έχει επιπρόσθετη αλλoίωση των συντεραγμένων ΕΓΣΑ87 κατα 20% καθώς και περιορισμό μετρούμενων σημείων.

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. Please visit our website for further details: https://topoXpress.com **NOTE ON BATTERY USAGE: The app may dramatically decrease battery life during the use with large spatial datasets. The app supports optional background location services, which can may cause a faster battery drain than usual.
