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.

Highlights
  • 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.

Bring your GIS workflow to the field. Global Mapper Mobile® is a powerful iOS application for viewing and collecting GIS data. It utilizes the GPS capabilities of mobile devices to provide situational awareness and locational intelligence for remote mapping projects. A perfect complement to the desktop version of Global Mapper, the mobile app provides maps-in-hand functionality for engineers, surveyors, wildlife managers, foresters, and anyone whose job requires access to spatial data in remote locations. Global Mapper Mobile can display vector, raster, and elevation data layers that have been transferred from the desktop version of the software. It also provides tools for drawing, tracking, and form-based data collection using pre-configured attributes and picklists. Global Mapper Mobile Base Version (Free) The base version of Global Mapper Mobile is free of charge and provides an array of features and functions, including: • Vector, raster, and terrain data display • GPS location display • Point, line, and polygon feature creation using GPS location • Editing of existing vector features • Capture of images in the field • Creation of Picture Points from geotagged images • Attribute and feature notation recording for new or existing vector features • Online access to Open Street Map data Global Mapper Mobile Pro The Pro version of Global Mapper Mobile, available as an in-app purchase, supplements the functionality of the base version with an array of professional-grade tools, including: • Advanced GPS support for connection to high-accuracy GNSS devices from vendors such as Bad Elf, EOS, Juniper, and others • RTK correction via built-in NTRIP client • GPS Averaging • Terrain shader and water level display options • Custom online source options and online data saving for offline use • Simultaneous feature creation • Viewshed creation • Volume calculation • Data reprojection • Address searching • Geopackage and GeoPDF format support Global Mapper Mobile Pro is available as an in-app purchase. The license is based on an annual subscription from the date of purchase that can be renewed each year. Note: Continued use of GPS running in the background can dramatically decrease battery life.
