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. ## Key features - 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 ## Recent user reviews (10 of 58) All indexed reviews: https://appshunter.io/ios/app/topography/id622591557/reviews.md ### 2/5 — OK but clunky *2025-04-10, version 4.8* Say you want to check a topographic plan for a property. You have to enter the coordinates one by one and if you make a mistake as far as I can see you can’t go back and edit a pin. This ability would be a huge improvement. ### 1/5 — Δεν κάνει τα βασικά *2025-02-17, version 4.8* Δεν μπορείς να κάνεις μια απλή διόρθωση ενός σημείου. Δεν έχει ζουμ για να διορθώσεις ένα σημείο. Τζάμπα τα 3€ ### 1/5 — NOT GOOD RESULT *2024-11-11, version 4.8* Unfortunately there is no good result...u prees the pin button and doesn't understand that... ### 1/5 — Απογοητευση *2024-05-08, version 4.8* Δεν βλέπω τροπο να αποθηκεύω μια αποτύπωση ούτε να εξάγω σε dxf . Το Κουμπί της επεξεργασίας δεν δουλεύει ### 3/5 — Useful app but needs more functionality *2024-02-03, version 4.8* There is no way to import saved multi point co-ordinates. Once you change the coordinate system all the data is lost so unless you have sent them to your email before everything is lost! ### 1/5 — Crap *2023-09-30* There is £2.99 il not see again , I’m a civil engineer, this looks like it was designed by a clown no star rating ### 1/5 — Άκυρη *2023-05-12, version 4.8* Τζάμπα λεφτά δεν δούλεψε σωστά ποτέ ### 1/5 — Too buggy *2022-12-27, version 4.8* This is amateur work. There are many bugs and inconsistencies in the UX flow of mapping a plot that bear this app unusable. I don’t recommend. ### 5/5 — Πολύ καλή δουλειά !! *2022-10-16, version 4.8* Καλησπερα, για αρχή η εφαρμογή είναι εξαιρετική. Αυτό που απουσιάζει και με ανάγκασε να επικοινωνήσω από το πεδίο με συνεργάτη στο γραφείο, ειναι η μοίρες όπου θα μπορούσε με μια επιλογή χρήσης (on/off) αλλά και επιλογή μερικών χρωμάτων όπως κοκκινο,πορτοκαλί ή σκούρο γκρι (ανάλογα το χρωματικό πεδίο του σημείου όπου δουλεύουμε) για να είναι ευδιάκριτο. Στην καρτέλα manual ειδικότερα καθώς ηδη υπάρχει το σταυρόνημα και δηλώνει ξεκαθαρα Βορρά Ανατολή νότο και Δύση (πάντα με βορινή ένδειξη στην πυξίδα) Θα ήταν τρομερά καλό για όσους δουλεύουμε με αζιμουθιο σε πυκνή βλάστηση κλπ με μηδαμηνή ορατότητα 2 σημείων μεταξύ τους. Το σταυρόνημα παραμένει με επιλογή για τον χρήστη προσθήκης η όχι μοιρών πάνω στο σταυρόνημα (πάντα με την πυξίδα στον βορρά υπενθυμίζω) Ως απλό σχέδιο και βοήθεια σχεδιαστικού τύπου και ΟΧΙ ως λειτουργική πυξίδα.! Ευχαριστώ και πάλι για την Καλη δουλειά που έκανες με την συγκεκριμένη εφαρμογη! ### 3/5 — Υποστήριξη *2022-02-21, version 4.8* Μόλις αγόρασα την εφαρμογή, δεν την έχω χρησιμοποιήσει ακόμη… Υπάρχει κάποιο εγχειρίδιο χρήσης ή άλλο βοήθημα; Ευχαριστώ ## Frequently asked questions about Topography ### What is Topography used for?
