    Dear all, I am the developer of the app iTopography, which is available on the appstore.

    Have you ever found yourself in the situation where you need to
    calculate the area of your garden, the living room, a field or even the geometrical shape for a
    class homework?

    iTopography was developed to assist you in calculating the area of any
    surface, and is developed on the premise that a surface can be
    approximated as a polygon of finite number of lines and vertices
    (points). Therefore, iTopography can calculate the area of any surface!

    iTopography uses the GPS device to obtain the longitude and latitude of
    the current position. In the case of a weak signal (e.g., inside the
    house), the user is asked to give the distance between two adjacent points. In
    order for iTopography to compute the area of a surface, the user must
    move along the borders of the surface in a clockwise or
    counter-clockwise direction. When the user inserts the points,
    iTopography will connect the adjacent points with a straight line, draw
    the surface, and calculate the area of the surface along with its
    perimeter.

    Please, pay attention that the accuracy of the program depends on the accuracy of the GPS device. Thus, iTopography should not be used to determine boundaries.

    The webpage is not ready yet, but it will soon be.

    The app costs $0.99 and you may find more info at itune

    Hope you like it. I am looking forward to comments/suggestions.

    Thank you

    A new version (1.2) is submitted to Apple for review.

    Features of version 1.2:

    - The first two points are labelled on the map.
    - On the map, the user can click on the button with the calligraphic letter "i" to read the distance between two adjacent points, and the angle of the vertices.

    You might want to check the spelling of the words in your program, "accuracy" vs "acuracy" for example.

    Thank you. The word accuracy was misspelled in the Settings. If you find another typo, please let me know.

    No problem. I hate it when my fingers don't listen to me, and I incorrectly spell something because of that.

    Dear all,

    Last week I have been working on the code for the GPS device. This code has been rewritten and now the accuracy is 5-10meters (iPhone 4). Therefore, I decided to cancel the submission of version 1.4 (old), and on October 21st I resubmitted the new version 1.4

    Dear all, the version 1.6 is ready for download.

    I believe that all the problems that the users with OS4 were facing are solved.

    New features:
    The user can properly zoom in/out on the map
    The user can rotate the map
    The user can Manually add points by giving the Longitude/Latitude of the point
    Spherical trigonometry is implemented to accurately calculate the angles and distances.

    I am pleased to inform you that version 1.8 is ready for download.
    The main feature of this version is that the user can compute the area of any sub-region on the fly.
    Also, the bug with decimal button is fixed. Finally, the bug that resulted in erroneous calculations when the user had selected "Spherical Coord."-->OFF, "GPS"-->OFF and "Longitude/Latitude"--->OFF is fixed.

    Hi, I just uploaded a video to show how to manually add points to the iTopography app. You may find the video at:

    High Quality
    Low Quality for iPhone

    Hope you find it useful. If you have any questions/comments do not hesitate to contact me.

    Thank you

    Dear all, iTopography version 2.2 is available for download. The main feature of this version is that you can get the coordinates of place by clicking on the Google Map.

    The video shows a brief demonstration of this new feature.

    iTopography version 2.4 is ready for download

    New features:
    - Fixes compatibility issues with iOS 7 and iPhone 5
    - Converts data to WGS84 and ΕΓΣΑ87.

    For the latter feature you need to either enable the GPS or the Longitude/Latitude in the settings. Next, tap on the button to send an email, and the application will convert your points to WGS84 and ΕΓΣΑ87

    As you know, when you enable one of the above two features you can use the Google map to get the coordinates. You bring the Google map up by tapping on the "g" button.
