SPECS at a Glance


My ΚΤΗΜΑ is a computer program running in tablets with ANDROID operating systems. It is effective in map validation – editing and field data collection for Cadastral applications for the following reasons:

    • Displays vector data (DXF format) and raster files (photomaps, 1:50000, 1:5000).
    • On-off continuous display of photomaps and vectors.
    • You can use it for on/offline navigation with layers of the industry leaders OpenStreetMap.
    • GPS tracks recording in SERVICE mode combined with geo-coded/oriented photos.
    • Collects field data in the form of polygons, lines, points, and text with tapping and comment tagging. You can use this data for map validation and field checks. (Vector data for forestry, and topographic applications, DXF interface.)
    • It takes and manages geo-referenced pictures with tagged messages, which indicate the location of the exposure in the GPS tracks.
    •  It will upload and download to Facebook, Internet, Google Maps**, and Autocad.
    • It offers field check trip, index creation and track viewing.
    • Input data for online use: geo referenced maps and images from Google Maps**, and Web Map Service (WMS). You can download, use, process and store the data for future use.
    • Offline data: road maps from OpenStreetMap or photomaps are used. In the case of photomaps, the files are processed in advance using program Cut Map Tiles, Land Data’s Mbtiles format generator [1]. The result is generation of tiles (256 X 256) pixels, facilitating fast zoom and pan of tablets and smart phones.
    • It is observing specs according to EKXA  S.A
    • Application running in an Industry standard tablet (ANDROID** ver. 4.1.2) and
    • more



    The process of making Cadastral maps involves field measurements, processing of aerial or satellite imagery and map validation through quality field checks. You can use MY KTHMA for the map validation and more. First, it guides you to specify areas in the field with the help of the GPS receiver built into the tablet*. The GPS tracks, and the cursor, position locator, are superimposed on the country’s road map and therefore make the online and offline navigation easy.

    You can do the map validation and field checks effectively and economically with transferring from the office all the vectors, points, text (with their colors) into the tablet. As a result you have the office data on to the field, where editing (addition and deletion) of selected features is taking place.

    The new info comes back to the office where it takes its final form, or you can send it from the field,   through 3G (optional) connections, to eliminate any error and omission possibilities, before the operator returns to the base.


    The tablet is equipped with powerful validation – editing – data collection software, using normal editing techniques, or rough editing moves by taping the points of interest and bypassing the use of the cursor. This generates polygons, lines, and points tagged onto features with comments, to expedite the field trips. Quick pan and zoom capabilities assist the editing, for both vector and ortho-images. At the same time there is continuous on, off display of vectors and or photomaps during the editing without stopping the process and keeping the other info active.

    To this, add:

    • Online, offline navigation capabilities using road maps layers from the industry leaders OpenStreetMap, with .map input.
    • Additional software to process large volume of raster images with mbtiles format for fast zoom and pan.
    • The ability to process and store GPS tracks in service mode together with geo referenced oriented photos. These data you can upload and download to Facebook, Internet, Google Maps ** and Autocad, all installed into an industry standard ANDROID** based tablet
    • Web Map Service (WMS). These data can be processed, and stored for further offline use via mbtiles format.


    The tablet* is equipped with data collection software, by tapping the points of interest and bypassing the use of the cursor to expedite the field trips. This generates polygons, lines, and points tagged onto features with comments. You can   display these features with colors of your choice, and you can edit or delete them.


    To use the tablet effectively for data collection or verification-validation you must utilize a layer of Google or street maps in order to locate or identify your lines on the ground. Thus, you are using the displayed Image rather than the positional capacity of the tablet’s GPS unit, which cannot compete against the high accuracy GPS units. Therefore, your positional accuracy depends on the resolution of your image, and particularly on the pixel size.

    In addition, the tablet has the ability to download online data, (geo-referenced maps, and images from Google maps and Web Map Service (WMS). These data can be processed, and stored for further Offline use via mbtiles format.

    ΜY KTHMA can be used effectively for Cadastral and a variety of other disciplines that require general purpose, quick, simple, effective and low cost data collection/validation.

    It is a valuable tablet based software for Cadastral Applications, equipped with manuals for its installation use and, and supported by a team of professionals with long experience in system development and data manipulation.
