PDA-Based Solution helps build graphical surveys.
August 12, 2008 -
To support floor-plan surveying of facilities, OrthoGraph Survey can manage large data amounts, connect with databases, and support teamwork. Measurements are produced in electronic format, on the spot, using all possible data-entry equipment - on-screen or external keyboard input and laser distance meter - and provides automatic control for values. Each room (logical zone) can have its own drawing, uniquely created by sketching it into PDA and measuring distances.

PDA Based Professional Surveying Solution for Building Surveys
The goal of the new product developed by the company OrthoGraph is the highest achievable support of floor-plan (graphical) surveying of facilities. Using this software the measurements are produced in electronic format right on the spot, while using all possible data-entry equipments and providing automatic control on the values. The system is able to manage large data amounts rapidly, to connect with databases, supports teamwork and - for making the data acquisition easier - can handle laser distance meters or barcode readers (e.g. for inventory purposes).
After specifying the structure of rooms each room (or logical zone) can have its own drawing. This drawing is uniquely created first by sketching in the particular room into the PDA, and after that measuring the distances in order to have the proper floor-plan entered. To keep the sketching process as easy as it is possible the system provides numerous tools like "ghost layer" function that allows the user to show and snap to already sketched or measured zones. Ghost layers are displayed in gray to help the user distinguish them from the room that are about to be drawn. In many cases it may be enough to have the particular rooms sketched and partly measured (that is supported by the "fast measure" function), but in some cases it is required to have them exactly surveyed. Using the automatic measurement functionality the OrthoGraph Survey software warn for each missing measurement one by one, and controls to do all necessary measurements on-site.
For entering distances on-screen or external keyboard can be used, but the best and fastest way is to use a laser distance meter. The model Leica Disto A6 is such a measurement device, which is supported by default, and using the bluetooth connection it transfers the measured distances with one single click. In case of automatic measurement there is an additional feature of this device which means besides the measured distances the Leica device can step back and forth between the measurement steps, so that it controls the whole measurement and the PDA can be used only as a display.
Besides the graphical DWG export format numerous other formats are supported, such as .xls, pdf, .txt, .xml. Using these formats most of the required listings and further processing tasks can be done easily. The integration to other existing systems is also very easy either using these standard file formats or by creating a custom native interface add-on. Such a connection is already available to some CAFM systems like ArchiFM as an example.
