title CONVERSION OF GPS DATA TO CARTESIAN COORDINATES VIA AN APPLICATION DEVELOPMENT ADAPTED TO A CAD MODELLING SYSTEM
source 2nd International Conference on Experiments/Process/System Modelling/Simulation & Optimization (2nd IC-EpsMsO), Athens, 4-7 July, 2007
summary Nowadays, common methodologies in telegeoprocessing–telegeomonitoring use telecommunication means such as the GPS in order to transmit geographical coordinates to modelling and simulation systems. These 3D geodetic coordinates (φ, λ, h) can be used by modeling systems via specifics interfaces in order to proceed to real-time modelling of the remotely transmitted data. A previous published work describes a real-time remote 3D digitizing and modelling procedure via transmitted Global Positioning System (GPS) data from the field towards to a CAD system. However, these GPS data must be converted to adequate coordinate’s format (x, y, z) so that the CAD system can use them. This paper presents the computing development of a specific application adapted to a CAD modelling system permitting the conversion of the geodetic coordinates to cartesian coordinates. It presents the relation between geodetic and cartesian coordinates, the options of the final developed application and finally some schematic aspects of the computing process. The application development is realized in AutoCAD modelling system environment via special developed interface in Visual Basic (VBA) and Visual Lisp programming language. The aim of this work is to give the possibility to a CAD modelling system to “translate” and receive automatically geographical coordinates or to convert manually and selectively geodetic coordinates φ, λ, h to cartesian coordinates x, y, z.
