The matter of each information system is set of data contained in the system. In a group of land information systems (LIS) these are the geographical data representing some land fragment in a descriptive and graphical way. The choice of LIS creation method depends on a chosen way of source data acquisition, which defines the following and specific action taken to adapt data for created system's needs. This problem exists, because using different methods we can get data in analog or digital form. Moreover, digital data can be defined as text or graphical data, and graphics can be divided to raster and vector ones. The graphical data in a vector form are the most valuable data in a system, because otherwise we need a lot of complicated - and cost increasing - data processing in order to digitize analog data through raster form to the final vector version. "It is well known, that during LIS creation process (...) the acquisition of (properly prepared) data takes 90% of costs". The analysis of available data acquisition methods' usability will let to justify economically the choice of data acquisition method based on Global Positioning System (GPS).

In this study, a data logging card and software have been designed to be used for various industrial applications. The card was developed by using AT89C52 microcontroller and data logging software was developed by using C#.NET 2005 programming language. The data obtained from the weight sensor has been processed with help of the software prepared and the data logging card. The program produced in this study, can be suggested to be used for industrial data collection operations or as an experiment set in some instrumentations.
