The types of photographs and images that can be processed, georeferenced include satellite, aerial, terrestrial, close-range, and oblique. The use of the satellite-acquired data for environment resource study is part of an interdisciplinary field in which soil science is combined with remote sensing and information technology. Panchromatic satellite image,  1:50.000 scale cadastre map, 1:25.000 scale cadastre map, 1:10.000 cadastre plan; the cadastre situation in the studied area necessary to create a database; pedologic data from the researched area and climate data from the researched area; specialised software for working with image files or image viewing: Autodesk Map 5, WinGis, Erdas Imagine 8.3.1., ACDSee 5, Volo View Express. The system can be applied in the agricultural decision-making process and environment resource management. Single frame orthorectification techniques orthorectify one image at a time using a technique known as space resection. In this respect, a minimum of three GCPs is required for each image. However, precision application like those for plots, must be used with great care. The main difficulty at the national level is the lack of a numerical field pattern of a resolution compatible with the satellite images and a team of experts in correcting the atmospheric effects on satellite data. The integration of an archive on paper in an intelligent modelling system requires the conversion of the raster format in a vector – vectorization. Regarding the precision in delimiting the soil units for drawing soil or erosion maps, an accurate topographic base (topographic maps and cadastre plans) and airborne photograms or satellite images are required. The vectorization process is the best solution the CAD/GIS users need for a conversion to a smart database.
