The agricultural territory, delimited and represented by the farthest "cartographic series", is considered to be a "real challenge" in terms of identification and "spatialization" given its spatio-temporal dynamics. Changing the destination of agricultural land and resizing parcels implies the instability of topo-cadastral boundaries, making old mapping materials used in the land use analysis non-permanent. If in the first complex cartographic representations, 100-150 years ago were delimited agricultural fields with different surfaces and destinations, the current situation is very different. Based on this rationale, the present study aims at updating the topo-cadastral databases and materials referring explicitly to the surfaces used as meadows and grassland at the level of Arad county through methods and techniques specific to CAD and GIS environment. It follows the degree of scientific "safety" provided by the old cartographic representations, as well as the possibility of using other current cartographic materials to complement and validate the extracted information so as to create a more accurate picture of the reality on the ground. Following the analysis of the old topographical and cadastral maps and the current mapping materials, significant differences were found regarding the area and the position of the meadows, which alters their share in the total agricultural area. Old cadastral and topographic maps can provide general information about existing grassland at county level, but can no longer be a "safe source" of information. Following the identification of grasslands, their representation and analysis together with other geospatial data sets can be made.
