The agricultural cadastral maps are of significant important (from engineering and legal reasons). They are the main documents for ownership and land parcels. The cadastral map is approved document by the courts. Therefor resolves the base to disputes of land. This contributes to preserve the property rights of institutions and individuals. In Iraq, the cadastral maps were not given sufficient care and considerations (in term of re-production and updating processes based on modern surveying techniques). So that the cadastral map was a limited usage and they were difficult to be implemented in spatial databases and other related GIS applications. In this study, a number of agricultural cadastral maps were updated. A specified area within the province of Dhi Qar (southern Iraq), the geodetic procedures and processes were implemented. The old geodetic system (Ellipsoid: Clarke 1880, Datum: Nahrwan 1967), and within using geodetic control points on the original agricultural cadastral map, the researcher has identified a number of geodetic control point was identified according to the new coordinate system (Ellipsoid: WGS 84, Datum: ITRF) by using the TOPCON GR5 GPS system in accordance with the static observation mode after then the observed data the second is sent the observation GPS data (as a RINEX file format) via the Internet to the OPUS specialized site for GPS control points correction, this site depends upon the neighbor CORS worldwide global geodetic control points from the observation data), after processing and correction of the sent observation data, the corrected version of the observed data, will be received as a file sent to the user's e-mail. By using the linear transformations between the old geodetic system (Ellipsoid: Clarke 1880, Datum: Nahrwan 1967), and the new geodetic system (Ellipsoid: WGS 84, Datum:ITRF), after then the geometrically corrected cadastral map (in its Raster Mode) preprocessed (editing) under ArcGIS software an0.6 resolution Qu
