Land Parcel Identification System

Ministry of Agriculture, Forestry and Food of the Republic of Slovenia

Purpose of the project is to establish Graphical Units of Agricultural Land (in Slovene: GERK), which serve as a core for European Union's agricultural subsidies.

Application was developed for Slovenian MAFF. Its main principle is to define location and area of unified piece of agricultural land with the same land use, cultivated by one farmer on the basis of aerial digital orthophoto images of Slovenia. GERK is a web application written in Java programming language allowing more users (collaborators from MAFF, Agricultural Advisory Service, Administrative Units and local Geodetic Services) to work on the same database via internet or intranet. We developed a system of servers and connections that allows several hundred users to use the application online. It allows the user to enter and reshape vector polygons with immediate topology check, entering of attribute data (domestic land name, comments of collaborator and farmer, land use), analysis and manipulation of data, searching GI database, handling and printing final report on meeting. Application uses and manipulates data from several external databases via internet, including the Registry of the Agency for agricultural market and agricultural politics and the Permanent crop and Vineyard registry. Three other applications were developed to complement GERK application. First application allocates farmers to collaborators. This application was necessary because of the great number of farmers (over 70000), that had to be handled in eight month. Application also allows analysis of the work done, by individual collaborators as well as organizations (MAFF, Agricultural Advisory Service, Administrative Units and local Geodetic Services). Second application is called Support Center. It is designed to help collaborators with their work. Third application is GIS web viewer. It is primary designed for farmers to view GIS data: digital cadastral parcels layer, land use layer and entered GERK layer. Application has a free access and is not password protected.
