Methodology for the production and updating of agricultural land use / cover data set
Halil Ibrahim Inan & Ismail Dursun
Within the framework of The European Common Agricultural Policy of the European Union, Agricultural Policy implementation has dramatically changed in the early 1990s with a need of incorporating a vast variety of spatial data and accordingly information systems. Spatial part of these information systems is called as Land Parcel Identification Systems (LPIS). Land use/cover information within these systems is of crucial importance because of the need to monitor farming activities. In Turkey, similar developments and accordingly needs have also been on the agenda since the year 2000. Using cadastre and land registry data, incorporating ortho-photos or imagery and defining physical blocks as land parcel units were three basic alternatives to overcome the problem of both identifying land parcels and assigning their land use/cover information. In addition to the needs of the Ministry of Food, Agriculture and Livestock, emergence of the needs of different institutions (e.g. The Turkish Statistics Institution) has further complicated the properties of required data, especially data on land use/cover information.
