ANALIZA USPOSTAVE INFORMACIONOG SISTEMA ZEMLJIŠNIH PARCELA – LPIS (Land Parcel Identification System) UPOTREBOM DALJINSKE DETEKCIJE I OBJEKTNO ORIJENTISANE KLASIFIKACIJE SATELITSKIH SNIMAKA (original) (raw)

Abstract

Informacioni sistem zemljišnih parcela (LPIS) i kontrola daljinskom detekcijom igraju važnu ulogu u sistemu direktnih isplata za potrebe poljoprivrede u zemljama članicama Evropske Unije (EU). EU odobrava subvencijе poljoprivrednicima koji uzgajaju određene vrste biljnih kultura. S ciljem upravljanja i kontrole zahteva, EU je donela odluku da osnuje Integrisani Sistem Administracije i Kontrole-Integrated Administration and Control System (IACS), 1992. godine. Tokom godina, otkriveno je da površine za koje se zahteva subvencija često ne reprezentuju realnost. Shodno tome, trebalo je unaprediti proces deklaracije uspostavljanjem Informacionog sistema zemljišnih parcela-Land Parcel Identification System (LPIS), po mogućnosti zasnovanog na ortofoto snimcima. LPIS sistem je ključna komponenta IACS sistema. Takođe je jedan od najkompleksnijih IACS podsistema, posebno zbog grafičke prirode podataka i raznovrsnosti tipova podataka koji su prisutni. U radu je diskutovana je upotrebljivost najčešće korišćenih komercijalnih satelitskih sitema, na osnovu principa daljinske detekcije i tehnike objektno orijentisane klasifikacije upotrebom Erdas softverskog okruženja. Analizirane su prednosti automatske klasifikacije pri izradi jednog ovako kompleksnog sistema. Specificirani su aspekti primene i dat je predlog implementacije LPIS u našem okruženju. Procesiranjem satelitskih snimaka pilot područja okoline Pančeva, upotrebom Erdas programskog paketa analizirani su mogući pristupi u kreiranju i uspostavljanju Informacionog sistema zemljišnih parcela.

ABSTRACT: Land Parcel Identification System and Control with Remote Sensing (CwRS) play an important role in the system of the direct agricultural area-based payments in the EU Member States. The European Union (EU) grants financial aid to farmers, growing a certain kind of crops. In order to administrate and to control the farmer's declarations, the EU decided to establish an Integrated Administration and Control System (IACS) in 1992. Over the years it was found, that the declared areas often do not represent the reality. As a result, the process of declaration should be improved by the establishment of a Land Parcel Identification System (LPIS), preferably based on orthophotos. The LPIS system is the key component of an IACS. It is also possibly one of the most complex IACS subsystems , mostly due to the graphical nature of the data and the variety of different data formats involved. In order to create a pilot LPIS sistem the usefulness of the most common commercial highresolution satellite systems is discussed based on remote sensing, change detection and image classification. Classification was performed in principles of object-oriented classification, using Erdas software tool. The benefits of automatic classification process in the preparation of such a complex system are analysed together with aspects of application and implementation of LPIS in analised area of Pancevo.
