Description (Dublin Core)

eng Operational mapping of crop/agricultural parcel boundaries is a challenging task. It should be efficient and inexpensive process resulting with data useful for wide range of purposes. Hard classification of medium resolution (>15 m, <30 m) remote sensing data could be a solution but the spatial resolution of the imagery is not sufficient for many applications. In this paper a method for soft classification of medium remote sensing data and super-resolution mapping of crop boundaries is presented. The method is developed based on localized partial unmixing with estimating both target and background end-member spectra. The output was subjected to pixel swapping as super resolution mapping technique. Testing is done on real Landsat ETM+ imagery. The method is evaluated quantitatively and the results show significant increase of accuracy when compared to mapping from original remote sensing data.

hrv Operativno kartiranje međa poljoprivrednih/žitnih parcela je izazovni zadatak. To bi trebao biti učinkovit i isplativ postupak koji bi rezultirao podacima korisnima za široku upotrebu. Gruba klasifikacija podataka daljinskog istraživanja srednje rezolucije (>15 m, <30 m) mogla bi biti rješenje, no prostorna rezolucija snimaka nije dovoljna za mnoge primjene. U ovom radu predstavljena je blaga klasifikacija podataka daljinskog istraživanja srednje rezolucije te kartiranja žitnih parcela super rezolucije. Metoda je razvijena na temelju lokaliziranoga parcijalnog razdvajanja procjenjujući spektar krajnjeg člana i cilja i pozadine. Rezultat je bio podvrgnut razmjeni piksela kao tehnike kartiranja super rezolucijom. Ispitivanje se provodi na stvarnim snimkama Landsat ETM+. Metoda je vrednovana kvantitativno, a rezultati pokazuju značajnu točnost u usporedbi s kartiranjem iz originalnih podataka daljinskog istraživanja.
