exportare imagine tif clasificata in format vector

Benedic Codrut George
Buna ziua,

Daca am imaginea in format tif de la link-ul atasat

https://we.tl/t-Ku6QbCM0eF

clasificata, cum pot ca sa o export in format vector, dar sa-mi pastreze
culorile claselor?

Cand export imaginea tif ca vector, imi pune totul pe o singura culoare.
Ma intereseaza ca sa obtin mai multi vectori, corespunzatori claselor de
culori ale imaginii respective.

Multumesc!

Re: exportare imagine tif clasificata in format vector

Bună,
Cred că solutia este sa faci o reclasificare a rasterului, acordand fiecarei clase cate un cod. Ex: intervalul 0-100 => 1, etc.In QGIS, instrumentul se numeste Reclasificarea dupa tabela (din meniul Analiza Rasterelor)..In ArcGIS, Reclassify din meniul Spatial Analist Tools.
Apoi, rasterul reclasificat (care va avea doar coduri pentru fiecare interval de valori) poate fi convertit in vector (poligon). Noul vector va contine in tabela de atribute un camp cu valorile claselor din raster. Ulterior, poti redenumi clasele si le poti atribui simbologia. 
Sper să funcționeze!

Re: exportare imagine tif clasificata in format vector

mn_geogr
Am utilizat Raster / Conversion / Polygonize (Raster to Vector), am copiat culorile din raster si iata rezultatul. Ce nu stiu si nu am cum sa rezolv eu sunt datele valorilor utilizate ca limita intre clase, existand pixeli necolorati. In rasterul tau Tu stii cel mai bine ce clase da valori ai si poti modifica la simbologie valorile.
Am trimis pe email vectorul si fisierul de stil QGIS.
Spor!
