Kad ovo provučem kroz QGIS i kažem da mi nađe length($geometry)
vrati mi isto 2708m (a stvarnost je, kao što ti kažeš 700m)! Deluje kao da ova linija u RGZ-u ide cik-cak, ali se to ne vidi! Samo ovaj prvi južni deo od Filipa Višnjića do Žive Jovanovića je u RGZ-u predstavljen kao:

što je u stvarnosti 85m, a ovaj RGZ linestring je 288m. Ako pogledaš malo bolje ovaj linestring iznad, videćeš da je ovo zapravo jedna linija koja ide gore-dole (npr. 45.12103451432022
se uvek ponavlja…).
Ovde verovatno treba nekako uprostiti geometriju iz RGZ-a, ali ne znam kako ovo uraditi, prevazilazi moje znanje (“ne mogu ja da popravim koliko RGZ može da pokvari”). Nažalost, predajem se ovde, ne mogu da rešim ovo, ali lepo si primetio, svaka čast:)
