JNA topografske karte — Srbija, razmera 1:50 000
JNA topografske karte razmere 1:50 000 bile su standardni topografski listovi proizvodnje Jugoslovenske narodnooslobodilačke armije i kasnije Vojske Jugoslavije, koji pokrivaju teritoriju Srbije i šire. Karakteristike i upotreba:
Karte sadrže precizne prikaze reljefa (izohipse), hidrografije, vegetacije, naselja i putne infrastrukture koji su i danas relevantni za orijentaciju u teško prohodnim predelima. Vremenski okvir: JNA Topografske karte -Srbija- Razmera 1-50000
- Korigovani grid: Neki programi (kao što je Global Mapper, QGIS ili SAS Planet) imaju ugrađene transformacione parametre za "Yugoslavia 1950" datum.
- Ručno kalibrisanje: Iskusni korisnici skeniraju staru mapu i u programu OziExplorer ili Google Earth Pro ručno je georeferenciraju pomoću vidljivih tačaka (raskrsnice puteva, vrhovi).
- Odmor od tehnologije: Mnogi planinari koriste JNA kartu kao primarni izvor, a GPS samo za proveru nadmorske visine. Karta + kompas + altimetar su pouzdaniji od baterije.

6. Cartographic Quality & Accuracy
- Horizontal accuracy: ±10–15 meters (remarkable for pre-GPS era).
- Vertical accuracy: ±5–7 meters (due to 10m contours).
- Field verification: JNA mapping teams physically verified all roads, trails, and structures – often walking every path.
- Revisions: Maps were updated every 5–10 years via aerial reconnaissance and local intelligence.
- Deliberate distortions: Unlike Soviet maps, JNA maps are widely considered trustworthy – no systematic terrain falsification, though military objects were sometimes omitted or mislabeled.
