Damir Magaš, 2020., Karst Fields (Polja) of Lastovo Island, Croatia, on Topographic Maps (1: 25,000) (Abstract)

In the chapter abstract, the author considers the graphical depictions of the Lastovo Island karst fields on older and newer topographic maps (1: 25000) from the 19th and 20th centuries. The Lastovo is the sixteenth by area, and only eighteenth by population among Croatian islands (2011.). It belongs to the South Dalmatian islands within the Dubrovnik-Neretva County (Adriatic Croatia) and including its associated islands and islets it makes a separate municipality covering 56.00 km2 (Lastovo itself 40.82 km2) with 792 residents (2011) . The carbonate relief with many karstic forms (caves, abyss, cliffs, rocks, karst fields, creeks etc.) prevails. Although relatively small, the fields have been important geomorphologic phenomena in the karst relief of Lastovo and since ancient times they had great importance for settling, living and surviving the inhabitants of its settlements. On the Lastovo there are almost forty small karst fields (Ubli: 1. Vino polje, 2. Nižno polje, 3. Šupalj do (Šipanj do), 4. Jurjev do, 5. Zle polje (Ubli) ; Lastovo: 1. Zlepolje (Lastovo), 2. Žegovo polje, 3. Hrastovo polje, 4. Volji dolac, 5.-8. Dubrava – Lokavje – Ždr(i)jelo – Peržina, 9. Bozonji do, 10. Kosovo, 11. Uresovi (Vrsej) dolac, 12. Duboke, 13. P(e)rgovo, 14. Čuča(l)j do, 15. Barje, 16. Kal?, 17. Velja (Velika) lokva, 18. Dosibje do, 19. (U)Dovin do, 20. Pršnaš do 21. Studenac, 22. Poljice, 23. Kruševa njiva, 24. Radaš do, 25. Veliko dolce, 26. Malo dolce ; Crljena Luka (Portorus): 1. Gornji Portorus, 2. Portorus). Regardless of their importance, they are depicted rarely on topographic maps, except in those of 1: 25, 000, from the Habsburg Empire (1869-1887) - Third Military Survey 1: 25000 to the contemporary topographic Croatian DGU maps with multiple field markings. Special considerations are given to the field names, the visualization of the objects and the contents within the fields (cultivated areas, culture, appearance of water, drywall, constructed objects, etc.), to the hipsographic features, contact zones around the fields features, belonging to settlements on the island etc.
