GLA VAČ\u27S WORK ON MAPPING OF THE WESTERN CROATIA

U ovome radu najprije je objašnjena geodetska izmjera u ranom novom vijeku. Pritom je izlaganje podijeljeno na probleme više geodezije i one topografske izmjere. U to vrijeme Zemlja je smatrana kuglom te su zadaci više geodezije bili pretežno u vezi s određivanjem veličine Zemljine kugle. Opisane su terestričke metode sferne geodezije s naglaskom na metodu Marina Getaldića. Uz te čisto geometrijske metode, javljaju se linearno-astronomske i trigonometrijsko-astronomske metode. Tu je posebno važan postupak triangulacije koj je značajan za geodeziju od toga vremena pa sve do danas. Picardova mjerenja iz druge polovice 17. st. posljednji su geodetski poduhvati kod kojih je kugla uzeta za obhk Zemlje. Topografska izmjera je prikupljanje sadržaja originala topografskih karta. Od razhčitih metoda izmjere čini se da se Glavač služio jednostavnim pos­tupcima, kao što su određivanje smjera kompasa s grubom podjelom kutova, određivanjem udaljenosti pomoću mjerenja koraka ili vremena putovanja. U radu su opisane metode topografske izmjere u to doba u nekim europskim zemljama. Pri analizi Giavačeve karte pokušano je odgovoriti na pitanje o prethod­nim terenskim radovima, usvojenim dimenzijama Zemljine kugle, mjerilu karte i kartografskoj projekciji. Posebno je objašnjen način prosudbe o točnosti prikaza na karti. Na kraju rada se zaključuje da je Glavačeva karta jedno od kapitalnih djela hi-vatske kartografije 17. stoljeća te da nakon provedenih istraživanja ostaje otvoren još cijeh niz pitanja koja očekuju odgovor u budućnosti.The paper starts with the illustration of geodetic survey in the early new era. The report is classified into the problems of higher geodesy and those of topographic sui-vey. At that time the Earth has been considered a globe and the tasks of higher geodesy were mostly connected with the determining the size of the Earth\u27s globe. The terrestrial methods of spherical geodesy are described with an ac­cent on the method by Marin Getaldic. Along with these purely geometrical methods, there are also linerar and astronimical, and trigonometric and astronomical methods applied. The triangulation procedure is of a special importance here being significant for geodesy from that time up to now. Picard\u27s measurements from the second half of the 17th century are the last geodetic activities in which the globe was taken as the Earth\u27s model. The topographic survey implies gathering the contents of the topographic map originals. Among various surveying methods Glavač seems to have ap­plied simple procedures as for example the determination of the direction by means of compass with a rough angle classification, the determination of dis­tance by means of pacing or travelling time. The work describes the methods of topographic survey in the those days in some European countries. While analysing the Glavač\u27s map, one has tried to answer the question about previous field works, adopted dimensions of the Earth\u27s globe, mapscale and map projection. The way of estimating the accuracy of the map presentations has been especially explained. At the end of the work it is concluded that the Glavač\u27s map represents of the crucial works in Croatian cartography of the 17th century, and that afterthe research has been carried out, there are stil many questions remaining open for the future to find the answers for them
