Republik Krakau
In 1830s, Żebrawski designed and built a road through the Free City of Kraków with two bridges over Krzeszówka and Dłubnia. Between 1825–1831, he made a triangulation of Dobrzyń Land, Pułtusk obwód, Świętokrzyskie Mountains, Sandomierz region, regions between Warsaw, Włodawa and Bug, and Wilno Governorate region. Part of these measurements were used in the 1839 map of Kingdom of Poland.
