well identified and provided with detailed standardized descriptions. Surveys and mapping The work of the Commission is supported by geographical information and mapping resulting from topographic surveys in Antarctica, such as the 1995/96 survey in Livingston Island, and the topographic survey Tangra 2004/05. Field work carried out during the latter survey has been noted by Discovery Channel, the Natural History Museum, the Royal Collection and the British Antarctic Survey as a timeline event in Antarctic exploration. The Commission published the first Bulgarian topographic map of Livingston Island and Greenwich Island in 2005, and jointly with the Military Topographic Service of the Bulgarian Army, the first detailed topographic map of Smith Island in 2009. International cooperation The Antarctic Place-names Commission cooperates with other national authorities for Antarctic place names, and with the Scientific Committee on Antarctic Research (SCAR). Details of the Bulgarian Antarctic toponyms are published by the Commission's website, and also by the international Composite Gazetteer of Antarctica maintained by SCAR. The names are featured by various maps, including the SCAR Antarctic Digital Database (ADD). Antarctic names in Bulgaria In order to promote Antarctic exploration and the presence of Bulgaria in Antarctica, the Commission encourages Bulgarian municipalities to give relevant Antarctic names to public places. Several squares and streets in Bulgarian settlements are named after Livingston Island, such as Livingston Island Square in Samuil and Kula; Livingston Island Street in Gotse Delchev, Yambol, Petrich, Sofia, Lovech and Vidin; Antarctica Street in Dzhebel and Antarctica Park in Kilifarevo.
