Improvement of the CROTIS Topographic Model for the Objects of the Buildings and Traffic

Sa？etak In 1992, the State Geodetic Administration started working on the Official Topographic Cartographic Information System (STOKIS), which defined the topographic and cartographic data model. The STOKIS guidelines produced a Croatian Topographic Information System (CROTIS) as a data model based on which the Basic Topographic Database (BTD), 2003-2010 was established. Two very important themes of CROTIS 2.0 that are most commonly used are Buildings and Traffic. The article will provide an insight into the need to expand/correct the BTD data model. Each profession or activity has its own specifics and needs, so it is necessary to improve the existing model of CROTIS in order to use the BTD data as useful and useful as possible in other sectors (e.g. for Spatial planning, Croatian Motorways and Croatian Roads, Croatian waters, Croatian forests, etc.), all in line with international standards and INSPIRE directive
