dc.description.abstractCreating a Sound Map requires an Environmental map and a Source Model. Digitizing environmental maps requires time and the time required depends on the size of the map. It would be easier to import readymade maps as many national survey authorities provide map data publicly. The aim of this thesis was to check the viability of importing freely available data to create environmental map for sound model creation. Finland was used as a model and different types and formats of data was tested to con-clude the optimal format for different objects required for environmental maps. Soft-ware SoundPLAN 7.2 was majorly used for the task with minor usage of ArcGIS. Las2txt was used to translate LAZ data to ASCII. ASCII was optimal format for terrain and surface points, Buildings and roads were best imported as ESRI or DXF formats. LAZ was required and used after translated to AS-CII for building and structure height when it was unavailable in ESRI or DXF metadata. National Map data were the most reliable followed by Open source where self validation is required before use. The process of importing freely available data to create environmental maps was found to be possible for any part of the world with varying level of convenience depending on the data available and overall the method was found to save considerable time compared to manual digitization of data.en
