In Latvia, the issues of the Real Estate Cadastre are arranged; however, it should be noted that part of the issues affecting the Baltic Sea, i.e., the issues of the Marine Cadastre, are not covered by the Real Estate Cadastre. The status of the Baltic coastline is an essential element of infrastructure for all countries around the Baltic Sea. This baseline serves as the key element or reference for the Marine Cadastre. In place-to-place, this line is the dynamic element as it is possible to monitor location with advanced and progressive technologies. The issues of the Marine Cadastre are on the agenda in many EU countries, and several internаtional projects are being reаlized. Land parcels from the sea are registered and maintained in the Cadastre Information System in Latvia. Starting from 2017, the State Land Service of Latvia has started to register coastal areas two kilometres in width from the Baltic Sea baseline. Cadastral information about the Marine Cadastre is being used for spatial planning and taxation.
