Today, more than half of the world's population lives in urban areas, and this percentage is increasing every day. Accelerated urbanization leads to overbuilding, air and environmental pollution, climate change, and various other environmental problems. One of the ways to solve these problems is the planning of green infrastructure (GI). The development of GI brings a number of social, ecological, and economic benefits, and it is one of the ways to achieve sustainable development. Therefore, it is important to include GI in land management systems. This study used VOSviewer to analyze 4385 published papers in the field of GI and 110 studies on GI in combination with land management, land administration, LADM, and land use planning from the WoS database for the periods from 1995 to 2022 and from 2007 to 2022, respectively. The current research used the bibliometric method to see what the trends are in GI and how much GI has been researched for the purpose of land management. It was shown that researchers are giving more and more importance to GI, but GI in land management systems is still not sufficiently researched. [ABSTRACT FROM AUTHOR]

Efficient management of space resources is one of the main factors of prosperous economic development of an area. Technological development enables an integration of attributes linked to space, creating a spatial informational support for increasingly more complex social communities. An important component of these systems is mass real estate valuation, especially in urban areas. The paper explains data modelling and storage of a 3D test area space model into a spatial database and describes a procedure of visibility calculation as a real estate valuation factor for a part of the City of Zagreb. In the paper, visibility is presented as a visibility polygon, a two-dimensional geometric shape drawn by intersecting a continuous visibility border in all directions from the object weight centre, considering the intersection of horizontal vision and obstacles. A matching visibility polygon is attached to each building in the whole test area, under the assumption that the polygon area can be correlated to a positive or negative influence on real estate value. The speed of the visibility calculation function in the test system was measured. [ABSTRACT FROM AUTHOR]
