Dear Colleagues,

In the present era of rapid population growth in cities, administrative units are facing many difficult challenges in providing housing resources, jobs, education, care, and recreation. Friendly urban space with access to all functional facilities, including green and blue infrastructure for all social groups, is a priority, not only for the local community but most importantly on a global basis, as evidenced by the international institutions, i.e., World Health Organization (WHO—Age-friendly city), United Nations International Children’s Emergency Fund (UNICEF—Child-friendly cities), United Nations Department of Economic and Social Affairs (Sustainable Development Goals—SDG), European Commission (EC—Green Infrastructure), and others. Local solutions have a massive impact on global sustainability. In combination with the concern for increasing the quality of life in cities, effective and sustainable land administration requires unlimited access to complete, often with integrated data on various phenomena in the urban space. Geoinformation management is the first and basic stage of the administrative decision-making process. Geoinformation serves not only the governments but also the city inhabitants to support small everyday decisions, e.g., concerning the choice of an access road, as well as bigger ones concerning real estate investments. Access to current and complete geoinformation and skillful processing of it provides knowledge in almost every aspect of our lives. The question of what data sources are reliable and credible and how to process the acquired geo-information is still valid. On the part of producers of geodata from different sources, the challenge is to provide them with the highest possible quality, which will enable seamless integration.

The aim of this Special Issue is to share the latest achievements in the development of geoinformation databases, their integration, and the latest processing methods to achieve the goals of a smart and friendly city.

Of high importance is currently research on the purpose of geoinformation for urban sanitation improvements related to the COVID-19 pandemic; green infrastructure creation; friendly real estate housing developments, especially for seniors and children; smart transportation and congestion management; crisis management.
