Map of the month June 2025: Imperviousness Comparison 2009 – 2018
On the occasion of World Environment Day (5 June) we are going to take a look at the changes in imperviousness in the Centrope region. The comparison is done using satellite-image-based data layers from the European Environment Agency. Imperviousness, i.e. the covering of soil with non-permeable materials such as concrete or asphalt, has a significant impact on the climate. It reduces the soil's ability to store carbon and absorb water, which can lead to higher temperatures in cities and an increase in flooding risk.
Map of the month May 2025: International Family Day
15 May was adopted as the International Day of Families by the UN General Assembly. This day provides an opportunity to promote awareness of issues relating to families and to increase the knowledge of the social, economic and demographic processes affecting families. On this occasion we take a look at the martial status of population. We calculated an marriage activity indicator showing the quota of married, divorced and widowed to never married. The indicator shows lower values in the areas with higher population density and younger population. In Hungary, the values are on significantly higher level throughout the whole part of the Centrope region.

Map of the month April 2025: Tree Cover Density Comparison 2012 – 2018
This month we are going to take a look at the changes in tree cover density in the Centrope region. The comparison is done using the tree density cover layer from the European Environment Agency, which is a satellite-based evaluation of the tree top cover. The coverage of the ground by trees and their tops is displayed continuously from 0 to 100 %. The comparison shows that between 2012 und 2018 the tree cover became denser. However, if you closely look at smaller spots, many of them seem to have disappeared, which can be interpreted as a sign of progressive soil sealing. Some changes may also have occurred due to differences in automatic image interpretation due to season and weather condition at the time of satellite image generation.

Map of the month February 2025: Corine Land Cover Comparison 2000 – 2018
This month we are going to take a look at the changes in land use in the Centrope region. The comparison is done using Corine Land Cover, which is a satellite-based land use map showing real land use in 34 different categories. The comparison shows that between 2000 und 2018 urban areas became denser and also some smaller villages underwent some slight changes in size. However, the overall land use in the past 20 years did not change much. Some changes between adjacent categories (one up or one down in map legend) may also have occurred due to differences in automatic image interpretation due to season and weather condition at the time of satellite image generation.
