30DayMapChallenge 2024
The worldwide #30DayMapChallenge in Estonian Land Board.
For every day in November one new map will appear in the gallery on this page. The authors of the maps are "cartgoraphy lovers" of the Land Board, who dared to take up the challenge in order to learn something new.

Day 4. Hexagons. Estonia has over 760,000 cadastral units, whose boundaries are defined by precise border points, totalling over 5.5 million. There are over 11.7 million connections between cadastral units and border points in Estonia. The data on cadastral units and boundary points provides a comprehensive overview of our land areas and their use. The map displays the number of points within each hexagon by the hexagon’s size and indicates the median age of points by colour. For a closer look at cadastral data, visit minukataster.

Day 1. Points. According to European tradition, house numbers are assigned in a one-way ascending order, with even numbers on one side of the street and odd numbers on the other. The rule about whether even numbers are on the left or the right, when looking along the street in the direction of ascending numbers, varies by region. However, exceptions can be found everywhere, with individual houses or even entire blocks disregarding the local rule.
Day 2. Lines. To acquire land for the Rail Baltica corridor and service facilities, designated portions of land parcels need to be separated. In recent years, this has led to the creation of so-called temporary land units, which are planned to be merged into a single cadastral unit in the near future. Now, interestingly shaped cadastral units can be found on the map of Estonia – long and narrow parcels and circular land areas. Together, these fragments form a large puzzle across Estonia, allowing us to trace the emergence of a new linear spatial object. For further information, you can read a dedicated article on the website of the Land Board.
Day 3. Polygons. Estonia's cities are modest in population, but comparable in area size to some of the major metropolises in different parts of the world. The map visualizes the three largest Estonian cities that were formed as a result of the 2017 administrative reform, with an example of a comparable metropolis for comparison.
