The World Urban Database and Access Portal Tools (WUDAPT) is a global initiative of tools to create local climate zone maps for a given city using a standard methodology. [1] It has both a database and a portal. The database has hierarchical layers of increasing detail, with data acquired via crowdsourcing methods such as Geo-Wiki. [2]
The climate and ecology of different locations on the globe naturally separate into life zones, depending on elevation, latitude, and location. The generally strong dependency on elevation is known as altitudinal zonation : the average temperature of a location decreases as the elevation increases.
These zones amounts to about half of Earth's land surface, the remaining half cannot be explained in simple terms by climate-landform interactions. [5] The limitations of morphoclimatic zoning were already discussed by Siegfried Passarge in 1926 who considered vegetation and the extent of weathered material as having more direct impact than ...
Figure 1. The relationship between Zone and Site Classifications. The Biogeoclimatic Subzones/variants portion of the diagram shows three climatic regions (IDFdm1, MSdm1, & ESSFdc2). Each has a set of Site Series, that describe the local ecosystems on the landscape. The Site Series are coded with a number (e.g., 101, 102, etc.)
Climate classifications are systems that categorize the world's climates. A climate classification may correlate closely with a biome classification, as climate is a major influence on life in a region. The most used is the Köppen climate classification scheme first developed in 1884.

The Köppen climate classification system was modified further within the Trewartha climate classification system in 1966 (revised in 1980). The Trewartha system sought to create a more refined middle latitude climate zone, which was one of the criticisms of the Köppen system (the climate group C was too general). [10]: 200–1
Today, the most commonly used climate map is the Köppen climate classification, developed by Russian climatologist of German descent and amateur botanist Wladimir Köppen (1846–1940), which divides the world into five major climate regions, based on average annual precipitation, average monthly precipitation, and average monthly temperature.
