Talajkartográfia, also known as soil cartography, is the branch of science that deals with the representation of soil information on maps. It involves the systematic collection, interpretation, and graphic display of data related to the distribution, characteristics, and properties of soils within a defined geographic area. The primary goal of soil cartography is to provide a spatial understanding of soil resources, which is crucial for various applications such as agriculture, land-use planning, environmental management, and engineering.

The process of creating soil maps typically begins with field surveys, where soil scientists examine the land, dig soil pits, and describe soil profiles. These observations, along with information from aerial photographs, remote sensing data, and existing geological or topographical maps, are used to delineate areas with similar soil properties. These delineated areas, known as mapping units, are then represented on a base map. Each mapping unit is assigned a symbol or name that corresponds to a detailed legend explaining the soil type and its characteristics, including texture, structure, color, depth, drainage, and other relevant features.

The scale of a soil map is a critical factor, determining the level of detail and the intended use. Large-scale maps, typically at scales of 1:15,000 or larger, are suitable for detailed planning, such as farm management or site-specific construction. Small-scale maps, conversely, provide a broader overview of soil distribution across larger regions and are useful for regional planning and general land resource assessments. Soil maps are dynamic documents, often updated as new information becomes available or as soil conditions change over time due to land use or environmental processes.
