Geology / Litology :Classification of bedrock geology according to composition and structure of bedrock. A variety of classification systems. EuroGeoSurveys coordinates harmonisation processes

General data used to understand regional environmental diversity, to study geo-chemical content and effects on natural environment and health, to estimate buffer capacities in soil, to locate groundwater aquifers in bedrock.

Soils :
Categorisation of soils and subsoil according to depth, texture, structure and content of particles and organic material, stoniness, sometimes mean slope and anticipated water storage capacity. FAO nomenclature is widely used, with 350 soil classes, Existing dataset in small scale. CORINE soils, later developed by JRC to soil type database for Europe: A digital map, 1: 1 mill, European coverage.Large scale data common in agricultural land.
Important
in assessment and mangement of soil as a resource for agriculture and forestry, including also special effects such as erosion, salinisation, desertification. Aslo used in location of areas for gravel and peat extraction, groundwater resources, as a habitat.
 

Geomorphology :
Geomorphological processes and results of processes, commonly monitored both as landscape changes and as potential risks. Important also in loss of land and gain of land.

Example: coastal erosion and progradation
land rise, natural hazards – land slide probability assessments.
Erosion: Land, slopes and coast are evolutionary and changing over time due to erosion. Erosion is accelerated by human intervention. Erosion risk data for land and coast represent a reference data towards assessment of general trends and anthropogenic pressures.

Relevant in agriculture, forestry, in coastal management, and in actions to combat desertification. Can be divided into
- monitoring of actual soil erosion
- modelling erosion risk
