GIS IN SOIL SURVEY AND SOIL MAPPING

open access: yesGeodesy and cartography, 2021
The main goal of this paper is to present a methodology for land evaluation by supporting decision-makers with reliable information for the land-use planning process. One of the focuses of this paper is given to the survey process and interpretation between soil survey, soil survey interpretation, and physical land evaluation.

Global maps of soil temperature [PDF]

open access: yesGlobal Change Biology, 2021
AbstractResearch in global change ecology relies heavily on global climatic grids derived from estimates of air temperature in open areas at around 2 m above the ground. These climatic grids do not reflect conditions below vegetation canopies and near the ground surface, where critical ecosystem functions occur and most terrestrial species reside. Here,

Harmonisation of a large-scale historical database with the actual Czech soil classification system

open access: yesSoil and Water Research, 2020
The possibility of the adequate use of data and maps from historical soil surveys depends, to a large measure, on their harmonisation. Legacy data originating from a large-scale national mapping campaign, "Systematic soil survey of agricultural soils in ...
