SoilGrids1km is a collection of updatable soil property and class maps of the world at a resolution of 1 km produced using state-of-the-art model-based statistical methods. Presents estimates (means and 90% confidence intervals) for pH, texture (sa, si, cl), organic carbon and more for 6 depth layers up to 2 m depth.
The 22 maps of the Geological Atlas of the World were co-published by CGMW and UNESCO from 1974 to 1984. In January 1983, the wall map concept of the Geological Map of the World was revived at the UNESCO G.A. [10] and the 1st edition at 1:25M scale was published in 1990. For the first time, continental geology was shown, alongside ocean geology ...
Shapefiles : are a data exchange format created by ESRI and one of the most widely used GIS/geodata formats. One "shapefile" usually include four different files : .shp, .shx, .dbf, .prj. First three files must all be present in order to use the data. Each shapefile can hold only one geometry type.
A geologic map or geological map is a special-purpose map made to show various geological features. Rock units or geologic strata are shown by color or symbols. Bedding planes and structural features such as faults , folds , are shown with strike and dip or trend and plunge symbols which give three-dimensional orientations features.
The Global Geoparks Network (GGN) (also known as the Global Network of National Geoparks) is UNESCO assisted network established in 1998. Managed under the body's Ecological and Earth Sciences Division, the GGN seeks the promotion and conservation of the planet's geological heritage, as well as encourages the sustainable research and development by the concerned communities.
The shapefile format is a geospatial vector data format for geographic information system (GIS) software. It is developed and regulated by Esri as a mostly open specification for data interoperability among Esri and other GIS software products . [ 1 ]
Approaches for representing three-dimensional map information, and for managing it in the data model. [31] Vector-based stack-unit maps depict the vertical succession of geologic units to a specified depth (here, the base of the block diagram). This mapping approach characterizes the vertical variations of physical properties in each 3-D map unit.
