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 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 ]
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.
OneGeology is an international collaborative project in the field of geology supported by 118 countries, UNESCO, and major global geoscience bodies.It is an International Year of Planet Earth flagship initiative that aims to enable online access to dynamic digital geological map of the world for everyone.
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.
A world map is a map of most or all of the surface of Earth. World maps, because of their scale, must deal with the problem of projection. Maps rendered in two dimensions by necessity distort the display of the three-dimensional surface of the Earth. While this is true of any map, these distortions reach extremes in a world map.
A simple vector map, using each of the vector elements: points for wells, lines for rivers, and a polygon for the lake A vector dataset (sometimes called a feature dataset) stores information about discrete objects, using an encoding of the vector logical data model to represent the location or geometry of each object, and an encoding of its ...
