This is a list of GIS data sources (including some geoportals) that provide information sets that can be used in geographic information systems (GIS) and spatial databases for purposes of geospatial analysis and cartographic mapping. This list categorizes the sources of interest.
Specifically, Geospatial Information Agency is tasked to chair the One Map Policy Implementation Team as stipulated in Chapter 6, Article 3 of the regulation. [3] Furthermore, this agency is also responsible to assist the Acceleration Team chaired by Indonesia's Coordinating Ministry of Economic Affairs to resolve land and map conflicts as the ...
The actual shapefile relates specifically to the .shp file, but alone is incomplete for distribution as the other supporting files are required. In line with the ESRI Shapefile Technical Description , [ 1 ] legacy GIS software may expect that the filename prefix be limited to eight characters to conform to the DOS 8.3 filename convention ...
Geospatial metadata (also geographic metadata) is a type of metadata applicable to geographic data and information.Such objects may be stored in a geographic information system (GIS) or may simply be documents, data-sets, images or other objects, services, or related items that exist in some other native environment but whose features may be appropriate to describe in a (geographic) metadata ...
Google Earth is a web and computer program that renders a 3D representation of Earth based primarily on satellite imagery.The program maps the Earth by superimposing satellite images, aerial photography, and GIS data onto a 3D globe, allowing users to see cities and landscapes from various angles.
A GIS file format is a standard for encoding geographical information into a computer file, as a specialized type of file format for use in geographic information systems (GIS) and other geospatial applications. Since the 1970s, dozens of formats have been created based on various data models for various purposes
Web GIS has numerous functions, which can be divided into categories of Geospatial web services, including web feature services, web processing services, and web mapping services. [3] Geospatial web services are distinct software packages available on the World Wide Web that can be employed to perform a function with spatial data.
A polygon mesh (related to the mathematical polyhedron) is a logical extension of the vector data model, and is probably the 3-D model type most widely supported in GIS. A volumetric object is reduced to its outer surface, which is represented by a set of polygons (often triangles) that collectively completely enclose a volume.
