See ArcGIS field data types for more information. Geometry ST_Geometry, Geometry (PostGIS), Geography (PostGIS) In a geodatabase, the GEOMETRY_STORAGE setting of the configuration keyword used when creating th
Vector data is the most common type of GIS data. Most data loaded into aGIS software programtends to be in vector data. Vector data represents geographic data symbolized as points, lines, or polygons. Raster data represents geographic data as a matrix of cells that each contains an attribute...
As indicated in the table, ArcGIS creates and can work with three spatial data types in PostgreSQL: Esri ST_Geometry, PostGIS geometry, and PostGIS geography. The next two sections provide more background on these data types. ST_Geometry The following is a general description of the ST_Geom...
ArcGIS enables interoperability of all GIS data types, formats, and specifications of data. Users can bring vector and raster data into and out of the system in their format of choice. Many organizations also use ArcGIS to share and work with open data so they can communicate effectively, ...

Imagery basemap—A processed, orthorectified image or collection of image tiles that has the integrity of a map and is used for a reference. Image basemaps are commonly used for a backdrop to GIS data for context and are often color balanced for optimum visual appeal. Thus, they may ...
Python is one of the easier to get started in programming languages, and can very efficiently implement map data visualization of large amounts of data. The Python map visualization library has well-knownpyecharts,plotly,folium, as well as slightly low-keybokeh,basemap,geopandas, they are also...
STDistance function output for Geography data might have minor precision variations compared to T-SQL. This is due to the underlying PostGIS implementation. For more information, seeST_Distance For optimal performance, use built-in Geospatial data types, without creating additional layers of abstraction...
You’ll often seeflow mapsfor migration patterns, trade routes, or traffic flow. They show where things start and end, adding the dimension of when. 5. Space-Time Cube Maps Space-time cubesshow data across both space and time within a 3D framework. We use them sparsely in GIS. But they...
Portals allow users to store and share a variety of items. Each item has a type, such as Web Map or Feature Service, and a set of type keywords that provide additional information about the characteristics of the type.
