Spatial data is also known as geospatial data, spatial information or geographic information.
synonyms for spatial
On this page you'll find 6 synonyms, antonyms, and words related to spatial, such as: dimensional, geographical, contiguous, and structural.
Spatial data are of two types according to the storing technique, namely, raster data and vector data. Raster data are composed of grid cells identified by row and column. The whole geographic area is divided into groups of individual cells, which represent an image.
Spatial analysis is often referred to as modeling.
Spatial data is information about where observations are in relation to each other. Usually, this means that one of the dimensions associated with each observation describes that record's position in space.
Spatial analysis allows you to solve complex location-oriented problems, explore and understand your data from a geographic perspective, determine relationships, detect and quantify patterns, assess trends, and make predictions and decisions.
GIS data can be separated into two categories: spatially referenced data which is represented by vector and raster forms (including imagery) and attribute tables which is represented in tabular format.
This type of information contains things such as an address with a city, state, and zip code. It also can contain latitude and longitude to identify a point on the map. Maps are the most logical example of geospatial data.
Published. October 25, 2021. Spatial data, also known as geospatial data, is a term used to describe any data related to or containing information about a specific location on the Earth's surface. Non-spatial data, on the other hand, is data that is independent of geographic location.
Not surprisingly, spatial is from the Latin word spatium for "space." Definitions of spatial. adjective. pertaining to or involving or having the nature of space.

The two major types of GIS file formats are raster and vector. Raster formats are grids of cells or pixels. Raster formats are useful for storing GIS data that vary, such as elevation or satellite imagery. Vector formats are polygons that use points (called nodes) and lines.
The main difference between attribute data and spatial data is that the attribute data describes the characteristics of a geographical feature while spatial data describes the absolute and relative location of geographic features.
Geospatial data helps us to understand the world, and it can also help us to discover hidden spaces. Underground networks and caves for example, can be hard to access and explore. With geospatial data, it's possible to create a digital model or photographic interpretation of an area that has never been explored before.
Types of spatial patterns represented on maps include absolute and relative distance and direction, clustering, dispersal, and elevation.
A spatial data layer is either a representation of a continuous or discrete field, or a collection of objects of the same kind. The main principle of data organization applied in a GIS is that of spatial data layers. Usually, the data are organized such that similar elements are in a single data layer (Figure 1).
GIS, or geographic information systems, are computer-based tools used to store, visualize, analyze, and interpret geographic data. Geographic data (also called spatial, or geospatial data) identifies the geographic location of features.
Two Primary Types of Data Models
There are two types of data models that you will use regularly within a GIS: Vector (points, lines, and polygons) Raster (made up of "pixels")
Important characteristics of spatial data are its measurement level, map scale and associated topological information. Nominal, ordinal, interval and ratio are the four levels of measurement for populating the spatial data matrix; they hold different amounts of information and determine what analysis can be performed.
Both “geospatial” and “GIS” are concerned with mapping data or locations. The term “spatial” is even broader in scope. In most situations, you can interchangeably use any of these terms without getting yourself in trouble.
GIS integrates many different kinds of data layers using spatial location. Most data has a geographic component. GIS data includes imagery, features, and basemaps linked to spreadsheets and tables.
A working GIS integrates five key components: hardware, software, data, people, and methods. Hardware is the computer on which a GIS operates.
GIS has five layers, which are spatial reference framework, spatial data model, spatial data acquisition systems, spatial data analysis, and geo-visualization.
