There are four typical data types that we use in GIS: integer, float/real, text/string, and date.
Non-spatial data are stored in GIS as tables. Such tables are known as non-spatial (attribute) tables. A non-spatial table is represented by rows and columns in which each row shows a spatial feature and each column represents a characteristic.
Spatial data can have any number of attributes about a location. For example, this may be a map, photographs, historical information or anything else that may be deemed necessary.
• Non-spatial data (also called attribute or characteristic data) is that information which is independent of all geometric considerations. o For example, a person's height, mass, and age are non-spatial data because they are independent of the person's location.
Any additional information, or non-spatial data, that describes a feature is referred to as an attribute. Spatial data can have any amount of additional attributes accompanying information about the location. For example, you might have a map displaying buildings within a city's downtown region.
non·spa·tial ˌnän-ˈspā-shəl. : not spatial: such as. : not relating to, occupying, or having the character of space. nonspatial data. : not relating to or involved in the perception of relationships (as of objects) in space.
Time is supported in spatial data in a variety of ways. Time information can be stored as an attribute (feature classes, stand-alone tables, and mosaic datasets), or it can be stored internally (such as in netCDF data). The following sections describe data that can be visualized through time.
1.4 Data Model. The Spatial data model is a hierarchical structure consisting of elements, geometries, and layers, which correspond to representations of spatial data.
The non-spatial data in a GIS are presented in tables that make up a database linked to the map. The geographic features in the table are presented in horizontal rows, where each row represents a single record. The attributes of the features in the table are listed in vertical columns, with field names at the top.
So from geographical point of view a single vehicle (or a flock of birds) is a non-geographical feature. A compass and a scale bar on a map are just a map decorations and may not be considered as geographical or non-geographical features because they are not a real world objects.
GIS applications include both hardware and software systems. These applications may include cartographic data, photographic data, digital data, or data in spreadsheets. Cartographic data are already in map form, and may include such information as the location of rivers, roads, hills, and valleys.
(ˌnɒnˈspeɪʃəl ) adjective. not involving space. combining spatial information with non-spatial information such as facts and figures.
The spatial information and the attribute information for these models are linked via a simple identification number that is given to each feature in a map. Three fundamental vector types exist in geographic information systems (GISs): points, lines, and polygons (Figure 4.8 "Points, Lines, and Polygons"). Points.
Types of spatial patterns represented on maps include absolute and relative distance and direction, clustering, dispersal, and elevation.
Geographic Information Systems (GIS) in Public Health
The most common method of collecting spatial data is the use of global positioning system (GPS) receivers.
Spatial describes how objects fit together in space, either among the planets or down here on earth. There's a spatial relationship between Mars and Venus, as well as between the rose bushes in the backyard.
Examples would be schools, points of interest, bridge and culvert locations. Point features are also used to represent abstract points. For instance, point locations could represent city locations or place names. In GIS, point data can be used to show the geographic location of cities.
Generally speaking, Spatial data represents the location, size and shape of an object on earth surface such as mountain, plain, township, people etc. it also provides all the attributes of an entity that is being represented. Non Spatial data cannot be related to a location on the earth surface.
Meaning of non-spatial in English
not relating to the position, area, and size of things: The nonspatial attributes of an object include colour, temperature, and weight.
Examples of non-spatial data are names, phone numbers, area, postal code, rainfall, population, etc.
Non-spatial measure. describes and compares the masses of objects.
A spatial-to-non spatial dimension is a dimension whose primitive-level data are spatial but whose generalization, starting at a certain high level, becomes non spatial.
Spatial has broader meaning, encompassing the term geographic. Geographic data can be defined as a class of spatial data in which the frame is the surface and/or near-surface of the Earth. 'Geographic' is the right word for graphic presentation (e.g., maps) of features and phenomena on or near the Earth's surface.
