What is spatial and non-spatial data?
1. MODULE 1: INTRODUCTION AND DATA STRUCTURE Spatial vs. Non-spatial Data Spatial Data Data that define a location. These are in the form of graphic primitives that are usually either points, lines, polygons or pixels.
What is geospatial data?
Geospatial data typically involves large sets of spatial data gleaned from many diverse sources in varying formats and can include information such as census data, satellite imagery, weather data, cell phone data, drawn images and social media data.
What are non-spatial attribute data attributes?
2.2 Non-spatial Attribute Data Attributes are the non-spatial characteristics that describe spatial objects. Attributes are commonly arranged in tables were a row is equivalent to one entity and a column is equivalent to one attribute, or descriptor, of that entity. Typically, each row relates to a single object and a geospatial data model.
What is the meaning of nonspatial memory?
Definition of nonspatial : not spatial: such as a : not relating to, occupying, or having the character of space nonspatial data b : not relating to or involved in the perception of relationships (as of objects) in space Hippocampal lesions … impair performance on a variety of spatial and nonspatial memory tasks.
What do you mean by non-spatial data?
Non-spatial data (also called attribute or characteristic data) is that information which is independent of all geometric considerations. For example, a person's height, mass, and age are non-spatial data because they are independent of the person's location.
Which of these is an example of Nonspatial data?
Some examples of non-spatial data could be: Lists of reference values (such as Country codes or equipment manufacturers). Postal addresses. Aggregated features such as National Roads which store the road name and reference a set of spatial road segments.
What is spatial data example?
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.
What are the 4 types of non-spatial data?
There are four typical data types that we use in GIS: integer, float/real, text/string, and date.
What is difference between spatial and Nonspatial data?
What is the difference? 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.
What is non-spatial data how is it used in GIS?
Non-spatial data may be joined to geocoded files with matching attributes and displayed as regular maps. This is common in Geographic Information Systems (GIS). For example census information such as race or income, non-inherently spatial data, can be displayed as maps.
What spatial data means?
Spatial data is any data with a direct or indirect reference to a specific location or geographical area. Spatial data is often referred to as geospatial data or geographic information.
What are the three types of spatial data?
In these GIS fields, the spatial data becomes much more complex and difficult to use. In addition to raster and vector data, there is also LiDAR data (also known as point clouds) and 3D data.
What are the 2 spatial data?
The two primary spatial data types are Geometric and Geographic data. Geographic data is data that can be mapped to a sphere (the sphere in question is usually planet earth). Geographic data typically refers to longitude and latitude related to the location of an object on earth.
What are the two types of non spatial data in GIS?
In the GIS world, there are two primary data formats one is a vector, and another one is raster data formats.
What are the four types of GIS data?
Polygons (properties), lines (streets), points (trees) and raster images (air photo) are separate layers integrated into one map.
Is population a non spatial data?
Examples of non-spatial data are names, phone numbers, area, postal code, rainfall, population, etc.
What are some examples of raster data?
Raster data is stored as a grid of values which are rendered on a map as pixels. Each pixel value represents an area on the Earth's surface....Some examples of continuous rasters include:Precipitation maps.Maps of tree height derived from LiDAR data.Elevation values for a region.
Which of the following are examples of vector data?
Vector data is represented as a collection of simple geometric objects such as points, lines, polygons, arcs, circles, etc. For example, a city may be represented by a point, a road may be represented by a collection of lines, and a state may be represented as a polygon.
Which one of the following is an example of raster data?
An example of discrete raster data is population density. Continuous data examples are temperature and elevation measurements. There are also three types of raster datasets: thematic data, spectral data, and pictures (imagery).
What are the 2 spatial data?
The two primary spatial data types are Geometric and Geographic data. Geographic data is data that can be mapped to a sphere (the sphere in question is usually planet earth). Geographic data typically refers to longitude and latitude related to the location of an object on earth.
What is nominal attribute data?
A nominal attribute data provides descriptive information about the object such as the color of the object, the name of an object so for instance a city name, or the type of an object. What’s important here is that this descriptive information does not imply any order, size, or any other quantitative information.
What is interval attribute?
The third entry category is interval attribute data. Interval attributes imply a rank order and magnitude or scale. Interval attributes use numbers, however, those numbers do not have a natural zero, and use an arbitrary zero point instead. For instance if we look at temperature on the Fahrenheit scale, 0°F is not a natural zero point for temperature, it is a human defined zero point. Therefore, while we can say that 50°F is 10°F more than 40°F, we cannot say that 50°F is twice as hot as 25°F, again, because 0°F is a human created zero, and not a natural phenomenon. With an interval attribute, addition and subtraction to make sense but not multiplication since values are relative from that arbitrary zero.
What is attribute table?
Attributes are the non-spatial characteristics that describe spatial objects. Attributes are commonly arranged in tables were a row is equivalent to one entity and a column is equivalent to one attribute, or descriptor, of that entity. Typically, each row relates to a single object and a geospatial data model. Typically, each object will have multiple attributes that describe the object, usually in what is called an attribute table.
How many attributes are there in a data set?
The data set we are looking at contains four objects, and each one of those objects represents a tree. Each object has four attributes showing in the attribute table: ID, height in feet, type, and class.
What is a float number?
The float, or real, data type holds a decimal number such as the number 1.452, the number 254,783.1, or -845.157. Like the integer data type, the float or real data type can be used for mathematical calculations. No rounding or truncation will take place when using float or real numbers, depending on the number of significant digits you have specified.
What are the four types of data in GIS?
There are four typical data types that we use in GIS: integer, float / real, text / string, and date.
What is the only measurement that uses a natural zero?
In terms of temperature, the only measurement that uses a natural zero is Kelvin, which has absolute zero. At that point, molecular movement ceases to exist.
Non-Geospatial Data
On your hunt for data, you may find that the data you are looking for does not exist in a GIS-ready format, such as a shapefile. Don't despair! There is a lot of other data out there that can be geocoded or linked to geospatial files. For example, this is often how people map census data - linking the data with census boundary files.
Canadian Cartographic Boundary Files
Cartographic Boundary Files are a series of products containing the boundaries of standard geographic areas together with the shoreline around Canada and larger inland lakes, all integrated in a single layer.

Why is FME important in GIS?
While there are many tools and software that can help you make use of spatial data, FME is the software of choice for those that need to integrate their spatial data. Safe Software and FME came into existence because of this exact problem. Spatial data varies widely and is often stuck in formats that cannot be easily used by all applications, making it extremely difficult for GIS experts to make use of all the information they have. While it was possible to transform proprietary formats in the past, much of the data would be lost in the conversion. Thus, FME was born.
How are geocoding and georeferencing different?
Georeferencing and geocoding are different but similar processes since both involve fitting data to the appropriate coordinates of the real world. Georeferencing is the process of assigning coordinates to vectors or rasters so they can be oriented accurately on a model of the Earth’s surface.
What is GIS field?
It consists of a variety of categories including spatial analysis, remote sensing, and geovisualization. In these GIS fields, the spatial data becomes much more complex and difficult to use. In addition to raster and vector data, ...
What is a raster in physics?
Rasters typically refer to imagery. However, in the spatial world, this may specifically refer to orthoimagery which are photos taken from satellites or other aerial devices.
Why is FME continuously upgraded?
FME is continuously upgraded to ensure it has been adapted to support new data formats, updated versions of data formats, and large amounts of data. Gone is the idea that individual departments must work in their data silos, with IT structures limiting the company’s potential to truly work as one.
What is spatial data?
Spatial data contains more information than just a location on the surface of the Earth. 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.
How is spatial data processed?
The most common way that spatial data is processed and analyzed is using a GIS, or, geographic information system. These are programs or a combination of programs that work together to help users make sense of their spatial data. This includes management, manipulation and customization, analysis, and creating visual displays.
What are the two types of geospatial data?

What is GIS in science?
Geospatial information systems (GIS) relate specifically to the physical mapping of data within a visual representation. For example, when a hurricane map (which shows location and time) is overlaid with another layer showing potential areas for lightning strikes, you’re seeing GIS in action.
What is geospatial data?
Geospatial data is information that describes objects, events or other features with a location on or near the surface of the earth. Geospatial data typically combines location information (usually coordinates on the earth) and attribute information (the characteristics of the object, event or phenomena concerned) with temporal information (the time or life span at which the location and attributes exist). The location provided may be static in the short term (for example, the location of a piece of equipment, an earthquake event, children living in poverty) or dynamic (for example, a moving vehicle or pedestrian, the spread of an infectious disease).
What is raster data?
Raster data is pixelated or gridded cells which are identified according to row and column. Raster data creates imagery that’s substantially more complex, such as photographs and satellite images.
What is vector and attribute?
