Location Intelligence, Location Analytics, Geo Spatial Analysis, etc

Location Intelligence combines geographic data and business data together to uncover trends and patterns. Typically I refer to Location Intelligence as the end result, insights, or new information created from the process. Location Analytics essentially means the same thing, though typically analytics entails processing and calculating geo-spatial analysis.
IMPORTANT TIP: Location Intelligence does NOT EQUAL Maps. Location Intelligence is the process and outcome. In most cases the end result of Location Intelligence is displayed visually in a map. Seperating Location Intelligence from mapping will help your learning process.

Maps and “Basemaps”

The modern digital map, comes in many different forms and styles from a number of software vendors. Google Maps helped commoditize the geographic map, along with GPS systems prominent in our automobiles.  When you hear the word “basemap” this typically refers to the map for which visualization is drawn on top. Google Maps, ESRI, OpenStreetMaps, HERE (formerly Nokia), and Bing are the most popular base maps used today.

(GIS) Geographic Information System

GIS is a system designed to create, store, manipulate, and visually present geographic data. GIS systems usually include a database, middleware, and/or client tools for end to end creation, integration, and analysis of geospatial data.


Individual locations on a map often visually represented as an icon. A point can be referenced in a map using one of multiple references whether it be an address, latitude,longitude, x/y coordinates, or even a city name. The definition and precision of a point can vary based on what mapping technology you are using and how the point is defined.

Latitute, Longitude

Latitude and longitude is a geographic coordinate system to represent locations on a map. Most modern mapping software and devices use a “Decimal degree” coordinate system or latitude and longitude (ex: 34.00023, -122,49923) which can also include a third value for elevation in some software packages.


Is the process of transforming geographic data like addresses, cities, or states into geographic coordinates like latitude/longitude. The benefit of geocoding data is having a machine readable format to quickly query and display.


A polygon is an enclosed shape that can be used to represent an area on a map. A polygon in business terms could be used to represent a country, state, zip, or even custom region. Polygons are made up of individual latitude/longitude points that when combined, define the bounds of a polygon.


Is a contiguous line used to represent linear assets on a map. A polyline in business terms could be used to represent a railroad, power line, waterway, or even as a pure graphical element to represent relationships between elements.

Heat maps

A heat map is a visual representation of space using color intensity to represent numeric value. A heat map can be represented as points, polygons, or even lines.

Density Maps

Is a data visualization technique that uses the overlapping locations, combined with an algorithm that changes the color intensity and/or hue of the visualization as points overlap and intersect.


A route is a path between two or more locations on a map. Routes can be represented in different ways depending on the travel mechanism. For example, driving, walking, or flying from point A to point B could be drastically different.

Advanced Terms

Spatial Data Type

Spatial data types allow database administrators to describe data for its intended use in applications that would query this data. For example, latitude/longitude, polygons, and even polylines are spatial data types supported in GIS databases, along with SQL, Oracle and TeraData. Otherwise spatial data stored in a database that does not support spatial or geospatial data types would be stored as traditional database field types like TEXT. The value of spatial data types is the optimization for indexing and serving up this data, specifically when spatial queries are required.

Raster Map

A raster map is a map made up of pixelated images or photographs, and often stitched together . Google Maps and Bing Maps are common raster maps that are built up with tile images. Satellite imagery is an example of raster imagery and the best use case for these map types.

Vector Map

A vector map uses mathematical vectors to draw map imagery rather than photographs. Vector maps require raw data and algorithms to draw and animate graphics on a screen and gain the benefits of resolution independence  Vector graphics are best for drawing organic shapes where less detail is required.


A centroid is the center of a polygon, often used by applications to use a single point of reference for an entire area (polygon).


Is a process for identifying individual points that cross the threshold of a polygon or polyline or that already exist inside or outside of a polygon.


Is the physical space surrounding an individual location. This space is the radius, typically measured in miles or kilometers.

Bounding Box

Bounding box is a rectangular space within which points lie. The entire map viewing area could be considered a bounding box, but a bounding box could also be used to select and further restrict a view within the map control.

Geodetic datum

Is a method to translate location to actual position on earth, which important because the earth is not a perfect sphere. WGS 84 is a global datum used by all GPS vendors and is supported for use with most digital mapping technologies like Google Maps.

Geo-Spatial Query

A Geo-spatial query is a type of spatial query that takes into account the attributes of the earth’s spherical shape to return data. Geo-spatial queries are used with databases or data-stores that support spatial data types and allow for operations that are designed to take into account the attributes of spatial data. For example, a spatial query could simply request locations within 5 miles of a single location. More sophisticated spatial queries could request locations that are at least 5 miles away from each other (commonly referred to as a buffer). Spatial queries are optimized for use with spatial data. GIS systems were traditionally specialized systems for spatial data and queries which has changed in recent years as database vendors like Microsoft, Oracle, IBM and other add support for spatial queries.

Spatial Data Formats



A shapefile is a binary file format that stores spatial data in a highly compressed format. It is used to transmit vector data from GIS systems like ESRI and other systems. A shapefile typically requires 3 files (4 if you need to re-project the data for use with tools like Google Maps). The .SHP, .DBF, and SHX are critical files that will travel together and can be edited in GIS tools like ESRI or open source GIS tools like Quantum GIS.
DBF File- A Database file holds all of the meta data that describes each node (point, polygon, line segment, etc) inside of the Shapefile. These DBF files can be opened inside of Excel.
SHX file– The SHX file contains meta data required to combine the DBF and Shapefile together.
PRJ File– The projection file is important if you are unaware of the origination of your shapefile. It identifies what projection (related to geodetic datum) was used and is typically required if you need to change the projection for compatibility with web based mapping tools like Google Maps.


Web Map Service is a protocol for transmitting map imagery (raster map imagery) over the web from a GIS database. This map imagery can range from map tiles to demographic overlays, to weather patterns.


Keyhole Markup Language was acquired by Google and is an XML based definition for transmitting and storing geospatial data and meta data related to points, polygons, polylines, and other geospatial data types. Do you have more terms that should be on the list? Let us know.
