Manipulation of spatial data into various forms to be able to extract additional and meaningful information to understand the real world

Spatial Analysis

uses Boolean operators

Querying

can be combined to identify features that satisfy two or more spatial criterias

Querying

finds all map units that have both attributes specified

AND

finds all map units that have either one attribute or another attribute or both specified

finds all map units either one attribute or another attribute but not both attributes together

XOR

finds all map units that have one attribute but not another

NOT

Creation of a zone of interest around an entity

Proximity Analysis: Buffering

circular buffer zone

Point

elongated buffer zone

Line

same shape as buffer zone but larger

Polygon

A partitioning of the plane into polygons that have this characteristic, that is containing all the locations that are closer to the polygon’s ‘midpoint’ than to any other ‘midpoint

Proximity: Thiessen Polygon

New spatial data layer from two or more old data layers

Overlay Analysis

three types of overlay analysis

Line-in-polygon, Point-in-polygon, Polygon-on-polygon

used to find the polygon in which a point falls within, or find a point or points that fall within a certain polygon

Point-in-polygon

used to find the polygon in which a line or lines fall within, or find a line or lines that fall within a certain polygon

Line-in-polygon

•used to determine which polygons from two layers intersect or are within another polygon

Polygon-on-polygon

types of polygon-on-polygon

Union, Clip/Cookie-cutting, Intersect

•Boolean operator: AND

Intersect

•Boolean operator:NOT

Clip/Cookie-cutting

Corresponds to the Boolean operator: OR

Union

•Site Selection process
