Introduction
This Spatial analysis refers to ask/answer
Presented by: Ed
questions about spatial relationships using a GIS.
i b i l l i hi i GIS
The merger of location and attribute data results in a spatial database that has the
capability to answer three basic questions: where is it; what is it; and what is next to it
The where of the spatial database
is the specific location represented The what refers to descriptions--or
through a system of coordinates The what is next to it of the
attributes--of features in the site, spatial database

listing technical criteria
Theme Criteria Purpose
Transport Proximity to rail network The closer the expressway is built to an existing rail network, the better the
future intermodality.
Current Traffic density Spatial benefit The higher the current traffic density, the more is the
reason to upgrade the road.
Ecology Protection of natural areas Spatial constraint National parks, Landscape parks, and national reserves
Wetlands, W t
W tl d Water courses, and lakes

Social and Safety Urban areas Spatial benefit The closer the route is to an urban area, the greater the
social convenience.
Spatial Cost The closer the route is to an urban area, the greater are the
incidences.
Population served Spatial benefit  the higher the population served, the more is the reason
to upgrade the road.
Economy Economic zones Spatial benefit  the more the economic activity in the area, the
more is the reason to upgrade the road.
Problem soils for construction Spatial cost  soils are prone to differential settlement and pose a
potentially high construction cost and/or high maintenance cost.
Cost of mitigation should be accounted for.
