Geographic Information System

Geographic Information System with a spatial component for capturing, managing, analyzing and understanding information A set of software, hardware and data

Geographic Information System A GIS integrates hardware, software and data to capture, manage, with a spatial component for capturing, managing, analyzing and understanding information analyze and visualize any kind of information with a geographic component. A set of software, hardware and data

Three perspectives Map Data Models

The Data A single data repository: the Geodatabase Every geographic dataset, business logic and behavior

The Map A set of geometric features that represents a geographic reality. A window for exploring the data.

The Model Analysis tools that creates new geographic information from existing data.

In short, a GIS is An information system (hardware, software, data) which enables us to apply lots of analysis models to any geographical datasets for generating derived information that can be visualized as maps. A Geographic Information System helps us understand our world, answer questions about our environment and support us during decision-making.

Topology Branch of mathematics that studies geometry from a qualitative perspective. Topology describes the geometric relationships of a given space. A topologist is someone that can t distinguish between a cup of coffe and a doughnut Data

Topology in our GIS Defines the way different point, line or polygon layers relate each other geometrically. Two contour lines can t intersect Two parcels can t overlap Buildings must be within parcels Data

Behavior in our GIS Geometric features may have properties that represent geographic objects. Street network (edges, junctions, turns, impedances) Cadaster (parcels, boundaries, nodes ) Data

A GIS is An information system (hardware, software, data) that allows us to apply lots of analysis models to any set of geographic data in order to generate derived information that can be explored as a map.

Geographic Information Systems help us understand reality answer questions about our world and support us during decission-making.
