What is a GIS?

• Geographic Information System

• "a container of maps in digital form"

• "a computerized tool for solving geographic problems"

• "a tool for performing operations on geographic data that are too tedious or expensive or inaccurate if performed by hand"

What is a GIS?

USGS (United States Geological Survey):

In the strictest sense, a GIS is a computer system capable of assembling, storing, manipulating, and displaying geographically referenced information, i.e. data identified according to their locations.


What is a GIS?

(Earth Science Research Institute):

GIS is a system of computer software, hardware and data, and personal to help manipulate, analyze and present information that is tided to spatial data.


What is a GIS?

INHS (Illinois Natural History Survey):

It is an organized collection of computer hardware, software, geographic data, and personnel designed to capture, store, update, manipulate, analyze, and display all forms of geographically referenced information.

This system allows users to perform very difficult, time consuming, or otherwise impractical spatial analyses.

What is a GIS?

A computerized system dealing with

• collection,

• storage,

• manipulation,

• analysis,

• visualization

• displaying geographic, and geographic related information.


Major components of GIS


• Hardware

• Software

• Data

• People

• Procedure

• Network

Two basic types of data

• Geometric datadescribe the location of real world phenomena (earthquake, rainfall), features and objects (roads, parcels). It is concerned to a reference system.

• Attribute datadescribe relevant properties of real world phenomena, features and objects.


Geometric data


Earthquake events occurred over the last century

Attribute data


Yellow: shallow (-25) Red: intermediate (26-75) Black: deep (76-)

Layers


A layer is a collection of geographic entities of the same type.

Georeferencing and coordinate systems


All the elements in a map layer have a specific geographic location and extent that enables them to be located on or near the earth's surface.

Assigning map coordinates and spatial location.

Longitude - Latitude

Data modeling


A data model is a set of constructs for describing and representing selected aspects of the real-world in a computer.

GIS data models


• Real word artificial objects• Discrete objects

• Continuous fields

• Data storage• Vector

• Raster

The elevation of a geographic location is its height above a fixed reference point.

Vector-based models


+

Represent features as points, lines and polygons and describe its geographical data by vectors.

Raster-based model


cell

• The raster data model represents features as a matrix of cells in continuous space. • Each cell contains location coordinates and an attribute value, that is used to represent some characteristic of that location.• Raster coordinates are contained in the ordering of the matrix (implicitly).

Advantages and disadvantages


Raster Vector

Storage capacity larger less

Scaling, reprojecting easier

Number of algorithms less more

Conversion possible possible

Performing overlay op. easier

Visual experience better

Why Telecoms Need geoinformatics

• Telecoms have not historically used GIS, but its usage can imply a significant growth.

• Frequent questions to answer• Is a given building serviceable?

• What is the estimated cost of installing a new service?

• Is there a quote there available?

• Many work practices of telecommunications companies have spatial element.


Who uses GIS in Telecommunications?• GIS is now a standard technology applied throughout the

telecoms industry to

• plan

• build

• operate telecommunication networks and associated services.

• Independent telecommunications consultants use in-house GIS software to provide engineering and construction services.

• Research and educational institutions use GIS packages to teach network planning, operational and marketing skills.


Proprietary GIS software

•• ArcGIS

• online

•• Autodesk Map 3D

• Student licence (!)

• MapInfo

Case Studies

• Bell Aliant (Canada) - Telecommunications and Fiber Optics Service Provider

• SRP Telecom (USA) - Fiber Network Provider

• TDS Telecommunications Corporation (USA) – 7th largest local exchange telephone company


CS1 - Fiber-Optic Services to the Home in Less TimeBell Aliant (Canada) - Telecommunication and Fiber Optics Service Provider

• Started to offer fiber-optic services to more than 650,000 customers within three years.

• Sophisticated database for spatial information, accessed centrally.

• Operators brought real-time, accurate network views to stakeholders throughout the organization.

• “We contained costs and met our build schedule by automating tasks. We reduced engineering time by 32 percent and improved accuracy 25 percent.” – GIS manager


CS2 - Simplifying Fiber BackhaulConnectionSRP Telecom (USA) - Fiber Network Provider

• 1,600-route-mile fiber network can fulfill the needs of cellular companies looking to upgrade backhaul capacity

• They provide potential customers with an accurate cost estimate as well as a detailed map showing the network access location and proposed route.

• GIS helps them to determine the proximity of network access points to customer cell sites, helping it respond quickly and appropriately to any request for pricing.



• Process moved to paperless.

• Analysis can be completed with minimal trips to the field.

• Improved accuracy reduces risk.

CS3 – Cuts Week off EasementRetrievalTDS Telecommunications Corporation – 7th largestlocal exchange telephone company

• Provides more than 1.2 million residential and business connections to Internet, phone, and TV entertainment nationwide.

• Manual processes to comply with land-accessregulations time


TDS engineers access easement information directly from a web map. They can pull up information related to localized townships, ranges, and sections, thanks to a SharePoint integration with GIS technology.
