Transcript of Introduction to GIS.
GIS is :
Applied problem solving methodology.
Health and Human Services
Four components of GIS
For utility and communication companies, GIS provides a common platform to access business data, manage assets, update network information, integrate work orders, find customer information, and prepare reports.
Natural resource managers rely on the analytical power of GIS for help in making critical decisions how manage the earth's resources.
Public health organizations rely on GIS to help in making decisions that influence population health. With powerful analysis tools and integrated workforce solutions, organizations can better grasp community health needs and design effective interventions.
A map contains a set of layers for a common geographic area
All elements in the map layer have a specific geographic location
One method for describing the position of a geographic location on the earth's surface is using spherical measures of latitude and longitude.
An address is a collection of information, presented in a mostly fixed format, used for describing the location of a building, apartment, or other structure or a plot of land, generally using political boundaries and street names as references, along with other identifiers such as house or apartment numbers
as a result of user manipulation and interaction with spatial data.
GIS links spatial and tabular data and
enables the user to perform spatial analysis,
Today, law enforcement agencies face new tasks and challenges. To address these ever-expanding responsibilities, GIS can help leverage the massive amounts of location-based data collected each day to create actionable intelligence you can use and share.
GIS for Transportation has been used for diverse purposes:
Modeling travel demand 20 years in the future
Tracking a snowplow
Analyzing the annual capital improvement plans
Identifying noise regulation violations around airports
Improving transit service throughout rejuvenated urban centers
Planning scenic byways in recreational areas
Business owners by merging demographic and business data, detailed maps, advanced spatial analytics, and their own data, they can make more accurate decisions about business operations, including how best to engage customers and create a more profitable marketplace.

Geographic information systems allow us to do things with digital representations that we were never able to do with paper maps
measure accurately and quickly
overlay and combine multiple layers of data
change scale, zoom, and pan without respect to map sheet boundaries
A SYSTEM OF HARDWARE, SOFTWARE AND PROCEDURES TO FACILITATE THE MANAGEMENT,
MANIPULATION, ANALYSIS, MODELING, AND DISPLAY OF THE GEOREFERENCED DATA TO SOLVE COMPLEX PROBLEMS REGARDING PLANNING AND MANAGEMENT OF RESOURCES.
UTILIZE GIS SOFTWARE
DATA + LOCATION = GEOSPATIAL DATA
Place or location is essential in GIS. It is a base for benefits of GIS. It enables to map and link different types of information because they refer to the same place, measure distances and areas.

Geographic Information Systems
What GIS does
Colors, symbols, and labels represent features found on the ground.
Provides information on the existence, location of,
and distance between ground features, such as populated places and
routes of travel and communication. It also indicates variations in terrain,
heights of natural features, and extent of vegetation cover.
A map is a visual representation of an area.
Map making technology.
Attributes refer to descriptive information.
Geospatial data has two components
POWER OF GIS
GEOGRAPHIC INFORMATION SYSTEMS
It is a tool to manage, analyze and display spatial information on the computer
It helps to make a better decisions
WHAT GIS IS
Geocoding is the process of finding associated geographic coordinates
(often expressed as latitude and longitude) from other geographic data, such as
street addresses, or ZIP codes (postal codes). With geographic coordinates the
features can be mapped and entered into Geographic Information Systems,
or the coordinates can be embedded into media such as digital photographs via geotagging.
Reverse geocoding is the opposite: finding an associated textual location
such as a street address, from geographic coordinates.

Geospatial data is the information that identifies the geographic location and characteristics
of natural or constructed features and boundaries on the earth
118th Boston Marathon
Boston Marathon, New England’s largest sporting event
Thirty-six thousand (36,000) registered runners
26.2 mile course
8 communities ( starts in Hopkinton and passes through Ashland, Framingham, Natick, Wellesley,
Newton and Brookline before reaching the finish line on Boylston Street in Boston)
On April 21st, emergency operations centers (EOCs) and/or command posts
(CPs) were operational in all eight cities and towns that host the Marathon. Additionally, a number of agencies stood up tactical operations/coordination centers, including;
MBTA Transit Police Department
Massachusetts National Guard (MANG)
Massachusetts Department of Public Health (MDPH)
Boston Medical Intelligence Center
Federal Emergency Management Agency (FEMA)
Boston Police Department, Boston Fire Department
Boston Emergency Medical Services
A Multi-Agency Coordination Center (
) connected all of these EOCs, command posts and operations/coordination centers to provide public safety coordination and resource support across the eight cities and towns that host the Marathon.
COMMON OPERATING PICTURE
Chip Mat (11 mats located every 5k and one at 13.1 mile)
Runners live feed was crated in collaboration between
BAA (Boston Athletic Association) and ESRI.
3 leading cars
1 tail cars
We used Collector Application in order to track locations of the Mass State Police vehicles escorting the lead male runner, lead female runner and lead wheelchair participant, and the location of the tail vehicle. The data was available in real-time on interactive Web Mapping Application.
Medical Stations Status
(how many individuals has been transported)
Shelters Status (Open, Closed and Full)
Operational Dashboard was design to provide Executive staff with comprehensive Common Operating Picture
