Geographic Information Systems GIS Fundamentals for Program Managers

Geographic Information Systems (GIS) Fundamentals for Program Managers 1

What is GIS? § A technology of hardware, software, data, people, and processes § A technology that connects intelligence to a place on the earth § The objective: to improve overall decision making 2

Geographic Information Systems GIS is an extremely effective tool for: § § § Decision Making Identifying trends and relationships Visualizing tabular data via maps Synthesizing Data Solving Problems Reports, Presentations, Trainings 3

How Can GIS Help My Customer? Rapid Eligibility Determination Data Supported Decisions Solid Demographic Analysis Strategic Planning 4

How Can GIS Help My Staff? Fast, Efficient Workload Accurate, Timely Process Data Visualization Accurate, Efficient Analysis Reliable, Automated Calculation 5

How can GIS help Government in General? Better solutions to business requirements Maximize benefits of taxpayer money Forecast outcomes Measure targeted performance Present powerful ideas quickly 6

GIS Formal Definition GIS is "an automated system for the capture, storage, retrieval, analysis, and display of spatial data. " (Clarke 1995) 7

GIS Components Hardware, software, applications, networks, telecommunications Data Methods People Standards Metadata Business goals, needs, logic, and processes, governance 8

What are Maps? Discovery imagination hypothesis description Location § size § shape § distance § direction § route 12 th Century map of the Mediterranean Analysis § § proximity relationship projection forecast 9

Two main types of GIS data § Raster Data § § Aerial imagerly (not geogreference) Orthophotography Satellite Imagery Topographic Vector Data § Points § Lilnes § Polygons Point Line Polygon 10

GIS Integrates All the Parts Program Data Demographics Administrative boundaries Transportation Water Areas and Hydrologic Units Topography and Soils Imagery 11

Common Access to Data 3 D features of Google Earth are suddenly commonplace to non-GIS users. Seen here is USDA and DC Southwest 23

Sensors and Location Sensor Web Wireless devices linking sensors, GPS, GIS, the Internet, databases and more. “Sensor Web is a special type of webcentric information system for collecting, modeling, storing, retrieving, sharing, manipulating, analyzing, and visualizing information of sensors, sensor observations, and associated phenomena. This new earth observation information system opens up a new avenue to fast assimilation of data from various sensors (both in situ and remote) and to accurate analysis and informed decision makings. ” Sensor Web @ Geo. ICT Interoperable devices Near real time data Wireless networks 24
