1. GIS in Water Resources (CIVE 853) Fall 2017
Introduction to ArcGIS Software
Instructor: Dr. Ayse Kilic
Civil Engineering and School of Natural Resources
University of Nebraska

2. History of GIS
Advent of computer in late 50’s, early 60’s—computerized mapping programs, but NOT “GIS”.
No attribute data.

3. Environmental Systems Research Institute (ESRI)
ESRI)founded in 1969—grew from research group at Harvard.
Current vector-based (arcs/nodes) ArcGIS software an outgrowth of this research.

4. ArcGIS System Create, share, and use intelligent maps

5. ArcGIS Key Features https://www.arcgis.com/ Spatial Analysis
Data Management
Mapping and Visualization
Advanced Editing
Geocoding
Map Projections
Advanced Imagery
Data Sharing
Customization

6. Spatial Analysis
Analytical tools and operations that can be applied to solve a very wide range of problems
Derive new information from your data in order to make better decisions by applying geographic, statistical, and mathematical operations to the mapped data

7. ArcGIS Online GIS on the web – online map services

8. Online Base Maps (20 scales)

9. Programming Automation of repetitive tasks (workflows)
Implementation of functionality not available (programming new behavior)

10. Summary
GIS offers a structured information model for working with geospatial data that describe the “water environment” (watersheds, streams, lakes, land use, ….)
Water resources also needs observations and modeling to describe “the water” (discharge, water quality, water level, precipitation)
Geography “brings things together” through georeferencing on the earth’s surface
Understanding geolocation on the earth and working with geospatial coordinate systems is fundamental to this field
GIS has traditionally been used on the desktop but increasingly there is a transition to information sharing on the web
