2 GPS Receivers Hand-held unit “Digital compass” with a brain.
Receives latitude and longitude data Receives time data

3 GPS Receivers – Quality Levels
Survey grade Mapping grade Recreational grade <1 meter accuracy 1-2 meter accuracy 10-20 meter accuracy Recreation grade (10-20m) Mapping grade (1-2m) Survey grade (<1m) There are three common grades of receivers frequently used by GPS data collectors: survey grade, mapping grade, and recreational grade. Survey grade is the most accurate and is based on real-time kinematic GPS technology. A survey grade GPS unit is used in situations where accuracy is essential, such as engineering applications, property boundary determinations, and robotic vehicle guidance. Survey grade receivers typically can provide true positional accuracy within a centimeter in the horizontal direction and elevation accuracies within 10 centimeters. Mapping grade receivers are typically used where accuracy is important, but not worth the added expense of owning or leasing a survey grade receiver. Mapping grade receivers are differentially corrected GPS to reduce positional errors. Differentially corrected GPS systems are capable of horizontal accuracies from one to two meters, depending on the source for the real-time correction data. Vertical accuracy is typically 3 meters. Applications for mapping grade receivers include field scale surveys of wetland boundaries, mapping nutrient levels in agricultural fields, and crop yield monitoring. The least accurate GPS receivers are recreational grade, typically used for outdoor sports or navigation. These receivers do not use differential correction, and may have position error up to 20 meters. Test Material

Called GIS Includes GPS Unit Computer software Database information Satellites Control stations

5 Geographic Information System
geographic information systems (GIS) - are organized collections of computer hardware, software, geographic data, and personnel designed to efficiently capture, store, update, manipulate, analyze and display all forms of geographically referenced information. GIS is being used by many researchers in the environmental field to view a number of different indicators simultaneously as data layers on a geographic grid. By associating data of all kinds with points on a map, GIS can illustrate patterns and trends that might otherwise be incomprehensive. For example, using GIS, a researcher can map multiple health indicators at and around a specific toxic waste site.

6 ArcView Software GIS programs by ESRI
World leader in GIS software and data production Partnership with state of South Dakota Interactive mapping software Database information Retrieve public data Input end user data ESRI – world leader in GIS software and data production. When we began this company back in 1969, we felt an almost limitless enthusiasm for the possibilities of GIS. We understood even then that this new geographic information system technology could bring about a better future. Our confidence in GIS is built on the belief that geography matters. It fundamentally influences and connects our many cultures, societies, and ways of life. As you explore our Web site, you will find abundant evidence of the important contributions that GIS technology can make in improving our quality of life and supporting more analytical decision making. Our technology helps fight forest fires, determine new national boundaries during peace negotiations, find promising sites for fast-growing companies, rebuild cities around the world, support optimal land use planning, route emergency vehicles, monitor rain forest depletion, contain oil spills, and perform countless other vital tasks every day. GIS technology must constantly evolve to meet the changing needs of business, industry, government, and education. We are ready for these changes. Today, ESRI has more than 2,700 skilled employees worldwide who work with hundreds of business partners and tens of thousands of users. Each one makes a unique contribution to this remarkable technology. Each one makes a difference. Thank you for taking the time to learn about our company. We hope you enjoy your journey through our Web site. Come back and visit often to learn about exciting new uses for our software. We invite you to share your ideas with us by .

8 GPS/GIS Uses Military Emergency response Economic development
City planning Real Estate Recreation Military – missiles and night vision navigation Emergency response – On Star, Fire & ambulance Economic Development – possible site location City planning – infrastructure – electricity, water, sewage etc. Real estate – characteristics of houses, query for prospective buyers, bedrooms, roof type, yard size etc.

9 Why Teach GPS/GIS? Hands on learning Kids love to use technology
SDSU Geography majors Real world application Hands on learning – literally, kids go outside and navigate and record information into GPS Kids love to use technology – tech age SDSU Geography majors – recent graduates required to take courses in GIS Real world application – outdoor sports, car navigation, future job possibilities

10 GPS/GIS at WHS Attended GPS/GIS TTL summer 2003
Created a unit in World Geography course on GPS/GIS Attended GIS workshop spring 2004 in Pierre

11 GPS/GIS at WHS - Unit Covered background information
2 days GPS unit training 1 day of Ki-Yi Treasure Hunt 3 days of ArcView software training 3 days mapping our routes in WTN

1. use maps, globes, and other geographic tools to acquire, process, and report information from a spatial perspective by selecting appropriate maps, map projections, and other graphic representations to analyze geographic problems; constructing maps using fundamental cartographic principles including translating narratives about places and events into graphic representations; interpreting maps and other geographic tools through the analysis of case studies and using data; and using geographic tools to represent and interpret the earth’s physical and human systems.

13 Ki-Yi Unit Objectives:
After completing this unit the student will be able to understand… how to care and operate the handheld GPS units. the many real-world applications of GPS and GIS systems. how GPS/GIS have affected their world and possible uses for them in their future. how to correctly generate and use map projections of various types.

14 Ki-Yi Unit Tasks Hook – How GPS is used today. Military and civilian uses. Ambush in Iraq Laser Guided Missiles GPS Guided boat to Cuba Discuss misconceptions and current knowledge of GPS or GIS systems handout. View the website GPS Uses in Everyday Life – Aerospace Corporation GPS primer and complete worksheet. Go over Location Review document and website World Latitude and Longitude

15 Ki-Yi Unit Tasks GPS/GIS consumer uses Internet activity.
With the GPS unit in hand, read through the User Guide overview. Learn to set a waypoint and navigate to it. Enter ______________ as the goto point and determine what is at that location. Partner up and do Ki-Yi Treasure Hunt.
