    • GPS/GIS 4-H:USING THE GLOBAL POSITIONINGSYSTEM IN 4-H PROGRAMMING
    • But we are going to start by goingOld School for a just a little while
    • GEAR-TECH-21 Camp 1.0 Activity Reading a Paper Map
    • Let’s take a look at thosemaps you created whenyou first came in today….. Draw a Map of Where you Are.
    • Reading a Paper Map• What kinds of Maps are there?• Did you use any symbols?• Did you draw things to scale?• Is your map small scale or large scale?• What was the purpose of your map?
    • Now let’s take a look at avariety of commercialmaps created for manydifferent purposes… What do they have in common?
    • Maps are not all created equalMaps for your own purpose can suit your needs…..butwhen you are communicating with a larger audience orpublishing it: – Maps need some basic components • A title • A North Arrow to indicate map orientation • Scale bar to measure distance • Source discloses the author and data source • Legend describes meaning of symbols and colors • Labels have names for geographic features • Geographic features represented by colors, drawings or symbols
    • There are basically 2 kinds of maps• General reference maps – Color or other symbols are typically related to physical geographic objects familiar to the public such as roads, river and cities• Thematic Maps – Have key information is related to information associated with given property or data layer ..they represent a specific theme such as land ownership..with private and public lands in different colors or population density
    • GEAR-TECH-21 Camp 1.0 Activity Direction
    • Direction• Direction is Relative• Equator-Divides North and South• Prime Meridian-Divides East and West• Heading• Bearing• The Basic Direction Device – the Magnetic Compass
    • The Magnetic Compass• The Parts
    • How have you encountered GPS and GIS Mapping?
    • GPS and GIS Mapping aredaily encounters for many…• Smart Phone Apps depend on GPS and display GIS Mapping• In our autos• While out Fishing or Hunting• While out Farming• While out Hiking• Just for fun or adventure-Geocaching and Earthcaching
    • SOME GPS APPLICATIONS COMMERCE & RECREATIONAL GOVERNMENT • HIKING• MILITARY • HUNTING• MARITIME • NATURE STUDY• AUTOMOTIVE • FISHING• SURVEYING • BOATING• AVIATION • BIKING• FORESTRY • SKIING• ENVIRONMENTAL • SNOWMOBILING• PUBLIC SAFETY • GEOCACHING• ETC. • GOLF ! ETC.
    • HOW CAN WE UTILIZE GPS IN 4-H PROGRAMMING? EDUCATIONAL & OPERATIONAL USESWILDLIFE MAPPING HIGH ADVENTURE LEADER TRAINING SEARCH & RESCUE BIG TREE SCIENCE & TECHNOLOGY SEARCHHUNTER EDUCATION TRIP PLANNING & SAFETY ENVIRONMENTAL FISHING & CANOEING EDUCATION AND LOTS MORE !
    • Global Positioning SystemA network of satellites that continuously transmit coded information, which makes it possible to precisely identify locations on earth by measuring distance from the satellites. THE GPS SATELLITE CONSTELLATION From GPS Land Navigation by Michael Ferguson
    • GPS and GIS DEFINITIONSGPS is short for Global Positioning System which is"a network of satellites that continuously transmit codedinformation, which makes it possible to precisely identifylocations on earth by measuring distance from the satellites".Of course, many users also refer to their hand-held GPSreceivers as "my GPS" ... as in the statement "my GPSbatteries went dead and I got lost!"GIS is short for Geographic Information System(s). "In thestrictest sense, a GIS is a computer system capable ofassembling, storing, manipulating, and displaying geographicallyreferenced information , i.e. data identified according to theirlocations. Practitioners also regard the total GIS as includingoperating personnel and the data that go into the system"( from: http://www.usgs.gov/research/gis/title.html ).

    • Let’s Get our Hands on GPS!• Each of you will get a Yellow Garmin E- Trex to work with

    • Trilaterion and Space• Trilateration Activity UP and GOING• Trilateration Activity with a boy lost
    • Lets go set some waypoints!• Each team set five waypoints and then exchange a GPS unit with another team• See if they can find the each of your waypoints• Each team will stash one Geocache and then share exchange GPS units with another team to see if you can find theirs• Collect a ping pong ball from each
    • We’re Back…..• Let’s put that data to good use• Import your waypoints into Easy GPS
    • M OThe 411 for 911 S.U.M.O Community Service Project 2011 “WE SAVE LIVES”
    • THE PROBLEM:• When firefighters go out on an emergency call they might have trouble finding the exact location of the fire hydrant.
    • THE SOLUTION:• Our IT team mapped out the location of fire hydrants in the communities of Missouri Valley, Magnolia, and Pisgah using GPS units.• This allows Firefighters to access the hydrants quickly and put out fires more effectively. In retrospect…. “WE SAVE LIVES.”
    • THE PROCESS: The GPS Unit• We got in contact with the head of the Harrison County GIS, Jeremy Butrick.• He provided us two of these units and he trained us on how GPS works and how to use these units for accuracy and gave us assistance with his software to import the waypoints and transfer them to a GIS map that Harrison County Emergency Services would use in guiding firemen to the closest hydrants.
    • How it Works:• There are always many satellites in motion above our heads.• A maximum of 13 satellites at any given time are within range to communicate with our device, but only 4-5 are needed to record its location.• At the push of a button, this device uses those satellites to mark its position.• Due to cloud coverage, wind, sound wave reflection, and blockage from objects, the reading given by one of these units can be off by up to 6 feet. To counter this, the GPS unit takes a minimum of 20 readings, about one a second, to get an accurate average.
    • How We Did It:• We picked two days that would have the best satellite coverage for our big town, Missouri Valley and our two small towns, Pisgah and Magnolia.• We went around finding all of the fire hydrants and recording their locations.
    • • Jeremy took the GPS Units and hooked them up to his computer.• The computer took the points we recorded and averaged every point out.• The points were then put on to pre-existing GIS maps of the towns for Harrison County Emergency Services and the 911 Center to use in helping firefighters know where the closet hydrants are to a location.
