  1. Why collect GPS data How are we going To find this trap???

  2. GPS Applications • Ground applications • Obtaining latitude and longitude • Marking waypoints • Establishing routes, trails, etc • Finding sites • Permanent storage of locational data

  3. GPS Applications • Back in the office • Retrieving latitude and longitude info • Retrieving associated attribute data from field notes • Integration with GIS • Providing spatial relationships of attribute data • Providing base map imagery with site locations identified

  4. Find exact locations visited in the past Trap locations • Find traps • Find structures • Find anything, • Again, and again • And again.

  5. Route establishment – map a trail to and from work sites Work related! • Re-visit remote locations • Find your way back home

  6. Collecting GPS info – Initialization, and Setup • Initialize GPS units once • at beginning of each • season

  7. Collecting GPS info – Initialization, and Setup • Initialize GPS units once • At beginning of each • Season • GPS setup includes using • the correct datum • (NAD83, AK ZONE1)

  8. Collecting GPS info – Initialization, and Setup • Initialize GPS units once • At beginning of each • Season • GPS setup includes using • The correct datum • (NAD83, AK ZONE1) H&R will assist in the field with all setup procedures Refer to Appendix A

  9. Collecting GPS info – recording the necessary data Why? How? When? Where?

  10. Collecting GPS info – recording the necessary data Why? How? When? Where? Wp#143; confl. Rt bank; trapped 16 coho, 30 dv, 11 cutts in root Wad anchored to bank

  11. Collecting GPS info – recording the necessary data Why? How? When? Where? Fill in all required information on the H&R GPS Data Form

  12. Collecting GPS info – recording the necessary data Project:CWTLocation:Unuk River Comments:all waypoints are at upper 5 sites above Unuk base camp Observer:Dean Smith, Catfish Hunter, Sting GPS Datum:NAD83 GPS unit:Garmin 76 Site Name:shotgun slough-upper Date:5/20/2002 Waypoint #:145Error:31’ Latitude:56.23981Longitude:-132.55329 Comments:#145 is associated with large debris Jam centered on upper portion of shotgun slough – 10 traps are spread w/in 40 m of waypoint Why? How? When? Where?

  13. Collecting GPS info – recording the necessary data Trap locations Why? How? When? Where?

  14. Collecting GPS info – recording the necessary data Trap locations Why? How? When? Where? Unique habitat features Barrier??????

  15. Collecting GPS info – recording the necessary data Why? How? When? Where?

  16. Collecting GPS info – recording the necessary data Why? How? When? Where?

  17. Collecting GPS info – recording the necessary data Why? How? When? Where?

  18. Collecting GPS info – recording the necessary data Why? How? When? Where? Anywhere that is meaningful – Just provide the necessary notes!

  19. Applications of geo-referenced data • Integration with GIS • Base map with study reaches delineated • Spatial analyses • Distribution patterns The big picture: • Watershed characteristics with infinite # of attributes (habitat, fish,structures, photos, drainage, etc.)

  20. Start with base imagery (USFS ortho quads)

  21. Add additional coverages (streams, lakes, roads, etc)

  22. Pull in GPS waypoints

  23. Identify waypoints by unique values (species, number, structures, etc)

  24. Overlay unique values (> 1 species)

  25. Complete picture of species distribution in a watershed

  26. Application on the Unuk River • Add a spatial component to Sportfish projects • Begin with Base map imagery (8,000 ft ortho photos) • Update imagery with Remote Sensing techniques • (3-4000 ft low elevation digital photography) • Identify all CWT sampling sites by species • Identify pool habitat features in conjunction with CWT, Spawning ground surveys, mark-recapture and telemetry locations • Produce photo cards for use in classifying pool habitat features in new areas

  27. Application on the Unuk River Begin w/ coarse scale imagery

  28. Application on the Unuk River Pull in GPS waypoints

  29. Application on the Unuk River Zoom in and identify sampling sites

  30. Pool habitat classification – photo cards • Main channel – Key LWD, off shore • Location on mainstem associated with key pieces of LWD; has the following criteria: • Associated with mainstem channel • LWD is comprised primarily of 1 piece (tree, rootwad, stump) • LWD is anchored to shore • Substrate can be variable but mostly with smaller sizes (fines, gravel, pebble and cobble), especially on downstream side of LWD

  31. Pool habitat classification – photo cards • Off channel – LWD • Accumulation • Location off mainstem • With the following criteria: • Debris primarily associated • with side channel or off-channel Habitat. • Accumulation is comprised of • numerous pieces of LWD of • varying sizes. • May be anchored to sand bars • or banks of side channel
