Why collect GPS data

How are we goingTo find this trap???

GPS Applications

Ground applications

Obtaining latitude and longitude Marking waypoints Establishing routes, trails, etc Finding sites Permanent storage of locational data

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

Find exact locations visited in the past

Trap locations

Find trapsFind structuresFind anything, Again, and again And again.

Route establishment – map a trail to and from work sites

Work related!

Re-visit remote locations

Find your way back home

Collecting GPS info – Initialization, and Setup

Initialize GPS units once at beginning of each season

Collecting GPS info – Initialization, and Setup

Initialize GPS units once At beginning of each SeasonGPS setup includes using the correct datum (NAD83, AK ZONE1)

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.)

Start with base imagery (USFS ortho quads)

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

Pull in GPS waypoints

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

Overlay unique values (> 1 species)

Complete picture of species distribution in a watershed

Application on the Unuk River

Add a spatial component to Sportfish projectsBegin 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 speciesIdentify pool habitat features in conjunction with CWT, Spawning ground surveys, mark-recapture and telemetry locationsProduce photo cards for use in classifying pool habitat features in new areas

Application on the Unuk River

Begin w/ coarse scale imagery

Main channel – Key LWD, off shore

Location on mainstem associated with key pieces of LWD; has the following criteria:Associated with mainstem channelLWD 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

Pool habitat classification – photo cards

Off channel – LWDAccumulation

Location off mainstem With the following criteria:

•Debris primarily associatedwith side channel or off-channel Habitat.

•Accumulation is comprised ofnumerous pieces of LWD of varying sizes.

•May be anchored to sand barsor banks of side channel
