Slide 3

Assumptions You regulate individuals or work in one/numerous parks in Alaska You need to record your field areas or guide existing base, trails Use to explore to/from Archive the areas in a later in a GIS You have entry to the great AKSO Intranet and the X:drive

Slide 4

What a GPS Mapping Receiver ought to do Hardware Software Support

Slide 5

What a GPS Mapping Receiver ought to do Hardware Accuracy (How near Truth) Meet National Mapping Accuracy Standards: 1:63,360 (32meters) 1:24,000 (12 meters) 1:5,000 (4 meters) Precise (How dependable) Rugged Able to Average a Point External Antenna alternatives Good on Batteries No Problem!

Slide 6

What a GPS Mapping Receiver ought to do Software Export in GIS Friendly Formats (shapes, inclusions) Capable of Controlling Attributes in the Field Data Dictionary (Name, Trail Width, Comments) Capable of Datum Transform Mission Planning Sky Plots Planning the day Run on standard PC/hardware

Slide 7

What a GPS Mapping Receiver ought to do Support (AKSO) Manufactured by Trimble, Garmin or Rockwell GIS Products that use ESRI - NPS Standard ArcView ArcInfo Ensure your information has long timeframe of realistic usability

Slide 8

Overview of Main Types Recreational Grade GPS - Garmin Mapping Grade GPS - Trimble Y-Code Receivers - Rockwell PLGR+96

Slide 9

Recreational Grade GPS - Garmin Features Include: Wide Use - Alaska National Parks/AKSO = 60 Accuracy: Autonomous < 15meters 95% commonplace DGPS prepared 3-5 meters 95% average User Friendly Many models Garmin GPSIII+, GPSMap76, eTrex Moving Base Maps (1:100,000 scale) Garmin

Slide 10

Mapping Grade GPS - Trimble Features Include: Wide Use - Nationally AKSO (dozen) Accuracy: Autonomous < 15meters 95% normal Post-Process DGPS 3-5 meters 95% run of the mill (Geo3) 1 meter 95% regular (ProXR) Pathfinder Office Software Data Dictionary, Mission Planning Trimble

Slide 11

Y-Code Receivers - PLGR+96 Features Include: Rugged Good under Canopy 999 Waypoint Storage EHE showed Datum Switch found in ASCII Out PLGR

Slide 12

GPS for GIS - Pros and Cons Garmin III+ Pros Cheap and predictable 15 meters positions - great under shelter Good "Point device" Fun and simple to utilize Integration into ArcView - moderately clear Battery utilization is incredible Cons Cheap Position precision not all that dependable Not intended for GIS Mapping - depends on outsider programming No Data Dictionary capacity Decent stockpiling of tracks/waypoints (6-10 hours)

Slide 13

GPS for GIS - Pros and Cons Trimble GeoExplorer 3 Pros 1-5 meter mapping apparatus Point/Line/Poly Rugged Collect for 16 hours Software is fabulous Cons $4000 Firmware will change? Under Canopy issues - must utilize reception apparatus No Data Dictionary Very little stockpiling of tracks/waypoints(999) Need to post-process after the field (web association)

Slide 14

GPS for GIS - Pros and Cons Trimble Pro XR Pros Top-of-the-line GIS Mapping Tool Real-time DGPS Point/Line/Poly Good under Canopy Rugged Software is incredible Cons $10,000 Big/Bulky Firmware will change Training included

Slide 15

GPS for GIS - Pros and Cons PLGR Pros Consistent 15 meters positions Familiarity (bugs worked out) Good "Point instrument" Rugged. Records blunder Integration into ArcView - generally direct Cons Older innovation Heavy Terrible on batteries Club Fed just No Data Dictionary capacity Very little stockpiling of tracks/waypoints(999)

Slide 16

Right Tool for the Right Job Sorry… It\'s a Multi - Tool Environment Garmin Trimble PLGR Need to learn enough about every framework to know when to utilize the instrument Mapping a junk can cover? - ProXR Mapping an ATV trail - Garmin, Geo3 or ProXR Mapping sheep from the air? - Garmin\PLGR Mapping complex properties? - Geo3 or ProXR In Dense Canopy - PLGR/ProXR

Slide 17

Ideal GPS Toolkits Garmin for route, point gathering Use DGPS framework just if working along Gulf of Alaska, Southeast, out on the water PLGR for thick individuals/thick covering For Serious GIS Trimble Geo3 for open nation mapping Trimble Pro XR for everything

Slide 18

What is Best? Ask Yourself 1) What are your exactness needs? A) determination of the other information sorts B) foreseen information for the future 2) Project Needs A) What are your GIS abilities B) Is it just you managing the information 3) What some portion of Alaska would you say you are working in? 4) How much cash do you have?
