## Objective

**Select settings appropriate for each project**

**Before you go!**

**Notes:**
The key is to determine what is appropriate for each project because there is no one right or wrong way.  These slides will be modeling one set of parameters because we think that is the best for this class.  Remember there may be good reasons for making other choices in another situation.

**Notes:**
GPSMAP 76S Information Page
	The startup page displays the receiver’s status:
Auto Locate: the receiver is initializing and collecting or updating its almanac.
Acquiring Satellites: the receiver is collecting data from satellites, but doesn’t have enough information to calculate a position.
2D GPS Location: at least three satellites have been locked on to, but the receiver is only able to provide a two-dimensional position.
2D Differential Location: indicates that the receiver is using differential GPS or WAAS on only three satellites.
3D GPS Location : at least four satellites have been locked on to and the receiver is able to calculate a three-dimensional position.
3D Differential Location: indicates that the receiver is using differential GPS or WAAS on at least four satellites.
Lost Satellite Reception: the receiver is unable to calculate a 2D or 3D position due to lack of satellites.
Simulating GPS: the receiver can be used indoors, or where no satellite signals can be acquired, in simulation mode.
GPS Off: the receiver is in simulation mode (see above) and cannot be used for actual navigation.
	If no satellite signals are acquired within five minutes, the receiver will prompt the user to re-initialize the receiver.

## Map Page

**Data source**

_**Pointer Feature Information**_
**Name:  Intermittent Str**
**Coordinates:  in UTM**
**Present location to Pointer:**
**	****Bearing - 180******** **
**	****Distance -  0.62 miles**

**Map Page**

**Present location**

**Data fields **

**Pointer – pan with Rocker**

**Scale Bar**

**Notes:**
Set Up the Map Display (cont.)

	Use the rocker key to pan across the map page (becomes a white arrow). When panning over map objects, identifying information is provided, including name and coordinates (in the format chosen in setup). Present location is the black triangle. Receiver can navigate to a remote point selected by the pan arrow. To navigate to a remote point selected by the pan arrow, press NAV button once. Select “Go To Map Point” from the submenu. A straight line will appear on the map from the receiver’s current position to the pan arrow point. The navigate to point will be designated “Map,” as in map point. If the pan point is an identifiable ground feature (such as a road, waypoint, river or named mountain) the navigate to point will assume that feature’s name rather than Map.
	As with any GPS navigation, the receiver can only plot a straight line to the destination point. To discontinue navigation, press NAV button and select “Stop Navigation.”

## Map Page Menu

**Map Page Menu**

**Setup Map**

**Press Menu**

**Notes:**
Set Up Map Display

	Map page can be configured using the map menu Map Setup option.
	Map functions such as data fields can be turned on and off. Different data fields may be selected (up to a maximum of four) for display on the map page. Map detail can be increased or decreased. Map can be manually panned using the rocker key. MapSource data (if loaded in the receiver) can also be configured for display.
	How the map is displayed during navigation can also be configured by the user. There are two options for this: track up and north up. Change map orientation through the Map Setup screen: select the Map tab, then scroll to Orientation and press Enter button. Toggle to select the option you want.
	Play with the various map setup options and sub-menus to see what they do.

**We will set location information before Navigation**

## Goal:  Storage Locations 

**User Waypoint List**

**(Active) Track Log**

**Saved Tracks**

**Notes:**
We are only concerned about these storage locations – there are more.  For example, one of the storage locations we don’t address is on the Main Menu at the bottom.   

Some receivers have only 1 bucket into which all collected data is stored.  This receiver has  separate buckets for collected data – Active Track, Saved Tracks, Points, Routes.  When the Waypoint bucket is full, you cannot store any more Waypoints, even though the Active Track bucket is empty.   We are concerned in this class with Tracks and Points, only.  

## Check Tracks and Points 

**Check Tracks and Points **

**Press Menu**
_**Twice**_

** ****Note:****	**_**File Name**_**	**_**Data Type**_
**	****Tracks****	****Track Points**
**	****Points****	****Waypoints**

**Notes:**
1.  Again, some receivers have only 1 bucket into which all collected data is stored.  This receiver has 3 separate buckets for collected data – Tracks, Points, Routes. (Actually the Tracks bucket is subdivided:  There’s one place for the active track and then there are 10 places for saved tracks.  However, this is probably too much information to share at this time.)   We are concerned in this class with Tracks and Points, only.  

2.  Although there is a file that stores points and a file that stores the tracks, it may be useful for students to know that the track file is made up of just track points or “positions,” it is not a line file like what’s in a GIS.

## Points

**Points**

**Press Menu **_**Twice**_

**Notes:**
We’re going to empty the Points bucket first.  

## Open Points Page

**Press Enter**

## Open User Waypoint List

**Press **

**Maximum Waypoints - 1000 **

**Delete Waypoints**

**Notes:**
Again, we want to delete any waypoints in the User Waypoint List.  The following slides show how.  

From Garmin.com, for the GPSmap76, GPSmap76S:
Changes made from version 2.09 to 3.10:
Increased the active track log to 10,000 points. 
Increased each saved track log to 750 points. 
Increased user waypoints to 1,000 waypoints. 

Manual on Garmin website must be old, it says 500 waypoints.

## Goal:  Track Log Setup 

**Set according to field needs**

**Notes:**
Now we are ready to select how we want to collect data.  

## 		Open Track Page Options

**	****	****Open ****Track Page Options**

**Press Menu**

**Notes:**
Start from the Track Page.  

## 	Open Setup Track Log Menu

**Press Enter**

## 	Open Recording Method Options

**Notes:**
Distance means that a position will be collected after you have traveled the specified distance interval.  Note:  The units for this function are provided in the Setup Menu, Units, Distance and Speed.  The choices are:  Nautical feet, Nautical meters, Statue, Metric.  If you select Statue then the limitation is hundredths of a mile (52.8 feet).  If you select Metric, then limitation is hundredths of a km (10 meters).

Time means that a position will be collected after the specified time interval.  Note:  the minimum is 1 second.  

Auto means that the software will collect according to the frequency selected (Most Often, More Often, Normal, etc.) and with the goal of getting the user back to where the user started.  If the user travels slowly it may collect less frequently than when the user travels at a higher speed.  If the user is making lots of turns, it may collect more frequently.    

## 	Open Setup Track Log Menu

**Press Enter**

## Select Time

**Set according to field needs**

## Consideration:  Duration

**Max:  10,000 track log positions for Active Log**
** ****Approximate collection time:**
**	****1 second Interval Value – 2.75 hours **
**	****2 second Interval Value – 5.5 hours **
**	****5 second Interval Value – 13 hours**

*Suggestion:*
- Helicopter: 1 - 3 second log interval
- Vehicle: 3 - 7 second log interval
- Walking: 5 - 10 second log interval

*Tip: Logging interval may be changed during collection*

**Notes:**
1 second interval:
	 60 points in 1 minute, 10,000/60=166 minutes, /60min/hour=2.75 hours 
2 second interval
	30 points in 1 minute, 10,000/30per=333minutes, /60minperhour=5.5 hours
5 second interval
	20 points in 1 minute, 10,000/12 per minutes, /60 minutes per hour = 13 hours

## Consideration:  Density

**Consideration:  Density**

**599 points**
**1 second interval**

**125 points**
**5 second interval**

**Notes:**
The perimeter of a fire outside of Boise, Idaho, was mapped from a helicopter using a Trimble Geo3.  The collection interval was 1 second.  I used Pathfinder Office software to delete positions so that only every 5th position was saved, thus creating another file with a collection interval of 5 seconds.  On this slide are the maps of the 2 files.  On the following slide are the calculations from Pathfinder Office.
