Store Points is the principle data collection routine for GPS equipment.  Store Points interacts with numerous settings, including the feature codes, and will draw line work.  The Store Points screen in GPS shows the cursor moving on the screen in real-time.  Shots can be taken anytime by pressing Enter.  The screen will pan automatically, so you are always in view as you move.  Points will plot on the screen as shots are taken.


In GPS mode, Enter has only one function:  Read & Store.  The after-shot antenna height and description prompt can be enabled in Configure (C or ALT-C from the Store Pints screen.). If you dont have the height and description prompt turned on, then each shot is a single press of Enter, and you must enter antenna height, description, or point ID changes prior to pressing Enter and taking the shot. 



For GPS, coordinates, status (Fixed, Float, Autonomous) and HRMS and VRMS accuracy estimates are displayed at all times. The icons at the left are for zooming and panning.  From top to bottom, they are:  zoom extents, zoom in, zoom out, zoom window, zoom previous and point display control.  If you prefer to work in a pure text screen, without graphics, you can tap the helmet icon and select TEXT. The following dialog will appear.



The Text screen uses a large character size for easy viewing, and limits options to Monitor/Skyplot, Offset and Store.  You can return to the graph view by tapping the GRAPH button.  You can also temporarily view your points on the screen by tapping Map, then tap Back to return to the text-based data collection screen.  Note that the program will remember which screen you were in last (Graph or Text) and return to that mode of data collection automatically.


In addition to pressing Enter, Points can be Stored by selecting this icon (ALT-S).


Average


With GPS, since shots tend to cluster around the true point location, it may add to accuracy to Average 10 or more GPS readings when taking measurements.   You will be prompted for how many readings to take (up to 999).  Taking 100 readings is also a way to gauge how fast your GPS equipment takes measurements.  If 100 readings are taken in 10 seconds, you are reading at 10 per second, or 10 hertz (hz).  After the readings are taken, a display appears showing the range and standard deviation of the readings.



Offsets

This icon leads to Offset reading screens with options for keyed-in offsets as well as offsets taken by laser devices.  These devices can measure distance only or distance and azimuth (ALT-O). See Store Points (GPS Offsets) for more details.

Configure

This icon will take you to the Configure dialog, also found on the EQUIP tab. From this dialog you can set the number of readings to average, specify to only store fixed readings, and turn on or off the Hgt/Desc prompt on Save (ALT-C).


Monitor/SkyPlot

This icon will take you to the Monitor/SkyPlot screen for GPS status, coordinates and Lat/Long display (ALT-D).
