Add Method 2--Enter Latitude/Longitude:
This allows you to hand-enter known geodetic coordinates for
the local position. The elevation should be the ellipsoid elevation in the current job units if a geoid model is
not applied. If a geoid model is applied, then the elevation should be the orthometric elevation in the current
job units. This method allows manual entry of a localization file without occupying points in the field. Note
that you do not enter the decimal point for decimal seconds.
If you use manual entry of a localization data set, it is important that you either utilize an existing base GPS
receiver with the fixed antenna location that was used to survey the original geodetic positions, or that you set
up your base on a known GPS position measured previously using that localization data set. Good survey
practice would include checking into known positions to verify the quality of your hand-entered GPS
localization and verifying low residuals in the Localization screen. With all data pairs used for both horizontal
and vertical control (none turned off), the resolutions for this data set will appear.
Add Method 3--From Raw File:
This allows you to use a point from the raw data file that has been
previously collected via GPS. This is just like Read from GPS except you are recalling a point previously
measured and stored in the raw file. For this to work, you must have the base antenna in the same position as
when the original raw file was collected, or you need to set your base antenna over a known coordinate from
the original survey, and enter those original coordinates and the new base antenna height within the command
Configure Base.
 Delete
: Allows you to delete the selected item from the list. Note that it is not necessary to delete a localization
point if you simply want to avoid using it. You can disable both the horizontal and vertical component of the point,
but keep it available for use later.
 Edit
: Allows you to edit the selected item in the list. It will display the northing, easting and elevation of the
localization point, which can be changed.
 On/Off
: Allows you to remove the horizontal or vertical components of your localization points. This is a
frequently used feature that enables the use of one point for vertical control only (turn off its horizontal component)
and other points for horizontal control (turn off their vertical, if appropriate). Points with no known elevation (0 for
example), would obviously be used only for horizontal control, as shown in this example.
