HEIGHT Element

Overview

HEIGHT
Used to specify height settings for the GPS in ArcPadPrefs.apx.
antennaheight optional xs:double
The antenna height specified in the GPS Height page of the GPS Preferences dialog in ArcPad, in meters. This value is subtracted from the height reported by the GPS receiver.
geiodseparation optional xs:double
The geoid separation specified in the GPS Height page of the GPS Preferences dialog in ArcPad, in meters. This value is subtracted from the height reported by the GPS receiver.
units optional xs:string
The units code that specifies height units for the geoid separation and antenna height in the GPS Height page of the GPS Preferences dialog in ArcPad.
usemapunits optional Restriction of xs:string
Specifies whether to use the units of the map's coordinate system when storing GPS elevation. If the coordinate system's units are degrees, the height units are meters.

Remarks

The units, geoidseparation, and antennaheight attributes are used to calculate the reported GPS height.
The reported GPS height is calculated as FEATUREHEIGHT = GPSHEIGHT - GEOIDSEPARATION - ANTENNAHEIGHT, where:
FEATUREHEIGHT = reported/stored GPS elevation (Z-value in ShapeZ files)
GPSHEIGHT = height reported by the GPS receiver (HAE, where available)
GEOIDSEPARATION = value specified in geoidseparation attribute
ANTENNAHEIGHT = value specified in antennaheight attribute
