an.agsetup, or.agdata file, this will be the survey that is exported. Non-active surveys will stay in the
display. At any time you can remove an elevation survey, and collect a new one.
This topography layer can be turned on/off as a
reference layer during any operation using Enable
checkbox on Topography screen (shown above) or
using the Topography checkbox on the Map Options
screen (see
“Map Legend tab” on page 40).
This can provide you with valuable information in
regards to the highs and lows of a field when you
may not be able to visually tell with the naked eye.
Surveying and Tiling operations will probably benefit
the most with respect of where to place the mains
and laterals in a field.
If you have RTK GPS reception, you are allowed to
collect an elevation survey. This will allow you to
collect the Lat/Long and elevation values as you
traverse the field. A point will be dropped every 3
meters as you drive regardless of speed, or direction. If
you are collecting during operations like planting or
application using autoswath, it will also log points
outside the boundary of the field (i.e. through a
grassed waterway) to get the most information
throughout the field.
It is critical that the GPS Antenna to ground measurement is correct in your configuration, any error in
this measurement, will add to the error in the data logged.
The following are suggestions to get the best possible elevation survey for a given field. Following
these recommendations will provide the best results for your field.
• Keep swaths in the field to 60ft (19 M) or less, the closer the better
• Driving a dedicated route at the lowest or highest points in a field (i.e. lengthwise of a grassed waterway,
or at the top of a ridge) then traversing the field in regular swaths will provide the best detail of the field
• If surveying with the tile plow antenna, ensure that the plow is in the fully raised position
• Driving too fast with mounted plows, can cause bouncing and affect quality
• Surveying with harvesting equipment can provide streaked maps as the hopper filling and unloading can
affect the height of the vehicle, and therefore antenna
