You can export survey results to a popular
geographical information program,
Google Earth™. This functionality is intended for large
outdoor GPS-assisted surveys that you conduct using TamoGraph. By
exporting data to Google Earth, you get an additional analysis
option that integrates TamoGraph visualizations with rich
geographical data provided by Google Earth. Data is exported in to
a single Google Earth file (KMZ format) and can be viewed on any
computer where Google Earth is installed.
To be able to export data to
Google Earth, your survey project must be GPS-calibrated; see
the GPS Calibration
chapter for more details. When
you open the KMZ file in Google Earth, your visualizations are
overlaid on top of the satellite images or street maps. You can
control which layers/visualizations are shown using the
Places
interface element in Google
Earth. You can also rearrange the report according to your
requirements by dragging the tree nodes in the Places
interface element; such
rearranged reports can be saved into a new file. You can learn more
about working with Google Earth by visiting http://earth.google.com/support/.
There are two methods of data export from
TamoGraph to Google Earth.
Current Visualization Export
This is the simplest method that lets you
export a single visualization that is currently selected.
Select a visualization on the toolbar, use the
Project
=> Save current
visualization menu
command, select Google Earth
(*.kmz) as the file
output format, enter a file name, and then click
Save
to save the visualization. The
resulting KMZ file can then be opened in Google Earth by
double-clicking on it.
Export from the Report Dialog
For more advanced options you can use
the Project
=> Generate Report
menu command. In the report configuration dialog, check
the visualization(s) and survey(s) you would like to export and
then select KMZ (Google
Earth) from the
Format
drop-down list. Note that not
all the surveys can be exported to Google Earth; only those surveys
that were GPS-calibrated can be exported because the application
must know the exact coordinates of your map to be able to export
data ; see the GPS Calibration
chapter for more details.
Click Save to generate a KMZ file. Unlike the first
method that includes a single visualization, this method allows
TamoGraph to generate a complex report file that contains a
tree-like structure of layers that can be navigated and displayed
in Google Earth. Visualizations and auxiliary elements can be
accessed in the Places
interface element in Google
Earth. You will be able to select layers, view locations of APs,
turn on and off visualizations, and further customize the
view.
