This document explains the use of geoDataClient in connection with TruFlite for Windows.

- geoDataClient...a gazetteer application for Windows. Enter coordinates or a U.S. address and the
                  matching data are downloaded from USGS and U.S. Bureau of the Census servers.
- TruFlite........TruFlite for Windows, 3D terrain visualization program.

Start geoDataClient

In the address field, enter (without quotes): "100 Eugene Ave, Mt. Shasta, CA"
Request the coordinates for that address: Pushbutton "Geocode..."
Make sure that output is produced (in the log box in the center of the dialog) reading:
"quad: -122.807675, -121.807675, 41.808410, 40.808410"
Request the data files for those coordinates: Pushbutton "Proceed..."
The download may take a couple of minutes. Watch the various steps and make
sure the output ends with this statement: "Download successfully finished."

Four files were created (with NNNNNNNN being an arbitrary 8 digit number):
NNNNNNNN_el.tga
NNNNNNNN_tx_c.tga
NNNNNNNN_1.trf
NNNNNNNN_2.trf

Close the program: Pushbutton "Close"

Start TruFlite, open one of the *.trf files, say NNNNNNNN_1.trf
(with NNNNNNNN being an arbitrary 8 digit number).

Select "Calculate/Final..." or simply press Ctrl+F.

A series of 100 output files is created: "NNNNNNNN_output_1_nnnn.tga",
where nnnn is a four digit serial number of the still image.

To limit the number of images rendered to one, in the "Frame Number"
groupbox, replace "To: 99" by "To: 0" and then press Ctrl+F again.

To zoom in, double the focal lengths of the "First Frame" and the
"Last Frame" (1200 -> 2400) and then press Ctrl+F again.

To turn the camera horizontally, change the "Heading" value.
To pitch (nod) the camera, change the "Pitch" value and then press
Ctrl+F again.

To flatten the terrain, reduce the "Elev. z scale" value and then press
Ctrl+F again.
