Description
This application is for camera development and is not supported for general public use.
This program will do basic tests for new camera models. There are calls
to SetImage(sample, line) and SetUniversalGround(lat, lon) that are used
to test translations from image coordinates to geometric coordinates and
back. Either one of these calls can fail and are indicated by unique
special pixel values. If a call to SetImage(sample, line) fails, the
output image is set to the Low Representation Saturation (Lrs) special
value. Failures in calls to SetUniversalGround(lat, lon) are set to High
Representation Saturation (Hrs) value. The number of pixels for which
SetImage(sample, line) fails is output as FailedConversionsToLatLong.
The number of pixels for which SetImage(sample, line) succeeded but then
SetUniversalGround(lat, lon) failed is output as
FailedConversionsToSampleLine. If ERROR is chosen for FORMAT, then
statistics on the error will also be output.

| LAT | Output latitudes | Output is latitudes; NULL if SetImage(samp,line) failed |
| LON | Output universal longitudes | Output is universal longitudes; NULL if SetImage(samp,line) failed |
| ERR | Output sample/line errors |
SetImage(s,l) will return a (lat,lon). This (lat,lon) will be passed into SetUniversalGround(lat,lon).
The output is the distance from the input (sample,line) and the resulting (sample,line) after the
SetUniversalGround(lat,lon) call. This tests how accurate the camera model converts l,s->lat,lon->l,s
|
| SAMP | Output sample |
SetImage(s,l) will return a (lat,lon). This (lat,lon) will be passed into SetUniversalGround(lat,lon).
The output is the resulting sample after the
SetUniversalGround(lat,lon) call.
|
| LINE | Output sample |
SetImage(s,l) will return a (lat,lon). This (lat,lon) will be passed into SetUniversalGround(lat,lon).
The output is the resulting line after the
SetUniversalGround(lat,lon) call.

Now tests the center of each pixel instead
of edges - this upset pushframe tests a lot and
produced inaccurate results.

Corrected a bug where the sample was off by one (used as a 0-based
index instead of 1-based); Set failures in calls to SetImage (Lrs)
and SetUniversalGround (Hrs) to special pixel values so they are
distinguishable. Documented this behaviour.

Now outputs statistics on the number of failed calls to SetImage and
SetUniversalGround. For FROMAT=ERROR, statistics on the
error are also output.
