History
Description
This program creates a latitude/longitude geometric polygon that determines the footprint of the image.
This footprint is used in other programs such as autoseed.

Options:
SINC
Description
This is approximately how many samples in the input image
to skip for every point stored in the footprint.
|
Type
| integer |
|
Default
| 100 |
|
Minimum
| 1
(inclusive)
|
Options:
LINC
Description
This is approximately how many lines in the input image
to skip for every point stored in the footprint.

| 100 |

| 1
(inclusive)

Options:
MAXEMISSION
Description
When this value is provided, footprintinit will only consider points
with an emission angle less than or equal to the provided value.
There should never be an emission angle above 90. However,
planet features can cause abnormalities.

Type
| double |

| Ignore Emission |

MAXINCIDENCE

When this value is provided, footprintinit will only consider points
with an incidence angle less than or equal to the provided value.
There should never be an incidence angle above 90. However,

Limb Test:
LIMBTEST
Description
This parameter is used to specify how limb images are to be handled.
|
Type
| string |
|
Default
| ELLIPSOID |

Option List:
|
|
Option |
Brief |
Description |
| ELLIPSOID | Use an Ellipsoid Shape Model |
If a limb image is detected, an ellipsoid shape model will be
used reguardless of the shape model defined by spiceinit.
|
| SPICEINIT | Use Spiceinit Shape Model |
If a limb image is detected then use the shape model defined
by spiceinit. This is

XY Test:
TESTXY
Description
Tests the ability to project the footprint from lat/lon to x/y
coordinates. If the test fails, an error will be thrown, and the
lat/lon footprint will not be written to the input cube.

Type
| boolean |
|
Default
| FALSE |

XY Test:
MAP
Description
A file containing the desired XY mapping parameters. This
file can be a simple label file, hand produced or created via
the "maptemplate" program. It can also be an existing cube label
which contains a Mapping group. In the later case the input cube
will be transformed into the same map projection, resolution, etc.

History
| Tracie Sucharski | 2005-07-19 |
Original version
|
| Jacob Danton | 2006-02-10 |
Changed input from a list of cube files to a single cube and added appTest.
|
| Brendan George | 2006-06-30 |
Fixed application test
|
| Brendan George | 2006-09-19 |
Added call to propagate and modify the history blob
|
| Tracie Sucharski | 2007-05-09 |
Added error check to insure spiceinit has been run.
|
| Brendan George | 2007-05-21 |
Moved from Geometry category to Control Network category
|
| Steven Lambright | 2007-07-26 |
Moved Control Network category to Control Networks Category (Control Network category is invalid) and updated program description.
|
| Steven Koechle | 2007-10-19 |
Changed name from polyinit to footprint init
|
| Steven Koechle | 2008-08-19 |
Updated to work with Geos3.0.0
|
| Steven Koechle | 2008-12-15 |
Deletes old footprint (generated off cubes serial number) if its found.
New name for blob is just Footprint.
|
| Steven Koechle | 2009-04-17 |
PIXINC parameter was removed, ImagePolygon now uses a new method of
finding footprints
|
| Steven Lambright | 2009-05-29 |
PIXINC re-implemented. This functionality is crucial. Existing polygons will no
longer be deleted if this program fails.
|
| Christopher Austin | 2009-06-16 |
Changed default PIXINC to 100, added test cases.
|
| Christopher Austin | 2009-06-18 |
Added the cross test.
|
| Christopher Austin | 2009-07-01 |
Added EMISSION and INCIDENCE
|
| Christopher Austin | 2009-07-09 |
Changed param EMISSION to MAXEMISSION, and INCIDENCE to MAXINCIDENCE.
|
| Christopher Austin | 2009-07-21 |
Added LIMBTEST parameter, and fixed multiple tests, including multiple
PIXINC coverage.
|
| Christopher Austin | 2009-07-28 |
Replaced PIXINC with SAMPINC and LINEINC.
|
| Christopher Austin | 2009-08-05 |
Changed the maximum value of MAXEMISSION and MAXINCIDENCE to 180.
Added TESTXY and an app test for it.
|
| Christopher Austin | 2009-08-20 |
Changed SAMPINC and LINEINC to SINC and LINC for consistancy with
camstats.
