Combine one to many control networks with common control points.
| Overview | Parameters |
DescriptionThis program will create a control network by combining control points from one or more control networks into single points that satisfy image distance criteria. It employs a more robust/direct technique than cnetmerge. This technique evaluates each control point in all input networks by finding all candidate merger control points who have a measure within IMAGETOL. Then, for each candidate point, the average distance of the measures in the candidate to a measure in the source point is computed. If the average distance to any measure in the source point is less than IMAGETOL, then the candidate point and source point are merged. The candidate control point is disabled so that it will never be considered for another merger and the now augmented control point is added back to the search pool for further merger considerations, which can occur when other common measures are considered. When all control points have been searched and all mergers have taken place, a new single combined control network is created. Note that this application can be ran more than once and directly on the output of any past run (in other words, you need only provide a single network, if desired).

Parameters
|
Input: CNETBASE
Description
The base control network file to which others will be matched.
| Type | filename |
|---|---|
| File Mode | input |
| Internal Default | None |
| Filter | *.net *.cnet *.ctl |
Input: CNETFROM
Description
A control network that will be matched to the base (i.e. master) network.
| Type | filename |
|---|---|
| File Mode | input |
| Internal Default | None |
| Filter | *.net *.cnet *.ctl |
Input: CNETLIST
Description
A list of control network file names that will be matched to the base (i.e. master) network.
| Type | filename |
|---|---|
| File Mode | input |
| Internal Default | None |
| Filter | *.lis *.txt |
Output: ONET
Description
The output Control Network, which is the combined result of the input networks.
| Type | filename |
|---|---|
| File Mode | output |
| Internal Default | None |
| Filter | *.net *.cnet *.ctl |
Output: TOSN
Description
Provided with a filename in this option, all the cube serial numbers that are contained in the network are written to this file as soon as it is determined in the processing.
| Type | filename |
|---|---|
| File Mode | output |
| Internal Default | None |
| Filter | *.lis |
Output: NETWORKID
Description
The NetworkId keyword for the newly merged ControlNet will be set to this given value. The Networkid is a single word identifier or name assigned to a Control Network.
| Type | string |
|---|---|
| Internal Default | None |
Output: DESCRIPTION
Description
The Description keyword for the newly merged ControlNet will be set to this given value. This should be a brief description of the purpose of the merged control network.
| Type | string |
|---|---|
| Internal Default | None |
Parameters: IMAGETOL
Description
The acceptable distance, in pixels, for merging points.
| Type | double |
|---|---|
| Default | 1.0 |
Parameters: KDNODES
Description
Number of leaves in the kd-tree structure.
| Type | integer |
|---|---|
| Default | 10 |
Parameters: SETAPRIORIBEST
Description
When TRUE, all points apriori latitude/longitude surface point is updated to use the best one available. This is often the resulting coordinate after jigsaw has adjusted the surface point.
| Type | boolean |
|---|---|
| Default | false |
Parameters: CLEANNET
Description
When true, all invalid or ignored control points and measures are removed from the output control network as one of the main objectives of this application is to remove redundancies and mimimize the size of networks. However, for evaluation purposes, you can set this to false, which will preserve all control points.
When specifying the minimum number of measures/control point using the MINMEASURES parameter, any control point that does not meet this criteria will also be removed from the netwrk when CLEANNET=true, otherwise these points will be set to ignored.
| Type | boolean |
|---|---|
| Default | true |
Parameters: CLEANMEASURES
Description
When true, all invalid or ignored control points and measures are removed from the output control network as one of the main objectives of this application is to remove redundancies and mimimize the size of networks. However, for evaluation purposes, you can set this to false, which will preserve all control points.
When specifying the minimum number of measures/control point using the MINMEASURES parameter, any control point that does not meet this criteria will also be removed from the netwrk when CLEANNET=true, otherwise these points will be set to ignored.
| Type | boolean |
|---|---|
| Default | true |
Parameters: MINMEASURES
Description
This allows users to disable points that have less than MINMEASURES control measures/control point. For example, if you want to flag all points as ignored with 2 measures or less, set MINMEASURES=3. Points that don't meet this critieria are set to ignore and are subject to the CLEANNET action requested by the user (i.e., all ignored points are removed from the network if CLEANNET=true).
