Using PAI data (Positional-Accuracy Improvement).
Adjust is a full feature, AutoCAD based rubbersheeting processor that can be used in PAI applications. The PAI Link files can be directly read into Adjust, displayed, edited and used for rubbersheeting. The following example shows the features and benefits of Adjust as applied to a PAI project.
The first step is to read in the Link file(s). Any number of files can be read using Adjust’s “Freeform Format” option. Once the links have been read in, they can be graphically displayed (in any color you choose). Here we see the Example drawing with both PrePAI (Magenta) and PostPAI (Blue) data. The links are shown in Green.
A special Octagon Shaped Symbol is used to display very short or Zero Length Links. Adjust display the links in Graphical form only – OR you can use the Hard Calibration Option to draw the links as Polylines. This allow the direct editing of the links.
In cases where obvious Link Errors are present, Adjust allows you to review and delete them. Here we see two links that are probably Bad (moved and shown in Red for clarity). This obvious conflict should be corrected before rubbersheeting.
Once the Calibration Set is refined, we can proceed to rubbersheeting. Here we see the Project Linework (in Red) displayed with the Post PAI data. This slide shows the Project Linework along with the Final Calibration Set.
Adjust then processes the linework, honoring every link to produce a Finished Project, shown in relation to the Post PAI data.
