PDT for Imagery Intelligence

New visualization technologies are driving changes in the way both Image and Geospatial Analysts interact with their data. Pliable Display Technology is one such emerging technology that has recently caught the attention of the National Geospatial-Intelligence Agency (NGA). PDT can result in significant efficiency and accuracy gains when integrated within an Electronic Light Table (ELT) environment. There are a number of imagery-based intelligence activities where PDT is directly applicable:

PDT and Change Detection Change Detection
Chain multiple PDT lenses together to track changes over time, while still maintaining complete situational awareness. The PDT lens has its own unique in-place user interface that makes it precisely controllable by the analyst. PDT's unique folding capabilities bring localized regions of interest being compared over multiple image sets next to each other for side-by-side comparison.

PDT and image enhancement Auto Dynamic Range Adjustment Optimize image processing with PDT, by selectively adjusting image properties within a localized region.
PDT and vector collection Ground Control Point Inspection
Line up imagery with known reference points using PDT to quickly locate Ground Control Points.
PDT and mosaic images Mosaicking
PDT is an ideal tool to check for errors in registration or scaling in mosaicking. Move a PDT lens along the seams of a mosaic to inspect for flaws and misalignments and perform corrections without losing awareness of location. In the screenshot at left, the arrows indicate a misaligned mosaic tile visible in the PDT lens.
PDT and recorded lens trails Snail Trails
Use the real-time PDT lens to perform image exploitation across a large image. Turn on the snail trail option to leave a lens trail as well as save and replay searched ones. In the screenshot at left, the PDT lens has followed a snail trail over multiple ground control points.

PDT and mensuration

Precision Chipping, Annotation, and Mensuration
PDT's Undisplace functionality increases the efficiency and accuracy of tasks such as measurement and annotation. Measurements spanning a large extent of the visible exploitation area can be performed at high precision, without zoom and pan steps.

PDT and image filtering Filtering
The PDT lens is an excellent metaphor for visualizing multi-layer information from a multitude of data sources. For example, filter multi-spectral data that incorporates an infrared layer, and check for suspicious hot areas in the mountains. The PDT lens provides visualization of the processed detail in the local region of interest, while also displaying the situational context.

In the screenshot at left, active filtering in a PDT lens shows suspicious "hot spots" in a mountainous region.

Once integrated into your ELT environment, PDT's unique user interface and detail-in-context functionality will enhance and extend the existing set of tools used for precise inspection and adjustment. In one NGA Imagery Analyst's words, "PDT would enable me to perform data collection, data extraction, and editing more efficiently."
