Commercial Aerial Thermal Mapping
The amount of commercially useful information available through thermal imaging simply defies description. Various posts on this site deal with only a very small fraction of the types of valuable information thermography provides.
One of the more promising applications of aerial thermography is speculative thermographic mapping. RedLens has developed mass aerial collection techniques that allow the collection of thermographic mapping data sets and the automated processing of those data sets. Automated collection and processing decimates production costs and time, opening the door to speculative collection and marketing at very low price points.
The following example is of a structure (hotel) somewhere on earth-I've deliberately adulterated the latitude and longitude readout. This image is actually a portion of an aerial mapping mosaic shot during process development and serves as not only an excellent example of an automated deliverable but of a roof apparently in need of repair. This sort of prospecting can obviously be of great interest to a roofing company but the products are by no means limited to that sector. The same type of deliverable can be provided for an area of 20 miles by 20 miles, with a "zooming" feature to view the images at maximum enlargement.
The metrics (area of the roof section and area of the affected area) were all derived from resources other than the imagery or any proprietary data. Adobe's Photoshop Extended CS5 was used to quantify areas (it has a robust measurement functionality), and Flash CS5 Pro was used to prepare the presentation using modular code snippets so that the same presentation shell can easily be repurposed with a different subject.

I am not seeing the thermal image, but I am using a similar approach for perparing accident scene layouts for preparation of event simulation. This provides real time evaluation on the actual streetscape(time limited.) We verify the scale for dimensioning with physical confirmation of 3 points when needed.
Aerial thermography for roofs is a well accepted qualitative evaluation from which you can focus your inspection on specific areas of concern. The quantitative and physical evaluation will help you determine what measures are needed to remedy the defects.

To view the thermal overlays select either “Show Color Thermal Overlay” or “Show Monochrome Thermal Overlay” at the bottom of the column of check boxes-apologies for having it positioned so poorly.
