FSXA Adding a Satellite Image to ADE

With typical aerial images I can usually get within 20 feet or so, which should be plenty close even for someone that is familiar with the airport. As for runway information, AirNav has the exact lat and lon values for each end of the current runways. Then you use an aerial image to determine how much shorter the runways were back then vs current day.

An aerial image of KBHM from 1970 is here:

https://www.historicaerials.com/viewer#

Type in kbhm in the search box in the upper left of the map.
Click on Aerials at the upper left
Choose the year you are interested in.
Also check out the Topos button, there are often other years available there (but the accuracy of such topos vary widely).
Click the Measure button, click on Create a New Measurement
Click on the map, a dot will appear with the lat and long in the measure box.
Click on the map again, a measurement will appear for the distance between the two dots.
Click on Cancel to create a new measurement, or click the Measure button to close the box.

I take screen shots from this page (zoomed in enough to give me reasonable detail) and paste them together in my paint program, creating a background image of the full airport. Don't change the zoom value once you start taking screen shots. I then add this to ADE. I correct any perspective errors based on the runways.

And no, these values will not be exact to the foot. But between the accurate modern runways and the aerial image, you can get very close.

Hope this helps,

Hi Ken:

USGS has (2) B+W aerial photos of KBHM from 1970 apparently identical to images used on the site Tom linked above. :scratchch

These have USGS watermarks that are outside the area of interest within the overall extent of coverage of those images.

NOTE: These must be rotated 180 Degrees Counter-Clockwise before used for background images without re-projection.

However, they will first require Geo-rectification to their real world positions, so that the 'virtual-display-only' relative coordinates used by Global Mapper can then be corrected.

I shall take a look at updating and posting the Metadata for these 1970 photos of KBHM initially, rather than the color IR imagery you originally cited above. ;)

Thanks Guys,

I can use these images. The B&W image from 1970 really has a better quality than the 1981 image I found. I wish the 1981 image I found had as good a quality.

Yes, I had to rotate that 1981 image before I could add it to ADE. Oh, so you're saying that the 1981 image is infrared? No wonder the colors don't look right. I'll be looking out for the Metadata. By the way, what is Metadata?

Ken.
