I didn’t think there was any reason to mansplane the image. Lol. I think I posted an adequate representation of the input and did a good job of describing what I wanted to use OpenCV to find on there. Also who cares if the information was already out there on the internet in some other form? I was asking for pointers using OpenCV to generate it. Isn’t that what this forum is for?
As I mentioned before I don’t need geographical coordinates. I need pixel coordinates off the input image so I can map each airfield to an exact position on the paper when it is printed on based on the image size and DPI settings both of which may change.
Finally some useful information. I will explore the matchTemplate() function. It is unfortunate the person who was assigned to moderate this group attacks newbies to OpenCV this way.
