<div dir="ltr">Hi Richard,<div><br></div><div>The Historic England aerial photography team have been working on a similar sort of project which they recently released (see <a href="https://historicengland.org.uk/whats-new/news/new-virtual-aerial-map-allows-everyone-to-explore-englands-archaeology-from-the-air/">https://historicengland.org.uk/whats-new/news/new-virtual-aerial-map-allows-everyone-to-explore-englands-archaeology-from-the-air/</a>). Perhaps they might be able to provide some advice on how they did it?

<p>Hi Richard:<span style="font-size:12pt"><u></u><u></u></span></p>
<p>You would require a couple of things:<u></u><u></u></p>
<p>1) Camera interior orientation which would include the lens calibration<u></u><u></u></p>
<p>2) exterior orientation which would include precise coordinate at time of exposure as well as the pitch, roll and yaw of the camera.<u></u><u></u></p>
<p>3) the offsets from the camera film or sensor center to the center of the aircraft gps antenna.<u></u><u></u></p>
<p>4) an accurate DEM or your target area<u></u><u></u></p>
<p>If you have the above data, you can autoreference your images.<u></u><u></u></p>
<p>If the images have a high endlap and sidelap, you could use commercial software such as Pix4D or Global Mapper to orthorectify the images based on structure from motion. Check into drone orthorectification software.<u></u><u></u></p>
