Resolution of phantom 3 at 300' AGL?

AFAIK:

Camera sensor Sony EXMOR 1/2.3” (diagonal 7.81mm, 6.16 x 4.62mm)
Effective pixels: 4072 × 3046 = 12.40 M (total pixels: 4168 × 3062 = 12.76 M, active pixels: 4024 × 3036 = 12.22 M)
Lens FOV 94°, focal length 3.61mm (or 20mm @ 35mm format equivalent) f/2.8
ISO Range 100-3200 (video) 100-1600 (photo)
Electronic Shutter Speed 8s - 1/8000s
Image Max. Size 4000 × 3000
Video Recording Modes:
UHD: 4096 × 2160p 24/25, 3840 × 2160p24/25/30
FHD: 1920 × 1080p 24/25/30/48/50/60
HD: 1280 × 720p 24/25/30/48/50/60
Max. Bitrate Of Video Storage 60 Mbps

...so the image sensor resolution is somewhat vague. The OP wasn't quite clear if s/he was doing images or video and in which settings ... OP wanted 15 mph which is about 50% of P3P max speed but didn't mention lighting, ISO, shutter speed which contribute to image blur...

This is for mapping application in which the images collected will be used by post processing software like Pix4d or maps made easy to produce highest possible quality maps.
 
I see some using 4K figures. This isn't possible if shooting video w the advanced. Just thought the OP should know it would be different if using video between the 2 versions. Probably stating the obvious but didn't see it mentioned. Unless my
Old eyes missed it.
