Sounds like a case forOpenAerialMap, which after a hiatus, looks like it might get a reboot. Wish I could think of something that was active. They already have a functional beta: OpenAerialMap The OSM wiki also has some notes on aerial imagery.

USGS EarthExplorer is often a fantastic resource for this. Check out, in particular, these datasets: Aerial Photo Single Frames (usually pre-1980) DOQ (1990s) NAPP (1980s-1990s) NHAP (1970s-1980s)

earth explorer via usgs has a slew of satellite datasets, although i'm not sure if they meet your requirements 100%. Aerial Imagery/Aerial Photo Mosaics on Earth Explorer: Aerial Photo Single Frames Aircraft Scanners Antarctic Flight Line Maps Antarctic Single Frames ASAS DOQ High Resolution Orthoimagery NAIP ...

Not free, but UNM has an archive here: https://edac.unm.edu/image-archive/

WMO OSCAR has a (complete?¹) list of current space-borne high resolution optical imagers, defined as instruments with a "spatial resolution in the range of less than 1 m to a few 10 m.". Scroll down to "Current instruments". I'm not an expert in high-resolution optical imagers, but I suspect the problems are as follows: The higher the resolution, the ...

USGS' Earth Explorer is an excellent resource for this type of imagery (unless the US Govt is on shutdown). In this case I would look for NAIP imagery in your area of interest.

A major source for openly available Satellite Imagery is the USGS EarthExplorer Platform. This contains a huge swath of remotely-sensed data at the global scale going back to the 1980s and is updated in near-real-time. An API for this available but it seems the URL to it is broken/forbidden. Here is link to a GitHub project (yannforget/satxplore) created to ...

In June 2013, the City of Calgary, Alberta experienced severe flooding. The City has made very high resolution orthophoto mosaics available at no cost on their website. The licences specifies non-commercial use - see the links below for the specifics. One was captured during the flood (not necessarily at the peak) and another was captured a few months ...

Halfway they state: Furthermore, we introduce a novel large-scale and well annotated dataset for quantitative vehicle detection evaluation - ITCVD. Towards this goal, we collected 173 images with 29088 vehicles, where each vehicle in the ITCVD dataset is manually annotated using a bounding box. I think they used this one as the source: The last-but-...

Depending on the resolution that you require, you could try looking through the available European Space Agency satellite data https://earth.esa.int/web/guest/home

There's various Earth imagery programs, Landsat is one of them. Some of these programs can be found here: http://earthexplorer.usgs.gov/ Select under 'data sets' either the aerial imagery or landsat, then you can select the area and download the images. Due to the fact that a given satellite has limited resolution and takes only so many pictures per minute,...

It sounds like you aren't just looking for satellite imagery but also feature data sets. Satellite imagery is really great for determining variables based on rad bands but getting down to the level of detail required for building footprints is beyond the scope of most (openly accessible) radar systems. I'll point here to a few major resources for geospatial ...

yeah those images are available you can contact me if you are in RWANDA +250 782368287

I have a few set of aerial images taken by an X8+ Drone with a redEdge camera, maybe they will help you. Contact me.
