Several grid flights (at different heights) OR oblique imagery with sufficient overlap.ġ.

Non planar scene (not all objects having the same height).

If you have other concerns, please share them here (or DM) to discuss.To get the internal camera parameters for a perspective camera that does not exist in Pix4Dmapper's database:Ī good dataset with the following properties is required: If you are just looking to make sure that your habits arent splattered across the web when you share a selfie, stripping the elif and resaving with compression should meet your needs. Like all things, depends on the threat vectors and the adversaries. Then you have security cameras all over, that could be used to tie you to looking though a view finder. There is the potential for data leakage from the camera if it is a phone, say an iphone recording that it took a picture at zxy location, outside of the image metadata. There are also plenty of other correlation techniques to tie a photo to a person.

Potentially there could still be other analysis, but unless you are trying to mask your identity when taking pictures of potential terror attack sites, the image likely isnt going to be analyzed by those with the power to get past the tips mentioned. You can also do this in something as simple as paint or gimp or a another portable app (and there are plenty of portable command line, batch edit tools to resave files in another format with whatever settings you want.) If you are looking for a platform independent option, there are sites like, where you can upload your image, and then save it as another format, say jpeg, and adjust the compression / quality, which is going to render most additional analysis moot.

Stripping the exif data as mentioned + some sort of resave of the image is going to suit 99% of needs.
