With the photo comparison tool you can view two aerial images of the same specific geographic area at the same time. Flights are performed without a chronological or spatial order, so you can find places where there is no photographines in a particular year. WMS services offered by various state and regional institutions have been used to achieve the interactive map. Here are some examples where you can observe changes in localized spaces over time.

As reported by IGN, the minutes are raster files corresponding to the digitization of the handwritten paper maps preserved in the IGN Technical Archive. This is the work leading up to the completion of the National Topographic Map, in some cases several decades apart from the publication of the first edition of the MTN of the area. This type of documents were mainly made between 1870 and 1950 and are classified into planimetric minutes, altimeymetric minutes and joint minutes of altimetry and planimetry.
