Historical mapping, minutes and first edition of IGN topographic map
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.
