Photo interpretation - presence or absence of roads, paths

Photo interpretation - presence or absence of roads, paths

One of the few ways that the presence or absence of roads can be substantiated is the photo-interpretation.
So we can identify and characterize:
roads or
paths of various categories
trails
rural roads
street under construction
abandoned roads
vehicular streets, asphalt or cement roads
bridges and junctions
railway line single or double.

It is also possible characteristic figures to be measured.

The presence of road in old aerial photos of 1960 or 1945 documents the public character of the street that is particularly beneficial to the soundness and the access of a plot.
The existence of such pathways enables potential splitting of large properties into smaller according to the applicable limits of partition.
For example, in areas outside the city plan where the partition boundary is four (4) acres, the existence of a public road, which the initial property has facade on it, is a necessary condition for the partition. Thus, the new land parcels are required to have façade on the public highway of length twenty (25) meters.

The research of photo interpretation combined with map data, drawings, photographs and other formal documents, contracts etc.
