Historical repeated photographs. Method of ground-based photo-monitoring

In the Themes / Historical photos of information system Neogeograph you can see the photographs of streets and buildings of Yekaterinburg city, which were taken at different times, with the same points of shooting with similar parameters of the external orientation of the cameras.

Thus obtained photos allows a researcher to perform qualitative and quantitative analysis of changes in the environment. Method of photographing with the same points of photography of natural or anthropogenic landscape elements with subsequent comparative analysis of received images has the the name: the method ground-based photographic monitoring. 

It was first designed by Professor S. Finsterwalder for landscape photographs at the end of the XIX century. Since 1888, he photographed and put on a map glacial changes in the Eastern Alps (Hall, 2001).

Despite the fact that the method was designed over a hundred years ago, wide popularity it has received relatively recently. This is due to the development of information technology, related both to the development digital photographic equipment, which is accessible to a wide range specialists in various disciplines as well as software development, providing good opportunities for image processing and analysis, data storage and multi-user access to the results of the analysis.

In the Urals, a method of ground-based photo-monitoring actively used in research of climate driven spatio-temporal dynamics of alpine vegetation on the mountains in the Polar, Northern and Southern Urals (Shiyatov et al, 2005; Kapralov et al, 2006; Shiyatov et al, 2007; Fomin et al, 2007; Fomin, 2009).

The images in section Themes / Historical photos of information system of neogeograph.com allow you to visually assess how different urban environment of Yekaterinburg in the last 100 years.
