In the time before the geoglyphs? popularization by the German scientist Dr. Maria Reiche, geoglyphs were subject to considerable destruction by humans, trough geoglyphs and lines led by local roads, areas served for military exercises, etc. This problem was solved by the inclusion of the area into the UNESCO World Site in 1994. The greatest contribution to the protection of geoglyphs and lines was by Dr. Maria Reiche, who died in Peru in 1998. After 24 years of protecting the famous Nasca?s geoglyph?s and lines, ...

This paper presents an application of photogrammetrical methods for called IBMR (image based modeling and rendering) in comparison with using of several laser scanning techniques. At the CTU (Czech Technical University) in Prague, Laboratory of Photogrammetry, new methods of 3D objects documentation is tested as the long term project. There are two main approaches in documentation: precise documentation by several techniques as precise close range stereo пїЅ fotogrammetry and laser scanning or simple documentation...

There are a lot of traces of wars or military activities throughout the Czech Republic. You can find fortifications from Roman times to the Cold War. In 2009, a big project started in the Czech Republic пїЅ aerial laser scanning of the whole national territory. It was finished in 2013; since this year there has been a possibility to use very precise digital terrain models (DTM), a new face of the landscape mainly in forested areas, derived from aerial laser scanners and INS instruments. For archaeology, the use of...

Remotely Piloted Aircraft Systems (RPAS), which have become more popular in recent years, can obtain data on demand in a short time with a resolution within centimeters. Data collection is environmentally friendly and low-cost from an economical point of view; of course it is best for small areas, such as square kmпїЅs, only by using winged drones or in a few hectares by use of multi-copters. Both types have their advantages and disadvantages. Our laboratory of photogrammetry has, since 2012, focused on using RPAS...
