The famous Peruvian cultural heritage is one of the most famous cultural heritage sites in the World. In the Nazca desert plain, there are well known structures called geoglyphs. For about 40 years of her life, Maria Reiche (1903-1998) from Dresden investigated these structures. The Laboratory of photogrammetry of the Czech Technical University in Prague (CTU), Faculty of Civil Engineering has been focused on cultural heritage project for a long time [10], [11], [14]. From 2004 we have collaborated with the University of Applied Sciences in Dresden, which is involved in project "Nasca" on documentation of geoglyphs and other objects of valuable cultural heritage. But in Peru, there are not only geoglyphs. A lot of other very interesting cultural and archaeological sites can be found in Peru. At CTU, we started a new project focusing on archaeo-astronomical orientations of important objects in Peru. This new project is a part of the long term "Nazca" project. A lot of mysterious objects in Peru (like in other parts of the world) are astronomically oriented. In Peru the orientation of religious objects is mainly sun-oriented. It means that geometrical axis of important objects are oriented with 66 degrees or 114 in azimuth. These azimuthal orientations are related to winter or summer solstice. Satellite imaging is well known as a useful tool in many scientific disciplines and various applications. In the last decade, new generation of satellite data are at disposal. Our analysis is based on personal measurements from four international expeditions (German Czech) to Peru (20042012), [14] and investigation of Google Earth technology. Google Earth, with its free access, is now - thanks to increasing resolution and precision - a suitable scientific tool [5], [13]. It improves the visualization and dissemination of scientific data and opens doors to new discoveries. It is possible to measure astronomical orientations of historical object, geoglyphs or pyramids without visiting these places. Satellite images and Google Earth can also inform us about the new archaeological locality. We find that Google Earth and satellite data can significantly save time and provide resources to researches: before, during and after field works and measurements [12]. This article is about undertaken measurements and analysis of valuable historical objects in Peru by using satellite data and direct measurements in Peru.
