This contribution deals with the topic of Lines and Geoglyphs in Peru (Nasca, Palpa) and their changes through time. It aims to gather and analyze image data from historical sources as well as from the Nasca expeditions of 2004 – 2016. In the time before the geoglyphs' popularisation 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. Some geoglyphos and lines were damaged or destroyed by tourists, others by civilization activity (garbage, air polution, constructions, geoglyphos and lines questionable renovation etc.) and of course by climate changes. The Czech Technical University, faculty of Civil Engineering, dept. of geomatics collaborated for a long time with HTW Dresden and the Dr.Maria Reiche Association on the research and documentation of the cultural heritage in Peru, mainly in the Nasca project. This project, founded in 1993 in Dresden is focused on the perfect documenation and research of the main theories about the origin of geoglyphos and lines near the cities of Nasca and Palpa. In our project, we collected a lot of historical photographs such as photographs taken during our expeditions to Peru berween 2004-2016. In the GIS system, we analysed time changes on most of the known geglyphos and lines systems. This paper describes the process of the work with images and background data. The last part includes the evaluation of the final photo plans and deals with an analysis of changes. The last part also contains a discussion concerning the results of the work and general thoughts about geoglyphs and lines. The main aim of the paper is to contribute to the preservation of the thousands year old lines and geoglyphs which are constantly and irrevocably damaged by both man and nature.
