Use of Anaglyphs as an Alternative for Stereoscopic Pratics on Remote Sensing

Abstract

Aerial Photogrammetry is one of the most used implements on remote sensing. One of the most common resorts for analysis in this area is the stereoscopy, which consists of visualization on 3 dimensions of the aerophoto through the use of a stereoscopic pair. There are three main stereoscopic visualization methods: trough anaglyphs, polarization and with a stereoscope. Despite the stereoscope still the most used method, the anaglyph may be an alternative for studies using stereoscopic techniques, with the advantage of using cheaper materials and having the possibility of application on Geographic Information Systems, allowing more cleared analysis with the tools of this kind of software, being very useful when applied on the education, turning the teaching process more dynamic.
