In the first publication presented at the ISPRS conference in Dresden in 2006, I showed the first attempts to use spherical panoramas, as a collection of measurable directions taken with a theodolite for arquitectural surveys. It was necessary to make vertical the axis of the sphere of the panorama such as for setting up the theodolite. In the next work at the Sifet 2007 conference in Arezzo, I presented the first successful architectural surveys. The limitation of the technique is the absence of stereoscopy and so far any automation in plotting. Spherical Photogrammetry´s benefits include acquisition speed, document completeness, and cost-effectiveness. At the 2015 Taipei CIPA conference, I was honored with a career prize, with the motivation "For the unbelievable number of documentation surveys carried out in every part of the world." Following the publication over 10 years, one can see the evolution of the technique with which I made hundreds of surveys all around the world, here shown, then developed by my students, to whom this book is devoted.

Fangi, Gabriele
Gabriele Fangi was Professor of Geomatics at the Polytechnic University of Marche, Ancona, Italy. He developed a new photogrammetric technique called Spherical Photogrammetry, which is particularly suited to the survey of architecture, the main feature is the speed of documentation and the simplicity of the equipment.
