1. Chapter 6 Photogrammetry

2. n Perspective (central) projection: aerial photographs vs. maps n Co-linearity equation n Photogrammetric orientation n Digital photogrammetry n Photo-interpretation Introduction

162. Photo-interpretation n Basic: tone/color n 2 nd order (geometric arrangements of tone/color): size, shape n 2 nd order (spatial arrangements of tone/color): texture, pattern n 3 rd order (positional elements): site, association n 3 rd order: height, shadow

163. Elements of Image Interpretation  Primary Elements  Black and White  Tone Color  Stereoscopic Parallax  Spatial Arrangement of Tone and Color  Size  Shape  Texture  Pattern  Based on Analysis of Primary Elements  Height  Shadow  Contextual Elements  Site  Association
