Parallax - Study guides, Class notes & Summaries

Longitude - Meridian Latitude - Parallels Units of Meridians and Parallels - Degrees 1 Degree of latitude - 112 km/70 miles 1 Degree - 60 minutes 1 Minute - 60 arc seconds Prime Meridian - Greenwich meridian Geostationary Satellites - Stationed at 0 degrees celestial latitude and each has a constant celestial longitude Parallax - The effect whereby the position or direction of an object appears to differ when viewed from different position

Feature Search - ️️Search for a target defined by a single attribute - If salient feature (different) number does not matter - If the feature is different enough, it becomes easier to find the target - Reaction Time for feature searches does not change with set size Monocular Depth Cues - ️️Represented in 2D and observed with one eye 1. Texture Gradient (closer, larger grains, farther apart, away - smaller grains, closer together) 2. Relative Size (closer - bigger, away - smaller)...
