Influencing the Perception of Contour Lines
Cartographic Journal, The, 1981AbstractTwo possible causes of the failure of map users to successfully interpret relief forms from contour maps are Gibson's texture gradient effect which may give false depth cues; and, the expectancy or prior set developed from previous experience by the map reader.

Automated placement of supplementary contour lines
International Journal of Geographical Information Science, 2019Supplementary contour lines are placed between regular contour lines to visualize small but important forms that regular contour lines are unable to show.

Contour line extraction with wireless sensor networks
IEEE International Conference on Communications, 2005. ICC 2005. 2005, 2005An algorithm to extract contour lines using wireless sensor networks is proposed for environmental monitoring in this work. In contrast to previous work on edge detection that is primarily concerned with the region of a certain phenomenon, contour lines ...

Description and Generalization of Contour Lines [PDF]
, 2019 A contour line (also isoline, isopleth, or isarithm) is a line on a map joining points of equal height or depth above or below a level, usually mean sea level. It is often just called a “contour”. Each contour is a closed curve (Veregin 1999, 2000; Cheung and Shi 2004).

Contour Line and Geographic Feature Extraction from USGS Color Topographical Paper Maps
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2003This paper presents a method for the extraction of contour lines and other geographic information from scanned color images of topographical maps. Although topographic maps are available from many suppliers, this work focuses on United States Geological ...

Journal of Navigation, 1967
Contour charts are of great value ‘providing’, as Hughes says, ‘the navigator with a quick and sure means of comparing the echo sound record he has just made with the variations in contour and so enabling him actually to plot his line of position by soundings’.

Real Time Contour Line Visualization of an Object
Japanese Journal of Applied Physics, 1974Abstract Two methods of real time observation of contour lines of an object are discussed and experimental results are given. An analysis of the visibility of these contour fringes is presented and some experimental limitations are considered.

An ASIC architecture for contour line filtering
ICASSP-88., International Conference on Acoustics, Speech, and Signal Processing, 2003Proposes an application-specific IC architecture for implementing a contour line filter for a real-time fingerprint recognition system. The architecture demonstrates the fact that a library-based set of data-path modules which are steered by powerful, synchronized controllers can result in real-time performance on a single chip, even for a complex ...

Approximating Complex Surfaces by Triangulation of Contour Lines
IBM Journal of Research and Development, 1975An algorithm is described for obtaining an optimal approximation, using triangulation, of a three-dimensional surface defined by randomly distributed points along contour lines. The combinatorial problem of finding the best arrangement of triangles is treated by assuming an adequate objective function. The optimal triangulation is found using classical
