The contours are offered as an additional layer on DWG and DXF files. Supplementary lines appear as dotted lines, indicating flatter terrain.Typically one index line occurs for every five intermediate lines. ![]() ![]() Intermediate lines are the thinner, more common, lines between the index lines.This tells you the elevation above sea level. Index lines are the thickest contour lines and are usually labeled with a number at one point along the line.There are 3 kinds of contour lines you’ll see on a map: intermediate, index, and supplementary. Shallow slope (the contours are spaced apart) Steep slope (the contours are close together) For example, several contour lines spaced close together would indicate steep terrain, while lines spaced far apart would indicate a gentler slope. If each line represents an equal point of elevation, then any change in elevation would lead to inconsistent line spacing. When checking quickly a topographic map you can immediately know if a landscape is mountainous or flat. The contour lines we are using today came into popular use in the mid-1800s along with the rise of resource extraction industries like mining and logging. It would be thousands of years before cartographers could chart large areas of terrain with any real accuracy. The first known maps to include geographical features were found in Ancient Rome. Specifically, a topographic map represents the three-dimensional landscape of the Earth within the two-dimensional space of a map. Topographic maps use a combination of colors, shading and contour lines to represent changes in elevation and terrain shape. A map with contour lines on it is called a topographic map. Topography is the study of the geographical features of a landscape. In addition to backpacking and hiking, countless other professions use them - land surveyors, architects foresters, engineers, miners, geologists, hunters and more. This information can be helpful when selecting a hiking route. #Contour lines in art example downloadDownload 1m Contours of the UK for CAD software hereĭiagrams provided by Encyclopaedia BritannicaĬontour lines are critical to understanding the elevation profile of your terrain or a particular land formation. Contour lines are pictorial, meaning they do not exist on the ground. Understanding contours is a skill that will allow you to look at a map and picture the hill, with depressions for streams, hills and thin mountain ridges, etc. In other words, contour lines show the topography of the land. They're useful because they illustrate the shape of the land surface on the map. Contour lines show elevation and the shape of the terrain. The following drawings represent an example of this type of meditative contour drawing that will become a tool that I could then take to my large scale oil paintings of gardens.Contour lines are the faint red-brown lines drawn on a map connecting points of equal elevation above sea level, meaning if you physically followed a contour line, the elevation (height of the land) would remain the same. And following Hockey’s thinking my eyes could ache after I had finished a large drawing with definite lines and spaces. When I followed along the outer edges of the petals and stems my mind became quickly meditative. My contour lines became an exercise of intense concentration and observation. I often sat in the garden my husband took exceptional care of and slowly and deliberately drew the lines of flowers. My drawings do make me see things more clearly. It was the process that was important.ĭavid Hockney, the British artist, once said “Drawing makes you see things clearer, and clearer and clearer still, until your eyes ache.” Hockey’s words resonate with me. Maybe, just maybe these lines made me see what the professor was saying. I am not sure where they came from but there was a need to make marks on a white surface. My lecture notes and the pages of the text book soon filled with definite, contour lines from somewhere deep inside the recesses of my mind. My hand would sub consciously grasp a pen. Thinking back to my university days I often picked up the rhythm of the professor’s voice during lectures. Every inch of those walls were covered with lines, squiggles and circles. At night I drew all over my bedroom walls. I used leftover blackboard chalk on the schoolyard pavement. Most days after school I drew on my grandfather’s thin yellow typing paper with a stubby pencil and an eraser that did not erase. I drew in the wet sand on the beaches of Okanagan Lake. Some of my earliest memories are of drawing. ![]()
