Jun 19, 2024 · Maps – Calculating a curved line distance? Calculating a curved line distance on a map involves measuring the length of the curved line using appropriate mathematical techniques such as trigonometry or geometry. This helps determine the actual distance between two points on the map, accounting for the curvature of the Earth’s surface.
Curved lines as straight-line segments. a. The curved line. b. A series of straight line segments that approximate the distance. c. Shorter, additional straight-line segments to more accurately measure the distance. If you are using a hard-copy map, an alternative method of measuring curved lines is to use an opisometer (also called a map ...

Aug 18, 2022 · Many maps of land areas have series of curved lines, called contours, that represent the topography of the area. Such a map is called a topographic map. A contour is a horizontal curve that’s the locus of all points on the map with the same elevation (Figure 3-35). A good way to understand the concept of contours is to choose a series of ...
Straight vs. curved. By default, the line shows the shortest distance, which means curved lines as it follows the curvature of the Earth surface. Setting shortestDistance to false will make the lines perfectly straight. More about shortest distance setting. Setting initial zoom. Any zoom level and position can be set using map’s homeZoomLevel ...
Sep 24, 2014 · There is a common misconception that if you were to walk in one direction without wavering and then drew a line of all the places you stopped it would appear as a curve on a map. While it is true you would actually walk in a curve, on a Google Map which uses what is called a Mercator projection, the line would actually be straight.

Jun 28, 2022 · A transit line is a straight line that intersects your current position and two visible landmarks. Transit line LOPs can be used to orient a map, or sight a bearing without using a compass. The two landmarks I observed were a small unnamed topographical bump (foreground) and the very prominent north face of Long’s Peak (background):
