To show a portion of the Earth's surface on a map, the scale must be sufficiently adjusted to cover the objective. The extent of reduction is expressed as a ratio. The unit on the left indicates distance on the map and the number on the right indicates distance on the ground. Maps are made at different scales for different purposes.
measure distance on a map? Use the scale bar found at the bottom of every NRCan topographic map to determine distances between points or along lines on the map sheet.
OnLine tool for measuring distance & area on a map.
DISTANCE Maps are drawings, which reduce the entire world or a part of it to fit on a sheet of paper. Or we can say maps are drawn to reduced scales. But this reduction is done very carefully so that the distance between the places is real. It can only be possible when a small distance on paper
30 lis 2021 · Maps are the basic tools for the visualization of geographic data and understanding their spatial relationships. A map is a simplified representation of the whole or part of the earth on a piece of plane surface or paper. It is a two-dimensional depiction of the three-dimensional earth.
•Definition of scale: it represents the ratio of a distance on the map to the actual distance on the ground. This is important when we plan a tour. •Example: 1:50 000 means 1cm represents 50 000cm or 0,5km in reality. Ratio is usually indicated on a line scale.
Enjoining places with same height by drawing contour lines on a given map is called drawing a contour map or interpothen of contours. While drawing contours, following points are to be kept in mind: (1) Meaningful contours maps may be drawn if height of maximum places is provided in a map.
