WebMapping is a crucial part of Earth science. Topographic maps represent the locations of geographical features, such as hills and valleys. Topographic maps use contour lines to show different elevations on a map. A contour line is a type of isoline; in this case, a line of equal elevation. If you walk along a contour line you will not go uphill ... WebOnly a few series are in common use. The 7 1/2-minute quadrangles, which have a scale of 1:24,000, are the most popular. These detailed maps are supplemented by the 1:250,000-scale series. A third series, the 15-minute quad at 1:62,500, was popular but discontinued by the USGS for mysterious reasons (probably because the detailed 1:24,000 maps ...
WebA re-entrant (international) or draw is a terrain feature formed by two parallel ridges or spurs with low ground in between them. The area of low ground itself is the draw, and it is defined by the spurs surrounding it. Re-entrants are similar to valleys on a smaller scale; however, while valleys are by nature parallel to a ridgeline, a re ...
