The distinctive characteristic of a topographic map is the use of elevation contour lines to show the shape of the Earth's surface. Elevation contours are imaginary lines connecting points having the same elevation on the surface of the land above or below a reference surface, which is usually mean sea level. Contours make it possible to show the height and shape of mountains, the depths of the ocean bottom, and the steepness of slopes.
Our TopoGraphical Sheet Finder Application is a very useful to find Topographical sheet by putting the Geo Co-ordinates. We have developed the India's First Topographic Sheets and Maps Finder application
topographic map identifies numerous cultural and natural ground features which can be grouped into the following categories: CULTURE: roads, buildings, urban development, boundaries, railways, power transmission lines; WATER: lakes, rivers, streams, swamps, rapids; RELIEF: mountains, valleys, slopes, depressions; VEGETATION: wooded and cleared areas, vineyards and orchards; TOPONYMY: place names, water feature names, highway names. Refer to the legend on the back of an NTS map for a complete listing of all features and their corresponding symbols. Information along the map borders and on the back of the map provides valuable details to help you understand and use a topographic map. For example, here you will find the map scale and scale conversion, the legend, and the year the information on the map was last updated.
