These include satellite images, traffic surveys, and more. Urban planners and engineers are able to derive elevation data from a variety of sources. Elevation data are then processed by models which determine elevations based on algorithms and statistical analysis. In the case of natural hazards such as elevations of mountains, sea levels, or tectonic movements, the elevation data are often recorded in meters and later converted to a more usable format appropriate to the specific hazard. Digital elevation models are based on measurement techniques that allow for the recording of elevation at different scales. Typically, the most common applications relate to natural hazards (for example, flooding, or snowfall). For example, a single vehicle on a highway does not need to be shown using contour lines to show the exact location of each feature.ĭigital elevation models (DIMs) can be applied to any range of elevation data. In the case of airplanes or other relatively slow-moving vehicles, this may not be necessary. This type of elevation map is typically produced for a limited range of space and cannot reveal long-hidden elevations. Most experts use contour lines to show changes over long periods, rather than short ones.Īnother technique used to produce an elevation map is a grid map representation. Contour lines can be used to determine the location of high points (hydrothermal hot springs, for instance), or to highlight regions of extreme topography or change elevations in elevation over time (floodplains). In the case of an airplane, the height of an airplane’s altitude is derived from the surface elevations above sea level. Contour lines show where elevations (also called elevations) exceed a specific height. Experts in the field to evaluate the results of surveys and map design using a variety of measurements, including surface elevations, contour mapping, and GPS data.Ī contour map is more detailed than elevations. The elevation data is then processed to provide final elevation map results. These measurements are recorded in a database that is then computerized. Survey techniques often provide more information about land surface elevations than other technologies.Ī digital elevation map uses elevations of land surfaces to provide detailed topographical information. Topographic surveys can take longer and require higher precision, but they typically cover large areas. Each of these techniques has its advantages and disadvantages. Surveying methods include topographic, survey, photogrammetric, electronic mapping, and satellite mapping. Map accuracy depends on several factors, including user error, measuring equipment errors, terrain, and topography factors, and the passage of time. A good map can make the difference between deciding where to go for a hike versus choosing a more desirable route, and it can tell you whether you should stay or go home early from your trip.ĭigital elevation maps (DAMs) are used for a wide range of applications, including the management of resources and land use. Topography concerns the nature and shape of the Earth’s surface, which is why maps have been among the earliest tools to document these changes. Maps are an important part of outdoor gear for a variety of reasons.
