Detailed topographic representations utilize elevation contours, where lines connect points of equal altitude. A map of this nature, with contours spaced at two-foot intervals, provides a highly granular depiction of terrain in a specific geographic area. This precise level of detail allows for accurate assessment of land slope, volume calculations, and identification of subtle topographic features within Montgomery County, Maryland. Such maps are distinct from those with coarser contour intervals, such as five or ten feet, which provide a less refined depiction of the land surface.
This level of geospatial information is vital for numerous applications. Civil engineers rely on these maps for site design, stormwater management, and infrastructure planning. Environmental scientists utilize the detailed topographic data for watershed analysis, wetland delineation, and assessing potential erosion hazards. Developers employ these maps to optimize land use, minimize environmental impacts, and ensure compliance with local regulations. The historical availability and ongoing maintenance of accurate elevation data contribute significantly to the responsible development and environmental stewardship of the region.
