What is a contour map?


“A contour line represents the tracing of one constant elevation above or below a certain datum. In other words, every point on any one contour line is at the same elevation throughout that contour line. Although the datum may be an assumed point of elevation accommodating the job, it is more often based upon Mean Sea Level”

-Gurdon Wattles, Survey Drafting

Need for contour maps Storm water drainage and spill prevention

plans regulated by North Dakota Department of Health

Storm Water Pollution Prevention Plan (SWPPP) “Provide a site map showing … drainage patterns, including flow direction, dividing lines, existing grade and final grade”

Support Environmental Engineers managing erosion and sediment controls

Approach


Identify software and devices to use Establish proper differential correction

technique Verify elevation accuracy of Trimble Geo XH Develop surveying practice for contour

mapping Create work plan Deploy field crew Align system settings with local geodetic

control Maintain data management of collected

information Post-process Produce maps
