Seamless elevation data are available for the conterminous United States, Hawaii, Alaska, and the U.S. territories, in three different resolutions1/3-arc-second, 1-arc-second, and 2-arc-second. The conventional way to extend and establish survey control on a project would be to use a total station. The data shown can be extracted from the project network control survey and historical control data, or reflect assumed datum. Prominent features on buildings such as the tip of a church spire or a chimney stack are also used as reference points for triangulation. 2.

So he can do this himself instead of having surveyors come out and charge him $500 for half a days work. Horizontal control surveys. Establishing survey control is one of the first things a surveyor would do on a new site. A good ground control point is one that is visible and usable for surveying and setout on a site, and is stable and reliable to use. This map product series, named US Topo, is modeled on the now historical USGS 7.5-minute (1:24,000 scale) topographic map series produced and printed by the USGS from 1947 to 2006. A control survey is the process of establishing survey control points that can be used to provide surveying services on a land development or civil construction project.
