Projects Survey Control Points
The purpose of this data set is to keep all the pertinent information for TDOT's Project Survey Control Points organized in a searchable database and display the location of those points on a map to make them easy to find.
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This data set contains the attributes of control points set for the surveying and construction TDOT projects. These attributes include the County that each point is in, the pointname, filename, the year it was set, the condition that it's in. It contains the coordinates of the point in a variety formats such as global and state plane. I provides the coordinates in different units such as US Survey Feet and Meters. It contains the horizontal and vertical datum , geoid, local datum adjustment and scale factor that was used in setting each point. It contains the names of people who set the point, described it and processed it's location. It contains the description of the monument that was set in the field and to reach and reference information for locating the point in the field. For older points in this data set there is backsight information, but newer points will not include backsight info.</SPAN></P></DIV></DIV></DIV>

FILENAME
Filename
String

0
The name given to a group of control points on a project. In most cases there would be a corresponding project number, but these filenames are usually established before a project number is assigned. Typically the filename starts with a 2 letter abbreviation of the County followed by the state route number then a dash followed by a 2 digit number to distinguish it from other projects in that county along that route.

CONDITION
Condition
String
10
0
0
Condition of the monument. If the monument was set in the past 10 years and it's coordinates still give a reliable location of the center of the monument to less than 0.1 US Survey Feet then it is considered in Good Condition. If the monument was set over 10 years ago and has not been checked for it's reliability then the condition is Unknown. If the monument has moved and it's coordinates no longer give a reliable location to less than 0.1 US Survey Feet it is considered Disturbed. If the monument can no longer be found and there is good reason to believe it no longer exists it is considered Destroyed. Field crew will notify their supervisors of the conditions of monuments as they use them. Domain (Good, Unknown, Disturbed, Destroyed).
