Starting Point

The starting point of a survey is also called the starting station and is numbered 0 + 00. The next station is 100 feet farther away and is numbered 1 + 00. The next station, which is 200 feet beyond the starting point, is then numbered 2 + 00, and so forth. All stations that end with 00 are called full stations. Figure 32 shows that stations may be abbreviated STA on the stakes.

On sharp curves or on rough ground, the stakes may be closer together than on the straightaway. Stations located at a distance shorter than 100 feet from the preceding station are known as plus stations, such as 3 + 25, 3 + 53, and 3 + 77. These examples are plus stations of station 3 + 00.
