What technology does Herrick & Salsbury, Inc., use?

The technology available to land surveyors has grown incredibly in the last couple of decades. In the 1960s, when Herrick & Salsbury, Inc., was started, theodolite survey instruments and 100-foot long steel tapes were the technology of the day. In the 1970s came the advent of the first stand-alone microcomputer for coordinate geometry. Herrick & Salsbury, Inc., was an early adaptor, purchasing an Olivetti P-101 in 1970 for the sum of $3,200. The Olivetti P-101 had no data storage device. When the computer was shut off, all the data in memory was erased. In 1971 a model P-602, which included a magnetic tape drive for data storage, was purchased for the grand sum of $6,577.50. Later in the 1970s, a Hewlett Packard distance meter was purchased. This machine measured distances up to two miles using laser measurements. It was heavy and bulky but was a huge leap in technology. Three-hundred-foot steel tapes became common. In the 1980s, Herrick & Salsbury, Inc., purchased the first of many total stations, which combined angular measure and distance measurement all in one unit. In the 1990s, GPS came along, first as large, bulky units that had to be stationary for an hour or two at a time just to measure one position, then backpack-type units with one- to two-meter accuracy which was used for forestry type surveying. The 1990s also brought the advent of computer-aided design (CAD), using desktop computers to draw survey plans. Since then, GPS has really matured to the point where we use it almost every day and the functionality has grown as quickly as mobile computing devices have grown and matured, as the mobile computing device and 4G cellular communication are key to utilizing GPS on the fly.
