We have performed everything from traditional horizontal control prior to the advent of GPS, to high precision horizontal GPS, and even assisted the National Geodetic Survey in developing standards for performing high precision Vertical GPS surveys. Map Checking Understanding / Scope: In general, all map checking follows a similar work flow. Unlike many standard surveying procedures, map checking always follows a checklist. This ensures that all items with which a particular agency or jurisdiction is concerned are adequately reviewed, and that no critical items are overlooked. In general the checking process goes as follows: • The process starts at the top of the title sheet, where items such as the date of the survey, the tract number, and acreages are checked. The next step is to check the legal description of the property and ensure that it matches the title report provided. Then on to dedications and 5150 E.
