This report provides a description of the design and implementation of a dynamic, web-based Trigonometric Coordinate List (Trig List) for the University Engineer’s Office, The Ohio State University. Traditionally, a Trig List publishes pertinent monument data, such as Northings, Eastings, elevations and corresponding datums, along with text based point recovery information. This modernized Trig List, aside from publishing the traditional monument data, will also provide non-traditional data and detailed station recovery notes. Non-traditional data items include intervisibility between points and GPS availability if known. Station Recovery Notes will include site sketches, vicinity maps, and annotated digital photographs. Textural data input into the system and all data retrieval from the system will be accomplished through a web browser, versus the traditional database approach. This approach was selected due to its widespread availability and the small learning curve required of its users. By providing a user-friendly and well-known interface, it is anticipated that the Modernized Trig List will be utilized frequently, thus solidifying its own longevity. Through use, and subsequent refinement, the web-based system is proving to be an excellent platform for data distribution and maintenance. One positive unpredicted side effect is the ability to utilize the system as a management and planning tool for the maintenance and future densification of the Campus Control Network.
