Accuracy Standards for Land Survey

Accuracy Standards for Land Survey 3 hour PDH online course is a part of the Land Surveying category courses. This course sets forth accuracy standards and other related criteria that are recommended for use in large scale site plan topographic surveys for engineering and construction purposes. These standards relate to surveys performed to locate, align, and stake out construction for projects, e.g., buildings, utilities, roadways, runways, flood control and navigation projects, etc. In many cases, these engineering surveys are performed to provide the base horizontal and vertical control used for area mapping, GIS development, preliminary planning studies, detailed site plan drawings for construction plans, construction measurement and payment, preparing as-built drawings, installation master planning mapping, future maintenance and repair activities, and other products. Most engineering surveying standards currently used are based on local practice, or may be contained in state minimum technical standards.

This course is intended for civil engineers and professional land surveyors wanting to learn about accuracy standards for land surveys.

Learning Objectives

This online PDH course teaches the following specific knowledge and skills:

• Learn about general surveying and mapping specifications. for construction plans, maps, facility plans, and CADD/GIS databases;
• Learn about published surveying and mapping accuracy standards, such as the American Society for Photogrammetry and Remote Sensing (ASPRS), the American Society of Civil Engineers (ASCE), the American Congress on Surveying and Mapping (ACSM), and the American Land Title Association (ALTA);
• Learn about quality control (QC) practices for contracted surveying and mapping work to be performed by a contractor;
• Learn why, when practical, feasible, or applicable, projects should be adequately referenced to nationwide or worldwide coordinate systems directly derived from, or indirectly connected to, GPS satellite observations;
• Learn how engineering and construction surveys are normally specified and classified based on the horizontal (linear) point closure ratio or a vertical elevation difference closure standard; and
• Find out about construction survey procedural and accuracy specifications developed by recognized industry and local practices.
