This course discusses Topographic and Planimetric Mapping as covered in the Oklahoma Minimum Standards of Practice adopted in January 2019. The purposes of the standards are covered and identification of documents outside of the standards, such as the FGDC Geospatial Positioning Accuracy Standards. How accuracy statements are to be stated are covered in the course, again, referring sometimes to documents that are referred to in the standards. Discussion of horizontal and vertical accuracy and how to test for compliance are then presented. Details of the information to be shown, such as control point data, data sources and similar data are also covered. The course concludes with examples of certifications. The PDF provided with this course, in addition to the PowerPoint slides, also includes the text of the standards which are incorporated in the Oklahoma Administrative Rules Title 245, Subchapter 13.
Objectives:
- Learn about the definitions relating to reading and implementing the standards in the mapping that is generated
- Understand the details of horizontal and vertical accuracy requirements together with example tables relating scale to the appropriate accuracy statistic.
- Ability to apply the standards to the information to be included or attached to an applicable map or reported created under these standards.
- Be able to generate the required certification relating to control and topographic surveys.

I believe the answer to the question, "Using NSSDA tables, if the mapping is at 1:1,200 scale, the positional accuracy in the horizontal plane" should be, "Must be a little more than 35 feet". The reason being is that 1:1,000 is 34.6 feet and 1:2,000 is 69.2 feet; Therefore, 1:1,200 must be 41,5. There's no way it can be 3.5 feet. That's for 1:100 scale
concise and interesting
