Title 10 - DEPARTMENT OF NATURAL RESOURCES
Division 30 - Land Survey
Chapter 4 - First and Second Order Horizontal and Vertical Control
Section 10 CSR 30-4.040 - Acceptance and Publication by DNR

(1) The following information will be submitted for each control survey that is to be evaluated for inclusion into the Missouri Geographic Reference System (MO GRS) as a first or second order station.

(2) A report shall be submitted for each project and shall be signed and sealed by the surveyor or engineer in responsible charge. The report shall be the main source of information for judging whether or not the stations should be accepted as MO GRS stations. It shall be the responsibility of the surveyor or engineer to supply sufficient information in the report to facilitate inclusion of the stations in the MO GRS.

(3) The report shall contain a clear description of the survey procedures and equipment used in the field. This includes, but is not limited to the information entered into the field log and auxiliary information such as logistics, preanalysis and satellite selection results (if Global Positioning System (GPS) survey), personnel involved, and difficulties encountered.

(4) In the report there shall be a clear description of the procedures used in the office. This includes, but is not limited to, computer software and hardware used to process observations, options used (if any), data editing performed, source of orbital data (if GPS survey), parameters adjusted and held fixed, results of self-validation and any difficulties encountered.

(5) The following shall be included for GPS surveys. The version number and date of the GPS software used must be reported. For GPS surveys, the surveyor must also specifically report the baselines rejected for the project. All parameters used for any coordinate transformations shall be presented and any scaling of the covariance matrix by the surveyor must be described in detail. If the covariance matrix has been scaled, the scale factor used must also be presented. These results must be reported for all single base line and network solutions. Statistical testing of the survey results from the network solution, including analysis of variance factors, semi-major axis of 2-d (horizontal) or 3-d ninety-five percent (95%) relative confidence regions between all directly connected pairs of points, residuals and residual outliers shall be provided. In addition, the results of any self-validation checks must be reported, including but not limited to, comparisons of any repeated single base line solutions.

(6) For traverse surveys, all field data used to determine directions, distances, azimuths and elevations, the adjustment calculations shall be submitted along with the name of the software used in the adjustment. The data submitted shall show the final results of the adjustment and the error analysis.

(7) Only those stations meeting the requirements of 10 CSR 30-4.030, 10 CSR 304.040, 10 CSR 30-4.050 and 10 CSR 304.060 will be accepted for publication in the MO GRS.
