Designed to work with standard dsdatasheet files, this program allows the user to download and update data via the web; create horizontal and vertical geodetic control listings; view, print, and export datasheets and digital photos; create databases of geodetic control, and much more.

Complete built-in help is provided, including instructions for recovering, positioning and photographing geodetic control points. Another tool from Malcolm Archer-Shee. USGG2003 is a gravimetric geoid model, and is an update of the G99SSS model.

An on-line interactive version is also available from the. Converts NAD 27 State plane coordinates to NAD 27 geographic positions (latitudes and longitudes) and conversely. Includes defining constants for all NAD 27 plane coordinate zones. This horizontal time-dependent positioning software program allows users to predict horizontal displacements and/or velocities at locations throughout the United States and its territories. This software also enables users to update geodetic coordinates and/or observations from one date to another.

An on-line interactive version is also available from the. Interpolates binary GPS orbit files with a record length of 52. Comprises four programs - INVERSE which computes the geodetic azimuth and distance between two points, given their geographic positions; FORWARD which computes the geographic position of a point, given the geodetic azimuth and distance from a point with known geographic position; and the three-dimensional versions of these programs - INVERS3D and FORWRD3D - which include the height component. These programs are based on the April, 1975 by T. An on-line interactive version is also available from the.

Determines the loop misclosures of GPS base lines using the delta x, delta y, delta z vector components computed from a group of observing sessions. Estmates the leveled height difference between two bench marks by removing the orthometric correction from the differences of published heights. Computes geoid height values for Mexico.

Suggest you read before obtaining software. Computes and verifies classical horizontal field observations (angles and distances), and formats these data to conform to Blue Book specifications. MTEN4 does not adjust field observations, but performs certain field check computations such as triangle computations, distance reductions, and trigonometric height computations. MTEN4 allows four-digit station numbers and new position codes set forth in the Blue Book. Program na2vbbk performs file format conversion from a Leica/Wild NA2000/3000 series digital level output file format to a NGS vertical bluebook format. Minimal data checks are performed. NOTE: Program na2vbbk does NOT verify that field observations were within FGCS tolerance limits nor does it compute the partial refraction correction.

It should only be used when upper and lower thermistor probe temperatures are OBSERVED at each level instrument setup. E Transforms geographic coordinates between the NAD 27, Old Hawaiian, Puerto Rico, or Alaska Island datums and NAD 83 values.
