Surveying Software

The following software is available for download for use is supporting Survey Deliverable requirements to the New Orleans District. None of these program are contractually required for use. They are instead offered as a convenient possible means of producing a deliverable in a certain format.

Corpscon is a USACE-developed Windows-based program which allows coordinate conversion between Geographic, State Plane, Universal Transverse Mercator (UTM) and US National Grid systems on the North American Datum of 1927 (NAD 27), the North American Datum of 1983 (NAD 83) and High Accuracy Reference Networks (HARNs). Corpscon uses the National Geodetic Survey (NGS) program library NADCON to convert between NAD 27, NAD 83 and HARNs.

Corpscon performs vertical conversions to and from the National Geodetic Vertical Datum of 1929 (NGVD 29) and the North American Vertical Datum of 1988 (NAVD 88). Vertical conversions are based on the NGS program Vertcon. However, use of Corpson for vertical datum transformations in NOT AUTHORIZED for any work in south Louisiana.

Microstation is a packaging of appropriate MicroStation seed files, cell libraries, and MDL programs useful for placing XYZ data into DGN files with appropriate labeling and use of AEC CAD standards. PUT.MA is the mdl program. It is packaged as a MicroStation Version 7 file and a Version 8 file news MicroStation installs.

A menu driven coordinate geometry software package used to compute range end points, intersections, curves, etc. The package uses the EM format. 

Survey Drivers
A tool for designing, implementing, and maintaining a system for managing the standardized geospatial survey file formats of the U.S. Corps of Engineers, including, but not limited to the national standard published in the Engineering Manual, EM1110-2-1005, and all formats used internally by the New Orleans District such as LMN830 and Traverse Computation files. 

Survey Checker
Survey Checker (Formerly EM Checker) is a python command line tool that is part of Survey Drivers.

NAVD88(2004.65) PBMs in Google Earth
Plots the NSRS benchmarks referenced to NAVD88(2004.65) in the Google Earth environment with links to the NGS datasheets.

NAVD88(2009.55) PBMs in Google Earth

Plots the NSRS benchmarks referenced to NAVD88(2009.55) in the Google Earth environment with links to the NGS datasheets.

HSDRRS PBMs in Google Earth

Plots benchmarks established for LPV and WPV projects, referenced to both NAVD88(2004.65) and NAVD88(2009.55), in the Google Earth environment.

Survey Pack
Survey Pack - (Survey Pack software requires that ANSI.SYS be loaded onto the PC drivers) Survey Pack has tools for performing various COGO functions and creating the CSAR Baseline Format that is preferred by New Orleans District.

Survey Pack is a zip file with several older COGO-type programs that still have utility for USACE support. Primarily a program that will create the New Orleans CASR format for presenting baseline computations.

Note: Survey Pack software requires that ANSI.SYS be loaded into the PC environment to use an ANSI escape sequence to control the screen and keyboard for the MS-DOS subsystem. Use the systemroot\System32\Config.nt file, or the equivalent startup file Type the following in your Config.nt or equivalent startup file: device=c:\winnt\system32\ansi.sys
