Software for processing level data

Translev This program facilitates the process of edtiting, formatting and checking digital
leveling observation data and creates abstracts, bok files, and VESTBOS datasets for
submission to the National Geodetic Survey (NGS). The program includes many built-in
functions such as predicting temperature differences, refaction corrections, rod
corrections and plotting. Also included are routines for editing *.lvl files and
VERTOBS files.
WinDesc NGS supported Description Entry Software. Create by Malcolm Archer-Shee while an employee of MD DOT.
LVL_DH LVL_DH Computes the expected leveled difference in height between two North American Vertical Datum of 1988 (NAVD 88) bench marks.
PC software is available for download.
VERTCON Computes the modeled difference in orthometric height between the North American Vertical Datum of 1988 (NAVD 88) and the National Geodetic Vertical Datum of 1929 (NGVD 29) for a given location specified by latitude and longitude. This conversion is sufficient for many mapping purposes.
PC software is available for download.
Gethvlst 5.01 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.
Vrec.zip Malcolm Archer-Shee's original Vrec field data recording software used on Dos based handhelds. This software was used by the MD DOT to collect data in the field for later processing in the office. Includes source and executable. Similar to NGS old VERREC field recording software used on the Corvallis MC-V handheld data collector.
