- Two programs for performing GEOID99 interpolation on small computers have

- DSWorld plots NGS network points by state, county and type
(vertical or horizontal) in Google Earth.
Google Earth must be installed prior to running DSWorld.
NOTE: After installing DSWorld,
please run 'Tools>Update Program' to insure you have the latest intermediate
NOTE: Because of changes to NGS web offerings, older versions of DSWorld no longer function. Please upgrade to the latest release (2.05 or better).
- Rinex Manager (RM) is a graphical interface used, amongst other things, to edit the header records of RINEX files with survey metadata, e.g. observer, antenna serial number, etc. Once the RINEX files are properly populated with survey metadata, RM can be used to automatically construct a complete Bfile for the survey. RM utilizes UNAVCO.s TEQC RINEX utility in the manipulation of RINEX files.
