NOAA's National Geodetic Survey (NGS)


NOAA's National Geodetic Survey (NGS) defines and manages a national coordinate system. This network, the National Spatial Reference System (NSRS), provides the foundation for transportation and communication; mapping and charting; and a multitude of scientific and engineering applications.

Committed to making transportation and navigation safer, NGS conducts aerial photography surveys near airports in the United States and its possessions to position obstructions and aids to air travel. NGS also maps the coastal regions of the United States and provides data for navigational charts.




Product Name: DCAR97
Product Category: Image Processing/Remote Sensing - Software

DCAR97 is a companion product derived from CARIB97. The geoid is a surface of constant potential which conforms to sea level in an average sense. Deflections of the vertical are the slopes associated with the Earth's equipotential layers. The deflection of the vertical is the departure a plumb bob would take from vertical defined by an ideal ellipsoidal Earth. These quantities are typically a few arc seconds, but can reach an arc minute of departure.

Product Name: DEFLEC99
Product Category: Geo-Imaging/Data Management - Management

DEFLEC99 is a companion product derived from GEOID99 representing the deflections of the vertical at the surface of the Earth. The deflection of the vertical is the departure of a plumb bob's true pointing from the ellipsoidal normal direction. These quantities are typically a few arc seconds, but can reach an arc minute of departure.

Product Name: DMEX97
Product Category: Image Processing/Remote Sensing - Software

DMEX97 is a companion product derived from MEXICO97. The geoid is a surface of constant potential which conforms to sea level in an average sense. Deflections of the vertical are the slopes associated with the Earth's equipotential layers. The deflection of the vertical is the departure a plumb bob would take from vertical defined by an ideal ellipsoidal Earth. These quantities are typically a few arc seconds, but can reach an arc minute of departure.

Product Name: GEOID06
Product Category: Data Management - Software

For working with the GEOID06 model, two FORTRAN programs are provided as source code (INTG.FOR and XNTG.FOR) and as compiled executables for both Sun Unix (INTG and XNTG) and IBM PC (INTG.EXE and XNTG.EXE) platforms. INTG will interpolate geoid heights from data files using user-provided coordinates. XNTG will extract sub-grids from the binary data files, as well as convert back and forth between binary and ASCII, or just give statistics about a data file.
