| DMA Reference Base Station Network Data |
| The data (15,904 records documenting 9,090 worldwide gravity base stations) were gathered
by various governmental organizations (and academia) using a variety of methods. This
data base was received in August 1993. Principal gravity parameters include station
id and observed gravity. The observed gravity values are referenced to the International
Gravity Standardization Net 1971 (IGSN 71) and the gravity anomalies are computed
using the World Geodetic System 1984 (WGS 84) theoretical gravity formula. The spatial
resolution of the data is randomly distributed throughout the world. Note that the
dmanet93.bin file contains only the station name for each of the 9,090 stations. The
complete listing for each station(including any supplementary records), are contained
in the ASCII file named dmanet93.asc. |
