Gravity Data For Colombia 1997

Dataset Identification:

Resource Abstract:
The gravity station data (9,050 records), were observed and processed by the Instituto Geografico Agustin Codazzi(IGAC), in Colombia from 1958 to 1996. This data base was received in April, 1997. Principal gravity parameters include Free-air anomalies and both Simple and Complete Bouguer anomalies. The gravity anomaly values were computed using the GRS80 ellipsoid.

evaluation Method Description  Horizontal accuracy varies from source contributor to source contributor. However, horizontal positions are usually taken from topographic maps of the area being surveyed. Accuracy may range up to +/- 100 feet.
AbsoluteExternalPositionalAccuracy
name Of Measure Vertical Positional Accuracy Report
evaluation Method Description  Vertical accuracy varies from source contributor to source contributor. However, vertical positions are usually taken from topographic maps of the area being surveyed, monumented benchmark locations, or they are determined by the use of the Global Positioning System (GPS). Accuracy may range from meters to centimeters or better.

evaluation Method Description  Gravity data values are the result of the measurement of small variations in the gravitational field of the earth. The magnitudes and ranges of these variations are well known in the potential field discipline.
Quantitative Result
result value Variable: the average acceleration on the Earth's surface is about 980 centimeters per second squared, which is equal to 980 gals, but increases by about 1/2 percent from equator to pole.
