1. Abstract
The coverage represents the geographic locations of rain stations
in Chad.
Descriptors: Chad, Africa, Rain Stations
2. Applications that use this data
Modeling, targeting, and demonstration projects.
2.1 Intended use of data
Used to spatially depict rain station locations.
2.2 Limitations of data
This coverage should not be used for navigation or for producing
maps needing high geodetic accuracy.
3. Attribute discussion
(STATNOM) Is the item that defines the rain station name.
(AGRH) Is the item that defines the AGRHYMET ID.
(ID) Is the item that defines the RAINMAN internal ID.
(LATITUDE) Is the latitude of the rain station.
(LONGITUDE) Is the longitude of the rain station.
(ALTITUDE) Is the altitude of the rain station.
