Point features present.
The error inherent from the latitude and longitude is at least 32 meters on the x-y. Errors derived from the quality of the original map or found during the automation process also can affect the accuracy of this data. The maximum error is estimated at 35 meters on the x-y. Latitude and longitude values for the monitoring sites were recorded, in the field, using GPS in May 1998. Point topology was built.
