   • TC_3838

3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

1. How well have the observations been checked?

   No estimate made for the accuracy of the data in the original report. Data digitized by the USGS and partners were visually compared to the source data, and corrected. Where appropriate, data were tested for completeness using MS Excel. Locations checked using GIS.

2. How accurate are the geographic locations?

   Navigational techniques not recorded in report; latitudes and longitudes given in degrees, minutes, seconds

3. How accurate are the heights or depths?

   Water depth determination technique not noted in report. Water depths given in meters from Mean Low Low Water.

4. Where are the gaps in the data? What is missing?

   All data in report are included.

5. How consistent are the relationships among the observations, including topology?

   Data fall within normal ranges for the given parameters.

How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?
