    1. How are geographic features stored in the data set?
      Indirect_Spatial_Reference:
      Navigation Data for Offshore Samples was provided in digital form and exported to GIS/Arc Info to make maps which include Navigation lines, Sample Sites and Sediment Thickness maps. The Waikiki and Kailua maps also include digital photo images which were registered and rectified to existing coastline data using GIS/Arc Info. Digital beach survey data provided by the Hawaii Coastal Erosion Study: Open-file Report 01-308 Hawaii Beach Monitoring Program: Beach Profile Data.
    2. What coordinate system is used to represent geographic features?
      Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.000001. Longitudes are given to the nearest 0.000001. Latitude and longitude values are specified in Decimal degrees.

Why was the data set created?

This data set is intended for scientific research of beach and offshore sand deposits composition and volume changes.

How was the data set created?

  1. From what previous works were the data drawn?
  2. How were the data generated, processed, and modified?
    Date: 2001 (process 1 of 1)
    Methods of sample preparation and procedures are discussed within the report. See Table of Contents/Methods.
  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?
    The data have been thoroughly analyzed for gross inaccuracies. A few beach samples were taken on the beach between the edge of the beach and the toe of the beach, these samples were not annotated with a point number and were assigned a point number later. The actual location of these points may vary by several meters one way or the other along the line.
  2. How accurate are the geographic locations?
    +/- ~5 m
  3. How accurate are the heights or depths?
    +/- ~1 m
  4. Where are the gaps in the data? What is missing?
    Complete
  5. How consistent are the relationships among the observations, including topology?
    Grainsize analysis was done using methods from Carver (Carver, Robert E., Procedures in Sedimentary Petrology, 1971).Composition Analyses were done using a binocular microscope. Up to 500 grains per sample over -.5 phi in size were identified and counted. A few samples did not have enough viable grains (large enough) for analysis and were not counted. In the GIS section, a few beach locations did not have any location information and were left out of this section.
