Why was the data set created?

This data set was created to provide a visual reference for the Aupuk Gas Seep.


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: 19-Jun-2006 (process 1 of 1)
    The video clip of Aupuk Gas Seep was taken on June 19, 2006 at 11:15am AST. An Olympus C-750 (4 megapixel) digital camera was used to record the video. The latitude and longitude of the film were recorded with a handheld Garmin GPSMAP 60CSx.

  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 latitude and longitude of the video clip presented in this report were collected with handheld GPS units which is accurate to approximately 20 feet.

  2. How accurate are the geographic locations?

    The horizontal position accuracy on point data is approximately 20 feet based on the error range in the handheld GPS units used to collect spatial information.

  3. How accurate are the heights or depths?

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

    When plotted on a topographic base map, the location of the data collected accurately reflect the location of the video clip.

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

    No topologic relationships are present in this data set.
