Why was the data set created?

The Division of Forestry has been selling timber for many years in the Fairbanks area. The purpose of this map, is to compile all the timber sales in one data set to allow querying of data through time. It allows state resource managers the ability to track timber sales across the landscape to aid in forest management. It provides the public with documentation of timber sales on state land and a basis to comment on future sales.


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: Oct-2006 (process 1 of 2)
    Timber sale attributes were researched from individual timber sale files. Timber sale boundaries digitized from paper contract files were re-positioned to align to timber sale cut boundaries that appear on SPOT satellite imagery.

    Date: 30-Jun-2008 (process 2 of 2)
    Metadata updated by Ken Papp (Metadata Manager, Alaska Energy Data Inventory Project Manager, Alaska Division of Geological & Geophysical Surveys). Significant additions were made to the "Entity_and_Attribute_Information" to provide better descriptions of attributes and enumerated values. Metadata was also validated by the USGS Metadata Parser, mp.

  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?

    Location of timber sales was determined by digitizing old contract paper maps. Newer timber sale boundaries are created from GPS ground data.

  2. How accurate are the geographic locations?

  3. How accurate are the heights or depths?

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

    Small negotiated timber sales do not appear in the data set.

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

    Polygon topology present and clean on appropriate data.


How can someone get a copy of the data set?

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