Why was the data set created?

This data is created for display purpose for online mapping application for Parks (ParkFinder). The data is simplified for the purpose of the application.

How was the data set created?

  1. From what previous works were the data drawn?

    (source 1 of 1)
    Type_of_Source_Media: None
    Source_Contribution: trail_line data in plibrary

  2. How were the data generated, processed, and modified?

    (process 1 of 1)
    This is currently manual process. 1) Export plibrary trail_line to file geodatabase \\dnrp1\project\Parks\working\projects\ParkFinder\data\parkfinder.gdb\pf_regionaltrail_base. 2) Delete and add fields in pf_regionaltrail_base. Delete segment of trails if necessary. 3) Export pf_regionaltrail_base table and convert to excel (pf_regionaltrail_length.xls). Create pivot table to calculate surface type and distance in feet and save. Export pivot table to file geodatabase as trail_length. 4) Dissolve pf_regionaltrail_base FC on alial_name, save file as pf_regionaltrail_simple. 5) Join pf_regionaltrail_simple and trail_length table, export FC as pf_regional_trail_general_display. 6) Export to maint.

  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?

    Trail name may be different from original trail data due to the public display and ease of the online mapping application requirement.

  2. How accurate are the geographic locations?

    Some section of the trail data may be mission due to the client request.

  3. How accurate are the heights or depths?

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

    This dataset is completed as of 5/25/2010 based on trail_line feature class in plibrary. All regional trail information were reviewed by Robert Foxworthy, Gavin Gran and Yuko Caras for web mapping line representation only.

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

    This feature class is created for online mapping purpose and do not carry detailed information. There is at least one segment of onstreet section is dropped from original trail_line data and some trails were combined or given new names.

How can someone get a copy of the data set?

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