Description:
Abstract:
Please see: ogq_general_metadata.doc for detailed information on this dataset. This text file will be included in the zip file.
 
The original data set consists of six shapefiles pertaining to energy development and production in Colorado. The set includes one shapefile for each of the following categories: communitization agreements, gas storage agreements, geophysical permits, geothermal leases, oil and gas leases, and oil and gas units. These shapefiles are generated based on tabular data drawn from BLM's LR2000 database using BLM's geospatial GCDB database as a geographic reference. The GCDB database contains continually updated cadastral information collected by BLM's staff surveyors.
Purpose:
These shapefiles are generated on a quarterly schedule to provide the public with updated graphical and attribute information regarding the energy categories listed above.

Lineage:
Process_Step:
Process_Description:
For each shapefile, a list of appropriate case types is fed into a Python script that executes an SQL query against BLM's LR2000 database to extract all authorized and pending case records for those case types. These records contain case attributes as well as legal land descriptions for each parcel of land involved in the individual cases.
Process_Step:
Process_Description:
Each set of extracted LR2000 records is then fed into a second Python script that creates shapefiles by matching LR2000 land descriptions against features in the GCDB database. When a direct match is found, the corresponding polygon in GCDB is used as a template to create a new feature in the output shapefile. If no direct match is found in GCDB, the script will attempt to create a polygon by subdividing a larger feature it could find in GCDB. If this also fails, a note is made to a log file listing all such failures.
Process_Step:
Process_Description:
Each of the shapefiles generated in previous step is checked for geometry errors and repaired if necessary. The shapefiles are then dissolved on case-level attributes and projected to the NAD83/UTM13N coordinate system. A comma-delimited error file is generated for each shapefile that had errors, and an MS Word document is prepared to briefly describe the data set as a whole. The final package consists of the shapefiles, the error files and the Word document. The error files can easily be viewed and analysed in MS Excel.
