Process step 3
Process description: TIF images were opened in Adobe Illustrator and lines of latitude and longitude were drawn connecting tick marks on map edges. Images with latitude and longitude lines were then exported as JPEG images.
Process software and version: Adobe Illustrator CS4, v. 14.0.0
Process date: March 2011
Who did this process
Michael H. Trippi
U.S. Geological Survey
Process step 4
Process description: JPEG images were georeferenced at points of intersection of latitude and longitude lines using ArcMap georeferencing software.
Process software and version: ArcMap v. 9.3.1, ArcInfo license
Process date: March 2011
Who did this process
Michael H. Trippi
U.S. Geological Survey
Process step 5
Process description: Georeferenced JPEG images were added to ArcMap project and polygon features representing coal-bearing formations were created and added to the BangladeshCoalfields shapefile.
Process software and version: ArcMap v. 9.3.1, ArcInfo license
Process date: March 2011
Who did this process
Michael H. Trippi

Process step 6
Process description: Polygon features were assigned values for ID, Coalfield, DataSource in the shapefile's attribute table. Unique ID values were assigned to each feature.
