About the Program
Funded through a grant from the Pennsylvania Department of Environmental Protection
Purpose: to create a digital archive of abandoned coal mining maps to be open to the public
Working in collaboration with 9 major colleges and universities
Maps come from the Wilkes-Barre and Pottsville DEP offices
Online Map Inventorywww.paminemaps.psu.edu
Equipment and Programs
Scanning Colortrac Smart LF Scanners
42 inch 56 inch
Smartworks Pro Scale of 400 DPI
Geo-referencing and Digitizing ArcMap version 10.2.1 ESRI PASDA (Pennsylvania Spatial Data Access)
Surface image layer
PHUMMIS Pennsylvania Historic Underground Mine
Map Inventory System Catalog all maps that are scanned,
geo-referenced, and digitized
Scanning Steps
Initial Scan Check for Errors Rotate
Look for a north arrow If no north arrow is present, follow alignment
of text Deskew Mirror (if necessary) Look for Title
Map Title
Titles are where we find the information on the map Colliery Coal Company Coal Vein Name Coal Field County, Municipality,
Quadrangle Scale Map Date
Geo-referencing Steps
Bring desired file into ArcMap Find a point on the map that can be
matched up with a point on the PASDA surface image layer Create first “control point”
Continue until 4 control points have been set
Check residuals
Finding Control Points
Useful control points Street crossings Buildings Bridges Grid System
Use ESRI to find general location
Use PASDA to match control points
Grid System
Created a grid layer in GIS as a Reference Guide
Grid systems based on company or colliery?
Digitizing Steps
Mark shafts, drifts, and slopes Only if they reach the surface
Draw a polygon around the underground mining area Cut out large areas that are not mined
(doughnuts) Mark coal elevation points
3-D Representation
