Pennsylvania Spatial Data Access (PASDA) has USGS digital orthophotography available for download. This data is supplied by the United States Geologic Survey as DOQQs (Digital Orthophoto Quarter Quads) in geotiff and mrsid format. The imagery is broken down in a tiling structure based on the USGS 7.5 minute quadrangles and the county is covered by 29 of these USGS quads. They are as follows:

Allentown West Friedensburg Reading​
​Auburn Hamburg Sassamansville
​Bernville Kutztown Sinking Spring
Bethel ​Manatawny Strausstown
​Birdsboro Morgantown Swatara Hill
​Boyertown New Ringgold Temple
​East Greenville New Tripoli Terre Hill
​Elverson Orwigsburg Topton
Fleetwood Pine Grove ​Womelsdorf
​Fredericksburg ​Pottstown


Of these 29 quadrangles, they are further broken down into quarter quadrangles. Using this method each quadrangle is broken into a NE, NW, SE, & SW quadrant. (For example the Reading Quad has four quarter quadrangles: ReadingNE, ReadingNW, ReadingSE, ReadingSW). Therefore the county is covered by 86 different quarter quadrangles. To determine which tile you may need please reference the following map which displays the the tiling structure of the entire county.
