USGS now has downloadable 7.5 quad maps. You need Adobe Acrobat reader and GeoPDF toolbar. The toolbar is available on the USGS site. You can plot Lat & Long, and Elev. Also you can zoom in to 400% with without changing the scale. This is usefull in ploting grade, alignment of a rail line and will enhance the use of track charts in determining milepost grade crossings. I hope you all will make use of this new tool in your modeling.
