I'm hoping someone can give me some advice about how to handle a dataset I've discovered for a project I am working on.
There is a group out of the University of Nebraska working on digitizing historic railroad maps, and they've made this data available to the public here: http://auroraproject.unl.edu/web/data/rail.xhtml
After downloading, I found the data is in .sql format. I'm pretty comfortable with ArcMap, but have no familiarity with PostGIS or any similar programs.
Can someone give me some advice about how to get this data into ArcMap? Thanks so much in advance.
