NJ transport paths

I've started playing with geospatial data published by NJGIN.   My interests are mainly around demographics, wealth and tax distribution, and the relationships between demographics an geospatial features like terrain, proximity to transit networks, and so on. 

This map shows roads, train lines, and high tension power lines for New Jersey. The powerline data cam from HLFID.  Roads are shown down to the county level.  The map was produced with GRASS GIS.

 More maps to follow.  This first one's resolution is not so good, but I'll follow up with higher quality images in future maps.
