Getting ready
We will be reusing and building upon data used in the Adding PostGIS layers – QGIS recipe. If you skipped over this recipe, you will want to do the following:
- Download the following ZIP file from the U.S. Census Bureau's FTP site:
ftp://ftp2.census.gov/geo/tiger/TIGER2012/EDGES/tl_2012_39035_edges.zip
The shapefile is All Lines for Cuyahoga county in Ohio, which consist of roads and streams, among other line features.
- Extract the ZIP file to your working directory and then load it into your database using shp2pgsql. Be sure to specify the spatial reference system, which is EPSG: 4269, and name the table lines.
