Building a Routing or Road Network from a Road Layer

Do you know where this is?

I route school buses using GIS for a school district in Utah. Over the last year I have been using public road data as a source for our routing network. The process of converting the road layer to a routing network took a couple weeks but has saved us from buying the data privately. Public data isn't perfect and I have had to fix numerous errors but I have sent those fixes to the source (AGRC) which will build a more accurate dataset for everyone. I wrote step by step instructions on how to create a routing or road network from AGRC road centerline data and it was recently published on a blog post on their website. If you have any questions please let me know!

Lidar Salt Lake City

Introducing downtown Salt Lake City through the eyes of Lidar. This map

was made from public Lidar data from the AGRC. It is based off of a DSM 

(Digital Surface Model) that has been processed with a hillshade. It reminds 

me of a classic plat map or some of those city word art maps. Salt Lake's

unique geography really helps bring out this feeling. This will hopefully be

the first of many as I delve into other cities datasets and try to make similar ones. 

Please let me know if there are any cities in particular that you would like me to look 

at first. Also, if you are interested in a nice print version just send me a message or 

leave a comment below.
