I showed this last week, but the app crashed and burned after about an hour. I'm pretty sure I figured out the issue(s) and fixed them, but I'll be interested to find out if that's really the case.

Hi, looks interesting. How well organized were the city/county records? Did you have to do a lot of parsing and extractions from documents? Or, was the data well organized in databases or csv files?

The data was sourced by using ogr2ogr to grab the data from an arcGIS server that the city runs and convert it to geojson. There was also an associated Sales db that I was able to query all results for, so I grabbed those and stuck them in MongoDB for the purpose of linking the parcel data with the property number in the db. When a user clicks on a property, I search mongo for the associated records and update the html via socket.io.

thanks - is this a demo project or are you thinking of doing this as a business service available across other locations?

I mostly built it as an exercise in curiosity, but I'm certainly open to letting the universe decide what's next...

I recently was showing an acquaintance of mine a demo of something I was playing around with and a potential business model. He responded with "I wouldn't be that interested but if you could use those same capabilities to deliver X, now that is something I would pay for."

When I went and looked at your demo I thought here could be someone who is already walking down the road toward being able to deliver a critical component of X.

If you want more details lets switch over to email. You can find one of my contact emails in my HN profile.
