Format Data into JSON

[mjcarroll]

This is the data format for ChattCrimes. There was some discussion to see if we need an actual DB backend, or if the flatfile is more than enough.

I think for a hack, the flat file is fine, but I think that the DB part would be kind of nice for the longer-ish term.

if we want to use heat maps available already, it may be easy with JSON or some other DB. Will look into it more.

I think for now we could use Spatialite, which is pretty easy and standalone (Based on SQLite).

We could definite move to something like PostGIS (PostGRES + GIS).

GIS extensions allow easier querying by geographic information.

I got the heatmap working using simple HTML5, Java Script, JQuery and Google heat map API. This is done all at the client end. This is not the most sophisticated way of a doing, but you can see heat map. I have uploaded the html file. if you want to see the map, just download html file and latest .csv file. after loading html in browser, you need to load csv file using browse button, then press update Map Data button. You should see the heatmap, you may have to press "changeMaxIntensity" button to see redspots.

Next I will work on filtering the data based on "Year", "Shift", and "Incident Type" At a later time, we can think of using server pages. Currently this is all done at client machine side, no web server is required for now.
