Other Stuff

Houston Crime Watch Houston police department crime data being mapped on to google maps, for two localities close to downtown. Geocoding uses the Google geocoding API to convert street addresses to Map points. The accuracy of the map relies on both of these services coming soon!color coded markers, for easy identification for high risk areas

Code Snippets and Utilities Some code snippets and utilities, that I have picked up, as part of work.
