To celebrate National Day of Civic Hacking, over 30 federal agencies have released new datasets and challenges to hack. They are available here:

The city of Las Vegas has an open data portal as well, with many data repositories. That data can be found here:
https://opendata.lasvegasnevada.gov/browse?limitTo=datasets
An API for crime in Las Vegas has been setup. You can access data using the following formats:
http://curs.es:9000/lat/<latitude>/lng/<longitude>/distance/<distance>
Distance is in meters and max distance is 5000 meters.
Example: http://curs.es:9000/lat/36.079411233095/lng/-115.02346661800036/distance/5000
You can also specify a time frame like so:
http://curs.es:9000/lat/<latitude>/lng/<longitude>/distance/<distance>/startDate/<start date>/endDate/<end date>
Year is in YYYY-MM-DD format.

CitySDK is designed with modularity in mind. Are you working on a project and want to include population, income, or any other Census data? Load the Census module! Would you rather tell people where the closest Farmers' Market is? There's a module for that.
