title: How do I bring raw map data to Google Maps overlay/layer?
body: <p>I wish to develop a mobile app (probably on Android) that plots disabled parking spots block by block on Google Maps. Given that the appropriate city/government agencies will most likely provide this data in some sort of paper printout of maps, how do I migrate this to a overlay/layer for Google Maps?</p>
  
  <p>Any kind of help would be greatly appreciated</p>
