Why is onActivityResult() Intent data equal null?

Where can I find publicly available (preferably free) businesses/places/landmark data sets to download?

  • I understand that companies like SimpleGeo provide APIs to databases with this information, but my intent is to create proprietary data sets on top of common public information like businesses, places and landmarks within a city coupled along with entirely unique information. So, assuming all intensive data mining required, I'm willing to manually put together the database in an effort to create an entirely new data set and bring that to market. Any Ideas or sources on how to do this is greatly appreciated. Thanks in advance!

  • Answer:

    We have found the OSM:http://www.openstreetmap.org/ is a good data set for landmarks and long standing businesses.  One of the issues with OSM is frequency of update.  API's like SimpleGeo are good because they insure continuous update and they eliminate the work related to setting up a geospatial database like PostGIS: http://postgis.refractions.net/.  We have combined a number of different data sources to create an aggregate place service.  Another factor is performance.  We use a Hadoop data pipeline for our system and needed a hybrid solution to support the Hadoop speed geospatial computations. If you do pursue developing your own solution the PostGIS tutorials are a great place to start: http://www.bostongis.com/?content_name=postgis_tut01
