LA county only have 4 government facility POI, not including business
city hall, city park, that is it !!! Basically useless !!!
City of Los angeles have average 100 new business license application every day ! Each business is a new POI.
Plus closed business, POI removed. Basically POI is very dynamically changing every day.
To get up to date POI, you must have to efficient tools to grab POI in 10 mins in a very easily manner. So you can update POI frequently, every week, let's say.
If each time you update POI took you 4 hours, you will not want to update POI per week.
If each time you took only 10 mins to update POI, you can do it every week easily !
Effecient POI grabber tool is what you need.
