After having been used PostgreSQL for some years, I just learn the PostGID lately. Currently, I need to solve a street address and distance problem which is to find out the distance between to given street address (or well know location as such the city hall in a city) or to find out whether a street address is inside of a given distance from another street address. I am wondering whether PostGIS can help me to solve the problem or not. I understand I first need to convert a street address into a pair of latitude and Longitude.
