I was told to implement a web service which, given 2 inputs (street name, cross street name) the output is the crossing geographical coordinates.
What is the best way i should go? Is there a standard for Geographical Web Services that queries a database? Are there same similar examples? (I haven't found anyone)
We use PHP, and a Postgres database with Postgis.
I have developed a solution whith nusoap and xml but I really don't know if this is a good solution.
