I need to show on a web map some points (> 12.000) ... I know that there are many solution for that, also for free (CartoDB, MapBox, ArcGIS On Line, ecc ... ), starting form some shapefiles. That is not my problem
My problem is the follow: I've a table with this structure
TABLE_1: key, x-coord, y-coord, attr-1, attr-2 .....attr-n
and another table with this structure
TABLE_2: key, description
Selecting a value for KEY in TABLE_2 there are several rows in TABLE_1 for that KEY value (1:n relationship).
I'd like to select a value in TABLE_2 and show (or better, point out ...) the points of related rows in TABLE_1 on my map.
I'd like to find a solution without writing "ad hoc" code because my customer is really entry level on GIS or web mapping and I've to keep as more simple as possible my solution.
Any suggestion or example about a situation like this one?
Thank you very much in advance
