Find Points near Linestring

[Karsten Violka]

Hi,

I want to build a table with linestrings (saved routes) and would like to

-- find all linestrings near a defined point
-- find all points (pois in another table) near a selected linestring.

I think I have to build a buffer for linestring and use it for a search.

here ist a similar solution for MS SQL-Server: http://johanneskebeck.spaces.live.com/blog/cns!42E1F70205EC8A96!4504.entry

Is there a practical solution for MySQL that also gives good performance for a large database?

thanks & best regards,

Karsten
