making queries

[Stephen Lime]

These types of buffer queries are not supported at the moment. You could accomplish
this using MapScript however. For example you could:

1) select all with beer sales permits
2) calculate distance from company to railway

MapScript has several distance computation (simple euclidan) methods available for
point and shape objects. There may be even other ways to accomplish this but I'll have
to think about it a bit more.

Hi dear mapserver users,


Does anyone have experience in selecting features by making a query command?
Is this possible?

For example:

I like to select all companies which are within 200 meters from the railway
station and have a permit to sell beer.

Is this possible with mapserver?   

Best regards,
Herman de Haan
