Configure a database for OpenStreetMap on another disk

Perhaps you need more space for your OpenStreetMap database and decide to move it to your shiny new big disk or RAID array? Sound good? Here we go. We need to create a tablespace for the database, then use it.

Create a directory for the database
sudo mkdir /raid/newgis
sudo chown postgres:postgres /raid/newgis

As the postgres user
sudo -u postgres -i

golf course rendering on Open.MapQuest.com

I like the cartography on http://open.MapQuest.com . The style differs from our mapnik and osmarender styles by rendering fewer types of objects and by using subtler colors. It's different. Their selectable thematic layers are great and let you add objects to the map that interest you at the moment. That's all pretty cool and that's not what I started this article to talk about.

I want to talk about golf.

What's in a name?

unclear sign over a dental office

A question came up on one of the OSM mailing lists1 about what to use as the name of a business. The name of a business is one of the key items that distinguishes that business from their competitors, along with location. Both of these things are important to mappers. We like to get location correct; that's kind of the point of OpenStreetMap. And once we have the location of an object, we generally want to name it.

So why are some businesses so hard to name? And what is a mapper to do about it? Let's have a look.
