Where can I find some address locator styles for European countries? or how can I create my own address locator that contains street, house number and city, and use their aliases?
PS. I have the book: Customizing Locators in ArcGIS 10
Unfortunately, unless you find someone other than Esri that is willing to share locator styles with you, you are out of luck. We have being building our own locators for Canadian style addresses, and even with enterprise developer support from Esri, it has not been easy. The documentation is non-existent beyond the whitepaper, which is little help with actual customization. We've had a few questions answered, but allowing customized locators is not really the direction that are headed in, despite the ability to do so. They are also unwilling to share their locators styles (beyond the US ones), since this is a paid product that they offer (i.e. they don't want to give away details of their profit making locators).
