I have spent the last few weeks trying to build a geocoder and I am hugely underwhelmed by the solutions provided by esri. The fact that such basic functionality such as geocoding to unit level is not available in the core product is quite frankly ridiculous. The white paper "Customizing Locators in ArcGIS 10" is such a badly written document that seems to purposefully make things difficult. Trawling through forum posts to find locator styles that might work is not a good use of anyone's time. This needs to be fixed. As I have seen mentioned elsewhere, esri want people to use their online geocoding service (SaaS) so intentionally make it difficult for users to build custom locators. Also the sporadic nature of replies in the geocoding forum from esri staff is quite baffling, they may answer a question that is unrelated to geocoding, but when it comes to answers that are in the correct forum they are absent. What are peoples thoughts?
