I haven't heard any similar complaints, so I wouldn't be too worried. My guess is that Google Maps does not geocode exactly the same as the Google Geocoder.

When using the Google Maps web site I get one set of Long/Lat but using GeoKit (thru Google Maps) I get a different set (slightly off by about 1/4 mile). For instance google gives: -71.119759 while Geokit gives: -71.124938 Here's my code: results = Geocoding::get(params[:searchField]) if results.status == Geocoding::GEO_SUCCESS coord = results[0].latlon RAILS_DEFAULT_LOGGER.error(coord); (email me and I'll send more details) Thanks, Gary PS. Complete RoR newbie.. So could easily be my mistake. Just starting on a site using GeoKit and I noticed an “oddity” about an address..

We are using primitive trig functions that are common to both MySQL and Postres. Nope, not using those functions. We are using primitive trig functions that are common to both MySQL and Postres.

Like I have a method in my cities model that finds by radius, and is using PostgreSQL for that.

Also I want to make sure to say: I LOVE THIS PLUGIN! So a huge thank you. Since you asked for input, the big problem for me is that eager loading (:include) doesn't work. This is already talked about here: http://jystewart.net/process/2007/03/select-and-include-in-activerecord-queries/ I'm a bit stumped how to get around the problem without going from one database query to possibly hundreds (and even then not very well). I think I might have to add duplicate lat/lng data to the model that my mappable model has_many of. However with my data I will get dupe parents, so I'll need to select distinct (if that works with GeoKit) or just filter dupes on the app layer. Kind of a bummer about the dupe lat/lng data though (DRY). Anyway, seems like a tricky problem. I'm trying to avoid monkey-patching Rails...

I quickly inspected the Will Paginate code and on the surface, it seemed like it was playing with the finder options just like we are in GeoKit. In both cases, we add options to the finder, use them, and then strip them out seamlessly. I'll have to create a test case to follow it exactly. Bill Hey There,

Currently, with will_paginate, I get an Unknown key(s): origin when doing my finds. <code> @places = Address.paginate :per_page => 10, :page => params[:page], :include => [:place], :origin => @location, :conditions =>['distance Howdy Bill,
