Store Locator

Ascsoftw Store Locator is a powerful plugin which lets your users Search the Nearest Stores and display them in highly customized Google Maps.

This plugin is extremely simple, and intended for someone who wants to add geocoding to their blog, but without the bloat of a big fat plugin. This lets you tag each post with a location (description, latitude, longitude) which can then be used in your custom theme.
This plugin also provides a feature to track of a single location not associated with any posts. This is useful in order to create a “Where Am I?” feature on your blog where you control the level of detail (just to share the city, rather than pluggin in foursquare data). This is especially nice if you’re running a travel blog or a website for some kind of tour.

EasyGeo

Adds simplest geocoding features to WP posts (description, lat, long). Adds nothing to the front-end, but has tools for you to do so in your themes.
