Using Google's My Maps is the easiest way to do this.Some favorite restaurants in Richmond, VAHere's a super quick map we put together to show some favorite restaurants in Richmond, VA.

All the information you need to do this for your site is available at Google's My Maps.Markers pulled from databaseOur dynamic map for Public Service Jobs Directory (PSJD) is a great example of what you can do with Google maps using data from a database. PSJD is a job search site for people in the law profession who'd like to work in public service.

Layers in the map allow users to filter results.Maps using geospatial dataOne step further is a map type that uses geospatial data to populate the markers.

Think about your data and how you want your users to use it.How will it look and behave?Each marker is a point location on the map; not only is the location displayed but you can also add and format text, embed a photo or video, and link to more information. Again, think about what you want here and what you want your users to do.Where will you get the data?Determine where you can get other data, whether from your own database or through geospatial data offered by third-party providers. For example, for our DC-area map examples, we used the map tiles and geocoding service from Cloudmade.com.Learn moreThere are quite a few blogs and sites devoted to mapping, from the map collection at the Library of Congress to Google's mapping blog.
