When referencing the following examples be sure to replace your_partner_id with the unique partner id you've been assigned. To sign-up and receive your Partner ID go to our sign-up form.

You can use any text, graphic, or image that you choose to link to our sites. Our Banners page contains some ready-to-use graphics for you to choose from. Here's how a link might look in your HTML document when using one of our graphics:

The latitude parameter should be a positive number, and the longitude may be positive or negative (all longitudes default to the Western hemisphere) in decimal-degree format.

3. Search Links (MyTopo)

Customers can search the database for almost any feature depicted on USGS topographic maps. You can put a gateway to this powerful search engine right on your site with a simple search form.
