Hi Stéphane, For US locations, you might try www.nationalatlas.gov, click on MapMaker (upper left) and then 'Find' (upper right). It allows you to search by name of geographic features. I've found some small ponds by name and state using this.

I have a paper, where there are some data that I would like to analyse with spatial tools. In the appendix of the paper, for each site, there are some data... but I do not have the spatial coordinates of sites, I have only the name of the site, e.g. : Blue Lake, WA 4. I would like to obtain coordinates (latitude and longitude) for these sites. All the sites are in USA and Canada. I have two questions : - what means the number in the address ? eg. what "4" means in Blue Lake, WA 4 ? - Do you know some sites/free tools that can be used to obtain the spatial coordinates ?
