Turbellarian Biogeographic Database


I. Tools we use for mapping collection records

When available, geographic coordinates for collecting sites are taken from publications. Typically, however, the publications provide only place names where collections were made, and we then must use other resources to map those sites out.

We take geographic coordinates from maps and charts, including the following sources. Many of these sources use the same data, but they differ in how queries work on them and in whether their maps can be enlarged for zooming in on specific locales. When all else fails, we use a published atlas or search on Google to see if the place name has a link providing coordinates. Also increasingly useful is Google Books which has made scans of older literature available (where reprints are scarce), and this can yield not only specific locality information but useful figures and scientific information on taxa and geographic sites.

II. Instructions for using maps

Maps of collecting sites can be reached from the table listing species distributions (shown when the "dist'n" links in species lists is clicked. Both maps of individual sites and of whole species distributions are available:
