Hi again Robert,
Thanks, that was just what I was looking for! I've used Page Query to successfully filter the bird survey data, and show only the species that matches the name of the page.
Two issues I'm having now - one is that the resulting map series is showing a page for every row in my dataset, rather than a page for every species, so for each species I have an identical map for each observation of that species in the dataset.
Also, the extent is moving around slightly with each page, although the scale is staying the same.
Here's my workflow:
1. Set the Page Query for my Index Layer
2. Define my Index Layer in the Map Series tab, using the field I based the Page Query on as the Name Field and Sort Field
3. Selected Center and Maintain Scale on the Map Extent menu, using the Scale that was already in place from the Layout.
The extent is slightly shifting for each page, and I can't figure out how the extent is defined on each page. For example, two adjacent pages below:
This means that none of the templates have quite the right extent, as I had lined this up on the original template, and each page is shifted slightly.
Any ideas on why the extent is shifting, or how to just have one page for each species, rather than for every row in the dataset?
Thanks for your help!
