BINS
Temporary storage for species of unknown taxonomy.
COLLECTION
A subset of the database records that have similar properties (such as data that has been quality controlled). See Collections for more info.
Data Driven Pages
An index layer is used to produce multiple output pages using a single layout. Each page shows the data at a different extent. The extents are defined by the features in the index layers.
