Tilia is software designed for managing and graphing paleontological data and metadata, especially stratigraphic data. The program is especially suitable for graphing microfossil data such as pollen, ostracodes, and diatoms, although it may be used for graphing virtually any kind of stratigraphic data.
Tilia runs on the Microsoft® Windows® platform, version XP or later, either 32-bit or 64-bit. Many users run Tilia on the Apple® Macintosh® under Parallels®or the Open Source VirtualBox. 

  • Spreadsheet for entering data, samples and variables (e.g. pollen taxa, loss-on-ignition, geochemical variables, charcoal).
  • Download data directly from the Neotoma Paleoecology Database.
  • Automated calculation of sums for calculation of percentages.
  • CONISS cluster analysis, both stratigraphically constrained and unconstrained.
  • Forms for entering metadata for site, collection unit (core, excavation). dataset, geochronologic data (e.g. radiocarbon dates), and age-model data, contacts, and publications.
  • Google Maps interface for acquiring site latitude-longitude coordinates.
  • Automated generation of simple age models using linear interpolation, polynomial interpolation, splines, and more.
  • Export of input files for other age modeling software (clam and Bacon) and import of sample ages produced by these programs.
