Tilia is an MS-DOS program designed to record and display - in conjunction with Tilia·Graph - stratigraphic data. Tilia and Tilia·Graph are particularly designed for pollen data, but can be used for a wide variety of stratigraphic, geologic, and ecological data.
With Tilia you enter your sample and variable information and then fill in the spreadsheet with your data. Tilia includes forms for recording metadata such as site information (site name, latitude, longitude, etc.), radiocarbon dates, publications, and chronologies. You can calculate sample ages based on the chronology information you entered in the forms.
Tilia·Graph plots pollen or other stratigraphic data. You have a high degree of control over the diagram format: graphs may be plotted as silhouette curves, hisograms, presence/absence, or raw numbers. Curves can be filled with a variety of patterns. Depth bars and exaggerated curves can also be plotted.You can create cumulative or overlaid graphs.You can scale both horizontal and vertical axes; define major, minor, and labeled tic marks; and enter axis labels. You can optionally plot by age or by depth. Graph names can be plotted at any angle from 0 to 90 degrees, in one of several fonts.
Tilia and Tilia·Graph were developed by Dr. Eric Grimm at the Illinois State Museum (firstname.lastname@example.org). Tilia is available free of charge; Tilia·Graph costs US$250.
The versions of Tilia and Tila·Graph described here are 2.b.0.5. The distributed package includes a third program, CONISS, which carries out Constrained Incremental Sums of Squares analysis on a Tilia file.
