Rozeta

Rozeta is a program that plots rose diagrams.

A rose diagram is a circular histogram that shows the distribution of linear elements on a plane. It can be, for example, the distribution of transport directions in a sedimentation basin, inclinations of fracture planes, paleocurrent directions, wind directions, etc.

Rose diagrams are often used in structural geology, geography and other sciences.

I wrote the first version of the program in 2001, when I was studying geology.
When I was once again given the task of drawing a rose diagram, I decided to write a program for drawing such diagrams based on the measurements stored in a text file. To write the program I used the Borland Delphi 5 development environment. I never made the program available (I didn’t even have a permanent internet connection at the time). The program was used only by a small group of my friends who used it, among others, when writing their master’s theses.

I released the second version in 2003 (Polish version) and 2004 (English).
The program already had a bit more options and was available on my website. Unfortunately, it contained a few bugs that made it almost impossible to use in newer versions of Windows, so after a few years I removed it from my site.

While browsing the source codes of my old programs, I came across the Rozeta and decided to write another version, the 3rd.
Initially, I wanted to expand version 2.0, but I wanted the program to be open source and use only free development tools, so I wrote Rozeta completely from scratch in the Lazarus environment.

Why did I name the program Rozeta?
Rozeta is a common name for a rose diagram used by geology students in Poland (at least 21 years ago).
