Each yearly section, will be processed a half year at a time using roughly four steps:
For each year I make sure the bottom axis (bottom left - bottom middle or bottom middle - bottom right) is aligned along the Cartesian x-axis. This is done by rotating the data around the bottom left or bottom middle point, respectively. -> in this image the axis is relatively close to optimal!
Since I only process data within half a yearly section I trim annotated lines to fit each six month period.
After trimming the annotations to fit neatly within the first six months I need to transform all these coordinates to days within a year. I know the spacing between the row is equal. As such, the total length of a row can be calculated as the distance of a line which crosses the beginning and end of half a yearly section.
What remains is to calculate the distance between the beginning and start of an annotated segment relative to the total length to determine the days they cover during the year.
Finally, all these data will be combined into a matrix. This matrix will then be linked to the original species data, kept in a separate file.
