Description
Transect for lines and polygon shapefiles
The goal of this tool is to create a transect along a line through a polygon map.
Eg
|____ST1_____!_ST2_!__ST1__!_______ST#_____|
(Soil type 1 etc...)
This is done by creating a table with the ID of each line, the distance
to the starting point and the different transects:
| line_id | start | end | code/field |
| 0 | 0 | 124 | ST1 |
| 0 | 124 | 300 | ST2 |
| 0 | 300 | 1223 | ST1 |
| 0 | 1223 | 2504 | ST3 |
| 1 | 0 | 200 | ST4 |
| ... | ... | ... | ... |
The tool requires an input shape with all the line transects [Transect_Line]
and a polygon theme [Theme]. You also have to select which field you want to have in
the resulting table [Transect_Result]. This can be an ID of the polygon theme if you
want to link the tables later on, or any other field [Theme_Field].
