TRANSECT THROUGH POLYGON SHAPEFILE
==================================
Description
-----------
Transect for lines and polygon shapefiles The goal of this module 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 module 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].
Parameters
