Get all SAFRAN gris ID info from shapefile

Source: R/TNETutils_getSAFRAN_fromShape.R
TNETutils_getSAFRAN_fromShape.Rd

Get all info of SAFRAN grid where all river segments are located from the T-NET readable format to a better R understanding format.

Usage

TNETutils_getSAFRAN_fromShape(shapefile)

Arguments

shapefile

Path to the shapefile with all info on segments. It must contain the following columns:

\(gid\_new\)ID of the Topage segment
\(ID\_M\_1\)ID of the SAFRAN grid n°1 where the segment is located
\(ID\_M\_2\)ID of the SAFRAN grid n°2 where the segment is located
\(ID\_M\_3\)ID of the SAFRAN grid n°3 where the segment is located
\(ID\_M\_4\)ID of the SAFRAN grid n°4 where the segment is located
\(ID\_M\_5\)ID of the SAFRAN grid n°5 where the segment is located
\(ID\_M\_6\)ID of the SAFRAN grid n°6 where the segment is located
\(ID\_M\_7\)ID of the SAFRAN grid n°7 where the segment is located
\(ID\_M\_8\)ID of the SAFRAN grid n°8 where the segment is located
\(Rap\_M\_1\)Part of the segment located in SAFRAN grid n°1
\(Rap\_M\_2\)Part of the segment located in SAFRAN grid n°2
\(Rap\_M\_3\)Part of the segment located in SAFRAN grid n°3
\(Rap\_M\_4\)Part of the segment located in SAFRAN grid n°4
\(Rap\_M\_5\)Part of the segment located in SAFRAN grid n°5
\(Rap\_M\_6\)Part of the segment located in SAFRAN grid n°6
\(Rap\_M\_7\)Part of the segment located in SAFRAN grid n°7
\(Rap\_M\_8\)Part of the segment located in SAFRAN grid n°8

Value

data.table with for each segment, all SAFRAN grid traversed and the part of it in it.
