| |
| [ids=range] [coords=x,y[,x,y,...]] [bbox=x1,y1,x2,y2]
| |
| [polygon=x,y[,x,y,...]] [where=sql_query] [--verbose] [--quiet]

| |
|
| |
|
| Parameters:
| | == Raster digitizer == |
| map Name of input vector map
| |
| layer Layer number
| |
| A single vector map can be connected to multiple database tables. This number determines which table to use.
| |
| default: 1
| |
| type Type
| |
| Feature type(s)
| |
| options: point,line,boundary,centroid
| |
| default: point,line,boundary,centroid
| |
| tool Editing tool
| |
| options: create,add,delete,copy,move,flip,catadd,catdel,merge,
| |
| break,snap,vertexadd,vertexdel,vertexmove,select
| |
| create: Create new (empty) vector map
| |
| add: Add new feature(s) to existing vector map
| |
| delete: Delete selected feature(s) from vector map
| |
| copy: Copy selected features
| |
| move: Move selected feature(s) in vector map
| |
| flip: Flip direction of selected vector lines
| |
| catadd: Set new category(ies) to selected vector feature(s) for defined layer
| |
| catdel: Delete category(ies) from selected vector feature(s) for defined layer
| |
| merge: Merge selected vector lines
| |
| break: Break (split) vector line into two separate lines
| |
| snap: Snap one vector line to another
| |
| vertexadd: Add new vertex to selected vector lines
| |
| vertexdel: Remove vertex from selected vector lines
| |
| vertexmove: Move vertex of selected vector lines
| |
| select: Select lines and print their ID's
| |
| input ASCII file to be converted to binary vector map, if not given (or "-") reads from standard input
| |
| move Difference in x,y direction for moving feature or vertex
| |
| thresh Threshold distance
| |
| default: 0
| |
| cats Category values
| |
| Example: 1,3,7-9,13
| |
| ids ID values
| |
| Example: 1,3,7-9,13
| |
| coords List of point coordinates
| |
| bbox Bounding box for selecting features
| |
| polygon Polygon for selecting features
| |
| where WHERE conditions of SQL statement without 'where' keyword
| |
| Example: income < 1000 and inhab >= 10000
| |
| = r.digit = | |
|
| |
|
| The r.in.poly ascii format is almost the same as the standard vector ascii format. So the new digitizer should be able to output for both, and then we have a replacement for r.digit too! | | The {{cmd|r.in.poly}} ASCII format is almost the same as the standard vector ASCII format.
