[R-sig-Geo] SpatialLines to SpatialPolygons convertion

[Henk Sierdsema]

Hi Hans,

Please have a look at paragraph 2.6 (page 41) on spatial polygons in the ASDAR-book. Here you will find an example of converting a shoreline into polygons.

Onderwerp: [R-sig-Geo] SpatialLines to SpatialPolygons convertion


Hi,

I have a short question.
Is there any workaround available which tries to convert a list of  
SpatialLines to a list of SpatialPolygons objects?

In my case I have a list of Lines objects coming from a gshhs  
(shorelines) file. The list represents 8 polygons of a given xlim/ 
ylim. Now I'd like to convert the list into 8 polygons in order to  
draw them filled out.

I could do it 'manually' and try close these lines heuristically but  
maybe there's already such a workaround available.

Thanks for any hint in advance!

PS The new maptools release is really nice :) Thanks!
