The program POLWIND extracts polygons out of an overall area. Only points with coordinates between certain limits of a rectangular window get extracted. Furthermore the user can choose between two output formats. For polygons in files of type insel.dat he can add a comment e.g. the date of generation. This information is not processed by other programs but it may help the reader of the file. &lt;br /&gt;
|inputfiles=&lt;br /&gt;
# file with window coordinates&lt;br /&gt;
# file with polygons of the overall area (filetype : [[DIGI.GKK|digi.gkk]])  &lt;br /&gt;
|outputfiles=&lt;br /&gt;
# (optional) file with extracted polygons (filetype: [[DIGI.GKK|digi.gkk]])&lt;br /&gt;
# (optional) file with extracted polygons (filetype: [[INSEL.DAT|insel.dat]]) &lt;br /&gt;
|methodology=&lt;br /&gt;
Polygons with one part inside and one part outside the concerning area get cut. POLWIND creates a new starting or ending point which is placed directly at the edge of the extracted area.&lt;br /&gt;
POLWIND does not extract single points. &lt;br /&gt;
