Category: Miscellaneous Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Andrei_n (andrei-n1) Assigned to: Nobody/Anonymous (nobody) >Summary: Create a single polygon from multiple contiguous areas Initial Comment: A new function for the "Create polygon from closed area". If holding the "Shift" key (for example) and clicking over multiple closed areas, the result would be a single polygon merging all the closed areas you selected. ---------------------------------------------------------------------- Comment By: Andrei_n (andrei-n1) Date: 2012-05-14 08:04 Message: Michael is right. I want to fill multiple contiguous closed areas with a single polygon. If you wonder where this function would be useful, I have attached a screen capture to this report. There I have a polygon area with the administrative limits of several (Transylvanian) counties in 1925 (green). I need to update those counties to their 1937 limits and I have used linestrings to mark the detached parts. Now I want a new polygon layer (purple) to contain the 1937 counties. Of course I can create several polygons from the closed areas, then merge them using right click->merge selected features, but this path is more time consuming. ---------------------------------------------------------------------- Comment By: michael michaud (michaudm) Date: 2012-05-13 23:17 Message: Stefan, "Create polygon from closed area" creates a single polygon from a set of noded linestrings. As I understand, Andrei would like to fill several contiguous areas to build one single polygon. Merging polygons after is also possible, but this is a second action (not as efficient as what Andrei asks for what he wants). By the way, do you know that I added a "merge polygons" in the context menu which can merge several polygons (of course, some attribute values are lost if features have different values) ---------------------------------------------------------------------- Comment By: mentaer (mentaer) Date: 2012-05-13 16:05 Message: Hei Andrei, I do not understand your wish. Can you deliver an image? As a note: merging polygon with space in-between isn't an easy thing.. and there probably several solutions possible. However, if there is no space - you would use the "Merge Two Polygons" function from the Tools>Edit Geometry menu. If you ask why we support only 2 geometries once at the time it is because something needs to be done with the attributes... and only for 2 polys it is "traceable". stefan ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=679909&aid=3526317&group_id=118054 ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
