Can you use line features to create polygons?
There are several ways you can use line features to create polygon features. You can create a brand new polygon feature class, or you can interactively create polygon features in an existing feature class.
How are polygon boundaries written out in Excel?
Each input polygon boundary will be written out as an enclosed line feature. A multipart polygon will become a multipart line in the output. The attributes of the input features will be maintained in the output feature class. A new field, ORIG_FID, will be added to the output and set to the input feature IDs of each line.
If two polygons share a portion of their boundaries, one output line will be generated representing the shared segment. The line direction will be arbitrary; the LEFT_FID and the RIGHT_FID will be set to the left or right polygon feature IDs accordingly.
What can I use to make polygons in ArcGIS?
If you have an ArcGIS Desktop Advanced license, there are several geoprocessing tools you can use. The most common one is the Feature To Polygon tool, in the Data Management toolbox > Features toolset.
Can a polygon barrier affect only one element?
Point barriers are associated with only one network element, even if the element is coincident with another element. Alternatively, line and polygon barriers affect by default all network elements they cover. Unintended consequences can occur if any of the network elements under line or polygon barriers are overlooked.
How is a restriction polygon barrier used in a network?
A restriction polygon barrier prohibits travel anywhere the polygon intersects the network. One use of this type of barrier is to model floods covering areas of the network and making road travel there impossible. The left side depicts the shortest path between two points.
How do you create polygons in ArcGIS for desktop?
You can create a brand new polygon feature class, or you can interactively create polygon features in an existing feature class. The tasks below are used to create new polygons in empty spaces rather than splitting existing polygons. If you have an ArcGIS for Desktop Advanced license, there are several geoprocessing tools you can use.
