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.
How to convert polyline features to polygon features with ArcGIS?
With an ArcGIS Desktop Basic license, use the Merge tool and the Auto-Complete Polygon tool to convert polyline features to polygon features. The image below shows a polyline feature and its attribute table. To convert a polyline feature to a polygon feature with an ArcGIS Desktop Basic license, follow the instructions below.
Which is the best tool to convert polylines to polygons?
The Feature to Polygon tool is available with the Advanced ArcGIS Desktop license while the Construct Polygons tool is available with both the ArcGIS Desktop Advanced and Standard license. The Convert Polylines To Polygon tool is available with the Production Mapping license.
Can you create a polygon from a line?
If you have line features, you can create polygon features from them. For example, you might need to create parcel polygons from lot lines, lakes from shorelines, or street polygons from pavement lines.
Is there a QGIS equivalent to ArcGIS aggregate polygons?
I am looking for a tool in QGIS 2.40 that performs the function ArcGIS refers to as Aggregate Polygons. Basically it takes a group of polygons within a specified distance and creates a concave hull around them. Does anyone know if this functionality (or anything similar) exists within QGIS currently?
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 to create concave hulls in ArcGIS QGIS?
Buffer the polygons by the maximum separation distance required, dissolving the results. Spatially join the original polygons to the buffer output so that each original polygon receives the unique id of the buffer polygon that it falls within. Create concave hulls using the buffer id field as the group field.
Can a new polygon be added to an existing polygon?
The new polygon can share a border with one or more existing polygons, although the polygons must all be from the same layer as the new feature you are creating. There are two construction tools you can use to create adjoining polygons: Auto-Complete Polygon and Auto-Complete Freehand.
What’s the best way to create adjoining polygons?
There are two construction tools you can use to create adjoining polygons: Auto-Complete Polygon and Auto-Complete Freehand. With Auto-Complete Polygon, you can digitize a new polygon that adjoins an existing polygon, using the existing polygon’s geometry and the edit sketch to define the edges of the new polygon.
How to create Thiessen polygons in ArcGIS Pro?
Create Thiessen Polygons 1 Click Analysis > Tools to open the Geoprocessing pane in ArcGIS Pro. 2 Search for the Points To Line (Data Management) tool and click it. 3 Configure the parameters in the Points To Line pane. Select the layer containing the points data for Input Features, that is, VolcanoJapan.
How to construct polygons from the shapes of other features?
Select the features you want to use to construct new polygons. Click Construct Polygons on the Advanced Editing toolbar. Choose the target in which the new feature will be created. If you have feature templates for the layers in your map, click the Template button and click the template to use to create the new feature.
How to create lines from points in ArcGIS Pro?
Use the Points To Line tool to create lines from points, followed by the Feature To Polygon tool to create polygons within line feature boundaries. Click Analysis > Tools to open the Geoprocessing pane in ArcGIS Pro. Search for the Points To Line (Data Management) tool and click it. Configure the parameters in the Points To Line pane.
How are polygons assigned to Lake in ArcGIS?
All island features will theoretically be assigned to the lake they fall within. There is a spatial join function both in the toolbox and in the main interface; the toolbox version gives you a bit more control as to how to perform the join, and how large a radius to consider for each match.
