How do you select points in a polygon?
2 Answers. You can select the points that fall within a polygon by using the Select By Location tool. On the Main Menu toolbar, go to Selection>Select by Location. You’ll want to select features from your point layer are within your polygon layer. From the ArcMap menu: Selection–>Select By Location.
How to select polygons containing points in ArcGIS 10.1?
To build on the great answer by @KevinV, the attached image shows the result of Select Layer by Location in ArcGIS 10.1. The polygons that intersect the points are highlighted in blue. To create a new feature class from the selected polygons, right click on the polygon layer in the table of contents: Data -> Export Data (Selected Features).
How to create new feature from selected polygons?
To create a new feature class from the selected polygons, right click on the polygon layer in the table of contents: Data -> Export Data (Selected Features). Thanks for contributing an answer to Geographic Information Systems Stack Exchange!
What’s the best way to intersect polygons in Excel?
Just set the polygons as the target layer, the points as the collection layer. There are a variety of options that would probably work for you for the’Spatial selection method’. ‘Intersect’ is the default and will work but it will also return points that occur on the border of the polygon. That’s it, quick and easy, no programming necessary!
How do you draw a polygon in ArcGIS?
Draw a polygon using custom polygon Click Polygon. Place the pointer on the map and click the location of the first point to start drawing. Move the pointer to the next point and click. Continue clicking at each corner of the shape until you have created the polygon. Note: Three points are required to create a polygon.
What does it mean to draw a polygon?

How do you clip points on a polygon?
A very simple approach is to just clip the points layer with the polygon layer (giving a new layer with just the points which lie within the polygon). go Vector->Geoprocessing Tools->Clip. You can use “Vector->Research tools-> Select by location” to select all the points intersecting with your “region not of interest” polygon.
What happens if you buffer a polygon by 0.0?
For polys e.g. polygon landmarks, you can also use the sometimes faster hack that buffering anything by 0.0 except a polygon results in an empty geometry collection. (So a geometry collection containing polys, lines and points buffered by 0.0 would only leave the polygons and dissolve the collection shell.)
