I have a map with two layers: one of polygons and one of points (in coordinate pairs). To each point, I would like to match the attributes of the polygon in which it is located (or closest to). I am trying to use the Spatial Join tool. In the Target Features I have put in the points layer and in the Join Features I have put in the polygons layer.

The resulting layer has the coordinates, but unfortunately all attributes are <null>. Any idea why this is happening and how I can get the resulting layer to include the attributes as required?

Here are some screenshots to help understand the problem: The layer of points and layer of polygons are: enter image description here

And the resulting layer, after using the Spatial Join Tool as indicated above is: enter image description here

  • First, your screenshots only show polygons so I have to ask, are you sure the features intersect? What is your join type (intersect, within, nearest..., etc). Are your data in the same coordinate system?

    Have you gone ahead and exported a shapefile out of your .csv Events layer yet? When adding XY data ArcMap creates a spatial data table that does not have an ObjectID, and so cannot perform certain tasks.

  • Do you know if it automatically matches to the closest polygon if a point is not in any of the polygons?

  • You must enter a Search Radius (optional) to match points that do not overlap Polygons.

  • Thanks @klewis, but what if I specify a radius such that there is a point which can be matched to two or more polygons? Does it automatically match to the nearest one?

The solution is to export the data by clicking the .csv layer, Data, and then Export Data. Name the file a ..shp file. Then do the join operation using the Spatial Join Tool using the polygons and the shape file of coordinates. Then it all works out.
