I'm using ArcGIS (ArcMap) 10.2 to determine the relative location of points of land to a regulated area. I downloaded a layer (.lyr) file that displays the regulated area, and am able to display that information with my data. However, I am unable to use the data in (or referenced by) the downloaded layer... i.e. I cannot use Spatial Join ("ERROR 000840: The value is not a Feature Layer").
To try to determine what was happening, I attempted to "Open Attribute Table" to look at the specific features, but the "Open Attribute Table" command was not visible. That is, when I right-click the layer name in the table of contents, I don't have the normal options I do for features.
Thus, it seem I am unable to use this layer as I would a normal feature set. Why is this, and how can I still use this data?
FYI: I'm a relative novice at ArcGIS, so perhaps there are fundamental issues I'm not getting?
