How can I select layer by location AND attributes in ArcMap?

I have a dataset (i.e. a shapefile) containin开发者_C百科g spatial location data (coordinates) and elevation data as well as other attribute fields.

I want to select points which have at least 200m vertical separation (i.e. are at least 200m apart on the z-axis) AND are within 3km of each other.

The aim is to create a new shapefile with all points that have this relationship with 1 or more other points.

Im sure there is a solution to this problem (maybe not using arcmap at all?) but i just cant find it. any help would be greatly appreciated.

You are going to have much better luck asking this question in gis.stackexchange.com. Many more ESRI users/programmers there. As a matter of fact I bet you find your solution there without having to ask the question.

You can run the ArcGIS Near tool on all the points.

Then select by attribute points with Z values of >200m and distance values of <3000m.
