Anyone know of a way to be able to create a new shapefile of points that sit within a polygon, without having to trace along the boundary line to select all thousands of points?

I used the "Count Points in Polygons" tool thinking it would create a point shapefile with the number of points within the polygon I had selected but I was wrong. It actually made an additional polygon shapefile with one feature telling me the amount of points in this location.

Use the Clip option in Vector... Geoprocessing Tools... Clip to clip a point layer to a polygon layer. You'll get a new point layer with just the points that are in the polygons of the polygon layer. That's what you want isn't it?

If I understand this correctly, you could just apply a spatial selection and export the results.

  1. Add both layers to ArcGIS
  2. Select Selection>Select By Location...
  3. Set Selection Method>select features from
  4. Target layer(s): your points
  5. Source Layer: your polygon
  6. Click Apply
  7. Right click your points in the Table of Contents
  8. Select Data>Export Data...
  9. Choose Export:Selected features
  10. Name your new .shp and click OK

You could append this process by choosing a specific polygon (or set of polygons) and spatially selecting your points that only reside within that polygon selection.
