[geotrellis-user] Joining a Raster and a Vector RDD

[Ken <kssalanio@xxxxxxxxx>]

I have these two RDDs:

• geotiff_tiles: RDD[(String, MultibandGeoTiff)]
  
• shapefile_features: RDD[MultiPolygonFeature[Map[String,Object]]]
  

I want to perform a join on them so I can compare which tiles intersect which features. 

I can index the geotiff_tiles by creating a RDD[(SpatialKey, MultibandTile)], but I don't know how to do the same for the shapefile_features MultiPolygonFeature RDD.

Is there some other indexing in GeoTrellis like RTrees that I can do on both?

Thank you very much!
