Calculating spread of invasive species using ArcGIS for Desktop

I have ArcGIS Desktop Advanced and so far have completed the following;


  1. Used Supervised classification on a satellite image to identify the invasive species with field verification. I have converted the raster to a vector polygon to get the area in hectares.
  2. Used Supervised classification in a second satellite image in the same area with a different time stamp and again converted to polygon to obtain area in hectares.


I would now like to;


  1. Determine the rate of spread for this current period between the 2 satellite images/polygons and;
  2. Use this to predict future spread of the species.


Can anybody offer some suggestions of the workflow to use?
