ERDAS IMAGINE right for the job? Report this article as Inappropriate to us !!!Login to Reply


A bit of background first - I'm an experienced GIS Analyst but do not have extensive experience with "strictly remote sensing" software packages...


I am working on a project in the near future whereby I need to identify woody debris (large logs) on a beach in an automated fashion from ~300 digital orthophotos and/or hard copy air photos, and eventually calculate a rough volume of this debris.  I'm looking for the right tool to identify large pieces of debris (over 10ft long) automatically so I don't have to sift through 300 orthos and measure each one / calculate estimated volumes.


Some of this debris will undoubtedly be piled up and will not be very easy to detect, but some assumptions are acceptable when it comes to calculating the volume of these particular piles (such as diameter of individual logs) - we will also groundtruth a small percentage of these debris piles to minimize error.


90% of the woody debris will have a decent contrast to its background (light brown sand or pebble) while 10% will be on the open water.


I know little about automated detection with remote sensing software, let alone how accurate an automated process would be. Am I on the right track thinking ERDAS IMAGINE could achieve this?


If you could recommend any other software package or method that you believe is ideal for this, please post!


Thank you kindly
