I am first and foremost an ecologist working to promote the integrity, stability and beauty of the biotic community. I enjoy finding solutions to problems on this site that I otherwise would not have exposure to in my day-to-day work.

Specialties: Remote sensing, GIS, spatial statistics, big data, wildlife conservation, and landscape ecology. My work focuses mainly on multispectral and Lidar remote sensing for assessing vegetation structure and composition.

+1 This is a really good solution. Please consider adding a few lines of text describing what is going on.

Where did you download the Landsat scenes? What level of processing? Have you done any atmospheric correction?

comment Clump and eliminate classes in a raster in ArcMap or R
It requires a Spatial Analyst license, which you may need to enable in Arc (i.e. if you have the license).

comment Python code to compare two fields in different feature layers?
It would also be helpful to have an example before and after the analysis. Often it is helpful to generate a small, simplified subset of fake data that we can use to test scripts out on.

comment Floating point to 8-bit unsigned raster conversion using ArcGIS for Desktop or ERDAS IMAGINE?
+1 Option 2 is a pretty slick way to do the conversion!

In this case, rescaling data is very easy in Erdas--it eliminates a few steps that you describe using ArcGIS. Any type of bulk image processing is almost always more efficient and easier in Erdas. It is definitely worth a look.
