sentence case style in title, readability, added tags

| Dec 4, 2014 at 8:02 | comment | added | Theodore Jones | A bit more detail in the commercial applications I have. Some of the ones on that list of software I linked are Matlab, Mathematica, JMP and other statistics tools, and software development tools such as Visual Studio. | |
| Dec 4, 2014 at 7:38 | comment | added | Theodore Jones | I don't have a copy of eCognition, but I'll check if anyone I know in my lab/university has it because it seems popular for this type of thing. I'm knowledgeable in Python, C and Java. I have a copy of Matlab but I'm pretty much a noob at it. I have access to any of the software on this list softwarelicense.arizona.edu/students , plus, of course ArcGIS. | |

More detail about datasets
|
| Dec 3, 2014 at 7:48 | comment | added | Theodore Jones | I probably should have included some more detail about what I have. The raw datasets I have are: 1.Full las data, and a tiff raster generated from it 2. Visual imagery (like the sample image shown, but covering a much wider area) 3. manual direct measurements of a subset of the trees in the area. From these I have generated: 1. the ground/vegetation classifications 2. the DEM/DSM rasters | |

| Dec 3, 2014 at 2:41 | comment | added | Michael Stimson | You've got more data than the link. Do you have the classified las files or just the DEM/DSM raster (which one?)? It's really not easy to do this with just visual wavelengths with any degree of accuracy. | |
