I am thinking purely about ease of sharing this python addin. Yes. Then in your add-in use something like: arcpy.GPToolDialog(os.path.join(os.path.dirname(__file__), 'mytoolbox.tbx'), 'MyTool') ...

Freddie, it's not necessary 'stitch together the call to the tool along with its variables' for the eval call. i.e. print eval('int(1.23)') You only need to use the eval call to get a reference to the model/tool, then you just treat the model object as a normal python function and call it as such. i.e. a = int b = eval('int') print int(1.23), a(2.34), b(3.45) 1 2 3 ...

I had a quick look at this and I *think* Darren Wiens​ is right, arcpy.da.Walk (or a combination of arcpy.ListDatasets() and arcpy.ListFeatureClasses() etc.) is the only way to get the Feature Dataset name if you only know the Feature Class name at runtime: Something like: import arcpy,os gdb = r"C:\Temp\Default.gdb" fcs = ["TESTFC",   # standalone FC        "TESTFDFC"] # FC in a feature dataset def get_paths(path):     """Use this if you have multiple FCs to check"""     paths = {}     for dirname,subdirs,files in arcpy.da.Walk(path):         paths.update(zip(files, [os.path.basename(dirname.replace(path,""))]*len(files)))     return paths def get_fd(fc):     """Use this if you only have one FC to check"""     path = os.path.normpath(os.path.dirname(fc))     if  path == ".":         path = arcpy.env.workspace     for dirname,subdirs,files in arcpy.da.Walk(path):         if fc in files:             return os.path.basename(dirname.replace(path,"")) arcpy.env.workspace = gdb paths = get_paths(gdb) for fc in fcs:     print os.path.join(paths[fc], fc)     print os.path.join(get_fd(fc), fc) TESTFC TESTFC TESTFD\TESTFDFC TESTFD\TESTFDFC ...

Files with a .tfw extension are usually "world​ files" that contain georeferencing information for TIFF rasters.  I'm not all that familiar with lidar data formats, but I'd be surprised if a tfw was associated with a las file. Do you have any .tif files as well? You could try right clicking on one of the LAS files in ArcCatalog, selecting Item Description and then export that to FGDC: If that works, you may be able to batch or script all of the LAS files using the Export Metadata​​ or Export Metadata Multiple​ tools  . ...

How much RAM have you got? Make sure you're using 64bit python, 32bit can't make use of much of your RAM. Prebuild the stack then populate it rather than using a list so less memory is required (due to the way numpy makes copies of arrays) i.e stack = numpy.zeroes((nrasters, nrows, ncols), dtype = numpy.some_appropriate_dtype) i=0 for folder, subs, files in os.walk(ws):      for filename in files:          stack[i, nrows, ncols] = arcpy.RasterToNumPyArray(os.path.join(folder,filename)) Even with 64bit and loads of RAM, you'll probably still have issues with memory, you may need to process the timeseries in chunks, i.e the full time series for a portion of the  image. ...
