You should be aiming for something like this: {   'Rhino1': [(X1, Y1), (X2, Y2), ...],   'Rhino2': [(X1, Y1), (X2, Y2), ...],   ... }‍‍‍‍‍‍‍‍‍ ... View more

Try specifying the entire path for the input raster, rather than relying on the workspace env. If that doesn't work, try running the tool on its own (outside any loop), hardcoding the values that you think should work, and work backwards from there. Things I see that can make easy mistakes in your code: concatenating path components (should try to use os.path.join), using FGDB rasters, relying on envs, specifying a field that probably doesn't exist, and I'm not sure that FGDB rasters are GRID format (although it seems to be working for you). ...

I meant print that in your own script to ensure the values are exactly what you think they should be.  ... View more

Can you double-check that you have the final slash on outrasterpath? If it's missing and not being concatenated properly, you could get an extension error: import os outrasterpath = r"S:/General-Offices-GO-Trans/TEST_RASTERCLIP.gdb" featureClass = "featureClassName" path1 = outrasterpath + featureClass path2 = os.path.join(outrasterpath, featureClass) print(path1) print(path2)‍‍‍‍‍‍‍ S:/General-Offices-GO-Trans/TEST_RASTERCLIP.gdbfeatureClassName S:/General-Offices-GO-Trans/TEST_RASTERCLIP.gdb/featureClassName‍‍‍‍‍‍‍‍‍‍ Try printing the following in the cursor: print(outrasterpath, featureClass, outrasterpath + featureClass)‍ If you could share the entire script, that may expose more hints, too. ...

It seems they're trying to perform raster clip, so this (i.e. management clip) is the correct tool. ... View more

Here's a Python implementation you can tailor to Excel (mostly just need r2, t2, x2, y2). Note the difference between square-rooting the radius (right) and not (left): import matplotlib.pyplot as plt from matplotlib.patches import Circle import numpy as np r1 = np.random.rand(1000) t1 = np.random.rand(1000) * np.pi * 2.0 x1 = r1 * np.cos(t1) y1 = r1 * np.sin(t1) r2 = np.sqrt(np.random.rand(1000)) t2 = np.random.rand(1000) * np.pi * 2.0 x2 = r2 * np.cos(t2) y2 = r2 * np.sin(t2) plt.figure(figsize=(8, 4)) ax1 = plt.subplot(121) circle = Circle((0, 0), 1, facecolor='none',                 edgecolor=(0, 0, 0), linewidth=2, alpha=1) ax1.add_patch(circle) plt.plot(x1, y1, '.', color=(0, 0, 0), alpha=1) ax2 = plt.subplot(122) circle = Circle((0, 0), 1, facecolor='none',                 edgecolor=(0, 0, 0), linewidth=2, alpha=1) ax2.add_patch(circle) plt.plot(x2, y2, '.', color=(0, 0, 0), alpha=1) ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ...

Either use raw strings (r'Z:\...') or forward slashes in your paths. I'm guessing nothing triggers the if statement, or possibly nothing is read into walk, at all, because the paths are incorrect. ... View more
