WebODM

Just want to report the issues.
Compile and build latest WebODM and ODM and I got following errors:
Data set is Brighton beach. Processing is finished fine without errors

Contours plugin fail with error no mater what settings I am putting :

“Invalid GeoJSON object.”

Elevation Map plugin fail with error:

… but when i set Noise filter to (Do not filter noise 0 meter) it works fine.
or
when change in elevationmap.py

line 137

cv2.getStructuringElement(cv2.MORPH_ELLIPSE, (round(noise_filter_size / dsm.res[0]), round(noise_filter_size / dsm.res[1])))

to

cv2.getStructuringElement(cv2.MORPH_ELLIPSE, (int(round(noise_filter_size / dsm.res[0])), int(round(noise_filter_size / dsm.res[1]))))

works fine with Noise filter param
