To create a 2 D Gaussian array using the Numpy python module. My rule of thumb is to use $5\sigma$ and be sure to have an odd size. A reasonably fast approach is to note that the Gaussian is separable, so you can calculate the 1D gaussian for x and y and then take the outer ...
The World Atlas of Desertification (Cherlet et al., 2018) suggests that the LP sub-indicator can be calculated using the Land Productivity Dynamics (LPD) approach. LPD was first developed by Ivits and Cherlet (2013) and is the methodological basis of the LPDynR tool presented in this ...
This is Amazon MWS-specific information that tells Amazon MWS the algorithm you used to form the string that is the basis of the signature. For Amazon MWS, this value is currently SignatureVersion=2. Timestamp— Each request must contain the timestamp of the request. The timestamp (or ...
