greenindex extractor calculates sampling points geolocation and then fetches street view images from google map server and then counts greenness as how many green pixels of images.
In bd-test, we compare the output greenness of green route extractor. However, for the same input test file, sometimes we have different greenness result, even though the output calculation of sampling points remain the same.

In above logs, one result is 27.4, while the other is 27.7. but most of time, the result is 28.1.
need to add log to trace the details of calculation on this sample input file. If it is the nature of calculation (which means the greenness on the same input file can be different), then we need to update the bd-test.
