1. A method for determining an emission rate of a fugitive gas, comprising:
receiving, from an imaging device, a first gas density image;
detecting the fugitive gas in the first gas density image;
delineating the fugitive gas in the first gas density image;
sending, to the imaging device, instructions for adjusting a bearing of the imaging device bearing to optimize a position of the fugitive gas in the imaging device's field of view;
sending, to the imaging device, instructions for capturing a second gas density image;
receiving the second gas density image from the imaging device;
calculating, based on the second gas density image, the emission rate of the fugitive gas;
prior to sending the instructions for capturing the second gas density image, determining that a percentage of the fugitive gas is present in less than a threshold percentage of a vertical field of view of the first gas density image; and
in response to the percentage of the fugitive gas being below the threshold percentage, sending, to the imaging device, instructions for modifying a zoom of the imaging device so that the fugitive gas is present in more than the threshold percentage of a vertical field of view of the imaging device.
