Oil Storage Estimation with Time-Series L-Band Sar Imagery

Monitoring of Oil Tank Filling With Spaceborne SAR Using Coherent Scatterers

“…To obtain the number of static CSs which match this semicircle, the method previously described in section III-D can be used. Rather than applying this method to the CSs detected in a single image, in this case it should be applied to the static CSs in S. Now, the function with the crosscorrelation values for each layover l can be denoted as f s (l), and the layover l rs for which the highest number of static CSs match such a semicircle can be obtained using equation (16).…”

“…More recently, two publications [16], [17] have introduced methods capable of automatically extracting some information about oil storage from SAR images. The method described in [16] can automatically estimate the vertical displacement over time of the floating roof of oil storage tanks using time series of moderate resolution SAR images.…”

“…More recently, two publications [16], [17] have introduced methods capable of automatically extracting some information about oil storage from SAR images. The method described in [16] can automatically estimate the vertical displacement over time of the floating roof of oil storage tanks using time series of moderate resolution SAR images. For this, a reference point is automatically selected for each storage tank by analyzing the minimum and average amplitude of the time series, and the location of the amplitude peak corresponding to the double reflection at the tank's floating roof is detected for each individual image.…”

“…On the other hand, when using SAR images for monitoring the fill level of oil tanks, the main limitations are not imposed by the sensor, but rather by the accuracy and robustness of the available algorithms that can be employed for extracting this information. The complexity of automatic information extraction from SAR images can be seen by the fact that from the four methods that have been presented in the literature which deal with the estimation of oil storage, only the methods presented in [16], [17] are capable of extracting some of this information automatically without the need of manual interaction. The method introduced in [17] will be considered as the stateof-the-art, as it is the most recent publication and also capable of automatically extracting more information on oil storage.…”
