Update preview_available_images to use the cloud_thresh in the user's settings

[2320sharon]

Update the code max_cloud_cover=95 to be max_cloud_cover=self.settings['cloud_thresh']

       for roi_id in tqdm(selected_ids, desc="Processing", leave=False):
            polygon = common.get_roi_polygon(self.rois.gdf, roi_id)
            if polygon is None:
                raise Exception(f"ROI ID {roi_id} not found in the ROIs GeoDataFrame")
            if polygon:
                # only get the imagery in tier 1
                images_count = count_images_in_ee_collection(
                    polygon,
                    start_date,
                    end_date,
                    satellites=set(self.settings["sat_list"]),
                    max_cloud_cover=95,
                    tiers=[1],
                    months_list=months_list,
                )
                satellite_messages = [f"\nROI ID: {roi_id}"]
                for sat in self.settings["sat_list"]:
                    satellite_messages.append(f"{sat}: {images_count[sat]} images")

                print("\n".join(satellite_messages))

Solution

                max_cloud_cover = self.settings.get("cloud_thresh", 95)
                # convert the max cloud cover to a percentage if it is a fraction
                if max_cloud_cover<1 and max_cloud_cover >=0:
                    max_cloud_cover = max_cloud_cover * 100
                # only get the imagery in tier 1
                images_count = count_images_in_ee_collection(
                    polygon,
                    start_date,
                    end_date,
                    satellites=set(self.settings["sat_list"]),
                    max_cloud_cover=max_cloud_cover,
                    tiers=[1],
                    months_list=months_list,
                )

I just realized why we don't do this. The cloud thresh controls the cloud cover in the individual image, which is not the same as the max cloud cover property in GEE that is the cloud cover for the entire scene beyond just the ROI. This will not work.
