Identify Get dates in 2011 only from the filenames of the MODIS images in //Fred/DataSets/Satellite Image Archive/Gulf of Mexico/Site 23051/Site 23051 MODIS [TODO: need to get the correct date from the filename - gives year and day of year only - ask Marc] Acquire Go here http://lance-modis.eosdis.nasa.gov/imagery/subsets/?subset=USA7 select the date Click 250m for the correct image type (usually Terra full color) When the image displays, click "Download GeoTiff File" and save the file in //Fred/DataSets/Satellite Image Archive/Gulf of Mexico/Site 23051/Site 23051 MODIS/YYYY-MM-DD Georeference MODIS images are already georeferenced, so nothing to do. Take a break and get a cup of coffee :) Clip Clip the georeferenced image TBD: Find a bounding box that is as big as possible without triggering GE to make a superoverlay when you load it Save the clipped file in the same folder as the original and name it: modis_site23051_YYY-DD-MM-clip.tif Evaluate load the clipped image into GE and determine if a slick is visible around the 23051 site Determine if the image is fairly clear of other features that are likely caused by wind or clouds in the vicinity of the 23051 platform - skip the image if there is too much noise to see the slick clearly Annotate If a good slick is visible draw a polygon around the boundary and annotate with arrows Document total length, width at the widest point, and total area Publish Create page on the labs site where you will publish it Put a link to the labs site page in the description of the top folder in the KMZ Write a description of the slick in the labs page and in the KMZ - they should both have the same content and each should have a link that points to the other Look for an NRC report that corresponds to that location and date - and if it looks like a match, put a link to it in the description Save annotated image as KMZ publish KMZ to the labs page |
