Hi Derek, re: > Thanks for your response. No worries. re: > It sounds like my best option is to download the AREA files and > use McIDAS-X to produce the required image. Actually, the easiest thing to do is to access the imagery remotely using the McIDAS ADDE data serving capability. re: > From browsing the website, it seems that the place to go for access > to the AREA files would be: > http://thredds.ucar.edu/thredds/catalog/satellite/VIS/catalog.html Again, no. The best/easiest way to get access to the data when using McIDAS-X, the IDV or McIDAS-V is to programmatically request the data from a McIDAS ADDE server. This is how we make all of the imagery products distributed in the LDM/IDD (images in the UNIWISC (GOES sectors we create and distribute) and NIMAGE (GOES images sectors that are created for use by NWS forecast offices in GINI format) available and also real-time images from our GOES-East and GOES-West ingest systems. re: > However, these are .gini files. Am I pointing to the right location > for the AREA files that you mention? No. The images you are seeing are the ones broadcast in the NOAAPort Satellite Broadcast Network (SBN). These images have been remapped into mostly conical projections for use in AWIPS/AWIPS-II. re: > Perhaps what I need is your Internet Data Distribution (IDD) > UNIWISC data stream, but don't see where that is. Can you provide the > correct url? The IDD is a system built on top of our LDM software. Cooperating LDMs relay data to each other and so fan out distribution of products in real-time. You can get setup, of course, to REQUEST the UNIWISC (and NIMAGE) datastream on an LDM that you run in your shop, but you would only get the image sectors that are in the datastream(s). The other option if time is critical is to programmatically request the data from our GEOS-East/West satellite ingest systems and do the processing of the data locally. The good news is that since you are at UMichigan, you are entitled to download and use Unidata McIDAS-X for free. McIDAS-X is the only software package that we support/maintain/develop whose redistribution is limited by the owners of the software, the Space Science and Engineering Center at the University of Wisconsin at Madison. I would think that the first step would be for us to produce a couple of GeoTiff-formatted images to see if your system can use them directly. I would not want to see you pour a lot of effort into installing and learning a package before you were convinced that it would suit your needs. re: > Thanks again, No worries.
