More information on ldm-mcidas can be found in the LDM-MCIDAS web pages: http://www.unidata.ucar.edu/packages/mcidas/mcidd/ldm-mcidas.html Relevant links are: Installation Instructions http://www.unidata.ucar.edu/packages/mcidas/mcidd/ldm-mcidas-install.html Download the software http://www.unidata.ucar.edu/packages/mcidas/mcidd/ldm-mcidas-download.html Binary distributions of ldm-mcidas are available for a large set of platforms supported by Unidata. If your machine is not on the list of supported platforms, then you may need to build ldm-mcidas decoders from source. In this case, you would need to have McIDAS installed on your workstation. It is unlikely, however, that you have such a platform. >Also, I note the MCIDAS label. Do we need >Mcidas installed to aquire this type of product with ldm? No. The LDM feed type is named MCIDAS since the imagery were originally broadcast (in the Unidata-Wisconsin datastream, LDM feed type MCIDAS) for use by McIDAS workstations. GEMPAK can display a subset of imagery that is supported by McIDAS. All of the images in the Unidata-Wisconsin datastream are included in this subset. Tom Yoksas
