This is very easy in McIDAS-X 7.7 as one can specify a dataset of images in AREA format but not using AREA naming conventions. It is a little more cumbersome in version of McIDAS previous to 7.7, but still pretty easy. >When we open them in NSAT >we can see some resemblance of the anticipated data, but certainly not >what we were expecting. > >Some sample images can be found at: >ftp://opwx.db.erau.edu/pub/faculty/herbster/areafiles/ > > >Could someone please help me to: >1) determine if these are valid area files I grabbed: cmx3g8_ir_1998.271_1645_mcidas.ara and created an ADDE dataset with it as its only member and loaded it with no problems in McIDAS-X 7.7. So, if this file is like the others, they are in AREA file format. >2) properly decode/view the images in any/all of GARP, NSAT, and/or >McIDAS For McIDAS: o create a directory into which the images will be put; for sake of argument, let's call this directory /data/CAMEX3 o put the files in the directory just created o make sure that the files are at least readable by the user 'mcidas' In McIDAS-X 7.7: o create an ADDE dataset composed of the images: <login as 'mcidas'> cd workdata dsserve.k ADD CAMEX3/IMAGES AREA DIRFILE=/data/CAMEX3/cmx\*.ara \"CAMEX3 images from NASA imglist.k CAMEX3/IMAGES.ALL In McIDAS-X previous to 7.7: o cd /data/CAMEX3 ln cmx3g8_ir_1998.271_1215_mcidas.ara AREA0001 ln cmx3g8_ir_1998.271_1245_mcidas.ara AREA0002 ln cmx3g8_ir_1998.271_1315_mcidas.ara AREA0003 ln cmx3g8_ir_1998.271_1345_mcidas.ara AREA0004 ln cmx3g8_ir_1998.271_1415_mcidas.ara AREA0005 ln cmx3g8_ir_1998.271_1445_mcidas.ara AREA0006 ln cmx3g8_ir_1998.271_1515_mcidas.ara AREA0007 ln cmx3g8_ir_1998.271_1545_mcidas.ara AREA0008 ln cmx3g8_ir_1998.271_1615_mcidas.ara AREA0009 ln cmx3g8_ir_1998.271_1645_mcidas.ara AREA0010 <login as 'mcidas'> cd ~mcidas/workdata dsserve.k ADD CAMEX3/IMAGES AREA 1 10 \"CAMEX3 images from NASA redirect.k ADD AREA000\* \"/data/CAMEX3 redirect.k ADD AREA0010 \"/data/CAMEX3 imglist.k CAMEX3/IMAGES.ALL >Thanks to anyone who can help!!!!
