Unfortunately our LDM is not set up to generate any Mcidas products >but this can be rectified by using another LDM via ADDE. I am not sure that I follow this. The LDM conveys data from point-to-point. ADDE can do the same, and it can be the conveyance vehicle used to access data for display/analysis from remote machines running remote ADDE servers. >However, I do >have some satellite imagery in area file format which I would like to >display. How can I import these files into Mcidas and display them? This is very easy. If the McIDAS installation was done completely as we recommend, then each user will have a dataset called MYDATA defined for them. You would determine this by running DSSERVE LIST from a McIDAS session. You would end up with a listing part of which looks like: Group/Descriptor Type Format & Range RT Comment ------------------------ ----- ------------------ -- -------------------- MYDATA/GRIDS GRID GRID 1-9999 All gridded data in GRID format MYDATA/IMAGES IMAGE AREA 1-9999 All images in AREA format MYDATA/RTPTSRC POINT MD 1-9999 All point source data files in MD file format MYDATA/TOPO IMAGE AREA 9000-9019 All topographic images in AREA format If you do not get this, then do the following: DMAP MYDATA.BAT If DMAP does not find MYDATA.BAT, then the installation needs attention. If you do see this, then all you need are to make the definitions in MYDATA.BAT active: BATCH MYDATA.BAT and add McIDAS file REDIRECTions that can locate the AREA files. For instance, let's assume that the AREA files that you have are located in a directory called /data/mcidas (the name/location is not important, the concept is). You would setup AREA file REDIRECTions like: REDIRECT ADD AREA* "/data/mcidas If you already have REDIRECTions for AREA files that are more specific than this (e.g., AREA71* "/var/data/images, or something similar), then you will have to be more specific with your REDIRECTion(s). For instance, if the AREA files you have and want to look at are named AREA2000 - AREA2099, then your REDIRECTion would look like: REDIRECT ADD AREA20* "/data/mcidas and so on. To verify that you can find those AREA files, next run: DMAP AREA You should see your files in the list. If you do, then you can access the files using the MYDATA/IMAGES dataset name. For instance, if you have the AREA file AREA2015, you could look at it with: IMGDISP MYDATA/IMAGES.2015 EU=IMAGE MAG=-2 REFRESH='EG;MAP SAT' >Thanks for any assistance Please let me know if the above wasn't clear enough.
