Excellent. Russ is an old friend of mine, so I can assure you that he does great things and is always looking to help people. >On the other hand, I would like to >work with you for the displays on the big screen (Desktops and >Laptops). OK. The first thing I need to know is what kind of machine you want to run McIDAS on? If it is Linux/Unix, read the rest of this message. If it is Windows, you may be better off using our Integrated Data Viewer (IDV) package. The main reason I say this is that the Windows version of McIDAS that I distribute is the one I get from SSEC with no alterations. The Linux/Unix version, on the other hand, has alot of additions some of which I will be illustrating below. If you are running on Linux/Unix... As I recall, the thing you want to do in McIDAS is combine the display of satellite imagery, radar, and forecast hurricane tracks. I assume you have already familiarized yourself with the use of IMGDISP for displaying imagery, so I won't go into that much here. Overlaying of radar imagery on top of satellite imagery is really not possible in McIDAS since an image serves as a sort of background for other displays. What you can do, however, is use the routine FRMOLAY to display discrete image levels from one image in the graphics plane of the display. This has the same effect as overlaying the radar echos on top of the satellite image. To see how "overlaying" radar echos on top of satellite imagery, try the following: DATALOC ADD RTIMAGES adde.ucar.edu SF 1 ERASE IMGDISP RTIMAGES/GEW-IR LINELE= 296 602 PLACE=C EU=IMAGE MAP FILE=OUTLUSAM MCOL=1 WID=1 GRA=(GRA) BAR (GRA) SU=IRTEMP X COL=7 ORIENT=VER Now, use FRMOLAY to display radar echos from the US national N0R composite on top of the image: DATALOC ADD NEXRCOMP adde.ucar.edu FRMOLAY NEXRCOMP/1KN0R-NAT UNIT=BRIT RAN='3:85,86:96,97:107,108:119,120:130, 131:141,142:153,154:164,165:175,176:187,188:198,199:209,210:221,222:232,233:243,244:255' INT=0 GU=RADAR16_32 This may take some time if your link is slow. In order for this to display correctly, your McIDAS sessionw would have had to been started with 32 graphic levels. To test this out while your session is running, use the GU command: GU TABLE If your listing has 32 entries like: LEVEL COLOR BLUE GREEN RED ----- ---------- ---- ----- --- 0 BLACK 0 0 0 (Graphic background) 1 MAGENTA 255 0 255 2 CYAN 255 255 0 3 YELLOW 0 255 255 4 GREEN 0 255 0 5 RED 0 0 255 6 BLUE 255 0 0 7 WHITE 255 255 255 8 GRAY 127 127 127 9 GOLD 0 187 255 10 PINK 127 127 255 11 AQUAMARINE 147 219 112 12 ORCHID 219 112 219 13 NAVY 115 0 0 14 SKY 255 163 0 15 BEIGE 127 171 255 16 224 128 255 17 WHITE 255 255 255 18 160 64 202 19 128 32 176 20 0 0 144 21 32 16 240 22 32 128 240 23 16 192 240 24 16 64 16 25 32 104 44 26 48 144 72 27 64 184 100 28 80 224 128 29 144 144 0 30 240 240 0 31 65 0 0 32 BEIGE 127 171 255 GU: Done your session is configure with 32 graphic levels. If your listing shows only 16 levels, you should exit and start a new session with 32 levels. Configuring a session is most easily done from the graphical startup menu: mcidas -config The next step was to plot forecast hurricane tracks on top of the combined satellite and radar display. There is no direct facility in McIDAS to plot forecast hurridane tracks, but you can plot the track if you know the series of Lat,Lon points that are forecast. To do this, you would use the PATH command to create a path and then plot it. Here is a quick and simple of the use of PATH: PATH MAKE TEST PATH ADD TEST 1 20 75 PATH ADD TEST 2 25 77 PATH ADD TEST 3 30 80 PATH ADD TEST 4 35 83 PATH ADD TEST 5 40 78 PATH PLOT TEST Before we continue, please let me know what kind of machine/operating system you are trying to use McIDAS on.
