No. The invocation would be something like: IMGGRD AREA=3203 GRIDF=1000 This should analyze the image onto a "grid" and store the result into the GRID file GRID1000. GRID1000 should be created if it does not already exist. The grid that is created will be written into the GRID file in the next available position (in McIDAS, GRIDs are stored in GRID files, and one accesses them as positions in the grid file). re: > DSSERVE ADD GRID/GOES13GRIDEFFRAD AREA > DIRFILE=/home/rod/mcidas/data/AREA3203 "GRID FILE FOR the effective Area > files" No on three accounts: - the dataset has to be of type GRID - the length of the descriptor portion of the dataset name can be no more than 12 characters in length (GOES13GRIDEFFRAD has 14 characters) - there should be no trailing quote mark I would try: DSSERVE ADD LOC/GRIDS GRID 1 9999 "All gridded data in GRID format re: > GRDINFO LOC/AREAS.3203 STAT No. Given what I outlined above, the invocation would be: GRDINFO LOC/GRIDS.1000 STAT GRID=1 Comments: - this assumes that the grid created is written as the first grid in the GRID file GRID1000 In GRID=n, 'n' will change depending on how many grids are contained in the GRID file. - you can list out the grids in an ADDE GRID dataset using GRDLIST. Example: GRDLIST LOC/GRIDS.1000 NUM=ALL - IMGGRD allows one to create a grid from a portion of an image You will probably want to take advantage of this feature as you are interested in particular portions of images.
