Remarks

The MAP command uses two sets of map files. The US*.MAP files (for example, USCOUNTY.MAP) are used only when the STATE, COUNTY, MARINE or ZONE keyword is specified. The OUTL* files (for example, OUTLSUPU) are used in all other cases. The US*.MAP files include all U.S. counties and National Weather Service zones and marine regions, and slightly different state boundaries than the OUTL* files. The US*.MAP files are derived from the National Weather Service AWIPS Map Database (http://www.nws.noaa.gov/geodata/).

If you want to draw a map using the frame's current navigation, specify L, H, VH or SAT (or X, since SAT is the default) for the map parameter. For example, running MAP with no parameters or keywords draws a map using the frame's navigation. MAP SAT STATE=KS draws the state of Kansas if it's present in the frame's navigation.

If you want to draw a map that defines new navigation for the frame, specify one of the predefined maps (for example, MID, USA, WORL) or DEF for the map parameter. The LAT and LON keywords define the domain for the DEF map. If you also include the STATE, COUNTY, ZONE or MARINE keyword, only the specified states, counties, zones or marine regions are drawn, if they're in the domain.

The STATE, COUNTY, ZONE, and MARINE keywords are used to draw only the specified states, counties, zones and marine regions using the US*.MAP files. These keywords do NOT define the map's domain. Domain is defined with the positional parameter map, using a predefined map, SAT, MID, USA, for example, or using DEF with the LAT and LON keywords. For example, MAP MID STATE=IA defines a domain consisting of the Midwest, but only draws the state of Iowa. If you then run MAP SAT STATE=ALL, all states in the domain are drawn using the USSTATE.MAP file.

When you specify the COUNTY or ZONE keyword, only the counties or zones are drawn; the outlines of the states and/or marine regions they're in are not drawn. Specify the STATE keyword without the COUNTY or ZONE keywords to draw state outlines. Specify the MARINE keyword without the ZONE keyword to draw marine region outlines and the zones within them.

You can specify a single frame or multiple frames in the GRA keyword using the list format (frame1 frame2 frame3. .) and the range format (bframe-eframe). For example, a map is displayed on frames 1 through 5 with any of the following: GRA=1 2 3 4 5, GRA=1-5, GRA=1 2-4 5.

Frame-oriented maps (H, L, LALO, SAT, or VH in the map parameter) always use the navigation of the single frame specified in the IMA keyword, even if multiple frames are specified in the GRA keyword.

If you have multiple panels on a frame, you can display maps on a range of panels by specifying beginning and ending panel numbers with the global keyword PAN. For example, MAP NA PAN=1 4 draws a map of North America on panels 1 through 4. If you specify a frame-oriented map (H, L, LALO, SAT, or VH) in the map parameter and a range in the PAN keyword, the maps may be different because each uses the navigation of the panel it's drawing to. For example, MAP H PAN=2 4 draws a map on panel 2 using the navigation for panel 2, draws a map on panel 3 using the navigation for panel 3, and draws a map on panel 4 using the navigation for panel 4.

The coverages, projections, colors and line widths for the predefined maps listed in the map parameter (EUR, EURB, EURO, MID, NA, POLI, PRC, PRCB, USA, WIS, WORL, and the 50 two-letter state post office abbreviations) are set in the text files MAP.CORE, MAP.SITE, and MAP.USER. The .CORE file is supplied with McIDAS-X and should not be modified. The .USER file overrides the .SITE file, which overrides the .CORE file. This order of precedence allows you or your site to change existing settings and/or add new maps in your .USER or .SITE file. To create a .USER or .SITE file, copy the .CORE file from ~mcidas/data to your $HOME/mcidas/data directory (or another MCPATH directory) and edit the existing predefined maps and/or add new ones.


Labels

The LABEL keyword defines the format and colors of the map's latitude and longitude labels. LABEL=NO omits the labels. The five options for the scheme parameter are described below.


Projections

The pseudo-Mercator projection has equidistant latitude lines; otherwise it is the same as a true Mercator projection. The Lambert conformal projection includes polar stereographic projection as a special case. If you enter only one positive SLAT value or if you accept the default of 60°, the projection is polar stereographic with the North Pole as the origin of projection. If you enter only one negative value for SLAT, the origin of the polar stereographic projection is the South Pole. You must enter two SLAT values to obtain a general Lambert conformal projection. If SLAT1 + SLAT2 > 0, the North Pole is the origin of projection. If SLAT1 + SLAT2 < 0, the South Pole is the origin of projection.

For some values of keywords LAT, LON, SLON and SLAT, the area defined cannot be found. If this happens, an error message is displayed and the program stops. Use SLON for CONF projections only. The default value is computed by assuming that the standard meridian is located in the middle of a box set by two points and is parallel to the left and right edges of the TV screen. If a map is centered, the default SLON is equal to LON.

The examples below are divided into four groups that include satellite, pseudo-Mercator, polar stereographic and general Lambert conformal projections.

This entry draws a high-resolution map in graphics color level 7 with dashed lines. The dashes are each two pixels in length with gaps of eight pixels between the dashes.

MAP VH GRA=1-12

This entry draws a high resolution map on graphics frames 1 through 12. The map is identical in all 12 frames because it uses the navigation for the current image frame.

MAP VH IMA=1 GRA=1-12

This entry draws a high resolution map on graphics frames 1 through 12. The map is identical in all 12 frames because it uses the navigation for image frame 1.

MAP X 5 LALO 6 INT=5 10

This entry draws a map on a satellite image in graphics color level 5. It draws latitude/longitude lines in graphics color level 6 and labels them. The interval for latitude lines is 5°. The interval for longitude lines is 10°.

MAP USA X LALO LABEL=NO

This entry draws a high resolution USA map and latitude/longitude lines without labels.

MAP STATE=OH IN

This entry draws the states of Ohio and Indiana, if they're present in the current frame navigation.

MAP COUNTY=DANE 'ST CROIX' COLUMBIA STATE=WI

IMGDISP MET/FD LATLON=0 0 MAG=-5 BAND=8; MAP; MAP X 2 FILE=OUTLHPOL

These entries display band 8 of the most recent image in dataset MET/FD, then draw the world coastal boundaries and the world political boundaries contained in the newly-displayed image. The coastal boundaries are drawn in the default graphics color level and the political boundaries are drawn in graphics color level 2.
