<br />A transformation to or from UTM using a coordinate transformation package can be <br />controlled by specifying the UTM zone or by supplying the geographic coordinate <br />in parameters 1 and 2, from which the UTM zone is computed. FEMA OLGs require <br />both to be present. The parameters are encoded as packed, degrees-minutes~ <br />seconds (OMS) as follows: <br /> <br />degrees * 1000000 + minutes * 1000 + seconds <br /> <br />Example: If degrees - +50, minutes - 30, and seconds - 36.25, then the parameter <br />value is 50030036.25 stored as a REAL*8 variable, and "bbbO, 5003003625000000 08" <br />encoded in FORTRAN 024.15 format. <br /> <br />Control Point Label with Latitude and Longitude and X Y Coordinates: <br /> <br />Oefines a list of four control points, one for each corner of the map sheet with <br />their latitude and longitude values in decimal degrees and the corresponding X,Y <br />coordinates of each point in units of the ground planimetric coordinate system. <br /> <br />Oata Categorv Identification Record: <br /> <br />Identifies the data category. Dptions are: <br /> <br />Flood Hazard Zones <br />Political Areas <br />Map Panel Areas <br />FEMA Hydrography <br /> <br />An example of a header file is as follows: <br /> <br />FEMA-FIRM MAP PANEL AREAS <br />SHERWOOO POINT, CT-NY <br /> <br />FAIRFIELD CO, CT <br />1992 <br /> <br />09001 <br />24000 <br /> <br />3 1 18 2 0.610000000000+00 4 0 4 1 <br />-0.7301804500000000+08 0,4100304500000000+08 0.0000000000000000+00 <br />0.0000000000000000+00 0.0000000000000000+00 0.0000000000000000+00 <br />0.0000000000000000+00 0,0000000000000000+00 0.0000000000000000+00 <br />0.0000000000000000+00 0,0000000000000000+00 0.0000000000000000+00 <br />0.0000000000000000+00 0.0000000000000000+00 0,0000000000000000+00 <br />0.100000000000+01 0,000000000000+00 0,000000000000+00 0.000000000000+00 <br />SW 41,000000 -73,375000 636671,25 4539816.86 <br />NW 41.125000 -73.375000 636412.66 4553693.75 <br />NE 41,125000 -73,250000 646906,37 4553897.09 <br />SE 41.000000 -73.250000 647184.87 4540020,07 <br />MAP PANEL AREAS 0 8 8 010 6 6 OlQ" _ 12 12 1 <br /> <br />10/93 <br /> <br />9 <br />
