Convert file to ascii (lat long data) -- 2

I need you to develop some software for me. I would like this software to be developed for Windows using .[login to view URL] propertary files to ascii, the application shall be able to bulk convert multiple *.ma1 files to one [login to view URL] file the Map Filename Format description is below To translate Latitude Segment to a latitude value. LatSeg = First 5 digits is the latitude segment LatChar = Next Character is N = north, S = south LongSeg = Next 5 digits is the longitude segment LongChar = Next Character is W = West, E = East oneKOfLatitude = 360.0 / EARTHSIZE , EARTHSIZE = 40000kms = 360.0 / 40000.0 How to convert to a latitude value: if LatChar = N Latitude = (LatSeg+1) * oneKOfLatitude; If LatChar = S Latitude = (LatSeg) * oneKOfLatitude; How to convert to a longitude value: NOTE: This uses the latitude value from previous conversion… If LongChar = W Longitude = -180.0 + ((LongSeg-1) * oneKOfLongitude(Latitude)) If LongChar = E Longitude = 180.0 – ((LongSeg+1) * oneKOfLongitude(Latitude) ) Function oneKOfLongitude is: C = cos( Latitude ) * EARTHSIZE oneKLat = ( 360.0 / C ) return oneKLat; Once this conversion is done you will get a latitude and longitude value. This lat,long value is the position of the top left corner of the 1000x1000 meter grid file. The file itself is formatted as 1000 x 1000 of the following c structure. typedef struct { short depth10; // depth value for 1m square byte fish; // fish magnitude data for 1m square byte mag; // bottom magnitude value for 1m square } mapDataType; Example for previous filename of [login to view URL] Latitude = (4782+1) * (360.0 / 40000.0) = 43.047° N Longitude = 180.0 – 8888 * (360.0/(cos(43.047)*40000.0 )) = 70.5410° W Top left corner of the file is at 43.047° N , 70.5410° W Each square meter should be output in the format “longitude, latitude, depth10,fish,mag” Eg 70.5410,43.047,50,1,99 (Assuming depth10=50, fish =1 and mag = 99)
