25.0000 0.00000000 0.00000000 -25.0000 0645512 -2241413 This is a companion text 'World File' for correctly scaling and geo-locating the image-file ProserpineAUS.jpg in UTM coordinates on the 'Incident Commander Pro' GIS map display. Add ProserpineAUS.jpg map-layer to the GIS display. Horizontal (East-West) Scale Factor: 25.0000 meters/pixel Vertical (North-South) Scale Factor: -25.0000 meters/pixel Top Left (NorthWest) Corner location of the image: UTM Zone: 55 (South of the equator) Image Easting: 0645512 m Image Northing: 7758587 m - 10000000 = -2241413 m World File Northing Note: UTM zones south of the equator are referenced from a point 10000000m south of the equator, near the South Pole. For images located south of the equator: Subtract the Top Left (Northwest) corner Image Northing value from -10000000 to provide the World File's Northing value. eg: Image Northing: 7758587 m - 10000000 = -2241413 m World File Northing This negative World File's Northing is used by 'Incident Commander Pro' to correctly locate the image in UTM zones south of the equator.
