B & W maps Coordinates needed to transform between image pixel and latitude/longitude Note: the screen coordinates are measured from the lower left corner of the image. If you need them from the upper left corner just subtract the iy values from the image size in y (Netscape shows the image size). ix1 ix2 iy1 iy2 lon1 lon2 lat1 lat2 AL 80 516 80 770 -88.7000 -84.7951 30.0000 35.2065 AK 80 770 80 747 -170.0000 -128.9500 54.0000 72.0113 AR 80 770 80 660 -95.0000 -89.4931 32.8000 36.6048 AZ 80 650 80 770 -115.0000 -108.4920 31.0000 37.5069 CA 80 651 80 770 -124.7000 -113.9920 32.0000 42.3066 CO 80 770 80 594 -109.4000 -101.7920 36.8000 41.2065 CT 80 770 80 596 -74.0000 -71.4969 40.8000 42.2018 DE 80 401 80 770 -75.9000 -74.9989 38.4000 39.9019 FL 80 770 80 726 -88.0000 -79.7917 24.3000 31.1074 GA 80 672 80 770 -85.8000 -80.6936 30.2000 35.2063 HI 80 770 80 535 -160.6000 -154.5510 18.7000 22.4380 IA 80 770 80 544 -96.8000 -89.9917 40.3000 43.7062 ID 80 512 80 770 -117.5000 -110.7920 41.7000 49.2058 IL 80 482 80 770 -91.7000 -87.2917 36.9000 42.7064 IN 80 522 80 770 -88.2000 -84.6956 37.7000 41.9053 KS 80 770 80 471 -102.3000 -94.3917 36.8000 40.3065 KY 80 770 80 416 -89.7000 -81.8917 36.3000 39.3066 LA 80 770 80 724 -94.2000 -88.6931 28.8000 33.2055 MA 80 770 80 533 -73.8000 -69.4946 40.9000 43.0026 MD 80 770 80 465 -79.6000 -74.9942 37.8000 39.8025 ME 80 587 80 770 -71.2000 -66.4941 43.0000 47.5056 MI 80 741 80 770 -90.5000 -82.2917 41.5000 47.6059 MN 80 726 80 770 -97.7500 -88.7917 43.0000 49.6058 MO 80 770 80 708 -96.0000 -88.9917 35.8000 40.8065 MS 80 505 80 770 -91.8000 -87.9952 30.0000 35.2065 MT 80 770 80 494 -116.3000 -103.6920 44.0000 49.2057 NC 80 770 80 362 -84.5000 -75.1917 33.7000 36.8068 ND 80 770 80 532 -104.3000 -96.3917 45.7000 49.2056 NE 80 770 80 437 -104.3000 -94.9917 39.7000 43.3062 NH 80 444 80 770 -72.7000 -70.4972 42.5000 45.5038 NJ 80 432 80 770 -75.6000 -73.7978 38.8000 41.5034 NM 80 697 80 770 -109.5000 -102.7920 31.0000 37.2069 NV 80 584 80 770 -120.5000 -113.4920 34.8000 42.3065 NY 80 770 80 630 -80.0000 -71.7917 40.4000 45.2061 OH 80 732 80 770 -85.0000 -80.2941 38.3000 42.1048 OK 80 770 80 433 -103.3000 -94.1917 33.5000 37.3068 OR 80 770 80 624 -124.7000 -116.3920 41.7000 46.4060 PA 80 770 80 502 -81.0000 -74.4919 39.5000 42.5038 RI 80 595 80 770 -72.0000 -70.9987 41.2000 42.2013 SC 80 770 80 602 -83.7000 -78.2932 31.9000 35.3043 SD 80 770 80 538 -104.3000 -96.2917 42.4000 46.2060 TN 80 770 80 260 -90.5000 -81.4917 34.9000 36.8067 TX 80 770 80 758 -107.0000 -92.9917 25.0000 36.8072 UT 80 622 80 770 -114.3000 -108.7920 36.8000 42.2064 VA 80 770 80 372 -84.0000 -74.9917 36.5000 39.5066 VT 80 559 80 770 -73.8000 -71.1967 42.5000 45.2034 WA 80 770 80 540 -125.0000 -116.5920 45.4000 49.2056 WI 80 770 80 760 -93.0000 -86.2917 42.3000 47.0059 WV 80 770 80 716 -82.8000 -77.4934 37.0000 40.8048 WY 80 770 80 633 -111.3000 -103.7920 40.8000 45.2061
