NAME xm_station - Station format for the xmap8 program SYNOPSIS xm_station - Input File Format DESCRIPTION There are 4 different station file formats allowable in xmap8. Files are checked prior to importation, so the for- mats must be adhered to strictly. You can get point files loaded by using the -R station_file option. If you use the -r station_file symbol each station file will be plotted with corresponding symbol. FORMAT STATION file is organized on the UW format (university of Washington) Can have Several Station Files input. Use: -R file1 -R file2..... (R = Receiver) The default station format (the one I use for most of my work) is: Example: Name lat. long. elevation(km) 0...|....1....|....2....|....3....|....4....|.. (Card Column) S1V 36N00.7852 117W48.1522 1.197 S1N 36N00.7852 117W48.1522 1.197 S1E 36N00.7852 117W48.1522 1.197 S2V 36N02.0210 117W47.3002 1.224 However, the program can read station files in 3 other formats: These must be very RIGIDLY FORMATTED if xmap8 is to properly distinguish them. Xmap8 needs to see the fields in the correct card columns so that it determine the incoming format. Else all hell breaks loose. This is done so the user does not have to specify a format in advance, but the convention must be adhered to ridgidly! NOTE: You must insert an elevation. Use 0 if you do not have one. Example follow: ==> My format: sta.hel <== 0...|....1....|....2....|....3....|....4....|....5....|....6....|....7.$ AAB 48N44.2020 121W48.6720 0.000 ALB 49N16.3078 124W49.6618 0.026 ==> UW malone.sta <== 0...|....1....|....2....|....3....|....4....|....5....|....6....|....7.$ AAB 48 44 12.12 121 48 40.32 0.000 ALB 49 16 18.47 124 49 39.71 0.020 ==> usn2.sta <== 0...|....1....|....2....|....3....|....4....|....5....|....6....|....7.$ AAB 48.7367 -121.8112 0 ALB 49.2718 -124.8277 20 ==> usn1.sta <== 0...|....1....|....2....|....3....|....4....|....5....|....6....|....7.$ AAB 48.7367N 121.8112W 0 ALB 49.2718N 124.8277W 20 symbols for stations: 0 = draw_triang = upside down triangle 1 = draw_triang_2 = right side up triangle 2 = draw_square = square 3 = draw_star_david = star of david 4 = draw_ex = X mark 5 = draw_Plus = + mark 6 = draw_Diamond = diamond SEE ALSO xmap8 xm_color xm_hypo xm_map xm_menu xm_origin xm_points xm_raster xm_station xm_well xm_wire xm_xsec xm_ellipse
