Bonjour
pour adapter un script perl sur le serveur free.fr j'aurais besoin de le traduire en php, mais je ne m'y connais pas assez.
Je m'en remet donc a une bonne ame.
voici ce script :
#!/usr/bin/perl -w
use strict;
use LWP::Simple qw(!head); #so we don't get errors, CGI has a 'head' as well...
use CGI qw(:standard); # then only CGI.pm defines a head()
#resp
#<?xml version="1.0" encoding="utf-8"?>
#<string xmlns="
http://gisdata.usgs.gov/XMLWebService ... >string</string>my $ws_url = '
http://gisdata.usgs.gov/XmlWebService ... tion_Service.asmx/';my $inv = -1000001; #invalid elevation
#
http://gisdata.usgs.net/XMLWebService ... tion_service.asmx/';my $latLng = param('latLong');
my $content = "0.0\n";
my $wsCall;
my $regex = '-*\d*\.\d+'; #validation of lat/long
my $needToCache = 0;
if($latLng) {
my($e) = $inv;
#getElevation via web service call
my @latLong = split(',', $latLng);
my $lat = $latLong[0];
my $lng = $latLong[1];
if(($lat =~ /$regex/) and ($lng =~ /$regex/)) {
$wsCall = $ws_url. "getElevation?X_Value=$lng&Y_Value=$lat&Elevation_Units=FEET&Source_Layer=&Elevation_Only=0";
#call the USGS webservices
$content = get $wsCall;
}
else {
die "invalid coords: $lat, $lng\n";
}
}
print "Content-type: text/xml\n\n";
print "";
if($content) {
print $content;
}
else { (print STDOUT "USGS web-service returned empty page."); }
