By the way: How did you manage to show a tif in your browser?
I manage to show the tiff only on Internet Explorer (using
OpenLayers.Layer.Image), but it is not a problem because it is for a
univerity exam..
then you have to add the proj4js javascript library to your application.
Can you show me an example?
*This is the Current Track Layer*:
new OpenLayers.Layer.PointTrack("Tracks", {
projection: geographic,
strategies: [new OpenLayers.Strategy.Fixed()],
protocol: new OpenLayers.Protocol.HTTP({
url: "track.kml",
format: new OpenLayers.Format.KML({
extractTracks: true,
extractStyles: true
})
}),
dataFrom: OpenLayers.Layer.PointTrack.TARGET_NODE,
styleFrom: OpenLayers.Layer.PointTrack.TARGET_NODE,
eventListeners: {
"beforefeaturesadded": function(e) {
// group the tracks by fid and create one track for
// every fid
var fid, points = [], feature;
for (var i=0, len=e.features.length; i<len; i++) {
feature = e.features[i];
if ((fid && feature.fid !== fid) || i ===
len-1) {
this.addNodes(points, {silent: true});
points = [];
} else {
points.push(feature);
}
fid = feature.fid;
}
return false;
}
}
})
Many Thank's

if you want reproject feature coordinates from EPSG:4326 (WGS84) to
other projection than EPSG:900913 (SphericalMercator),

*Betreff:* [OpenLayers-Users] How To: Positionate WGS84 tracks
intoGauss-Boaga Map
Hi, I'm tring to track some gps data into a Gauss-Boaga map, but I
don't manage to put the track on the right place, how can I do?
*This is the Track layer*:
new OpenLayers.Layer.PointTrack("Tracks", {
projection: geographic,
strategies: [new OpenLayers.Strategy.Fixed()],
protocol: new OpenLayers.Protocol.HTTP({
url: "track.kml",
format: new OpenLayers.Format.KML({
extractTracks: true,
extractStyles: true
})
}),
dataFrom: OpenLayers.Layer.PointTrack.TARGET_NODE,
styleFrom: OpenLayers.Layer.PointTrack.TARGET_NODE,
eventListeners: {
"beforefeaturesadded": function(e) {
// group the tracks by fid and create one
track for
// every fid
var fid, points = [], feature;
for (var i=0, len=e.features.length; i<len; i++) {
feature = e.features[i];
if ((fid && feature.fid !== fid) || i ===
len-1) {
this.addNodes(points, {silent: true});
points = [];
} else {
points.push(feature);
}
fid = feature.fid;
}
return false;
}
}
})
*And this is the Gauss-Boaga**Projection*:
var options = {
isBaseLayer: true,
maxResolution: '0.84686783985005',
strategies: [new OpenLayers.Strategy.Fixed()],
displayInLayerSwitcher: true,
size: new OpenLayers.Size(8745, 6696),
numZoomLevels: 20
};
var gauss = new OpenLayers.Layer.Image(
'Gauss-Boaga',
'CTR588140.tif',
new OpenLayers.Bounds(2556348.9846319141797721,
4227924.4383069388568401,
2563754.8438914027065039,4233595.0653625745326281), <?php
//left,bottom,right,top ?>
new OpenLayers.Size(8745, 6696),
options
);
