Hey guys,
Silly licensing question for you. From:
http://wiki.openstreetmap.org/wiki/Legal_FAQ, it says:
"If you are using OpenStreetMap data only, we request that your credit
reads at least "Map data (c) OpenStreetMap contributors, CC-BY-SA". "
And by default, OpenLayers maps using OSM display the credit, as seen
in this example: http://openlayers.org/dev/examples/osm.html
However, I'm not doing anything out of the ordinary, but that text is
never displayed. Here's the initial map setup:
function init(lon, lat, w_city, alt_cities)
53 {
54
55
56 map = new OpenLayers.Map("prelogin-map", { controls: [
57 new OpenLayers.Control.Navigation(),
58 new OpenLayers.Control.PanZoomBar({zoomStopHeight: 4}),
59 new OpenLayers.Control.ScaleLine(),
60 new OpenLayers.Control.Permalink("reset"),
61 //new OpenLayers.Control.MousePosition(),
62 new OpenLayers.Control.OverviewMap()] });
63
64 // See: http://docs.openlayers.org/library/controls.html
65 map.addControl(new OpenLayers.Control.Navigation());
66 map.addLayer(new OpenLayers.Layer.OSM());
67 var point = new OpenLayers.Geometry.Point(lon, lat);
68 var user_circle = new OpenLayers.Feature.Vector(point);
69
70 // See:
http://docs.openlayers.org/library/spherical_mercator.html
71 // if you want more detail on how to correctly render
layers using various projections.
72 point.transform(new
OpenLayers.Projection("EPSG:4326"), new
OpenLayers.Projection("EPSG:900913"));
73 var vectorLayer = new OpenLayers.Layer.Vector("vector layer");
74 map.addLayer(vectorLayer);
I want to display some type of credit, and I was wondering if anyone
else had similar issues.
Thanks,
Joe
