<p>This demo uses the OpenLayers GeoRSS parser, which supports GeoRSS Simple and W3C GeoRSS. Only points are |
|---|
| 42 |
currently supported. The OpenLayers GeoRSS parser will automatically connect an information bubble to the map |
|---|
| 43 |
markers, similar to Google maps. In addition, the parser can use custom PNG icons for markers. A sample GeoRSS |
|---|
| 44 |
file (georss.xml) is included. |
|---|
| 45 |
|
|---|
| 46 |
<form onsubmit="return false;"> |
|---|
| 47 |
GeoRSS URL: <input type="text" id="url" size="50" value="georss.xml" /> |
|---|
| 48 |
<input type="submit" onclick="addUrl(); return false;" value="Load Feed" onsubmit="addUrl(); return false;" /> |
|---|
| 49 |
</form> |
|---|
| 50 |
|
|---|
| 51 |
<p>The above input box allows the input of a URL to a GeoRSS feed. This feed can be local to the HTML page -- |
|---|
| 52 |
for example, entering 'georss.xml' will work by default, because there is a local file in the directory called |
|---|
| 53 |
georss.xml -- or, with a properly set up ProxyHost variable (as is used here), it will be able to load any |
|---|
| 54 |
HTTP URL which contains GeoRSS and display it. Anything else will simply have no effect.</p> |
