Importing Text Files with Web Links
In an earlier post about Notes we discussed how you can use a few HTML tags to have the Note Text automatically link to a Web site or document. The same syntax can be used in the Description field when importing text files.
In our post the other day about Importing Locations from Text Files we discussed the steps to import a text file, and used the following as our example:
Name, Longitude, Latitude, Description
Mount Saint Helens, -122.216191, 46.277887, Location of Johnston Ridge Observatory
We can modify this text file so that we can automatically open up a link showing the live Mount St. Helens Web cam located at the Johnston Ridge Observatory. To do this, we edit the contents of the Description field as follows:
Name, Longitude, Latitude, Description
Mount Saint Helens, -122.216191, 46.277887, <html><head><meta HTTP-EQUIV="REFRESH" content="0; url=http://www.fs.fed.us/gpnf/volcanocams/msh/images/mshvolcanocam.jpg"></head></html>
The text file is exactly the same as the original, except that we've changed the contents of the Description (highlighted in blue). We've used the same HTML tags that we used in our Notes example to include a link directly to the live Forest Service Web cam. Now when we click the pushpin we'll see the cam in the popup window:
Also, as mentioned in some of our previous posts, the use of HTML tags to create links to Web content will no longer be required with the next release of ArcGIS Explorer.
