DOWNLOAD: rapidshare.com This one-of-a-kind resource contains 500 pages of jaw-dropping hacks, mods, and customizations. These include creating mashups with data from other sources such as Flickr, building a space station tracker, hacking Maps with Firefox PiggyBank, and building a complete community site with Maps and Earth. Now you can map out locations, get driving directions, zoom into any point on the globe, display real time traffic, and much more
ArcGIS.com provides a great collection of resources and, as Jack explains below, allows other people to discover the work ESRI users are doing.
ArcGIS.com includes a cool website, but as we learned when developing the Geoportal Extension, it also provides a RESTful interface. This meant we could offer users of the Geoportal Extension access to the information others are sharing through ArcGIS.com.
In the Geoportal Extension we allow distributed searches to go to ArcGIS.com. We implemented this early on in our contribution to the Group on Earth Observation
Realizing that many organizations aren’t waiting for yet another portal, we developed a simple mechanism to integrate a search widget into any web page that would allow searching Geoportals. This has resulted in an HTML widget that can be embedded with 2 simple lines of HTML. By default this widget searches the Geoportal it is part of. But hold on, there’s more!
The Geoportal can search external catalogs, including ones that implement the Open Geospatial Consortium (OGC) Catalog Service for the Web (CS-W), but since 9.3.1 it can also search… ArcGIS.com! Try it at the GEO Portal by going to the search page and selecting ArcGIS.com from the ‘search in’ dialog. You’ll notice it searches ArcGIS.com with the keywords you give. This means any Geoportal 9.3.1+ is a client to ArcGIS.com.
But back to the widget.
Directing the searches from the widget to ArcGIS.com is possible by adding a parameter that instructs the Geoportal to direct the searches to the identified remote site. And thus here is a widget that searches ArcGIS.com. All it took was a minimal HTML like this:
<html>
<body>
<p>Search widget for ArcGIS.com >
<script type="text/javascript"
The topic of verbose metadata versus youtube-style metadata (a title and a video) in the context of Spatial Data Infrastructures is not new. Even publishers of geospatial content struggle with the verbose metadata standards that have been created over the years. Those metadata standards were not written with data discovery in mind. They resulted from the need for analysists to fully understand the data they were about to use to ensure it fit their purpose.
With the advent of the content sharing sites like Youtube or Flickr content sharing no longer was limited to the scientific/professional
