Yahoo Pipes - creating Mash-ups easily


Mashups are very popular right now. But what does the word Mashup really mean? Mashups allows the user to compose imformation from different data sources and represent this combined information in a way he or she defines.

Google promoted this term recently and also created the term maplets which in fact is nothing else than the possibility to use information on the web an display this information on a map, in this case on Google Maps. But also Yahoo offers the possibility to create so called mashups. They provide a tool called Yahoo pipes. This is an visual editor for creating mashups in any variation and for different application fields. I tested it for about 10 minutes and produced a mahsup that visualize new of an austria newpaper on a map. The result is shown here:

The Yahoo Pipe application is easy to use and with some practice you could imagine how the result will look like. The flexibility is quite high. So it is possible to integrate every feed of a homepage. Additionally Yahoo services, like flickr or Yahoo local search are supported. It would be more open and flexible if also services from other companies are integrated. A drawback I noticed is that the result can not be embedded easily into your own homepage or blog. But I think Yahoo Pipes is under development progress and will include other functionallity in the future.

User-friendly Desktop Internet GIS


I’m currently looking for some interesting open source or freeware GIS desktop software. To answer the question about an alternative for ArcGIS, Intergraph Geomedia or MapInfo I will introduce some alternative freeware GIS tools. The first application I found on the net is uDig.

What is uDig?

uDig is an GIS software program produced by a community led by Canadian-based company Refractions Research. It is based around the Eclipse platform and features full layered Open Source GIS. It is written in Java and released under GNU Lesser General Public License.

Project Outline

The goal of uDig is to provide a complete Java solution for desktop GIS data access, editing, and viewing. uDig aims to be:

  • User friendly, providing a familiar graphical environment for GIS users;
  • Desktop located, running as a thick client, natively on Windows, Mac OS/X and Linux;
  • Internet oriented, consuming standard (WMS, WFS, WCS) and de facto (GeoRSS, KML, tiles) geospatial web services; and,
  • GIS ready, providing the framework on which complex analytical capabilities can be built, and gradually subsuming those capabilities into the main application.
