GeoExt Layer Tree: Showing BaseLayers and Overlay Layer

Be The First To Comment
I was looking for GeoExt's tree example for my project, and I found official tutorials are kind of hard to understand for the GeoExt beginners. On Googleing through the internet, I found nice and easy way of creating tree  structure menu using GeoExt BaseLayer and Overlay layer tree.

Call for Student Volunteers : FOSS4G-NA 2013

Be The First To Comment
Free and Open Source Software for Geospatial North America is calling for Student Volunteers to encourage student participation at FOSS4G-NA Conference 2013 at Marriott City Center, Minneapolis, MN May 22–24, 2013.

Apply by April 1, 2013 to select on random drawing.

As a volunteer, students will be able to participate in all of the conference activities such as  staffing the registration desk or being a room monitor for a session. You will get a complimentary registration to the conference, but you will still need to get yourself to Minneapolis and find lodging.

Applicants need to be a currently registered, full-time student at a college or university in North America. Volunteers may be asked to confirm their student status.To ensure volunteer opportunities are spread across institutions, only one person from each college or university will be selected until all institutions are represented by one student.

Python Scripting for ArcGIS

Be The First To Comment

Python Scripting for ArcGIS is a new text from Esri Press by Paul A. Zandbergen (2013). It isn’t the first Python book for the geospatial community or even focused on ArcGIS, but it is the first that has the Esri logo on it. Much like other recent books on Geo/Python we have seen, it focuses on integrating an introduction to Python with the industry specific materials. As Frank mentioned when he highlighted the book in a previous podcast, this allows users to gain exposure to Python, but it doesn’t fall back on the (in my opinion) bad habit of most programming texts of spending half of the book on the language and concepts before even getting to the application in the specific area. There is a time and place for that approach in Python specific books. When you add another software library to a book, then use it from the get go.

Federal Government GIS and Geospatial Conference 2013

Be The First To Comment

OpenGeo is going to sponsor FedGeo Day 2013 at Washington DC on Feb 28, 2013. The theme of the conference is about Modern Tools for GIS, Geo Data & Cartography, which will introduce you to GIS, cartography, web mapping, and map publishing tools, show you what you can do with them, and walk through how and why government agencies are using them to dramatically improve their mapping, cartography, and GIS projects.

The conference announcement from their newsletter...

OpenGeo is proud to support FedGeo Day, the exciting new conference in Washington DC. The event offers a platform for those who work in or with federal agencies to share their experiences with modern open source geospatial technologies.

We’re looking forward to seeing case studies of how these tools are being used in government, what benefits they bring, and why so many agencies are shifting to open source technology. There will also be interactive demos that explore specific open source tools and applications. The schedule is packed with programming that should be particularly attractive for those for those who make technology decisions within the federal government.

Interactive Map of Freshwater Species

Be The First To Comment

"Freshwater Ecoregions of the World, (FEOW) provides a new global bio-geographic regionalization of the Earth's freshwater biodiversity.  Covering virtually all freshwater habitats on Earth, this first-ever ecoregion map, together with associated species data, is a useful tool for underpinning global and regional conservation planning efforts, particularly to identify outstanding and imperiled freshwater systems; for serving as a logical framework for large-scale conservation strategies; and for providing a global-scale knowledge base for increasing freshwater biogeographic literacy."

"Over a decade of work and contributions by more than 200 leading conservation scientists have produced a first-ever comprehensive map and database of the diversity of life in the world’s freshwater ecosystems. The map and associated fish data – a collaborative project between World Wildlife Fund and The Nature Conservancy." 

For the fish lovers, the map is so cool.  Since you all like might find it just as cool too!!!  It is interactive, click on an ecoregion, it shows threats, species etc.  User is able to change transparency on the image to show terrain behind the ecoregion.  

Oh yeah, there is a complete article that went along with it...
