Slashdot discusses a story named GPS-Based System For Driving Tax Being Field Tested. Their summary: "Apparently, since gas consumption is going down and fuel efficient cars are becoming more popular, the government is looking into a new form of taxation to create revenue for transportation projects. This new system is a 'by-the-mile tax,' requiring GPS in cars so it can track the mileage. Once a month, the data gets uploaded to a billing center and you are conveniently charged for how much you drove. 'A federal commission, after a two-year study, concluded earlier this year that the road tax was the "best path forward" to keep revenues flowing to highway and transportation projects, and could be an important new tool to help manage traffic and relieve congestion. ... The commission pegged 2020 as the year for the federal fuel tax, currently 18.5 cents a gallon, to be phased out and replaced by a road tax. One estimate of a road tax that would cover the current federal and state fuel taxes is 1 to 2 cents per mile for cars and light trucks.'"

From the GeoWeb Guru blog referencing ESRI's announcement : "Have you ever wanted to share some of your great maps with the rest of the world? Or maybe just easily share some of your work with a colleague? Well, the new ArcGIS Online sharing application, now open for public beta access, can be used as a system for sharing, finding and using GIS content across the Web. With ArcGIS Online, you can upload maps, register online map services, create and save Web maps as items for others to share, and discover and use maps published by ESRI and other ESRI users. You can organize and control access to the maps you share by making them public or private, and you can create and join groups."

News Office. gvSIG Project writes "The 5th Edition of the gvSIG Conference, organized by the Regional Ministry of Infrastructure and Transport (CIT), will be held from December 2nd until December 4th at the Feria Valencia Convention and Exhibition Center, and will once again host the eclipseDay.

In these difficult times when collaboration is most important, we cope with the adversities together with the aim of coming out strengthened by them. We continue moving ahead together. This is part of the gvSIG project and through this approach we keep on growing. This is our slogan for the fifth edition of the gvSIG Conference: We keep growing.

The call for papers for the Fifth Edition of the gvSIG conference is now open. As of today communication proposals can be sent to the email address: contacto-jornadas-gvsig@gva.es; they will be evaluated by the scientific committee as to their inclusion in the conference program.
There are two types of communication: paper or poster. Information regarding to regulations on communication presentations can be found in the report's section. Abstracts will be accepted until September 21st .

Organizations interested in collaborating in the event can find information in the section: How to collaborate?"
gvSIG has been mentioned several times in the past, see selected stories below.

This is potentially major news for many geospatial experts. The METI and NASA released today version 1 of the ASTER Global DEM (GDEM). From the 2-pages announcement: "Consequently, the ASTER GDEM is available at no charge to users worldwide via electronic download from the Earth Remote Sensing Data Analysis Center (ERSDAC) of Japan and from NASA’s Land Processes Distributed Active Archive Center (LP DAAC). [...] The ASTER GDEM covers land surfaces between 83°N and 83°S and is composed of 22,600 1°-by-1° tiles. Tiles that contain at least 0.01% land area are included. The ASTER GDEM is in GeoTIF format with geographic lat/long coordinates and a 1 arc-second (30 m) grid of elevation postings. The GDEM is referenced to the WGS84/EGM96 geoid. The GDEM’s pre-production accuracy estimates were 20 meters at 95% confidence for vertical data, and 30 meters at 95% confidence for horizontal data." The spatial extent covered and the spatial resolution are both higher than the also freely available CGIAR-CSI SRTM-DEM Version 4 which is still very pertinent since the ASTER GDEM announcement say "METI and NASA acknowledge that ASTER GDEM Version-1 should serve as an “experimental” or “research grade” product".

Matt Sheehan writes "At the recent excellent Where 2.0 conference, I noted a number of repeated themes; the challenges of the current economic downturn, the development of rich internet mapping applications (RIA's), new tool releases and mobile. I thought it might be useful to write an article on low cost solutions to building rich mapping applications across multiple platforms. I have posted the article on my blog" The summary: "There are many low cost solutions available for building geo-spatial applications. This article walked through the GIS stack, discussing some of these options. Increasingly, as budgets tighten, companies are turning to these open source development tools. Often they are surprised by what they find." See also related stories below.

Google
From the spatial sustain blog (go there for the full story) : "Google has announced on their Blog that they’ve made inroads in computer vision, enabling computers to quickly identify images of 50,000 landmarks with 80% accuracy. Google mentions in the post that the effort is aimed at unlocking information from pixels now that they have such a strong handle on unlocking information in text. The ability to catalog and recognize images of the real world plays into the idea of augmented reality and also has implications for building digital city models."
