O'Reilly Webcast: Web Squared

Hvad er web gange web?
/Sik

What is the web times the web?
/Sik

Quote

Tim O'Reilly and John Battelle explore their vision of where the web is heading: As we approach the six-year mark from the original Web 2.0 thesis, the trends are becoming clearer than ever. Once applications live in the cloud, the key to success will be harnessing network effects so that those applications literally get better the more people use them. But that's just the beginning. Today we see that applications are being driven by sensors, not just by people typing on keyboards. They are becoming platforms for collective action, not just collective intelligence. The "data shadows" that people and things leave in cyberspace are becoming richer and deeper, and are being exploited in new ways. All this is adding up to something profound and different. When web meets world, we get Web Squared.

Quote

The new ArcGIS Online site went public beta earlier today, and the latest post on the ArcGIS Online blog provides a great introduction to using and leveraging the site, including some specific examples using the soon-to-be released new version of ArcGIS Explorer.

Shown below is ArcGIS Explorer with a layer package that was published by ESRI and discovered and accessed from ArcGIS Online.

Note that shared resources you will find on ArcGIS Online, such as layer packages, layer files, add-ins, Explorer layers, and more will open in ArcGIS Explorer 900 only and are not intended to be used with ArcGIS Explorer 500.

2009 ESRI International User Conference - Q & A

Med 9.4 kan du få direkte adgang til dine native spatiale data via din iPhone ...
/Sik

With 9.4 you'll get direct access to your native spatial data via your iPhone ...
/Sik


Quote
Q: Will ESRI support the iPhone?

Yes, we will support the iPhone as a mobile platform to get maps from ArcGIS Server and do queries and edits on data from ArcGIS Server. We plan on releasing an application for the iPhone later this year and then adding additional capability as part of our 9.4 release. In addition developers can build their own solutions for the iPhone using the REST APIs available from ArcGIS Server. [...]

Q: When will ESRI support direct access to the spatial types within relational databases (i.e. SQL 2008, Oracle Spatial, etc) that are not geodatabases (i.e. does not utilize ArcSDE technology)?

At 9.4, ArcGIS introduces new functionality called “query layers” to allow users to directly access spatial type data stored in a database that is not a geodatabase. Query layers allow users to use a SQL query to access spatial type data and create a new (read-only) layer in ArcMap. This layer will allow users to map, query, and analyze data from spatially enabled databases such as SQL Server, Oracle, PostgreSQL, DB2, or Informix without registering the spatial information in a geodatabase or installing and configuring ArcSDE.

Additionally, geodatabase users who store their spatial information in spatial types can use this functionality to work with their data using complex SQL queries. [...]

By Joe Francica and Adena Schutzberg

This past week two geospatial practitioners were cited for their good work by the FBI. What did they do? At the request of the Bureau, they went online and found some Digital Raster Graphics, scanned quad maps, printed them and gave them to agents working in their area. Is this how agents and others in the federal government, or even citizens, should get their geographic data? What does this scenario reveal about the FBI? The state of our geospatial infrastructure? The value of the geospatial workforce? [...]

Cambridge Mobile Urban Sensing

Hvad med at udstyre alle offentlige transportmidler (busser og tog) med lignende måleinstrumenter?
/Sik

What about equipping all public transports with similar devices?
/Sik

Quote

CamMobSens is the Cambridge end of the MESSAGE project, a collaboration between Cambridge University, Imperial College London, Leeds University, Newcastle University and Southampton University. In Cambridge we mount sensors on pedestrians and cyclists to monitor pollution and send back the information to a website as soon as it is gathered.

carbon monoxide (CO)
nitrogen monoxide (NO)

Here's a short, speeded up movie (1.9MB, MOV format) of someone with a nitrogen dioxide (NO2) sensor walking around Cambridge. The data is transmitted from the sensors via Bluetooth to Nokia mobile phones, for which we write Python applications under Symbian, and then via GPRS to a PostgreSQL database. It can then be extracted in KML format and displayed in Google Earth (as in the pictures and movie above).

A transcript and podcast of a BBC radio programme that covered this work can be found here.

Building the Next-Generation Web Experience

GIS og kort på nettet har ikke forandret sig meget siden internettets start i 90'erne ... Kort på nettet ligner kort som vi kender dem fra papir ... De er dog blevet 'intelligente' og man kan interagere med dem, men i bund og grund har de stadig samme form som de kort man finder på reolen derhjemme. Google gik skridtet videre og genopfandt globussen, men som sagt ikke noget unikt for nettet ... Hvad er GIS's sande form på nettet?
/Sik

GIS and maps on the net haven't changed much since the dawn of the internet in the early nineties ... Maps still looks like maps as we know them from print ... They have become 'intelligent' and they do interact but in essense they are still like the maps we find on our shelves at home ... Google reinvented the globus but that's no unique internet feature ... What is the true identity of GIS on net?

She said that the ideal Web experience of the future will be Customized, Aggregated, Relevant and Social (with the acronym "CARS" as a mnemonic). She pointed to several services that take advantage of social networking and aggregation to deliver customized and relevant data to users. [...]

Stop imitating paper and be the Web

These sites succeed by taking full advantage of the Internet. "New forms of technology start by imitating older forms and then evolve into their true forms," said Dorsey.

As an example, she pointed to theBenz Patent Motorwagen of 1886which looks more like a carriage than a modern day car. Even the famous Ford Model T required a hand crank to start. "The Austin 7 RK Saloon of 1928 was a car that you or I could start." She meant that in the Austin 7, the controls were located where a modern driver would expect them to be.

The first Web page appeared in 1991. In 1992 it still looked like a piece of paper.

"We've been working on the Web for ten years," said Dorsey. "It took the car 50 years to find its true form. The online experience has yet to find its true form."

Is Google Maps GIS?

Google maps was launched in November 2005. Thus began the rapid expansion of the geo-industry. Yahoo and Microsoft soon entered the market. Mapquest extended its offering and ESRI broadened their business. All made public their mapping API’s. Slippy tiled base maps became easy to add to any web sites. But are these consumer maps, often described as mash ups, GIS? This has been much discussed on the Web (http://highearthorbit.com/is-googlemaps-gis/). Though there are many differing opinions, the general agreement is that the boundaries are rapidly blurring. It might be worth for this discussion, to include these new, currently free tools. [...]

Launching Maplines

Cuil ... jeg havde fuldstændig glemt denne Google killer søgemaskine ... Geolokalisering af søgeresultaterne er ikke nyt, men hvis Cuil kan gøre det bedre end vi hidtil har set det har de måske en fremtid ...
/Sik

Cuil ... I had totally forgotten about this Google Search Engine killer app ... Geo localization of the search results is of course no new but if Cuil can do it better than seen so far it may have a prosperous future ...
/Sik

Quote

Cuil continually strives to bring the information you are looking for from the depths of the Internet to the first search results page. One of our goals is to extract structure from the unstructured web and present it to you in an informative, visually appealing and accessible way. Today, we announce the launch of our newest feature in this direction — Maplines.

You might be thinking, “What in the world is a Mapline?” Just as our Timelines show a concept across time, our Maplines show a concept across a map.

A search for bird watching results in a map with points across the world which relate to bird watching. Let’s look at some of them:

  • Krabi Province, Thailand: There are many hard-to-find birds such as: Gurneys, Finfoots, Bigwinged Brown Kingfishers, Egrets, Bitterns and Herons etc.
  • Yell, Shetland, Scotland: Bobby Tulloch, perhaps the best known resident of Yell and noted Shetland ornithologist, who rocked the bird watching establishment, by discovering a pair of breeding Snowy Owls on neighbouring Fetlar when working as a tourist guide.

We make it easy to explore the concept you searched for and how it relates to a particular location on the map—hovering your mouse over a pin will result in a pop-up with a longer description and a link to search for related pages.

Here are some queries that result in Maplines:

We hope our data mining experiments and features are helping you find the information you are looking for and explore areas of interest in a more visual way. As always, we’d love to hear from you.

Let's make the web faster

Hvad der var hurtigt igår er dræbende langsomt imorgen ... Men hvor meget er indhold og hvor meget er udenom snak ??
/Sik

What felt fast yesterday may feel snailish tomorrow ... But how much is content and how much is wrappings ??

From building data centers in different parts of the world to designing highly efficient user interfaces, we at Google always strive to make our services faster. We focus on speed as a key requirement in product and infrastructure development, because our research indicates that people prefer faster, more responsive apps. Over the years, through continuous experimentation, we've identified some performance best practices that we'd like to share with the web community on code.google.com/speed, a new site for web developers, with tutorials, tips and performance tools.

We are excited to discuss what we've learned about web performance with the Internet community. However, to optimize the speed of web applications and make browsing the web as fast as turning the pages of a magazine, we need to work together as a community, to tackle some larger challenges that keep the web slow and prevent it from delivering its full potential:
  • Many protocols that power the Internet and the web were developed when broadband and rich interactive web apps were in their infancy. Networks have become much faster in the past 20 years, and by collaborating to update protocols such as HTML and TCP/IP we can create a better web experience for everyone. A great example of the community working together is HTML5. With HTML5 features such as AppCache, developers are now able to write JavaScript-heavy web apps that run instantly and work and feel like desktop applications.
  • In the last decade, we have seen close to a 100x improvement in JavaScript speed. Browser developers and the communities around them need to maintain this recent focus on performance improvement in order for the browser to become the platform of choice for more feature-rich and computationally-complex applications.
  • Many websites can become faster with little effort, and collective attention to performance can speed up the entire web. Tools such as Yahoo!'s YSlow and our own recently launched Page Speed help web developers create faster, more responsive web apps. As a community, we need to invest further in developing a new generation of tools for performance measurement, diagnostics, and optimization that work at the click of a button.
  • While there are now more than 400 million broadband subscribers worldwide, broadband penetration is still relatively low in many areas of the world. Steps have been taken to bring the benefits of broadband to more people, such as the FCC's decision to open up the white spaces spectrum, for which the Internet community, including Google, was a strong champion. Bringing the benefits of cheap reliable broadband access around the world should be one of the primary goals of our industry.
To find out what Googlers think about making the web faster, see the video below. If you have ideas on how to speed up the web, please share them with the rest of the community. Let's all work together to make the web faster!
