Rich Internet Application Frameworks for Mapping: An Introduction for Non-programmers

Jeg savner at kunne mashe RIA elementer i browseren og ikke være låst fast på én RIA platform og én RIA applikation ...

I miss being able to mash RIS elements in the browser and not being tied to ONE RIA platform and ONE RIA application ...


By Adena Schutzberg


What's a Rich Internet Application, Anyway?
Rich Internet Application (RIA) is a phrase that distinguishes the more elegant Web apps from the less elegant ones. Different publications list different "properties" for RIAs. This list is from 
Java Today.

The app:

  • is launched from (or even contained within) a Web page
  • provides immediate feedback to users, with no refresh required
  • supports tree controls, tabbed panels, drag and drop, and keyboard navigation usually found in desktop packages
  • used platform independent coding

RIA Frameworks
RIAs are enabled by RIA frameworks, software installed on the client computer. The frameworks manage downloads and updates, and run the RIAs. In the best case scenario, the frameworks are invisible to the user.

There are many RIA frameworks (and some arguments about which technologies are, or are not, RIA frameworks), but the most widely known in the geospatial arena are probably AJAX, Adobe Flash/Flex and Microsoft Silverlight. Soon, we are likely to hear more about Google Gears. [...]

A bit of an app built with the ESRI Silverlight API. Note that the user can set some Silverlight preferences.

Adding search power to public data

Tænk hvis det samme skete for danske 'offentlige' data?

Google made information searchable - the trend over the last few years has been to make data quatifyable and analyzable ... Making them even better suited for GIS ...


Earthquakes are not the only thing that can shake Silicon Valley. After the dot-com bubble burst back in 2000 the unemployment rate of Santa Clara county went up to 9.1%. During the last couple of months, it has gone up again:

We just launched a new search feature that makes it easy to find and compare public data. So for example, when comparing Santa Clara county data to the national unemployment rate, it becomes clear not only that Santa Clara's peak during 2002-2003 was really dramatic, but also that the recent increase is a bit more drastic than the national rate:

If you go to and type in [unemployment rate] or [population] followed by a U.S. state or county, you will see the most recent estimates:

Once you click the link, you'll go to an interactive chart that lets you add and remove data for different geographical areas.


The data we're including in this first launch represents just a small fraction of all the interesting public data available on the web. There are statistics for prices of cookies, CO2 emissions, asthma frequency, high school graduation rates, bakers' salaries, number of wildfires, and the list goes on. Reliable information about these kinds of things exists thanks to the hard work of data collectors gathering countless survey forms, and of careful statisticians estimating meaningful indicators that make hidden patterns of the world visible to the eye. All the data we've used in this first launch are produced and published by the U.S. Bureau of Labor Statistics and the U.S. Census Bureau's Population Division. They did the hard work! We just made the data a bit easier to find and use.

Since Google's acquisition of Trendalyzer two years ago, we have been working on creating a new service that make lots of data instantly available for intuitive, visual exploration. Today's launch is a first step in that direction. We hope people will find this search feature helpful, whether it's used in the classroom, the boardroom or around the kitchen table. We also hope that this will pave the way for public data to take a more central role in informed public conversations.

This is just the beginning. Stay tuned for more.

What's New in ArcGIS 9.3.1




ArcGIS 9.3.1 improves the performance of dynamic map publishing and increases the sharing of geographic information.

High-Performance Dynamic Map Publishing

  • New faster drawing map service
    • Outperforms ArcGIS 9.3.
    • Produces significantly better-looking maps.
    • Shortens map caching time.
  • New Map Service Publishing toolbar in ArcMap helps you tune-up your map documents before publishing to ArcGIS Server.
    • Review and respond to errors, unsupported content, and warnings about items that will slow down your dynamic map services.
    • Preview your map document and estimated rendering time.
    • Save your map document to a map service definition (msd) format, which is optimized for performance in ArcGIS Server.

Better Sharing of Geographic Information

  • Better sharing of layers
    • Layers referencing feature or raster data can be packaged into a single layer package comprised of both the layer file and data.
    • These layer packages can be shared with other users via files, e-mail, or the new ArcGIS Online sharing capability.
    • With ArcGIS Online users can
      • Search for maps published by ESRI and other users.
      • Upload maps and register online map services.
      • Organize and control access to the maps they share.
      • Save Web maps as items for others to share, discover, and use.

Fast Access to Microsoft Virtual Earth Maps and Imagery

  • Quickly start GIS projects with ready-to-use content.
    • Up-to-date multi-scale mapping content from Microsoft Virtual Earth includes aerial imagery, roads, and hybrid (aerial with labels) imagery.
    • Content (imagery, roads, and hybrid) appears as another data layer in GIS providing excellent background maps on which users can overlay their operational data.
    • ArcGIS Desktop and ArcGIS Server users directly connect to Microsoft Virtual Earth content via ArcGIS Online.
    • Clients can access Virtual Earth content from any Web applications built with ArcGIS Server and ArcGIS Server Web SDKs (including JavaScript, Flex, and Microsoft Silverlight APIs).

Enhanced Support for Java Developers

  • Ability to extend the ArcGIS/ArcObjects Framework. Java developers can now create the following extensions in their native language:
    • Custom geoprocessing tools
    • Server object extensions (SOEs) and utility objects for ArcGIS Server
    • Class extensions for customized data behavior in a geodatabase
    • Custom renderers for customized rendering of data in ArcMap and ArcGIS Engine applications
    • Plug-in data sources
  • Tools for debugging, registering and deploying Java extensions for ArcGIS
  • Support for Eclipse integrated development environment (IDE)
    • Wizards to generate boilerplate code based on the developer's specification
    • Autodeploy feature

Easy to Install

  • Upgrading to ArcGIS 9.3.1 does not require uninstalling ArcGIS 9.3.
  • Easy to migrate or work in mixed environments of ArcGIS 9.3 and ArcGIS 9.3.1 within the same organization since geodatabases, map documents, and APIs did not change.

Licensing Changes for ArcGIS Server

With the release of ArcGIS 9.3.1, the following changes in ArcGIS Server licensing will take effect:

  • ArcGIS Server Standard (Workgroup or Enterprise) users will be able to use the editing capabilities of ArcGIS Server.
  • ArcGIS Server Advanced (Workgroup or Enterprise) will include the following extensions for no additional fee:
    • Spatial
    • 3D
    • Network
    • Geostatistical
  • ArcGIS Server Enterprise users will be able to deploy the following components without incurring an additional deployment license fee:
    • Web ADF – SDK or Runtime
    • Web Service Handlers
    • Server Object Manager


ArcGIS 9.3.1 is now available. ESRI will automatically ship ArcGIS 9.3.1 to users current on maintenance.

Dataset of the Day: Obama’s First 100 days




[...] Now that his first 100 days are up, we have updated the dashboard with the latest data on unemployment, home foreclosures, and other indicators of economic health. For foreclosures and unemployment we’ve created maps showing what locations have improved and which have gotten worse during the last 100 days (roughly). There has been improvement in foreclosures in some regions, but unemployment has gotten worse across the board. We’ve also included a new selection called “100 days” that tracks jobs that have been created by Obama policies to date. We’ll continue to track all the indicators and make the data publicly available.

Flickr users make accidental maps

Fascinerende ...

Fascinating ...


Using geotag data attached to 35 million photos uploaded to Flickr, David Crandalland colleagues at Cornell University in Ithaca, New York, created accurate global and city maps and identified popular snapping sites.
Many digital photos are now geotagged– stamped with the latitude and longitude coordinates for the location where they were taken. David Crandalland colleagues at Cornell University in Ithaca, New York, have analysed this data, using 35 million photographs uploaded to the Flickr website

Crandall's team found that the data offered a simple way to organise millions of photos on a global scale. Simply plotting that raw data onto an empty canvas revealed accurate maps, like this one of the 48 lower states of the US. 

Each map is constructed from a small subset of images. The team limited the number of photos they analysed from each Flickr user, to be sure a cluster on the map represented many users visiting a location and not "a single user taking thousands of pictures of his or her backyard", says Crandall. [...]

Jack Dangermond Interview 1 of 3: Web Mapping

'Geo-awereness' lidt mere mundret end 'Spatial awareness' ... 

'Geo awareness' and bit more understandable for non-gis users ...


O'Reilly Radar Logo
by Brady Forrest 

 Jack Dangermond is the founder and CEO of ESRI. ESRI's software is used by every level of government around the world. You can see ESRI's influence in online mapping tools from Microsoft,GoogleYahoo! and FortiusOne. I had the opportunity to interview him over the phone on April 20, 2009. In this portion of the interview we discuss the history of GIS and online mapping.

Jack will be speaking at Where 2.0 on May 20th in San Jose.

Brady Forrest: So ESRI is known for creating large enterprise GIS applications. And then a couple of years ago, maps came into the hand of just about anybody through Google Maps. One question -- I asked people for questions for you, and I think my favorite one was: Do you think that the explosion of web-based mapping has just filled the world with ugly and poorly designed maps?

Jack Dangermond: That's an interesting and compelling question. I think what the consumer mapping sort of technologies have done is provided geo-awareness to everybody. And they've done it principally by building a standardized basemap for the planet. And Google has been, obviously, the leader in this. But also, Microsoft is making a lot of contributions in the same space. And that allows me to navigate and understand a kind of electronic map or image so I can sort of see things. And that's pretty powerful actually for just spatial awareness and georeferencing people's minds about what's going on at different locations. In the last couple of years, I've seen a lot of VGI or volunteer geographic information added to it, little dots on maps. And that allows people to participate in these websites and share their knowledge in some kind of a collaborative space. And that's emerging quite nicely. []

London Street Atlas - Historical Edition




London Street Atlas - Historical cover imageLondon Street Atlas - Historical Edition

Geographers' Map Company was founded in 1936 by Phyllis Pearsall MBE (1906-1996) who, encouraged by her father Alexander Gross, took on the ambitious task of publishing up-to-date street mapping of London.

Mrs. Pearsall had the street map originals hand drawn on tracing paper using pen and ink whilst she compiled much of the information necessary to update the maps. This huge task involved her visiting the thirty one Borough Surveyors' departments concerned to obtain as much of their co-operation as possible. She also trudged the streets of London from dawn to dusk hand plotting the alignments of new streets and compiling ancillary information including house numbers along principle thoroughfares. Not least amongst her many tasks was that of the laborious job of card indexing the street names alphabetically in preparation for typesetting and this inspired the origin of the A to Z logo.

This online map of central London is made up from extracts of this mapping which Mrs. Pearsall published and can also be found in the Historical Edition of the A to Z London Street Atlas which can be purchased through this web site. This mapping, which includes bus, trolleybus and tram routes, shows the streets of London as they were just before the Second World War.

How Long Will the World’s Natural Resources Last?

Jeg kan slet ikke fatte hvor meget brændstof vi mennesker bruger og allerede har brugt ... 

I just can't grasp the amount of fuel being used ... how long will it last?



How Long Will the World’s Natural Resources Last?

This graphic from New Scientist shows when certain natural resources will run out in the world if we continue at the current consumption rate. However, reader beware, this graphic feels more like eye candy than real data. I'm no ecologist, but something about these numbers doesn't seem quite right. Completely out of gold in the entire world in 45 years? No more indium (for LCDs) in 13 years? I don't quite get the comparison between world consumption rate vs half of the US consumption rate. Why half? Again, I'm no ecologist, so maybe this is totally normal. I dunno. Maybe someone who knows better than me can chime in here.

Data assumptions aside, the design is interesting. A little scattered - but interesting. Can you think of some ways to make this graphic more informative?

Satellite Remote Sensing for Archaeology and more ...


Satellite Remote Sensing for Archaeology
This handbook is the first comprehensive overview of the field of satellite remote sensing for archaeology and how it can be applied to ongoing archaeological fieldwork projects across the globe. It provides a survey of the history and development of the field, connecting satellite remote sensing in archaeology to broader developments in remote sensing, archaeological method and theory, cultural resource management, and environmental studies. With a focus on practical uses of satellite remote sensing, Sarah H. Parcak evaluates satellite imagery types and remote sensing analysis techniques specific to the discovery, preservation, and management of archaeological sites. Case studies from Asia, Central America, and the Middle East are explored, including Xi’an, China; Angkor Wat, Cambodia and Egypt's floodplains. From Routledge, 2009.

Space Technologies for the Benefit of Human Society and Earth
When discussing the advancement of space science and space technology, most people instinctively think about deep space flights, lunar stations, and thrilling outer space adventures. The fact is that the majority of the human technology in space, which consists of interconnected satellites, points towards Earth, and is used to provide services for and fulfill the goals of people on planet Earth. Over the next decade, there will be an increased need for innovative Earth information systems to support the international space community's efforts to provide a robust infrastructure. This book describes some of the most important applications being developed, along with the space infrastructure upgrades being implemented to support them. From Springer, 2009.

Save and share directions with My Maps




You've probably been there: a friend asks you for directions to your house for a party, or to that nice picnic spot you recommended, so you try to scribble some lines on the back of a napkin or you try to explain out loud that they should take the second (or is it the third?) left. It's particularly a pain when you want to tell a bunch of people - like your entire housewarming guest list - directions. 

To make this easier -- for you, and for the people you're trying to direct! -- we've added features that let you save, annotate, and share directions using My Maps, the personal map editor built into Google Maps.

Saving driving directions to a My Map is easy: just click the "Save to My Maps" link below the directions in the left pane. 

This opens a dialogue box where you can choose to save to an existing map, or create a new one.
Once your directions are saved, you'll be taken into the My Maps editor, where you can edit the saved placemarks and route, as well as add new places and details to your map, like landmarks along the way.

We've also added a new tool that lets you draw lines along a road to get from point to point. This is accessed via a drop-down menu in the line tool by clicking and holding briefly anywhere on the button.

The tool calculates the best driving route between your line's vertices and automatically snaps your line to the appropriate road. 

With your directions saved in My Maps, it's easy to add notes, share with friends, embed in web sites, and invite collaborators to contribute to your map. 

So when it comes time to plan your next road trip, consider using My Maps as your planning tool -- at the very least, if you hit a bump and spill coffee on your map halfway through the trip, you'll still have a backup.
