OpenEarthTools tutorials available in matlab help browser
All Matlab tutorials that are on this wiki and in the repository are now also available through the matlab help navigator.
Command line help support for tutorials
In addition to that a Contents.m file is automatically created for the tutorials dir.
Try for example:
help tutorials
It will give you an overview (including links) to the tutorials available in OpenEarthTools. If you click on one of those links it will automatically open the help browser at the specified tutorial.
Other content of the matlab toolbox item in the help browser
Besides the tutorials the table of contents of the OpenEarth toolbox also contains links to most relevant pages on the wiki.
Search tutorials through matlab help navigator
Starting at Matlab version 7.4 (2007a) it is also possible to include a search database in the matlab help. This database is matlab version dependant and will therefore automatically created in oetsettings. It is therefore also possible to enter keywords in the search box of the matlab help navigator or search in the tutorials command line:
Try for example:
docsearch OpenEarth
There is now a general page called: "ContentHeader". Including this page in the first line of a new page automatically includes all items in the ContentHeader page to the top of your new page:
{include:ContentHeader}
In this way it is possible to automatically adjust all headers by editing only one page (ContentHeader)
The high-frequency Markermeer timeseries data gathered by Bas Blok (Deltares) on behalf of Rijkswaterstaat have been added to OpenEarth.
The data consists of timeseries of - amongst other - temperature, turbidity, wave heigth, velocities, water level and velocities at locations FL41(52'28.6307N,5'07.7513E) and FL42(52'31.962N,5'13.956E).
All raw data + reports are archived the OpenEarth repository:
https://repos.deltares.nl/repos/OpenEarthRawData/trunk/rijkswaterstaat/IJG/
Some data have been transformed into netCDF for ready plotting in for instance ncBrowse:

Last year, in the framework of the Deltares-USGS cooperation agreement, a study was performed to demonstrate the applicability of UCIT (a matlab based graphical user interface for coastal analysis) to store, manage, analyze, and access all the information related to the derivation of shorelines from lidar data as part of the USGS national shoreline change project. Recently, it was decided to make all UCIT scripts and data part of OpenEarth.
This year a follow-up sprintsession was held from September 29th to October 1st, 2009, at the Woodshole office of USGS. The main purpose was to add extra data and functionality to UCIT / OpenEarth and to train the USGS staff to use UCIT / OpenEarth.
UCIT currently enables quick browsing through a huge number of US LIDAR transects (as well as Dutch JARKUS transects) and performing various analyses. The next planned step in the Deltares-USGS cooperation agreement is to perform a shoreline analysis along the North Carolina coast.
Data sharing, archiving and reuse is an increasingly hot topic also discussed in recent scientific reports and publications.
Nature has devoted a special to the topic recently: http://www.nature.com/news/specials/datasharing/index.html
And AGU's EOS refers to it as well in this article: http://public.deltares.nl/download/attachments/28191266/2009EO350008.pdf.
The tutorial page is now structured with a division between tutorials concerning OpenEarth in general, Data, wiki tutorials and tutorials on the use of the OpenEarthTools.
Tutorials on the use of OpenEarthTools are directly retrieved from the OpenEarthTools repository. Just commit any change to an existing tutorial or create a new one and regenerate the tutorial overview and it will be visible on the wiki pages. A tutorial (of course...) on how to make tutorials is being created at this moment and will be available soon.

OpenEarth is pleased to announce a visit to Alkyon. A lunchlecture is planned in the Geomatics Business Park on november 11th 1.
1rescheduled from earlier plans.
OpenEarth was pleased to be have the opportunity to introduce itself at an NODC board meeting. OpenEarth introduced its aims (an open source approach for sharing data, models and tools) as well as its technical infrastructure (Subversion repositories, collection of netCDF datafiles on an OPeNDAP server).
On Aug 25th OpenEarth presented a Deltares wide lunchlecture "Visualizing our Delta in Google EarthTM" for an overcrowded theatre. Thijs Damsma gave an impressive live demonstration with Google Earth TM of the new GooglePlot toolbox in OpenEarthTools. The entire 20 GB Dutch 'vaklodingen' coastal bathymetry dataset of Rijkswaterstaat could be inspected as a whole for all available years since the 30s (google earth overview, data). This was made possible by the new tiled image tool in OpenEarthTools. Currently the same tiled image is being prepared for the Dutch 'Jarkus' beach/dune bathymetry dataset (google earth overview, data). Both sets will become available on OpenEarth servers soon. After the lunchlecure a dedicated afternoon sprintsession was organized for the Matlab enthousiasts who wanted to use the GooglePlot toolbox from OpenEarthTools too. Presentation of geophysical data on virtual globes becomes increasingly more popular among scientists and engineers, e.g. Virtual globes at AGU.

An Introductory Wiki Training Course tutorial was added to list of OpenEarth tutorials. This self explanatory tutorial explains how to best use the Confluence wiki system. More information can be found at General OpenEarth documentation.
A number of tutorials have been added to Matlab Tools Basic Course. These self explanatory tutorials discuss a number of handy tools that are available in the OpenEarth toolbox. More information can be found at General OpenEarth documentation.
M.Sc. Thesis Presentation
Dune growth on natural and nourished beaches:
'A new perspective'
Dune evolution on natural and nourished beaches on an engineering timescale is not well understood. Using a study of both literature, and data which has been gathered of the Dutch coast, a new hypothesis regarding the causes of variability in dune evolution is proposed.
Following this hypothesis assumptions are made on the basis of which a conceptual model is developed that includes both the accretive and erosive processes that govern dune evolution.
