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:

Matlab
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:

Matlab
docsearch OpenEarth
Unable to render {include} The included page could not be found.

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:

Confluence wiki
{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:

OpenEarth - USGS joins OpenEarth

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.
