ArcGIS extension - Geochemistry.... What is Geochemistry for ArcGIS ???

Ekstensi Geochemistry untuk ArcGIS .....

Talking about ArcGIS is very interesting.., let's find out...

Berbicara tentang ArcGIS sangatlah menarik...

GIS talk On Friday, April 17, 2009 informs us

Geochemistry for ArcGIS extension

Geosoft Inc. has announced the commercial availability of their Geochemistry for ArcGIS extension for ESRI's ArcGIS software. The Geochemistry for ArcGIS extension adds a geochemical workflow to ArcGIS, enabling geoscientists to efficiently conduct their geochemical QA and analysis inside ESRI.

Geosoft Announces Geochemistry Extension for ESRI ArcGIS

Geosoft Announces Geochemistry Extension for ESRI ArcGIS Extended capabilities enable multivariate geochemical analysis inside ESRI

TORONTO, April 16, 2009 - Geosoft Inc., a world leader in software and solutions for earth exploration, announced today the commercial availability of their Geochemistry for ArcGIST extension for ESRI’s ArcGIS software. The Geochemistry for ArcGIS extension adds a powerful geochemical workflow to ArcGIS, enabling geoscientists to efficiently conduct their geochemical QA and analysis inside ESRI.

...........................................................

“Geosoft’s Geochemistry extension further extends the explorer’s toolkit, by providing the ability to analyse geochemical data within the ArcGIS environment,” said Louis Racic, Director of Product Management. “It builds on the success of our subsurface geology extension, Target for ArcGIS, and provides a powerful exploration workflow solution not currently available in the market.”

Argo Float - akses data

Apa itu Argo Float, bagaimana ceritanya, dimana persebarannya, untuk apa ya ???

Munculnya Argo Float merupakan sebuah konsep revolusioner dalam sistem observasi kelautan dan metode pengukuran global. Argo Float merupakan instrumen yang bergerak mengikuti arus bawah laut yang disebar di lautan terbuka dengan resolusi spasial kira-kira 300 km. Selama satu kali dalam sepuluh hari akan muncul ke permukaan di akhir tiap siklusnya dan mengirimkan data ke satelit komunikasi (misalnya: satelit ARGOS)

Argo Float - silahkan akses data Argo Float...bisa dilihat Argo yang telah matidan yang masih hidup di http://www.marine.csiro.au/~gronell/ArgoRT/select_floats_WMO.html

Untuk akses data Argo kini cukup mudah..dan enak dilihat euy..karena memanfaatkan google earth..

What is Argo? Argo is a global array of 3,000 free-drifting profiling floats that measures the temperature and salinity of the upper 2000 m of the ocean. This allows, for the first time, continuous monitoring of the temperature, salinity, and velocity of the upper ocean, with all data being relayed and made publicly available within hours after collection.

Positions of the floats that have delivered data within the last 30 days (AIC, updated daily):

Why do we need Argo? We are increasingly concerned about global change and its regional impacts. Sea level is rising at an accelerating rate of 3 mm/year, Arctic sea ice cover is shrinking and high latitude areas are warming rapidly. Extreme weather events cause loss of life and enormous burdens on the insurance industry. Globally, 8 of the 10 warmest years since 1860, when instrumental records began, were in the past decade. more information...

Where is Argo now?

Argo deployments began in 2000 and by November 2007 the array is 100% complete. Today's tally of floats is shown in the figure above. While the Argo array is currently complete at 3000 floats, to be maintained at that level, national commitments need to provide about 800 floats per year (which has occurred for the past three years). more information...

Who Collaborates with Argo?

Argo is a major contributor to the WCRP's Climate Variability and Predictability Experiment (CLIVAR) project and to the Global Ocean Data Assimilation Experiment (GODAE). The Argo array is part of the Global Climate Observing System/Global Ocean Observing System GCOS/ GOOS).

Pada 19 Maret 2009, saya menerima email dari
Dr Tseviet Tchen
CSIRO Marine and Atmospheric Research

mengatakan bahwa ada info baru di blognya Argo... :

" Regarding Argo, there is a new thread to its blog about the Argo outreach effort, to which you may want to contribute. "

Argo outreach resource

In line with the Argo outreach effort, CSIRO has been hosting a web-page which provides weekly updated T/S profiles for the global Argo array:

http://www.marine.csiro.au/~ttchen/argo/gmap.htm, with specific characteristics as follow:

* national grouping for floats localisation
* low-cost hardware requirements for web-access, ie access is via GoogleMap which requires no high-speed graphic card, in contrast to Google Earth.

Usage: hovering the mouse-pointer over the icon of a float brings up a menu which lists clickable links leading to float information, such as TS-plots.

More detailed real-time data are available for the Australian floats at http://www.marine.csiro.au/~gronell/ArgoRT/select_floats_WMO.html

You are most welcome to explore this resource and to feedback any comments.

Tseviet Tchen.

SeaDAS for Windows XP and Vista

SeaDAS Virtual Appliance
released for Windows!
SeaDAS VA 5.3b (beta) allows SeaDAS to be run on Microsoft Windows XP and Vista systems within a virtual Linux machine.
This is a fully functional version of SeaDAS and processing benchmarks show very impressive performance.

SeaDAS VA is simple to install and requires the free VMware Player.

SeaDAS - Level-2 processing MODIS

What is SeaDAS

The SeaWiFS Data Analysis System (SeaDAS) is a comprehensive image analysis package for the processing, display, analysis, and quality control of ocean color data.

Supported satellite sensors are
MODIS, SeaWiFS, OCTS, and CZCS.

SeaDAS Primary Functionalities

Processing programs:

*SeaWiFS:*	L1A, L1B, L2, L3, and SMI (Standard Mapped Image) processing Map projection of L1, L2, and L3 files L1 and L2 Browse product generation L1A to L0 program for renavigation Interactive L1 coastline registration and L2 QC L1 subscene extraction
*MODIS:*	L0 to L1A Direct Broadcast processing L1A Geolocation processing L1A subscene extraction L1A to L1B processing L1B to L2 processing L2 and L3 binning SMI processing Map projection of L2 and L3 files
*CZCS:*	L1A to L1B processing L1 to L2 processing L2 and L3 binning SMI processing

l2gen

Description: This program performs Level-2 processing on MODIS, SeaWiFS, OCTS, or CZCS data and generates Level-2 geophysical products by applying atmospheric corrections and bio-optical algorithms to the sensor data. The input data levels required for l2gen processing are as follows:

MODIS: input must be an Aqua or Terra L1B file
SeaWiFS: input may be either an L1A or L1B file
OCTS: input must be either a NASDA-format L1B file or SIMBIOS-format L1B file
CZCS: input must be a CZCS L1B file
