Feedback: What Customers Liked about 7.3
New
Inverse Distance Weighted gridding
This Inverse Distance Weighted gridding example shows a comparison of inverse distance weighted gridding to minimum curvature and kriging.

Darrell Hall, Principal Geophysicist with URS Corporation, was happy to see the addition of inverse distance weighting (IDW), the new gridding algorithm available in Oasis montaj.

"I really like the improvements, in Oasis montaj 7.3, including IDW gridding," said Darrell. "I've harped enough times about it, now that it's been added I just wanted to say thank you, it looks like a very good implementation. It feels like Geosoft did it just for me! "

Knowledge
Specialist
A searchable support Knowledge Base is now available on geosoft.com. It can be accessed within the Support Centre, from the main support menu or the support page for each Geosoft application.

Using the Support Knowledge BaseAs an example, on the Oasis montaj support page shown here, Knowledge Base is the last tab on the right. By searching from a product page, only articles related to that application will be displayed.

The Knowledge Base is also available from the Support menu visible on any Geosoft web page.

There are 4 knowledge base article types:

  • How To – These articles outline the use of a tool, or a series of tools to achieve a specific task.
  • Troubleshooting – These articles describe a specific problem that is encountered due to a misuse of a tool or they describe a problem with the tool itself. Resolution steps describe proper use of the tool or a work around if there is a known issue with a function.
  • Error Messages – These articles will state the exact error message that is encountered and the possible steps to resolve the problem. The cause of the error message will also be listed if it is known.
  • General Information – These articles contain information not directly related to completing a task. They may include material on theory, policy, compatibility, etc.

After you type in your keywords and click Search, the Article Type tabs will show how many articles have your keywords in them. For example, if you type in a few keywords from an error dialog that was displayed when attempting to run a function, you will need to click the Error Messages tab to see the relevant articles.

For each article, there is a Submit Feedback button at the bottom. You must be signed in with your Geosoft ID in order to send us feedback on an article. You can find more information on Geosoft ID here if you have not registered yet.

Know How: Introduction of How-To Guides
Know how
How-To GuidesGeosoft has introduced a new type of help resource – How-To Guides. These guides provide instruction on how to accomplish a particular workflow using a Geosoft product or extension.

How-To Guides include detailed procedural instructions and screenshots to show the results expected from specific actions. There is no reliance on any particular dataset, allowing you greater flexibility in learning with the data you have available.

We are working towards having How-To Guides for all workflows available in Geosoft's suite of software products. Here's a list of the How-To Guides currently available:

3D Voxel Utilities and Conversions
With the recent addition of new 3D utilities and conversion options, we have posted How-To Guides that provide context, and walk you through the procedures for these new features.

CET Grid and Porphyry Analysis
We have created a set of comprehensive How-To Guides to help execute the more common workflows in the powerful CET image analysis extensions.

Induced Polarization
For users of the montaj Induced Polarization extension, Geosoft has developed a How-To Guide that assists in importing and displaying 3D IP Data.

We will continue to provide more How-To guides in the coming months, beginning with guides for new Gridding Methods that were introduced in the June 2011 release.

You'll find all available How-To guides in the Downloads Centre, under Technical Documentation.

Ideas: Best Practices for Handling the Data Explosion
Ideas
First there were megabytes, then gigabytes, and now terabytes, and petabytes. Just one petabyte is the data equivalent of a stack of DVDs from here to the moon, and they're coming to an exploration office near you. Natalie Green, Geosoft Technical Product Manager, has compiled five best practices to make exploration data management more efficent.

Where to start?

  • Clear the clutter. Identify which applications and formats are essential for your business and cull the rest.
  • Find your coordinates. Ensure geographic coordinates are accurately recorded in the field, and managed as part of the data.
  • Use classifications. Using classifications, such as continent, country, state/region, project name, data type, to organize the data makes the discovery of data more efficient.
  • Add descriptors. Establish and maintain a standard set of minimum required metadata fields for every dataset.
  • Make it flow. Streamline your workflows to move the data through the system from collection to collaboration and ensure that all users know where to find existing data and put new data.

Success: Clearing the Way for the Winds of Change
Success
According to the European Wind Energy Association, 308 new offshore wind turbines generating 883 MW in eight new wind farms were connected to European national grids in 2010 – a 51% increase over 2009. It was a new record that brought the region's offshore power to 1,136 connected turbines; totaling 2,946 MW in 45 wind farms throughout nine countries. There's great potential to go even further: "Europe's offshore wind potential is enormous and able to power Europe seven times over," states the EWEA.

The rush has spawned a boom in UXO seabed surveys. They are critically important: according to a story in the August 2010 issue of Offshore Wind Engineering, experts estimate that ten percent of military ordnance deployed during the Second World War failed to detonate. Still-live naval mines and air-delivered iron bombs present the greatest danger. This seabed contamination includes residue from defensive barrage minefields not fully cleared at war's end, torpedoes, land to sea artillery, dumped munitions and shipwrecks. In the English Channel alone, UXO dangers lurk along the coastline as far north as the Humber, Tyne, and Tay estuaries – all key wind farm sites.

Product News: CET Porphyry Detection
New
CET Porphyry DetectionThe new image analysis extension, CET Porphyry Detection, is the latest innovation to come out of Geosoft's collaboration with the University of Western Australia's Centre for Exploration Targeting.

This Oasis montaj plus extension was specifically designed to detect magnetic porphyry signatures. It provides a methodology for the detection of roughly circular porphyry features, with options to specify the target size (or size range) of porphyries and a constraint on expected circularity of target porphyries.
