Technology Review:
The latest technology developments in exploration data management
Exploration and Production (E&P) industries are experiencing unprecedented growth. There are a record number of projects being explored and developed, and projects are expanding to include more surveys and drills than ever before. Here are some of the latest technology innovations in geospatial data management that are helping exploration companies manage their growth and their opportunities.
Building a strong foundation.
Building your data and knowledge foundation begins in the field,
with data collection, and includes everything from data organization,
consolidation and archiving to metadata management. Beyond data
management, a strong foundation ensures that your data is reliable
and ready for delivery to all the people that need it, within your
team, or global organization.
Geosoft DAP data cataloguing and server technology has matured to
support every stage of building your foundation.
Data Catalogue. Geosoft
DAP establishes a catalgue of all your available spatial and earth
data resources. This includes data stored on organized file systems
in the many common formats (grids, images, raw data, and file documents),
metadata stored in RDBMS systems, spatial data stored in certain
RDBMS systems (such as acQuire and ArcSDE), and data stored within
corporate archiving systems.
Metadata Management. DAP’s
Metadata Editor Tools allow you to modify and maintain your metadata
schema. You can integrate your own existing corporate Metadata models
and databases into your Foundation. Or you can use one of the three
metadata models available through our Global Solutions Group. The
Metadata Editor Tools are easy to use and support both Users and
Administrators. Users have the ability to enter Metadata and submit
the data with metadata to the Data Administrator. Administrators
can also enter Metadata, and have the tools to review submitted
data and metadata, for upload to the DAP Server and Metadata database.
Secure Data Access. Increased
exploration activity has resulted in a need to access and share
data within your organisation and with external partners and consultants.
To maintain control and security of your data foundation Geosoft
has implemented a DAP security model by integrating with Microsoft
Active Directory. This allows organizations to maintain users and
groups in Active directory, and the DAP Data Administrator will
be able to assign rights and privileges to DAP data based on these
users and groups.
Scalability across your enterprise.
Your exploration data management solution needs to be scalable across
your enterprise, whether you need to implement a single server solution
for a defined group of users or to deploy a company-wide strategy
serving many users at multiple locations worldwide via an Intranet
and the Internet. The scalability of Geosoft DAP technology has
been proven over eight years of successful deployment within global
exploration organizations. DAP server technology can catalog and
maintain several hundred thousand data sets. Geosoft HyperStore
allows administrators to publish certain performance-sensitive data
as a "hyper-store", which is optimized to support high-performance
windowing and extraction for very large datasets. A good example
is the 60,000,000,000 points global SRTM topography data stored
as a hyper-grid that users can access remarkably fast.
Improved data access. Important
to the success of any data management strategy is your ability to
provide seamless access to your data foundation. Geosoft DAP enables
efficient search and evaluation of your data for project needs and
opportunity development. DAP was designed to make finding data fast
and easy. You can search for data by area of interest, data type,
and full metadata evaluation to determine the value of each dataset
for a particular use. Before downloading your selected datasets,
you can quickly preview the content to make sure it’s what
you need. Users can retrieve your data from anywhere in the world,
and share it. Data retrieved from your DAP servers can be windowed
to the area of interest, re-projected to an appropriate coordinate
system, sampled to an appropriate scale, and instantly transformed
into your application. This includes simple retrieval of documents
and reports that support the data, which can be viewed in their
native formats such as .doc and .pdf files.
Support of 3D sub-surface datasets.
As the use of subsurface 3D data continues to expand within exploration,
so does the need to archive and support it within your organization.
With the latest release, Geosoft DAP now supports the cataloging,
discovery, and delivery of Geosoft voxel data along with all the
standard exploration data types. For cataloging, DAP will find and
visualize 3D Geosoft voxel files and extract metadata for data discovery
purposes. Voxel data will then be visible in a spatial context to
DAP clients. Clients will be able to resample voxel data to meet
their needs and extract the data to their application. The windowing/sampling/extraction
process includes re-projection of the 2D coordinate system to the
client context and high-performance streaming of the data to the
client.
Geosoft Voxel data clients include Oasis Montaj and Target for
data discovery, simple 2D visualization and file download. The DAP
high-performance compression and streaming technology on the network
will make voxel retrieval practical even for relatively low-bandwidth
connections (such as office-to-office).
Integration with Globe Viewers. Geosoft’s Dapple globe viewer is an open source alternative
to Google Earth that combines Google’s usability with more
advanced workflow for exploring large, earth data. Dapple provides
geoscientists with a better way to work with the hundreds of online
WMS server sites that provide useful images of geospatial data.
Dapple support of Geosoft server technology, DAP, delivers a whole
new value to Geosoft Global Solution customers, enabling them to
search, find, and see data from their own massive data resources,
as well as public sources in one viewing environment.
The Benefits of Metadata Management
In order to establish data management best practices, it is important to set a standard for handling of metadata by employing a comprehensive enterprise metadata management system that includes xml support for offline metadata. Through your metadata management system you ensure:
- Support of internal corporate standards, business rules and
protocols to enforce the preparation of metadata for exploration
data files.
- Metadata is secured by the integrated security mechanism of
the Microsoft SQL Server. Users can only see and/or edit what
they are allowed.
- The metadata entry tools allow multiple users to enter metadata
into a metadata database at the same time.
- Exploration data and metadata, saves as xml, can be shared easily,
internally between offices and externally with venture partners.

Metadata Editor supports standard
for handling of metadata. New Geosoft Metadata Editor Tools allow you to modify and maintain
your metadata schema. You can integrate your own existing corporate
Metadata models and databases into your data foundation. Or you
can use one of the three metadata models available through our Global
Solutions Group. Metadata Editor Tools are easy to use and support
both Users and Administrators. Users have the ability to enter Metadata
and submit the data with metadata to the Data Administrator. Administrators
can also enter Metadata, and have the tools to review submitted
data and metadata, for upload to the DAP Server and Metadata database.
The xml files created by the Geosoft Metadata entry tool are designed
to be compliant with FGDC and ISO19115 metadata standards.
Metadata Templates. Supplementary metadata can be catalogued using supplementary metadata
templates. Metadata templates refer to the structure of the relational
database that store the supplementary metadata, DAP dataset directory
structure, and the link between the two. With the Metadata User
version, geoscientists who submit the survey data will be able to
enter the metadata and save it as xml files. They can then submit
the original survey data and the metadata to the Data Administrator(s)
for cataloguing and publishing. The Data Administrator(s) can then
use the Admin Version of the tool to load the metadata in the xml
files into the metadata database. This practice is expected to save
valuable time that can be better spent on gathering the metadata
for the datasets to be published.
