About this Release

With the release of DAP 11, Geosoft has focused upon enhancing and broadening the user experience while adding more capabilities so that companies can fulfil their Exploration Data Management Strategies.

Leveraging ArcGIS Server technology within this release has allowed for greater support for ESRI Geographical Information, beyond traditional integration with Shapefiles. Enhancements to our Metadata Management Solution broaden our ability to support the most up to date industry standards while extending our use of customizable stylesheets.

On top of these changes, we have also made general enhancements to the DAP Cataloguing Process and DAP Administration. These changes will improve performance of the DAP server administration and make the process of managing large Exploration Data sets easier and efficient.

Greater Integration with ESRI Environments

With this new release, Geosoft is licensing and embedding ESRI technology to further the integration of the DAP server tools with ESRI Environments. Integration through ESRI LYR files allows us now to integrate DAP cataloguing and publishing services extending the number and types of ESRI data sets the DAP Server technology can manage. This integration can greatly promote and enhance the workflow that geoscientists use in their exploration projects.

With DAP 11 we are also introducing a new and important utility to manage ESRI data. The Geosoft LYR File Packager is a utility tool used to assemble the vector and raster image data that a MXD or LYR file points to. It imports the data into an ESRI file geodatabase and bundles the new file geodatabase and LYR file(s) into a single zip file. This facilities the management of ESRI data as distinct data subsets, allowing end users and Data administrators to publish only the data that they wish others in their organization to see, without having to publish whole ESRI data environments. The LYR File Packager is also built into the Geosoft Metadata Editor, which uses the functionality to create a data package for submission from a LYR file.

With these new capabilities we have extended our ESRI Support to include the management of:

  • ESRI LYR files
  • ESRI file GeoDatabases and ArcSDE
  • ArcGIS Server Map Services
  • ArcIMS Image Services
  • ArcIMS Metadata Services
  • ESRI Shape files (SHP) and ESRI Smart Data Compression (SDC)

For a complete listing of the GIS data types now managed by the DAP Server technology, please refer to Supported Data Formats.

Geosoft Metadata Solution Supports Natural Dataflow

Metadata is data that describes data. Geosoft integrated metadata solution is flexible and configurable, and supports FGDC and ISO 19139 metadata standards. It can also be expanded to support the metadata and terminology that is unique to the individual customer.

Also with the release of Oasis montaj 7.0.x and DAP 11, Geosoft introduces a fully integrated metadata solution from metadata creation to publishing. The overall goal of this solution is to create a natural metadata flow from data creator to data publisher.

The Geosoft metadata solution includes:

  • A Geosoft metadata schema and support for FGDC and ISO 19139 metadata standards
  • Cataloguing of metadata in XML files and synchronization of metadata in relational databases and XML files
  • Supports the new DAP Server data types such as ESRI LYR files
  • Graphical viewing of metadata is enhanced with the use of XSLT stylesheets in Oasis montaj, DAP Administrator and DAP client interface
  • Graphical Metadata Editor supporting both User (online and offline) and Admin modes

General Enhancements in DAP Server and DAP Administrator:

Beyond ESRI integration and a greatly enhanced metadata management solution, Geosoft has made a range of changes to improve Data Administration and overall performance. Several changes have been made to improve the Data Administrator function:

Distributed Cataloguing Service (DCS)

Through the re-architecting of the cataloguing process, Data Administrators are now able to utilize multiple computers to perform the Cataloguing process. This ability to distribute cataloguing across multiple computers greatly improves performance.

Setting of coordinate system and extent to datasets in a folder

This capability provides functionality to assign a coordinate system, and optionally extents, to datasets residing in a selected folder. It is designed as a batch tool to prepare document datasets, common raster images and occasionally grid files.

Support of disclaimer/copyright at dataset level

This highly requested capability enables companies (data publishers) to set the conditions of downloading and using the data.

The ability to turn on/off Auto cataloguing of datasets in DAP data folders

This capability will especially benefit smaller companies who may not have a dedicated data administrator to catalog new and updated datasets. In this way, data administrators can set a "watch" to specific folders that have been cataloged. When the content of the folder changes as a result of a dataset update or addition of a new dataset, the DAP Administrator will re-catalogue, on a timed basis, the datasets in the folder in the background using DAP Administrator scripts.

RDBMS Data Connector

The RDBMS Data Connector catalogs and publishes point data in relational databases using ODBC DSN connections. The use of DSN connections allows publishing of point data in virtually any relational database.

Section grids and images

DAP 11 introduces the ability to catalog oriented grids and raster images (section grids/images). A section grid maybe a grid (GRD) or image (TIF, JPG, etc).

Refresh catalogue components

DAP cataloging or recataloging datasets is a time consuming and process intensive process. In DAP 10 or previous versions, a dataset needed to be re-catalogued when the security setting or metadata linked to the dataset was modified. To improve the cataloging performance, the cataloging process in DAP Administrator has been redesigned during the v11 release cycle. New and separate menu commands are now available to perform some of the tasks that used to be part of the cataloging process in previous versions.
