Geosoft DAP Server Technology

Geosoft DAP Server fits into a service-oriented architecture (SOA) and provides services to catalog, manage, deliver and visualize large, spatial earth data.

Cataloguing

Geosoft DAP server can catalog and maintain several hundred thousand data sets within a managed environment. Geosoft DAP can catalog data stored on organized file systems in many common formats (grids, images, raw data, and file documents), spatial data stored in ESRI environments and RDBMS systems such as acQuire, and data stored within corporate archiving systems.

Geosoft DAP also supports the management of metadata created in Oasis Montaj, Target, Arc Catalogue, and related applications.

Publishing

Data is published through Geosoft DAP via a file system and can be organized in a way that makes sense to the data publisher. Publishing services include metadata viewing, graphical data viewing, data extraction and data catalog queries. Data extraction provides for transfer of all or windowed parts of the data at an optimal resolution, in any format and in any coordinate system.

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.

Search and Discovery

Geosoft DAP enables efficient search and discovery of data, regardless of source. You can search for data by area of interest, data type, and Subject of Interest through the interrogation of metadata, 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.

Data Delivery

Geosoft DAP server utilizes TASK streaming technology to efficiently deliver large, geospatial data sets. It provides the ability to extract, window, translate, compress and stream data to multiple clients.

While repository technologies typically require high-bandwidth access to the data stores, Geosoft DAP's compression and streaming uses standard HTTP to enable data access over low-bandwidth connections. It provides encryption and Active Directory support for secure data transfer and permissions that enable further security.

Metadata Management

Geosoft DAP metadata management includes support for FGDC and ISO19139 metadata standards, together with the introduction of Geosoft metadata schema. The management functions includes the graphical viewing of metadata by use of style sheets in Oasis montaj and DAP Administrator and the cataloguing of metadata in XML files and synchronization of metadata in relational databases and XML files.

Software Connectivity

As a middleware server technology, Geosoft DAP connects disparate data storage and management systems, and creates value by handling tasks like data cataloguing, managing and maintaining metadata to support effective and standards based user access to data. Geosoft provides integration solutions for leading data storage applications, such as acQuire and can manage point data stored in other Relational Database Management systems.

Geosoft DAP also integrates with ESRI ArcGIS Server to support the cataloguing and publishing of spatial data stored within ESRI environments. These new capabilities include being able to catalogue and publish ESRI LYR files, ESRI file GeoDatabases, ArcGIS Server Map Services, ArcIMS Image Services and ArcIMS Metadata Services.

Web Client and Application Support

Geosoft DAP supports any web client application, such as an ArcIMS client through Geosoft XML, or a MapServer application through OGC compliant WMS and Geosoft XML. The "thick" clients such as Oasis montaj, ArcGIS, and MapInfo can be supported through free plug-ins that uses the high performance TASK protocol. Almost any data retrieval experience can be created through a .NET development that takes advantage of the Geosoft open GX Developer environment.

Data Support

Geosoft DAP server is able to efficiently catalog and deliver a broad range of data file types, including very large geospatial grids, 3D voxels, images and vector data. View full list of supported data types.

Security and Administration

Geosoft DAP Administrator provides a comprehensive toolset for Data Managers to administer DAP servers and manage DAP data catalogs. Security features include support for Microsoft Active Directory. All data can be secured on a user or group level. Security can also be established on a file-by-file basis.
