Data Discovery

Data stored in the NDR is grouped by Project IDs.  The Data Discovery section will assist you in finding data most relevant to your requirements.  To access this section, select the Data Discovery tab from the NDR homepage.

 

 

To use the Data Discovery function, two approaches can be taken.  An Overview Map can be used to spatially identify the data of interest, or alternatively, the Project ID window can be used to filter on the various metadata to locate the required material.

 

All data within the NDR is assigned to a unique Project ID, which is used to group and assign a spatial location to related data.  The Project ID is made up of four parts following the pattern CCCCYYYYtypeNNNN –

 

CCCC - An ID that denotes the original company that completed the project. This is not necessarily the current owner of the Project ID.  It takes the form of a 4-character alphanumeric code representing the company (see company code list), for 2-character companies append trailing underscores to make it 4 characters, e.g., BP__ or TT__

 

YYYY - The year, e.g., 2020, that the project took place in. For example, the year the data was (re)-processed. A 4-character numeric year in which the project was performed (if between years, choose the earliest), this is not the acquisition year of the input datasets.

 

type -  The type of project, either: Wellbore (well), Seismic Survey (seis), Site Survey (mhaz), Remote Sensing (rems), or Interpretation (intp).

 

NNNN - Automatically assigned increment starting from 0001.

 

Each Project ID is supplemented with metadata to help you discover Project IDs that are most relevant to you. The Project ID will also have a current owner assigned to it and this can change over time. A Project ID is subject to release rules and a given Project ID can either be released or kept confidential to a particular company or companies. Released Project IDs are discoverable by all NDR users, whereas confidential Project IDs are only discoverable by an entitlee.

Project ID will be assigned before data is uploaded to the NDR and is required to be selected on the upload form.  Project ID is not the same as a NDR9 survey name or NSTA wellbore name.

 

Within the Data Discovery section of the NDR portal, 3 windows are present …

• Overview Map (with Map Layers)
• Project ID Table
• Files Table

 

Overview Map

The map can be utilised for spatial searches there is a separate support document here.

Project IDs Table

 

The Project IDs Table lists all the disclosed projects and their associated files in the NDR. By default, all projects loaded to the NDR are displayed. This table can be filtered on a number of parameters which can be selected in the search field at the top of each column.

 

 

 

Within the Project IDs Table display, you have the option to show only selected Projects by clicking on the ‘Show Selected’ tab after ticking the Project IDs of interest in the left-hand column.

 

 

 

By clicking the "Show All" tab you are returned the the original view.

 

When the data required has been identified, the datasets are selected by checking the box on the left-hand table.  The files associated with that particular Project ID can be viewed in the File Table window below by clicking the ‘View Files’ tab.  The number in the File Count column tells you how many associated files there are with the project.

 

 

You can create a CSV export of the selected Project ID files by clicking the Export CSV button.

 

When hovering the cursor over the listed Project IDs, the location of the project area is highlighted in the Overview Map display.

 

 

Project IDs can be grouped by the metadata domains listed at the top of the table, for example, grouped by Seismic Type domain would create 8 rows with projects gathered into project types 2D, 3D, 3D Merge, OBS, Site, 4D, undefined and "0". Clicking on the Expand/Collapse tab will alternate the view of these files as sorted.  

 

You have the ability to group on any of these headers by clicking on the black arrow to the right of the header name.

 

Below each category, there is a filter box. If you start typing here, the Project Table starts filtering. In the example below, filtering has been done on the "Owner", as can be seen, this filtering is not case-sensitive, and you do not need the full name.

 

 

Several of the filter boxes have drop-down menus as opposed to free text, these are indicated by "multi" and an arrow. Click on the arrow and filters can be seen. For example what type of project

 

 

The grouping can be collapsed or expanded by selecting the ‘Collapse Groups’ tab in the top right side of the Project ID window. Clearing groupings and filters can also be done with the corresponding buttons.

 

 

 

You can hide or display both reported and unreported data by clicking on Project ID down arrow and selecting "show both (Un)reported"

 

Unreported data has a file count of "0".

 

Files Table

 

The File Table appears below the Project ID Table and Overview Map windows.

 

 

Files listed here represent those associated with the Project ID selected in the table above.  

Files can be previewed by selecting the preview tab.  

This allows you to visualise the data or report prior to requesting the download.  A report, for example, will preview online the first 5 pages to allow a user to determine whether the quality and contents are suitable for their requirements. Certain file types can not be previewed for example "LIS" files

 

When the files have been reviewed, selection can be confirmed with the ‘Add Files to Session Basket’ tab as required.  

 

When the selection is made, the number of files selected is shown in the ‘Session Basket’ tab at the top of the page. On completion of data selection, you can then create a download package or request on physical media.
