Dataset Options

Datasets can be filtered by sector group, condition expression, event set, and/or user-defined region. Those filters will affect what data is to be considered for data

presentation and statistics. In addition, TEMS Discovery can list only the files that meet the listing filters, problem set, favorite flag, or collection date/processing date. You can also search the dataset tree for any label that contains the search text.

4.1.1.3.1 On-fly Composite

The On-fly Composite option allows the user to create dynamical composite dataset based on multiple device attribute. This option is only available when database is selected for measurement data storage.

4.1.1.3.2 Data Filters

The Data Filters option is different from the Listing Filters (Non-Composite) option. The Data Filters option will not affect the dataset listing in the Data Explorer, but it will affect what data can be analyzed and displayed. In another words, if a metric is dragged-and-dropped to any view, only the data within the filtering region covered by the sector group and meeting the conditions will be displayed.

 Sector group. If a sector group is selected, only the data at the location that is covered by the sectors in the sector group will be considered. See Cells in Map View for information about defining a sector group.

 Condition. If one or multiple condition expressions are selected, the data to be considered must also meet the condition. Click the Browse button to open the Script Builder, where you can define or edit a condition expression. See the Script Builder section for more information.

 Event set. If an event set is selected, the data to be considered must also meet the condition defined in the event set. Click the Browse button to open the Event Set Configuration dialog, where you can define or edit an event set. See Event Set Filter for more information.

 Region. If a filter region is selected, only the data within the defined region will be considered. See GIS in Map View for information about creating a user-defined region (UDR) and assigning attributes to each polygon.

 Consider polygon attribute. If this option is selected, only the data that falls within the polygon with the specified attribute and value will be considered.

In case Data Filters option pane is hidden, an indicator in red color will be displayed as below.

4.1.1.3.3 Geo Bin

The Geo Bin option is to provice on-the-fly solution to aggregate the data in geolocation bin.

 Binning Method

TEMS Discovery provides two algorithms, by route distance and by location grid, for geo-location binning. If you choose to use route distance binning, the data within the distance of the defined binning size will be binned, whereas if you choose to use location grid binning, the data within the square area of defined binning size will be binned.

 Binning Type

The default binning type is by the nature of data. TEMS Discovery has pre-defined binning type for each metric by its nature, for example, use LAVG (linear average for Ec/Io, etc.). However, you can select user-defined option and select one of binning type for all the data to be geo-binned. The selectable

4.1.1.3.4 Listing Filters (Non-Composite)

The Listing Filters option is different from the Data Filters option. The Listing Filters option will not directly affect the statistics of displayed data. However, it does directly affect whether a project, dataset, file/device, or metric will be displayed under the Data Explorer tree view. Please be advised that these options will not affect the listing of composite dataset.

 Problem Sets. You can select a problem set as a filter to list only the datasets or devices that have the problem defined in the problem set. Be sure to click the Refresh button to refresh the Dataset tree view after any change to the selection of problem sets. This option only affects the dataset listing in the Data Explorer.

 Favorite. The Frame or Metric can be added to or removed from the favorite group through its pop-up menu. The collection of these Frames and Metrics can be named and saved to a favorite group. The Favorite combo box lists all available favorite groups. Once a favorite group is selected from the combo box, only the Frames or Metrics that belong to the group will be listed in the tree view. This option only affects the dataset listing in the Data Explorer.

 Date filter by. You can search the dataset within a certain period based on its processing date or collection date. You will need to click the Refresh button to refresh the dataset tree view after any change to the date criteria. This option only affects the dataset listing in the Data Explorer.

You can also select context menu shown below

to bring up the following dialog for defining date range for listing, so that only the file/devices which are processed or collected within that date range will be listed.

Other than the above date filtering, for each dataset, only up to a certain number of file/devices can be listed. You can select the context menu “Modify Max. Number Of Files To Be Listed For Each Dataset” to modify this maximum number.

To be more specific, you can also manually select the file/device to be listed from the following dialog which can be brought by selecting contaxt menu “Select File/Device For Listing”.

4.1.1.3.5 Search Dataset Tree

You can search the dataset tree for any label that contains the specified search text.

You can search only for File/Device name, or if you also want to search the script results, check the option Automatically generate script result if needed.

NOTE: The process of searching the script results may take some time, and you will not be able to cancel the process once it starts.
