This is a tool that is located on the Sample Adequacy section of the Sample Adequacy tab.
Function
The Split Sample by TOPS interface () is used to find samples where the TOPS data items change along the sample. In this interface, sample sections can be split into multiple samples based on changes in the TOPS items. The interface also provides the ability to disassociate a section of sample based on the changes in TOPS items. The interface is divided into 3 sections: Data Table Information, Sample Data Grid, and Button Controls.
(1) Data Table Information
The Data Table Information section contains general information about the selected Data Table. This section hosts the Data Table and Year dropdown controls, alongside these controls:
| Control | Used To... |
| Break on AADT Change Checkbox | Determine whether AADT will be used as a criteria for splitting samples. |
| Check Samples Button | Execute the Split Sample by TOPS function and populate the Data Grid based on the Data Year, Data Table, and Break on AADT options. |
(2) Sample Data Grid
The Sample Data Grid shows the results of the Check Samples function, indicating where TOPS item changes occur across a sample length. Segments then can be disassociated with a sample by using the checkboxes in the left-hand column. There are some controls found here:
| Control | Used To... |
| Save To Source Checkbox | Enforce that changes to the HPMS Data Tables are also applied to the HPMS Samples data source. |
| Export to Excel Link | Export the current table to Excel format. |
(3) Button Controls
There are two button controls that help users determine the saved/unsaved state of their inputted data. These controls are:
| Control | Used To... |
| Save Changes | Disassociate marked segments and update the TOPS table. |
| Discard Changes | Exit out of Split Sample by TOPS without committing changes. |
