Creating an advanced filter
- Wouter Gravendeel
An advanced filter is one of three available filters in Glex. It takes a little more time to set up than the preset filters but gives a lot more freedom when it comes to parameters.
Instructions
The advanced filter can be found under Windows ⇒ advanced filter. The filter window will open as a side panel where you can select add filter to create a new advanced filter.
When selecting + Add filter you will be given the choice to load an existing filter or create a new one. Loading a new filter will add it to the Advanced filter window, where you can toggle loaded filters on and off. Creating a new filter will open the filter creation menu.
When creating a new filter, you first have to select the type of data you would like to filter. After selecting the datatype it is possible to add rules to your filter.
In order to filter the data, you first have to select what attribute you want to restrict and add a rule to the filter. Some attributes give a selection, while others allow you to select a data range.
Now there is a bit of a logic puzzle when creating these filters.
If you add a new filter row to a rule, the filter will find either objects with A or B
If you add 2 separate rules, the filter will find objects with both A and B
You can also chose to find object without a specific parameter
Instead of a range you can select different operators like “greater than” or “equals to”
The example underneath will filter non-producing (D) fields discovered in or after 1990 (C) containing either oil (A) or gas (B), before you create a filter you can see wether there are actually results for it at the bottom.
Give the filter a name and a description and click create. It will now automatically be loaded into the list of loaded filters, where you can activate it, and
appear in the + add filter list.
In order to list the fields that comply with the filter you can activate the inspector layer found under Windows ⇒ inspector.
