When using Tree Plotter, there may be cases where you want to summarize and visualize sub-sets of your inventory data based on specified attributes. This can be done using the Advanced Filter tool, which is the bottom tool of the in-map tool bar (located at the top left of the map area).
Click on the tool to open up the Advanced Filter window. Remember to look for blue text marked “Read Instructions” for in-app tips. To get started, choose an inventory layer to filter. Next, look through the fields below to see if the one you’d like to filter by is included. If it is, click the check box next to the field to expand it and then check the boxes next to the selections you’d like to filter by. If the field you want to filter by is not present in these initial fields, click the Add Field dropdown to bring up a list of supplemental fields that can also be added. Clicking one of the fields in this dropdown will add it to the filter. When you are satisfied with your choices, click Apply. To clear all filters, click the Clear Filters button.
The Advanced Filter also has the capability to filter points based on spatial location. Click the Filter By Map button to start drawing a polygon around the data you’d like to analyze. Each click when the drawing tool is active will add another point to the polygon. When you’ve captured all of the desired data, double-click to finish the shape.
Note: Toggle Polygon Visibility will show or hide the border of the shape drawn. Clear Filter By Map will remove the filter.
You can now view updated statistics in the Stats tools and Interactive Legend as well as export the filtered selection to an external file. Be sure to clear all of your filters when you’re done with the tool.
If you check the Bound Map to Results box underneath the Add Field dropdown, when you apply a filter the resulting trees will be centered on the map. This is a quick way to zoom into the map and see just the trees you are interested in.
It is possible to save a filter as a View Filter by selecting the Save View Filter button
after applying the filter. You will then have the option to either create a new view, or overwrite an existing one. These saved View Filters will then be available for quick and easy access in the View Filter dropdown within the Interactive Legend.
