Detailed Description

This video describes Step 2 of the Land Treatment Exploration Tool. In Step 2 the user defines their planned treatment boundary. The user can load a zipped shapefile or on-screen digitize their boundary.  

These tutorial videos were created to aid in the use of the Land Treatment Exploration Tool (LTET). These videos guide a user through the main steps of the tool. Each year, public land managers make decisions regarding restoration and rehabilitation actions that influence landscapes and ecosystems. Many of these decisions involve soil and vegetation manipulations, often known as land treatments. Land treatments include activities such as removal or alteration of plant biomass, seeding burned areas, and herbicide applications. These treatments were historically planned on a case by case basis with decisions about implementation approaches, methods, and operations derived from personal experience of past successes or failures. Modern adaptive management strategies strive to capture this local knowledge through time, both locally and regionally. In 2017, the U.S. Geological Survey partnered with the Bureau of Land Management to create the Land Treatment Exploration Tool to facilitate adaptive management of land treatments. The Exploration Tool taps into a wealth of information about past treatments in the Land Treatment Digital Library (LTDL), a catalog of information about all known treatments on public lands administered by the BLM in the Western United States.

Welcome to the Land Treatment Exploration Tool tutorial.  Step 2, select treatment boundary. In step 2, the user creates or loads the shapefile for their project. First I will show you how to load a pre-created zipped shapefile.  You simply click the top button, Upload a shapefile. Navigate to your zipped shapefile and select open to pull that shapefile into the Exploration Tool. There are also three ways to digitize a polygon on screen. The rectangle tool simply draws a rectangle with a held click and drag. The map will automatically recenter as the polygons are modified. The polygon tool adds a vertex with every click. A double click completes the shape. The freehand tool is similar to drawing with a pencil. Press and hold the left mouse button to create a polygon as you drag the mouse. Release the left mouse button when you've completed drawing the polygon. To modify a polygon, simply click on the shape and the vertices will appear. Clicking the grey points will modify the shape, while the white points will also create additional vertices. If you want to remove all shapes, you can click the 'Remove All User Polygons' button. Each polygon is listed on the left where you can zoom to or delete each shape individually. For this example, I will just use the wildfire perimeter loaded from the zipped shapefile. The polygons uploaded or drawn on the map are exportable as a kml, geoJSON, or shapefile. Clicking 'Next Step' takes you to step 3.
