To get a better understanding of the wood flow and transportation objectives in the Crowsnest Pass we will start with harvesting and transporting wood from a single block before we run the scheduler.

	Note
	Click the 'Seral Stage' layer in the Legend Panel to select the block layer (border will appear raised when it is selected). This will activate some of the data exploration tools on the toolbar. Using the 'Query Tool' form the following expression:BLOCK = 13352. Zoom to the selected block using the 'Zoom to Selected' feature.

Note

Right click on the block in the Map Viewer to open the block menu. Select 'View and Edit Treatments' to open the Treatment Viewer for the block. Schedule a 'CC' treatment 20 years into the future (the X axis is represented in years). Return to the Map viewer and Zoom out several times to see a larger extent using the icon. You won't see your changes to this block until you scroll ahead to the corresponding planning period in the Map viewer (scroll to period 4).

If you clikc on the button that 'Unselects all records in selected table' you will notice that our harvested block has turned yellow to represent the 'Regen' seral stage (see Figure 28, “Results of 'CC' harvest for block 13352” below).

Each block in the dataset has been linked to the road network. When a block is harvested the model makes a decision about which destination should receive the wood and then tracks the route to mill and the associated costs.

Other valuable information about the routes in the model can be found in the corresponing route attribute table. This table is similar to the block attribute table but corresponds directly with the route. This table contains the original route shapefile information, as well as additional calculated attributes from Patchworks.

	Note
	Let's take a look at the route table while we only have a few active roads to look at. In the Legend panel of the Map Viewer select the layer 'Volume flow to MILL1' so that it appears to have a raised border. Use the 'Show Table' icon to open the 'Routes to destination.MILL1' table.

	Important
	Each destination in the model will have a route attribute table that describes the segments and costs associated with each destination. A 'Network' table exists that combines the information for all routes into one table.

Active routes are those line segments that have volume flowing over them in a particular planning period. To find the active segments we can query the route table.

Note

Be sure the scroll bar on the route table is at P:4 Using the 'Query Tool' on the route table toolbar construct the following expression: VOLUME > 0 There will be 302 records selected, meaning 302 individual road segments are used to haul the harvested wood from block 133352 to MILL1. We can order these segments by sorting them in descending order on DISTANCE. Promote the records back to the top of the table to see them using the icon.

Scrolling to the far right of the table you will find information about how much volume flowed over each segment, what direction the volume flowed, how much it cost to haul, how much of the road was built and how much it cost. This table provides valuable information for diagnosis errors in the network, creating map layers and route reports. For more information see the section called “Route Tables”.

Our block also has an active route leading from the block to the mill. In the case of block 13352 the wood is flowing to MILL1 off the south end of the unit (You can zoom out to the full extent to see the entire route). The route that has been selected is the initial default route, and may involve construction of new candidate segments.

Now that we know how far the wood had to travel from the block to the mill and the exact route that was taken we can begin to explore some of the objectives for the Crowsnest Pass as a whole. We can get a better understanding of this by opening the necessary target charts for the harvest quotas and transportation objectives.
