Using the Land Use Change Mapping Tool

• Click on the stacked-layer icon in the upper right of the map to view the different layers that you can toggle on or off.
• While you can leave the “USA Detailed Streams” layer on, it is best that you only select other layers individually, one at a time.
• The first layer “Change in Land Use” will allow you to see which parcels have changed the most between the study period of 2013 and 2018 according to federal high-resolution (1 meter) land cover data. Then, you can select one of the other layers associated with nitrogen, phosphorus, and sediment to see how development or changes in natural land covers have increased or decreased pollution to the nearest streams over that time period.
• Note that you can click on individual parcels to view the associated land cover or pollutant loading data associated with the individual parcel.
• The shading of each parcel reflects that changed data, but does not show actual extent of the land cover change.
