About The Viewer

A.  Map Layers window

The Map Layers window is where you can turn layers on and off, change their transparencies, learn more about each layer, and download the data. The Map Layers window is organized into four main themes. When you click on each bar, that section of the menu is opened accordion-style and the list of layers that fall under that theme appears.

To turn a layer on or off, click the checkmark next to the layer.

To change the transparency of the layer, grab the slider and move it sideways.

To find out more information about a layer, click the “i” button to the right of the layer.

To download the data, you first need to select an area from the Select an Area dropdown box. Then, click the “i” icon next to any of the layers and click the Download button at the bottom of the pop-up window. Note that the high value habitat data that you download is actually a raster of the raw habitat scores, ranging from 0 to 1000. The colors shown on the Viewer are derived from the raw habitat scores, but are actually percentages of the cumulative area covered by each habitat score and all values greater than it.


B. Map Navigation

The Map Navigation tools allow you to zoom in and out and clear the map and start over.

The Share tool provides you with a URL that links to the map currently on your screen. It is a virtual way to create and print a map to share with others.

C. Markup Tools

The Markup Tools allow you to add text, drawings, and shapes drawn from uploaded spatial data to the map.

If you want to add the borders of shapes from a shapefile or kml file to the map, click on the shp or kml icon. These tools will not add any associated attribute information to the shapes or recolor the habitat values; they simply add a drawing to the map. You can also draw points from latitude and longitude coordinates listed in a spreadsheet by clicking the xls tool. These tools can be useful, for example, if you wanted to show the boundaries of your projects on the map.


The other four icons can be used to draw points, lines, polygons, and text on the map. These annotations stick to the map where you added them and will be visible in the correct place if you share the map with others.


To delete individual mark-ups, click the trash can icon. 

D. Selection Bar

The Selection Bar allows you to choose a watershed, jurisdiction, urban growth area, custom shape, or uploaded shapefile to summarize and view high value habitat relative to the habitats within the selected area.

Use the dropdown box to select the type of area you are interested in. If you choose watershed, jurisdiction, or urban growth boundary, you will be given the option of selecting a particular type from the dropdown box to the right.

If you wish to draw a custom shape or upload a shapefile, follow the directions that pop up when you choose that option on the Select an Area dropdown box.

Once you select a particular area, the Viewer zooms into that area and recolors the “highest”, “high”, and “full spectrum” layers so that you are looking at high value habitats relative only to the habitats in your selected area.

E. Area Summary

Once an area is selected, you can view statistics and other information about the area by clicking on the Area Summary link next to the Select an Area dropdown box.

Click on the tabs to view information about land cover, habitat values, parks and ownership, and, if a watershed is selected, facts about the watershed.

Under the Land Cover tab, you can compare the acres of land cover in each category between your selected area and the region as a whole. You can also compare your selected area to land cover in just the urban areas in the region.

The Habitat Value tab shows you the number of acres in your selected area that are in the “highest” and “high” value categories. It also shows the acres of riparian habitat that were evaluated to score riparian habitat, and of those, how many acres are considered to be high value riparian habitat.

The Parks & Ownership tab allows you to compare the acres of parks and natural areas, public or non-profit lands, and public or non-profit lands by ownership in your selected area with the region as a whole.

The Watershed Facts tab (visible only if you’ve selected a watershed) summarizes some key information about the watershed printed in the Biodiversity Guide of the Regional Conservation Strategy and directs you to the appropriate page for more information about the watershed.

F. Full Report

At the bottom of the Area Summary window, you have the option of exporting a PDF report. This report contains maps of the local and regional high value habitat in the area, the land cover, parks, and a copy of the map that you currently have on screen.
