District shading added to HPOWEB

Last month saw a change to the symbology used in HPOWEB; this month sees a similar small, but potentially effective, change in the way historic districts and other boundaries are displayed.

HPOWEB users will notice that semi-transparent, colored shading has been added to all historic districts (HDs) and other historic resource boundaries.

The new shading layer appears in the HPOGIS Layers table of contents,  Users may uncheck and check the entire shading layer, or individual sublayers.

The shading for each class reflects the color choice of the associated points; so, National Register HDs appear light blue, Study List HDs appear light green, Determined Eligible HDs appear light orange, and Local HDs appear light pink.

Where two or more district or boundaries overlap, a blending of these colors appears.

This change will be most effective in highly complex, urban areas such as Wilmington.  Below is a screen capture of what eastern Wilmington looks like in HPOWEB without shading — it is difficult to say which portions of town are inside historic districts:

Now, with shading, it is much more easy to discern the portions of town inside historic districts:

If you need to view an aerial image of a building with absolute clarity, simply uncheck the shading.  The boundary outline will still display, unless you uncheck that as well – outlines are listed below each point layer.

Boundary outlines can be turned off by unchecking the box beside its name
