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:

Wilmington, NC with shading turned on

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

3-1-2013: New version of HPOWEB coming soon

The North Carolina Historic Preservation Office launched HPOWEB in the spring of 2011.  A lot has happened in the intervening two years and we are excited now to announce the imminent release of version 2!

As we perform some long-awaited data migrations and software tweaks, you may notice some minor changes in the existing HPOWEB website.  For one, we will slightly alter the symbology of the points, providing them with what we believe is a cleaner and more modern feel.

For example, here are two screen captures of Bertie County that compare the old and new symbology:

Bertie County (old symbology)

More importantly, HPOWEB users will be able to search all data classes at once.  Currently, a user who wants to locate a resource based on a name, description match, or Site ID number might have to perform up to three separate searches before finding their point of interest (with “Search NR,SL, DOE”, “Search Local Landmark/District”, and “Search Surveyed”).

With the changes taking place, users will be able to search the entirety of the mapped historic resources, regardless of their designation or landmark status.

But wait, there’s more!

  • You may have noticed that we have scanned as PDFs all of the National Register nomination forms.  These are available in an alphabetic list on the NC HPO website (here), as well as from within HPOWEB.  The information box of any National Register listing includes a hyperlink to its nomination form PDF.
  • We have now mapped over 50,000 resources, including all designated resources — those with National Register (2800+ resources), Study List (4200+) , and Determined Eligible (1200+) status.

The new version of HPOWEB will feature several new enhancements and tools.  Look for a future announcement about those.

Finally, a note to our heavy-duty GIS users, who may be directly consuming our published web map services.  (If that sentence makes absolutely no sense to you, then continue about your day.  We’ll talk again soon!)

Currently, the NC HPO is delivering resource data (point and polygon) through a variety of WMSs, one for each feature data class (National Register, Study List, Determined Eligible, Local Landmark, Surveyed).  We are in the process of changing the structure of our geospatial database and expect to deliver the same data through ONE service, with multiple sublayers for each data type (including point and polygon).

We will inform the public of the new WMS once it goes live.  If you wish to receive an email notice about the expected change date and WMS name, please contact the GIS team at either michael.southern@ncdcr.gov or andrew.edmonds@ncdcr.gov
