About the Hopewell History Map

– Explore the Hopewell History Map (separate site) –

The interactive Hopewell History Map uses a map interface to explore information and images on historical properties in Hopewell Borough.

It is built on the familiar Google Maps platform, and so has the usual map controls (map type, zoom, pan), plus additional historical property annotations displayed as street numbers.

Browse the street addresses in the Map or Table, and then click a property to view the available information in the other panels, including photo and postcard views in the Info Panel.

  • Zoom in on the map to see Hopewell properties annotated with street numbers
  • Click a street number on the map (e.g., “12”) to see property information
  • Blue street numbers with a caret (“^”) are historical, with additional information
  • Street numbers with a plus sign (“+”) have associated images
  • Street numbers with an equals sign (“=”) have associated documents
  • Click on the left/right in the Info Panel to cycle though available images
  • Click on the property address heading (top left) in the Info Panel to view additional information and open a site survey document
  • Click on the image name caption (bottom center) in the Info Panel to view additional information on the image and open the images fill-size.

This is an prototype designed to explore the possibilities of this kind of interface for historical information, and subject to changes. The underlying data also is only partially implemented. Comments welcome.

The Hopewell History Map is designed to be used in standard Web browsers (e.g., Firefox, Chrome, Safari, Internet Explorer, and Edge). The interface is designed for use on computer displays and on mobile tablet devices. The display automatically simplifies for smaller windows and smartphone screens. However this volume of information does not fit well on smaller smartphone displays, and smartphone browsers have difficulty with full-screen Web apps.

Historical Sources and Dates

The list of historical properties on the map (street numbers in blue) is a work in progress. The current list was assembled from several sources, including the 1985 Cultural Resource Survey and historical books and maps. The date provided for a property then may be an exact year (if known), or circa an approximate year (c), or no later than a specific year (“by” the date of a published book or map). The sources and associated dates currently used are:

  • Date from Hopewell Borough 1985 Cultural Resource Survey
  • 1887 – Found on Fowler 1887 panoramic aerial map
  • 1891 – Listed in (or date from) “Hopewell Boro Buildings in 1891” compilations from Hopewell’s Past by Betty Gantz (1987)
  • 1897 – Found in Healthful Historic Hopewell booklet (1897) – Normer Gray
  • 1909 – Found in 1909 Hopewell N.J. booklet – Fry & Whitehead
