Using the Map
While the map is largely intuitive, there are some quirks which are useful to know about.
Top of Map, Left Side
Zoom In / Out
The map is very responsive to mouse or finger movements. The opening view is of Nelson (our area of study) but the map will expand to a much larger area, since it is based on GIS technology. If the map zooms out of control, simply press the home key to return to the original view.
Magnifying glass, dark: This is a search function, specific to the Lot ID. The lot ID’s are indicated at any of the articles which are tagged for the building site project.
Clock: Clicking this activates the timeline, which appears at the bottom of the map. The timeline runs at two speeds (you can select).
It starts as a single moving point in time, but you can manipulate it to create a span of years.
Activate the looking glass. This gives you a movable circle which reveals the Lidar (topography) underneath.
Magnifying glass, light: This allows you to search by current street address.
Top of Map, Right Side
The map is set to a default view which reveals the area of the subject matter. In the more densely settled areas this puts the cellar hole icons close together, and not all of them are visible. However if you zoom out (using the + – tool, or using mouse or finger movement (on tablets) those will be revealed. Clicking on the icon will give you information about that site. If you click on an icon and there are others “underneath” it, the additional information may be revealed in the pop-up box.
The Location ID is our internal reference, based on a commonly used grid format. The Struthers and Wadsworth IDs refer to the two main sources we have for this information – you can read more about that here. In many cases we have a short article about the location, which you can reach through the More Info link.
