Interactive Map:

ArcIMS is slowly being abandoned by ESRI, so maintenance of the ArcIMS maps is becoming extremely difficult. We have decided to migrate this map interface to a more sustainable software stack using non-proprietary software. We will begin the migration to GeoServer and OpenLayers as soon as possible, but until then we apologise for any inconvenience.

Help for using the Interactive Map

An Interactive Map has been provided to enable you to examine the various spatial data compiled throughout the survey using basic WebGIS tools. To begin using the map click the button labelled 'Switch On' found in the box above.


Each map contains several layers grouped under the following headings:

  • Archaeology
  • Plan Elements
  • Metrics
  • Survey Data
  • Base Map

Layers can be selected either singularly or as a group. Toggling the group visibility icon group visibility icon will display/hide every layer featured within the specific group. To display a single layer within a group, the group must be opened and the relevant layer can then be enabled/disabled by selecting the layer visibility icon layer visibility icon. However, only one Base Map layer can be displayed at any one time.

A layer can be made active be either clicking the relevant radio button or by clicking the layer title. The layer will become highlighted when it is active.

The Group/Layer panel can be hidden by clicking on the vertical grey button marked with an arrow. The arrow button will slide toward the left of the map area and the map will be re-rendered filling the whole area. Clicking the arrow button again will show the Layer/Group panel. When the Layer/Group panel is hidden/shown the active tool will be deselected.



The various tools found in the tool panel on the right of the map allow a further element of interactivity. There is a handy text tip next to each button on the interface to explain what each button is for, but on this page we go into a little bit more detail:

zoom in buttonZoom in - Click on the map to zoom in (the map will be centred on your mouse click).
zoom out buttonZoom out - Click on the map to zoom out (the map will be centred on your mouse click).
zoom full extent buttonZoom to full extent - Zoom to the extent of all the layers within the map - this is a quick way of getting back to the map's starting position
pan buttonPan - Click on the map and drag it in any direction to change the area of view.
identify buttonIdentify - Click on a feature on the active layer to see the data attached to it. The data will appear in a popup window.
rectangle select buttonRectangle select - Use your mouse to draw a rectangle on the screen to select a group of features within the active layer. The associated data from these features will be displayed in a popup window and the selected features will be highlighted.
clear selection buttonClear selection - If you have any features selected/highlighted, this tool will unselect them.
show legend buttonShow legend - Show a map legend of archaeological features in a popup window. Point data and basemap information is omitted.

The tool in use will be highlighted by a red box.


General guidance:

Be patient! Every time you zoom, pan, refresh or query the map, a request is sent to the server and new image is created and delivered to your desktop. Whilst this request is being sent, do not try and send extra requests as this will produce error messages. Your browser can only send and receive one GIS request at a time so don't push it!


The GIS files are also available as downloads if further functionality is required.
