Hi Emma We can't do Polygons at the moment (it should be happening this year...), so it's a bit moot for us. I do have a couple of GIS layers of some big surveys/linears, but I think the transparent route is one I would recommend. We currently use this for Parish records, each parish has a transparent body, but edged, Polygon, which "links" (I use the term loosely...) to an HER record which acts as a digital Parish file. Useful for flagging up sources you know cover an area but haven't been able to trawl yet. Best wishes Nick Boldrini Historic Environment Record Officer Ext 267008 From: Issues related to Historic Environment Records [mailto:[log in to unmask]] On Behalf Of Whitcombe, Emma Sent: 03 August 2015 12:31 To: [log in to unmask] Subject: Large event areas Hi all, We're having a discussion over at Wiltshire about how to deal with Events that cover large areas of the county/HER scope area. We have several of these (e.g. large AP interpretation projects) and have not previously come to a solid decision about how best to map them. Clearly it is important to be able to mention the source to enquirers when carrying out a spatial data search, but they are also so large that they will make it difficult to distinguish smaller polygons that sit underneath them. (This is a particular issue to us as our backlog/resourcing situation means we currently prioritise entering Event records over Monument records in most cases.) We were wondering how others in the HER community deal with this? Do you make a huge polygon that covers half the county? Do you place points in the centre of every parish that is covered? Do you not map them at all? Do you make a new layer specifically for big Event polygons, and, if so, do you nest this within your main Event layer or give it its own place in the layer tree? If you have a specific strategy for this, what are the pros and cons of your decision? We use HBSMR, but answers from people on other systems are also welcome. Thanks!
