Hi Hannah,
As Val mentioned yesterday I'm in the Scottish Borders polygonising the HER overall - as well as also doing the same for the Stirling (outside the Loch Lomond and The Trossachs National Park) and Clackmannanshire in due course next year. My post is a specific one to do this work.
As you mention there lots of questions to answer from the start of the process - I've been in post since the start of July and created an 'instructions book' for the Scottish Borders part of the project. (Stirling and Clackmannanshire may differ in their requirements as I come round to their work). At the recent SMR Forum Scotland meeting Claire for Shetland, and I for my project also, provided introductions and updates to our work. In some respects we are similar, though in other things we differ in our polygonisation based on our starting points (such as previous polygons, previous work of whatever sort - whether or not already GIS'd, what HER data, resources and sources we have to hand and so on).
In essence my work;
- extracting the data (both national and local records) to a set way (parish- and search-based seems to be working)
- sifting (as the known knowns, known unknowns and unknown unknowns as you recognise) to remove those incapable of polygonisation (mainly GIS-based work in my case)
- polygonisation of those remaining (currently an ad hoc mixture of polygons, points and lines with gaps and overlaps between the various geometries), with all the choices on what and how to polygonise those
We are a SURE user here, so feed things direct into the national record as 'our' HER here. There are about 20592 entries in our national record for the Borders, 15754 points, 1147 lines and 2050 polygons in the old HER. There has been some previous polygonisation carried out for areas and thematic projects by Historic Environment Scotland which I'm also looking at, checking and amending if necessary. My sifting methodology means about 16805 should be capable of polygonisation overall by whatever means - whether that by hand or more technically-based - which may also be possible depending upon the original data.
I've done several trials of areas across the Borders to cover the variety of the records here, and there are thoughts on that old hoary subject curtiliage.
As work in progress, and including the created polygons for selected search areas, it is on-going something to do to explain what polygonised and what not for the variety of HER users. The resulting HER will be still a mixture of points and polygons, but it will be a more clear division of why the differences.
I'm happy to have a discuss, and can send you on my SMR Forum Scotland presentation and 'instructions book', if you want.
Best wishes,
Keith

Thanks very much, it sounds like we are on the right track, especially regarding standards.
We would want to be looking at how we represent the HER data within our GIS, examining issues such as: do we have a single point for each record? When do we create polygons? How consistent are we and where are the gaps? What can we do to ready our data for future uses e.g. online access? - giving us a consistent, standardised approach to these issues that has been formalised into some sort of document.
Will take a look at the links suggested, very much appreciated, thank you :-) If there is any more information on this sort of thing that anybody has come across or dealt with similar issues it would be so helpful to hear about it,
Thanks again!
Best wishes,

Hi Hannah
What do you mean by GIS strategy? I'm guessing you mean guidance on how to polygonise sites?
I have memories of starting to draft something like that when I was at NYCC, but don't have a copy
From memory though, I vaguely recall that there were already some standards/guidance around this which might help. I am sure Historic Scotland has produced a report on polygonising stuff, though can't recall what it was called. There is also information on this at IFP http://archaeologydataservice.ac.uk/ifp/Wiki.jsp?page=SectionC.11 There might even be some things in MIDAS Heritage - but you would have to check.
Hope that helps
Best wishes

Subject: GIS Strategy
Hi all, we are wanting to make a start on the creation of a GIS Strategy for our HER and was just wondering if anyone else has undergone this process, and if so if anyone has any advice/useful links/examples they are aware of please?
Thanks!
