Hi Nick, At the Gloucestershire SMR we contact the larger units who we know use GIS for the trench outlines (events) and any feature shp files (monument). We extract features by date and type, for example Roman ditches and assign them a monument number. We may assign a smaller group of ditches another number if for instance they are part of an enclosure. I have managed to get data from Wessex Archaeology dating back to 1999! Most data sets we get are varied as they are produced for the archaeological units requirements but they seem to be useable with out too much hassle, getting trench locations for large evaluations is very useful, they are more accurate than digitising on the GIS and a lot quicker as you only need to copy and paste. Especially as many are now using GPS and Totalstations on a regular basis. The Units I have contacted regarding GIS are happy to do so, we also make them aware that we can supply SMR data as shp files and so they get data and we get data back , so a win win situation. As for data standards I guess the ADS Guides to good practice would be a good starting point. We also get dwg and dxf files from units using CAD http://ads.ahds.ac.uk/project/goodguides/gis/ http://ads.ahds.ac.uk/project/goodguides/cad/ I haven't had any problems with the data supplied by units, the only problems arise when we get data from mapinfo in TAB format opposed to shp files (we use ArcGIS). Regarding Big Events, we keep our SMR polygons hollow with a simple outline and so other features are not masked, things like SSSI's and Conservation Areas do have a filled interior but are arranged below the SMR data, we don't use HBSMR. Hope that helps On a different subject entirely, today is my last day as SMR assistant, I have been here (Gloucestershire) for a year and having come from the commercial digging side of things its nice to see the other side of the coin! I am off to do a PhD in Spatial Analysis of 3 Late Neolithic Settlements in North Holland and I will be based at the University of Groningen, Holland for 4 years! Its been a pleasure working in the SMR/HER environment and I hope I have made some useful comments over the course of the year, I wish you all the best for the future. Gary From: Issues related to Historic Environment Records [mailto:[log in to unmask]] On Behalf Of Nick Boldrini Sent: 20 October 2009 09:22 To: [log in to unmask] Subject: Data Exchange Hi HERO's one of many things I am pondering is data exchange. By this I mean exchanging digital data of event, monument finds etc data with different groups. I have had some experience of this, we have received some data from Contractors, quite a bit from some Community Archaeology Projects, and shared data with Neighbouring LA's. The data has varied from GIS layers which we don't need to incorporate into the HER fully (eg neighbouring LA data) to GIS and databases we would want to bring in fully. There are lots of issue relating to bringing the data into the HER (Copyright, actually importing the data and related data standard issues, etc). However, when talking to people about this I am regularly asked if there are any set standards to use when they create the data. Obviously I mention MIDAS and INSCRIPTION and their eyes glaze over... I am also aware that there are various initiatives looking at these issues eg I think it was suggested OASIS to look at getting GIS coverage of events from contractors at HER Forum in Sheffield (or was it HBSMR UG?), and also ASPIRE is available (though this seems to have stalled). The point of all this is one of the things I am trying to come up with is a quick, short and Plain English introduction to what information an HER would require from people as a minimum, to make the records useful, and easy to integrate. Has anyone looked at this or produced anything like it for their HER? I would also be interested to hear any experience of data swapping and things to avoid/worked well when getting data from contractors local societies etc. thanks best wishes Nick Boldrini Historic Environment Record Officer Direct Dial (01609) 532331 Access your county council services online 24 hours a day, 7 days a week at www.northyorks.gov.uk<http://www.northyorks.gov.uk/>.
