Kelvin Wong of UCL is organising an Introduction to 3D GIS and BIM. This free event promises to be a great introduction to the subject and as of today (09/01/2017) there are only three places remaining so book pronto!
The day will be split into two parts. The morning session will focus on 3D GIS, starting with a short lecture introducing the topic, followed by an overview of current research trends in 3D GIS. This will be followed by a practical session where you’ll learn how to create a 3D City Model using FME software, and visualise this model in Esri’s ArcScene.
The afternoon session will commence with a short introduction to Building Information Modelling and how it is similar to, and different from, 3D GIS. This will be followed by a second lecture on approaches to integrating BIM and GIS. You’ll be given an opportunity to undertake a small BIM/GIS integration task using software including Autodesk Revit, FME and ArcScene, and at the end of the day, you’ll have integrated the 3D City Model from the morning session with the BIM data from the afternoon session.
The event is free to attend. Places are limited, and will be allocated on a first-come first-served basis (20 in total – you will be waitlisted if you are not allocated a place). You are expected to have some GIS experience (e.g. using ESRI tools) to participate and will have an interest in both GIS and BIM.

Archaeogeomancy were pleased to be commissioned to build a system to automate an existing workflow for handling and reporting on geospatial information. The workflow is used by a major land management organisation for evaluating and responding to planning applications on behalf of their clients, the property or landowners. Automation allows non-specialists to undertake the map production and saves considerable time and money. Continue reading
I was dismayed to find the latest copy of the Valley News arrive through my letterbox featuring a front page article entitled Stones bypass back on the agenda. The article comprises the opinion of a single Wiltshire councillor, Cllr. Ian West, regarding what he thinks should be done about the A303 around Stonehenge. Having worked on many of the A303 and Visitor Centre proposals over the years, I find it sad to see such a rehash of old, stale views put forward as news in such a way as this. Continue reading
Following on from the last update concerning the GSTAR web services, the final pieces of infrastructure for the case studies and demonstrator are nearly complete. Building on the API, a GeoJSON output format has been added so that results from GeoSPARQL queries can a) be accessed via a simple URL as with all other outputs and b) visualised using a web map or indeed any platform which can consume GeoJSON. Continue reading
The final batch of source data has now safely received and is being processed for inclusion in my GSTAR project, kindly provided by the good people at Salisbury Museum. Thanks in particular are due to David Balston for assisting me and Adrian Green for giving the necessary permissions to use the data. Continue reading
Yes, it’s that time of year again: Time for the annual Day of Archaeology. And once again, my day does not involve any temples in remote jungles, crystal skulls or raiding any tombs. Indeed, as has become the norm, it does not even involve any digging of holes, artefacts or suchlike.
Yep, archaeology involves a much broader range of activities than many folk believe, many of which are lab based and/or computer based with the result that some archaeologists (myself included) rarely get to see daylight let alone travel to distant far off lands in search of ancient peoples. And this is one reason why I love the Day of Archaeology so much as the range of posts each year covers just about every aspect of archaeology and cultural heritage and goes a long way towards showing what we, as professional archaeologists, really get up to, shattering stereotypes perpetuated by the likes of Indiana Jones and Lara Croft.
Anyway, here’s my post for this year which focusses on the usual range of geospatial and geosemantic stuff and not being chased by angry tribespeople or making dramatic and implausible escapes from imminent danger and almost certain death (although I did get a small electric shock off a laptop power supply this morning…)
With all the source data prepped and ready to go, the next step is to build some demonstrators to show how such geosemantic resources can be used in practice. Whilst very powerful, a Sparql endpoint is not the most friendly way of interacting with data resources, especially from within a web based application where options for programming are a bit limited. There is still quite some debate on this topic which will be covered in more detail in the thesis (watch this space; still on track for submission 1st/2nd quarter 2016!) but the approach I have opted for is an API using web services to provide a range of outputs via a combination of URLs and parameters.

The following visualisations were produced as part of the Fingle Woods and Castle Drogo Aerial Survey Analysis and Interpretation project, recently completed for the National Trust. There is a visualisation for each hillfort in the study area: Prestonbury Castle, Wooston Castle and Cranbrook Castle.
The visualisations were produced from a Digital Terrain Model (DTM) based on LiDAR data provided by Bluesky at 25cm resolution. This DTM was also used to produce a Local Relief Model using one of the ArcGIS tools currently being developed by Archaeogeomancy for the National Trust. The LRM was then draped over the DTM, exported as VRML and uploaded to Sketchfab. Continue reading
