Exegesis SDM is now part of Idox

We are pleased to announce that Idox plc, a leading supplier of specialist information management software and solutions has acquired Exegesis Spatial Data Management Ltd.

Idox acquisition of Exegesis SDM

The acquisition of Exegesis will considerably improve Idox’s product offering and is highly complementary to Idox existing offerings across the Built Environment and asset intensive sectors. The established mapping technologies and knowledge within Exegesis will enable Idox to provide much needed data and services that allow for location visualisation which is an emerging requirement as organisations digitise their operations. Idox has placed an increased focus on its GIS capabilities recently, notably with the purchase of thinkWhere in August 2021.

The acquisition will provide Exegesis with the investment and resources needed to support further growth, as part of a larger, progressive software business.

As we move into this new phase, Exegesis will continue to provide high quality solutions for customers and look forward to the future as part of Idox.


Church in Wales Ministry Area digitisation project

Following a reorganisation of the existing Church in Wales parish system into one of amalgamated Ministry Areas, Exegesis SDM Ltd have been commissioned to provide accurate, contiguous digital mapping of the boundaries for these new groupings. We had previously worked with Llandaff diocese to produce digital maps of the proposed Ministry Area boundaries, which were used in the consultation process. Now, all dioceses will have their Ministry Area boundaries mapped, along with church locations, church halls and rectories. This will provide a definite and consistent set of mapped data which will also be made available on the Church in Wales website

Further details of these services can be found on our GIS consultancy pages.

Our virtual instructor-led courses have matured

We have now been running virtual instructor led training courses for just under 3 months and have found that our 2 day GIS courses work best when run as 4 sessions spread over three days. Trainees have noted a number of interesting benefits to the format:
•    ability to use their own copy of their chosen GIS
•    time between the sessions to try out the ideas on their own data
•    time between sessions to keep up with other work commitments
•    and they like the 2.5 to 3.5 hour sessions which is the perfect duration for this type of technical training

These are in addition to the obvious advantage of being able to do the courses without travel or coming into contact with other people.

This is what trainees have said:

•    I really enjoyed the course and it has opened my eyes to the possibilities.  More importantly the delivery was excellent, never a dull moment.  Carol was engaging and enthusiastic and had all the answers to any question which I had. 

•    You did an amazing job with what would have been very difficult training - very relaxed, friendly and fun approach to the course

•    The course was exceptionally well delivered and the tutor was a brilliant instructor - very patient, encouraging and knowledgeable

Wales bait digging survey

Bait digging is a particular issue on certain shores in Wales, especially where the volume of digging is causing long term changes and damage to the habitat. Natural Resources Wales (NRW) wanted to investigate ways of assessing and monitoring this impact.

The aim of the project was to establish the suitability of aerial imagery taken from Unmanned Aerial Vehicles (UAV) to investigate the spatial and temporal extent of bait digging at selected sites in Wales.

Sites were flown at low tides and ortho-rectified seamless mosaics produced. Shore survey and ground truthing was also undertaken, and control holes dug to investigate the persistence of bait digging evidence on different shores. The shores were revisited to assess whether the control holes were still visible, to give an indication of the persistence of damage. The ortho-rectified imagery was used to create bait digging intensity maps on a variety of shore types.

We also investigated the potential to use localised terrain models to help identify areas of bait digging.

ISO-9001 Quality Management Certification Renewed

In June 2020 ESDM renewed their ISO-9001 Quality Management certification following a successful external audit from QMS International. By achieving our ISO-9001 certification, ESDM is able to demonstrate to customers and suppliers that the systems and processes we have in place meet the high standards for quality management set out by the International Organisation for Standardisation (ISO). In applying the ISO-9001 standard we are continually improving our working processes, via customer feedback and performance monitoring.

Keeping your data secure with Duo two factor authentication

We can now offer two factor authentication as part of our security upgrades.  We have recently signed up as a Duo reseller, and so we welcome customers to enquire about our two factor authentication methods to help further secure our already strong logical security approach.

Peatbog restoration surveys

The demand for aerial surveys of upland and lowland peat bogs has never been higher than over the past 2 years.  We are well into the main survey season now and so our eBee Plus RTK fixed wing drone is being used to survey a range of sites across the country.

We are also increasingly being asked to create fly-by videos at the same time as the vertical surveys using our multi-rotor drone.  These videos are excellent for giving an overview of the sites or for use in public consultations, helping to make sense of the habitat and site features within the landscape.  Further details can be found on our air survey pages.

Virtual training courses

We now offer new virtual GIS training courses which are receiving great user feedback.  These courses have been running for the past 6 weeks and are receiving the same excellent trainee feedback as our normal courses! For further details contact Carol or visit our training pages.

Keeping your data secure with Cyber Essentials Certification

We have been awarded our updated 2021 Cyber Essentials Certificate, a UK government assurance scheme which demonstrates our good practices in information security.

Earlier this year, we also completed our migration of older operating systems to the most modern Microsoft Windows operating systems. This again assures our customers that we are at the forefront of increased security, performance and reliability.
