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. For further information on our certification please see
