At two o’clock in the morning on 19th July 2004, 36 Young Explorers, with nine Leaders arrived at their camp site in the shadow of Longido in northern Tanzania some one hundred kilometres to the east of Ol Doinyo Lengai. 

These Young Explorers were a BES expedition who would walk across the savanna on the floor of the Rift Valley to Ol Doinyo Lengai then climb its steep flanks before trekking across the Crater Highlands to mankind’s birthplace at Oldupai Gorge on the edge of the Serengeti plains.

This was a five week BES expedition to the Gregory Rift in northern Tanzania.  On returning from Tanzania a ‘blog’ site was set up by Hugh Anderson to make the ‘science’ carried out during the expedition available to anyone interested in the material, and to provide a site where members of the expedition could tell their story.  This ‘blog’ was no longer evolving so this new site has been created by Hugh Anderson to replace it.

A potted history of Hugh’s career was published in Geomatics World on his retirement from Leica Geosystems.

This site is continually evolving with photographs and panoramas added from time to time and information on creating your own panoramas.

One evolution of the site is to include links and information on projects in the area visited by the Young Explorers in 2004 in Northern Tanzania around the Arusha area.  These are projects local to the area, which are helping the people in the region to find their way out of poverty as epitomised by the School of St Jude’s motto “Fighting Poverty Through Education”.  The projects are always looking for Volunteers and Sponsors to progress their work and you can find more information by visiting  my East Africa page.

This site also contains a section on Photographic Intersection, the low cost method of using photographs to accurately measure and record points in three dimensions.

The site has continued to grow with information added about the Ancient Technology Centre in Cranborne, Dorset, and The Church of St Mary in Easton Neston, Northamptonshire.

There is no connection between BES expedition to Tanzania in 2004, The Church of St Mary in Easton Neston and the Ancient Technology Centre in Cranborne other than they all involve me and share the same site as the material posted here is generated by me. - White Logo on Red TreeThis site contains photographs, many taken during the expedition.  These images have been kept to a low resolution so as to be small in size for speed of loading over the Internet.  If you wish to use these low resolution images directly from this site you are free to do so provided copyright is acknowledged to Hugh Anderson and the site address,, quoted as the source of the images.

These images are available at much higher resolution than as displayed on this site.
If you wish to make use of these higher resolution images please contact me at

Please provide as much information as possible about the intended use of such images as I will probably be willing to provide them at no cost if the use suggests this is the best way to proceed.

Please respect the information on this site, which is posted in good faith.

Once a ubiquitous feature in the landscape these structures are now few and far between, but knowledge gained by constructing these buildings has lead to them being better understood and the skills to build them learned.  You are able to have your own Iron Age Roundhouse built or courses on the construction of these buildings by contacting Anthony Brown.
Measurements fro 360° Panoramas   Measurements from 360° (Spherical) Panoramas
360° Panoramas have properties that can enable Angles (both Horizontal and Vertical) to be derived from various projections in the same way as using a Theodolite.
The Angles measured from two or more 360° Panoramas can be used to derive Measurements and Co-ordinates.

Front Nodal Point of a Sigma 8mm Lens   Finding the Nodal Point of a Lens  
For a lens to be used effectively for Photographic Intersection and taking certain types of Panoramas, such as full 360° Panoramas, the location of the Nodal Point (or more correctly, the Entrance Pupil) must be accurately determined.

Determination of the No Parallax Point or Nodal Point of a Lens Using a Laser   Determination of the No Parallax Point of a Lens Using a Laser
When the laser beam travels along the path of a ray that meets the No Parallax Point (NPP) or Nodal Point of a lens system, a very bright spot is seen on a surface (white card) placed behind the lens and the ray can then be drawn onto the paper. These rays can be constructed for a variety of angles of incidence and the NPP determined.
  Determination of the No Parallax Point of a Lens Using Pins & Tape Measure
This method uses the location of ‘pins’ registered with the points on a ‘tape measure’ they cover to construct the rays back to the lens position.

Cracking Nuts   Cracking Nuts
Cracking Nuts – they are absolutely passionate about nuts, natural ingredients and North Devon!
Cracking Nuts was born in early Spring in 2014 after it struck them just how moorish and tasty the humble nut can be.
They have found a 200 year old German recipe and by experimenting with it a little have come up with a traditional range of sweet cinnamon, salty and chilli roasted peanuts, cashews and almonds, all with our own unique modern twist.
