Landscape

Much has been made recently in the national press of the tremendous rise in real-estate prices and of course, its effect on Cornwall. But, what is generally overlooked with this economic change is its effect on the landscape as changes in use of the Cornish landscape occur. Farmers may cease to use fields, either by economic circumstances or to be sold for development, planning departments may begin a dangerous precedent by gently opening an area to new construction, and Mother Nature herself may even inflict change.

In the current controversy regarding the conversion of the Great Crugmeer farm buildings, which lie deep within an Area of Outstanding Natural Beauty (the
Bedruthan-Padstow AONB - for a detailed map, which requires Adobe Reader, click here - AONB), this question is not only of its effect on Crugmeer, but the landscape around it. The North Cornwall District Council approved the opening of a local farm shop along the narrow, single track lane that leads from the B3276 to Steppers Point and Hawkers Cove. While the diversification of farms is a key issue, and the development of new income streams is important, did NCDC properly consider the prime directive of planning policy ENV1 in reference to AONB, which states that any development should be of "national importance"? And by doing so, have they laid the groundwork now for the continued development of what can only be called a "strip" development of the Crugmeer lane within the AONB?  The Crugmeer Society has resorted to very high tech ways of showing not only the local and regional government, but the world, exactly what it means when landscapes change, and when growth may be having more effect on the landscape than the average taxpayer knows.

Below are landscape "change detection" satellite images, generated from image data provided by NASA, the U.S. Geological Society, the Global Land Change Facility at the University of Maryland/Goddard Space Flight Centre and Jet Propulsion Laboratory. The analyses were performed by the FSC of Scotland and identical to those specified by the UN and Kyoto Treaty protocols. Unlike "Google Earth"®, which is merely satellite data that provides a "pretty postcard" view of the Earth, the analyses show how much the landscape around Crugmeer have changed between 1989 and 2003. The first analysis is focused on vegetation, shrubs and grasses, the second on change in the waters, and the third on changes in vegetation and soil. Any area in RED is a changed portion of either the vegetation, water or soil of the Crugmeer area, whether by human or natural means (but most likely human). The data is from Path 204, Row 025 of the 2003 LANDSAT 7 ETM+ satellite, and the 1989 LANDSAT Thematic Mapper satellite. The LANDSAT program is the world's oldest and only continous environmental satellite programme, having been begun in 1972. It is the accepted baseline system for every world body performing environmental monitoring. For further information on how these images were produced, please visit

Finally, just to bring home to all those interested in keeping Cornwall beautiful, clicking on any of the images below will deliver a satellite analysis image of the same type as the Crugmeer image for ALL of Cornwall. Its a beautiful world out there - lets try and keep as much of it that way as we can (oh, and here's where Crugmeer "is" at multimap.com.)

ITS HERE!!! 5 FEB 2007 - HIGH RESOLUTION IMAGERY OF CRUGMEER! CLICK ON LOW RESOLUTION IMAGE BELOW TO SEE CRUGMEER !!!




Vegetation change 1989-2003

Crugmeer, Trevone and Padstow - Vegetation, shrub and grasses change (all areas in green or blue have seen little or NO change in use since 1989. Areas in RED have seen change, or may be temporary effects such as clouds, or tidal changes (example: the sands exposed at low tide in the Camel Estuary to the east of Padstown. Developed from Band 5 information of LANDSAT 7 ETM+ and LANDSAT Thematic Mapper. Click on the image to get all of Cornwall. Areas in black are roads, houses or water, which have little reflectance value back to the satellite's sensors at this wavlength.


Landscape change - water 1989-2003.

Crugmeer, Trevone and Padstow - Water change (all areas in the Camel Estuary, offshore and other areas of significant drainage).
Again, areas in RED have seen change, largely due to natural causes, as example the shifting sands of the Camel Estuary. On farm lands, pastures or other such areas, the RED may denote that they were recently irrigated or rained up during the satellite overpass. Click on the image to get all of Cornwall.


Landscape change - vegetation and soil 1989-2003

Crugmeer, Trevone and Padstow - Soil and Vegetation change (all areas where vegetation or soil use has changed). Using Band 3 information from LANDSAT 7 ETM+ and LANDSAT Thematic mapper data, this image show the landscape where soil or vegetational change has occurred to any degree of significance between 1989 and 2003. Click on the image to see analysis for ALL of Cornwall.

Want to compare this with the North Cornwall District Council GIS (Geographical Information System) map of the Crugmeer area, which outlines the special scientific, cultural, environmental and historical aspects of the landscape.? Here you go then:

(All satellite image analysis performed using ENVI 4.3 aboard a shared array mini-supercomputer ("Aquavitae") in a UNIX environment. Special thanks to the three "Dr. Bobs", still rocking far above the troposphere all these years on...all image data crunched to sound of Marvin Gaye's, "What's Going On?". Finally, thanks to our friend in the RSF who donated hi-resolution environmental imagery of Cornwall...its everybody's world out there! For his efforts, we provide a musical interlude...prepare to download Mr. Spock....here.)
