this is great and that's what i love so much in GE-panoramio link: exact geographic location of the picture. This makes it more real , and shows an aspect of our plant in the time. very nice job, Ian. Artistic and informative! thanks to you Annick
Beautiful picture. Why is that in circels ???
Yes Annick, that's the genius of Panoramio. I remember my first venture onto GE when my cousin was travelling the Silk Road and I wanted to see where he was going on the GE imagery and found the pictures uploaded through Panoramio. What an expensive time of download followed, for I was captivated and I just couldn't get out of Turkey until the travellers moved east. Then I began to look at familiar places and discovered GE was just waiting for me to get the camera out.
And now we have this talkative and appreciative net-community to share with. Thankyou for your photos shared and for your conversations.
1. These cirles are an efficient way of irrigating - the farmer has a system that pumps water into a boom the length of the radius and this radial boom then moves around the huge paddock like the hand on a clock - the boom having wheels on legs that allows the boom to pass above the crop. The amount of water that is released is callibrated so that more water is released near the perimeter than near the centre. This system saves the farmer having to move pipes or sprays around the paddock, which one farmer could not accomplish on this scale.
There are other circular patterns in this landscape as well:
2. Water is harvested from overland flows and stored in ring tanks about the same size as this paddock (they can be much smaller or much larger). A circle holds a greater volume in proportion to the length of bund or wall that has to be constructed, though as they get larger they are mostly rectilinear.
3. As depicted in another image in this set, deflation hollows are circular too, as this is a clay plain that has historically received winds from variable directions.
Hope all this is interesting to you.
Kind regards, Ian
Thanks Ian, all your explenations are of great interest! an Panoramio-GE is the best way to discover places where you have friends who travel or live overthere!
I am fascinated by these geometrical photos, Ian! Thank you for the interesting information!
It is wonderful to be involved with such an appreciative network of photographic artists. Annick, Evangelos and May, thankyou each for your artistry shared as well as your encouragement. Ian
I just relocated my photopoint, for this view is looking north. These circular fields are clear on a larger scale on GE. If you were to scan the GE you will see other circular fields a few kms further south-west.
The fields to the SW are irrigated from water stored in a large oxbow lake (or large meander now cut-off from the main channel) of the Balonne River. The old meander has recently filled as a result of a small flood in the river and consequent discharge from Lake Kajarabie (Beardmore Dam). Right now the farmers are all out cultivating to capitalise on the wet paddocks and water allocations. Sorghum and sunflowers are the principal crops being planted, for their mainstay crop, cotton needs a longer season than is now available. (It has to be in the ground by November.)
Thank you Ian for all these details. Unfortunately I can't get on GE, not even on the little map beside the photo. Both my computers only work partly. I will have to manage like this until I get a new one. But I am reading your infos with interest!
I appreciate your comment, arsène & lupin. Thanks. The inland plains are rather endless.
