#1: Looking North

(visited by Henk Pouwels)

12-Aug-2015 -- Driving from 46°N 4°E, visited this morning, was easy: just follow the commands of the navigation system of the car for about 100 km. To enjoy the landscape I avoided the autoroute (highway) and drove mainly the N7. Staring at Roanne I crossed the river Loire and close to Villefranche-sur-Saône I crossed the river Saône. Some km’s before I made a number of pictures of which I constructed a panoramic view of the landscape.

I reached the confluence from the Southwest, leaving the D904 between Lapeyrouse and Villars-les-Dombes by the C6, which goes straight to the DCP. Along this road I saw several lakes and later on I found a lot more. At home I saw that an area of about 30 km diameter is really crowded with lakes. From internet I learned that the lakes are ponds for growing fish. When it is fish harvesting time the ponds are drained and the next year they are used for agriculture.

The DCP is on private land, so the picture is taken from the road at 40 m distance. The North, East, South and West images are taken from a crossroad just 50 m from the DCP. In the West looking image the DCP is at the left; the castle is called La Grange, which is French for barn, an understatement.

In July/August France suffered from high temperatures and lack of rain. The collection of plants shows in the right corner a field of corn; normally corn is man-high this time of the year. The left corner is a typical wetland vegetation.

During this day I detected two times an error of my GPS. The reading (left top) gives the co-ordinate and a distance of 4 m to the DCP, which is in error. The correct value is 40 m. During DCP hunting I have the car-navigation and my handheld GPS side by side; it is interesting to notice the differences in guidance, but both should give the same position. Driving alongside a canal, which I had been driving the day before (blue recording), I saw the GPS deviate, trying to tell me I was on the other side of the canal (purple recording). It didn’t recover; finally I stopped the car, switched off and restarted the GPS and continued without problems. The two Streetview images (by GoogleEarth) show the North- and Southview from the position marked with Fout (Dutch for Fault), the yellow line is the road according to GoogleEarth, the blue and purple lines are the visualised tracks recorded by my GPS.
