[ai-geostats] Estimation with minimum data

2005-06-06 Thread amazot
Dear All, Since 2001, 450 measurements of CO2 have been carried out (area of 109000 m2) to know the total output of CO2 that escapes from a volcano. I used stochastic simulation (sgsim) to map the area and to quantify the total ouput of CO2. Since 2001, the total CO2 flux has decreased. The

AI-GEOSTATS:Variogram Surface in the Software Variowin2.2

2001-09-14 Thread amazot
Hello, In the program VARIO2D with PCF in the software VARIOWIN 2.2, we need to identificate the main directions of anisotropies of the spatial behavior of a variable. For this, we use the Variogram Surface. I didn't quite understand how we use this graph for having directions of anisotropies? I
