AI-GEOSTATS: modelling_dem_point
Dear member list Considering the Albedini question ,regarding the definition of the number of lags and the lag distance,ifIhave a data points(x,y coordinates and z elevation)irregularspaced, considering that in the grid data the data are associated to the centre of thecells,can I converted them into a grid without changingtheir position (x, y) and which elevation value will beconnectedwith each cell? if the data point are regular spaced the lag distance can not be defined like the distance detween two point? regardsInes
Re: AI-GEOSTATS: modelling_dem_point
Ines It isn't usually a good idea to go pushing your data to where you would like them to be. A good way to determine natural spacing is to carry out a 'nearest neighbour' analysis. If data are on a grid, the best spacing is 0.2 times grid size. This keeps single grid spacing separate from single diagonal spacing and so on.
