AI-GEOSTATS: choosing grid resolution

2011-03-14 Thread Raul Sierra Alcocer
Dear list, I am a PhD student in Computer Science new to spatial analysis, and I am working in a data mining platform at my institute that will provide some tools for spatial data mining. It is basically analysis of spatial features using rectangular grids. My question is if there are any studies

Dear Raul, Any changes in the size {GSsupport/GS}, shape {GSanisotropy/GS} etc of cells (grids) in cell-based analysis including from spatial analysis (GIS etc) and geostatistics (grided variogram, kriging etc) need to be considered carefully while they can provide very different correlation

There is also a fair amount of literature on the Modifiable Areal Unit Problem (MAUP) that goes back for several decades. The role of spatial scale in the analysis can be a critical one with not only changes in cell size but also rotations, etc., applied
