Multigrid

From Intamap

The issue was raised by Dionisis and Ulrich: could (and should) we work with prediction grids that have a grid size that adjusts itself depending on the density of the monitoring network? Please add arguments why, or why not.

In favour

• the estimation errors may be more even (as spatial aggregation compensates for monitoring network density)
• reduced size of gridded files (where GIS permit) and computational savings too

Against

• complicated
• uneven spatial support
• you would have to draw lines around each grid cell to accentuate its size
• not many exisiting GIS support multigrid
• GML3.1 only supports regular grids: we'd need to extend GML definition of grids to work in our Web Feature Service
