I am a food system researcher and doctoral student at Tufts University in the Agriculture, Food and Environment and Water Diplomacy Programs. My research seeks to advance a transition towards resilient food production and distribution systems by leveraging computational modeling and data visualization.

comment mosaic raster to file geodatabase yields missing raster sections
@radek, I use tiff format for the image and file geodatabases, but I suspect other formats will work as well.

@radek, never got this fixed. I think that I just put up with writing to a system folder and then copying into the gdb.

comment why is map tiling computationally intensive?
I accept that the compression/decompression process makes it quite difficult. However my disk monitoring doesn't suggest that its incredibly I/O intensive. In any case, I gather that uncompressed input data is probably better to use, right?
