I'm trying to reduce the overall size of the bathymetric maps I'm creating to fit on a 32GB card. The source imagery is typically high resolution, however the majority of the areas within the map are not considered to be 'areas of interest'. I would like to create a map where I could set the majority of the map to a Minimum Resolution of 1 while displaying specific areas of interest within the map at a higher resolution like .125 or .0625. Creating the entire map with a Minimum Resolution set to .125 results in rather large file sizes and takes a long time to generate.

Is it possible to export the entire area with a Minimum Resolution of 1 then create smaller higher resolution maps of the areas of interest with a Minimum Resolution set to .125 or .0625, then combine the files from multiple at5 export onto file that represents one map with multiple levels of resolution?









Thank you.

Sorry for the late reply on this one. I think the answer, unfortunately, is no. Since you can only display a single raster map at one time, and rasters are exported as a single resolution, then the whole map will have the same resolution. It might be possible to do something with multiple raster maps, with a small area stored as a separate map with higher resolution, but I would have to look into this further.

Okay, thanks for the response.
