In ArcGIS I have used to share a shapefile (for example beach areas) by sending a package that contains different files (.shp, .shx, .prj, .cpg, .dbf, .sbn, .xml) which contains all necessary properties for the shapefile. So far everyone has been happy.
But now I got NetCDF file of average wind speed. I successfully imported it from ArcToolbox -> Multidimensional Tools -> Make NetCDF Raster Layer. From layer properties I changed the "Color ramp" to be "red to blue", so that blue color is 3 m/s and red is 8 m/s.
Now, what is the proper way to export/save that wind speed raster layer? So that I could send it by e-mail and everyone could see the same colorful picture and the "color ramp." Is GeoTIFF-format mostly used? Or is there something better for sharing raster layer?
