-- Workflow:
|
|
1. Convert the ESRI grid to ASCII using R:

|
|
|
|
2. Run asc2a to convert the ASCII file to a single channel rgb file:
|
|
./asc2a <infile>.asc <outfile>.rgb
|
|
|
|
3. Use your favorite image processing package to convert from rgb to png
|
|
to compress it 40x compared to the ESRI grid image and 110x compared to
|
|
the ASCII file.
