A simple GlobalMapper script that iterates through all the tiff files in a specified directory, and exports them to ecw in EPSG 2180, 3857 and 4326.

//Exports all the tif files found in the source dir to ecw.
//Reprojects the data to 2180, 3857 and 4326 and the exports it to the appropriate folders

GLOBAL_MAPPER_SCRIPT VERSION=1.00

//Define in / out folders
DEFINE_VAR NAME=source_dir VALUE="C:\here\goes\input\path"
DEFINE_VAR NAME=target_dir VALUE="C:\here\goes\output\path"

//start the loop to iterate through all the files

	//Import the file
	IMPORT FILENAME="%FNAME_W_DIR%"

// End the loop

per file:

gdalwarp -t_srs "EPSG:4326" input.tif output.tif

and a batch:

@echo off
mkdir processed
for %%F in (*.tif) do (
	echo processing %%F
	gdalwarp -t_srs "EPSG:4326" %%F processed\%%F
)
pause
