Downloading Imagery Data

What is in this directory

Each image directory contains all of the images in the dataset, a metadata file, and an index shapefile that shows the location of each image in the dataset.

Directories may contain over a thousand files, so users will generally want a mechanism that allows downloading in bulk. One option is to use Wget (freely available at http://www.gnu.org/software/wget/), a command line utility that is very flexible and works on multiple platforms. An example usage of Wget is given below.  Other options are available, and a Web search for "download manager" should provide some useful results. Please note that the files are most easily accessed via ftp at https://coast.noaa.gov/htdata/raster1/imagery or at https://coast.noaa.gov/htdata/raster2/imagery.

Displaying Imagery Data

Some imagery viewers may apply a 2 standard deviation stretch on the imagery by default. This may result in urban features appearing bright or "washed out". Turning off the 2 standard deviation stretch should correct the problem.
