IceBridge DMS L0 Raw Imagery

This data set contains level zero imagery taken from the Digital Mapping System (DMS) over Antarctica and Greenland. The data were collected as part of Operation IceBridge funded aircraft survey campaigns.

Operation IceBridge products may include test flight data that are not useful for research and scientific analysis. Test flights usually occur at the beginning of campaigns. Users should read flight reports for the flights that collected any of the data they intend to use. Check IceBridge campaign Flight Reports for dates and information about test flights.

DMS is supported by the NASA Airborne Science Program. Data collection and exceptional image quality is the result of the phenomenal efforts of our field team: Robert Billings, Kent Dunwoody, Eric Fraim, Dennis Gearhart and James Jacobson. Software integration and development was provided by Dr. Haiping Su (UCSC).

2. Detailed Data Description


The data files are JPEG image format.

File and Directory Structure

Data files are on the FTP site in folders organized by year and location, for example /2009_AN_NASA/ and /2016_GR_NASA/, where AN = Antarctica, and GR = Greenland.

Sub-directories containing raw JPEG images are named by month (MM), day (DD), and year (YYYY), for example /03142013_raw/.

File Naming Convention

Files are named using the conventions shown below. File name variables are described in Table 1:



Table 1. File Naming Convention
Variable Description
YYYY Four-digit year
MM Two-digit month
DD Two-digit day
fffff Frame number (some frame numbers are 4 digits)
.JPG Indicates JPEG image file

File Size

Files range from approxmiately 1 MB to 17 MB.


The entire data set is approximately 38.9 TB.

Spatial Coverage

Spatial coverage for the IceBridge DMS campaigns includes Antarctica, Greenland, and Arctic and Antarctic sea ice.

Arctic / Greenland:
Southernmost Latitude 60° N
Northernmost Latitude: 90° N
Westernmost Longitude: 180° W
Easternmost Longitude: 180° E

Southernmost Latitude: 90° S
Northernmost Latitude: 53° S
Westernmost Longitude: 180° W
Easternmost Longitude: 180° E

Spatial Resolution

Pixel size is dependent on flight altitude and referenced DEM. Spatial resolution is 10 cm for images acquired at 1500 ft AGL.

Temporal Coverage

These data were collected beginning 16 October 2009 to 18 November 2016 as part of Operation IceBridge funded campaigns.

Temporal Resolution

IceBridge campaigns are conducted on an annual repeating basis. Arctic and Greenland campaigns are conducted during March, April, and May, and Antarctic campaigns are conducted during October and November.

Parameter or Variable

Parameter Description

The DMS Level-0 files contain 3-banded imagery.

3. Data Access and Tools

Data are available via:



Software and Tools

The image files can be opened using any software capable of displaying JPEG files.

4. Data Acquisition and Processing

Data Acquisition Methods

DMS is a visible imaging system, capturing data throughout flight. Level-0 products for raw DMS include raw JPEG files. Most imagery were acquired in panchromatic mode, but all provided output is 3-banded imagery.

Sensor or Instrument Description

The DMS airborne digital camera acquires high resolution natural color and panchromatic imagery from low and medium altitude research aircraft. The system configuration includes a 21 megapixel Canon EOS 5D Mark II digital camera, computer-controlled intervalometer, and an Applanix POS/AV precision orientation system. In-flight operators maximize image quality with adjustments to exposure and intervalometer settings.
