Maxar operates a fleet of satellites that capture imagery of the Earth. Some of these satellites offered the best resolution commercially available when they were first launched into space. Last year, Maxar earned ~$1.6B largely from selling imagery these satellites produced.
I found a price list for new images taken and it stated that each KM2 of imagery costs between $25 - $44. This could end up becoming an expensive hobby but thankfully Maxar also runs an Open Data Programme. In exchange for your contact details, you can get access to over 100 imagery sets taken in areas before and after they were struck by disasters.
But for anyone unwilling to part with their contact information, there is a freely available SpatioTemporal Asset Catalog (STAC) published by Maxar that details imagery URLs and metadata for 28 disaster events. Below is a map of these locations and event details.
In this post, I'll download and examine Maxar's freely available satellite imagery.
Installing Prerequisites
The following was run on Ubuntu for Windows which is based on Ubuntu 20.04 LTS. The system is powered by an Intel Core i5 4670K running at 3.40 GHz and has 32 GB of RAM. The primary partition is a 2 TB Samsung 870 QVO SSD which will host the applications used in this post. The images will live on an 8 TB mechanical drive.
I'll be using GDAL and Python to help analyse the images in this post.
$ sudo apt update
$ sudo apt install \
gdal-bin \
jq \
libtiff-tools \
python3-pip \
python3-virtualenv
I'll set up a Python Virtual Environment and install a few packages.
$ virtualenv ~/.maxar
$ source ~/.maxar/bin/activate
$ python -m pip install \
rich \
shapely \
typer
I'll also use DuckDB, along with its JSON and Spatial extensions, in this post.
$ cd ~
$ wget -c https://github.com/duckdb/duckdb/releases/download/v0.9.1/duckdb_cli-linux-amd64.zip
$ unzip -j duckdb_cli-linux-amd64.zip
$ chmod +x duckdb
$ ~/duckdb
INSTALL json;
INSTALL spatial;
I'll set up DuckDB to load all these extensions each time it launches.
$ vi ~/.duckdbrc
.timer on
.width 180
LOAD json;
LOAD spatial;
The maps in this post were rendered with QGIS version 3.34. QGIS is a desktop application that runs on Windows, macOS and Linux.
I used QGIS' Tile+ plugin to add Esri's World Imagery Basemap to each of the map renderings. This basemap helps provide visual context around Maxar's imagery.
Downloading Satellite Imagery
Qiusheng Wu, an Associate Professor at the University of Tennessee manages a GitHub repository that contains metadata and manifests for the 28 image sets Maxar has made freely available. I'll clone this repo on my mechanical drive and create a downloads folder for the imagery.
$ git clone https://github.com/opengeos/maxar-open-data/
$ cd maxar-open-data
$ mkdir -p downloads
I've put together a script that will download all of the 'visual' images from Maxar's datasets. It contains a progress bar to give you an idea of how long the whole process will take.
If this script fails, it can be run again and it won't re-download any existing images, only ones not yet downloaded.
It will skip past certain errors and when the script has finished, you can run it again to re-try those URLs it wasn't able to download from already.
If new datasets are published, you can run git pull to get the new metadata and manifests and then run the download script again.

The following naming convention was used for the images.

Cloud-Optimised GeoTIFFs
The TIFF files Maxar delivers are Cloud-Optimised GeoTIFF containers. The files contain Tiled Multi-Resolution TIFFs / Tiled Pyramid TIFFs. This means there are several versions of the same image at different resolutions within the TIFF file.
These files are structured so it's easy to only read a portion of a file for any one resolution you're interested in. A file might be 100 MB but a JavaScript-based Web Application might only need to download 2 MB of data from that file in order to render its lowest resolution.
Below I'll write a parser to convert the output from tiffinfo into JSON.
$ vi json_tiff.py
import json
import re
import sys
stack, stack_id = {}, None
for line in sys.stdin.read().splitlines():
if not stack_id:
stack_id = 1
elif line.startswith('TIFF Directory'):
stack_id = stack_id + 1
elif line.startswith(' ') and line.count(':') == 1:
if stack_id not in stack.keys():
stack[stack_id] = {'stack_num': stack_id}
x, y = line.strip().split(':')
if len(x) > 1 and not x.startswith('Tag ') and y and len(str(y).strip()) > 1:
stack[stack_id][x.strip()] = y.strip()
elif line.startswith(' ') and line.count(':') == 2 and 'Image Width' in line:
if stack_id not in stack.keys():
stack[stack_id] = {'stack_num': stack_id}
_, width, _, _, _ = re.split('([0-9]*)', line)
stack[stack_id]['width'] = int(width.strip())
print(json.dumps([y for x, y in stack.items()], indent=4, sort_keys=True))
The following will produce a JSON file with the metadata of one of Maxar's TIFFs.
$ tiffinfo -i downloads/BayofBengal-Cyclone-Mocha-May-23/2023-01-03/ard_46_033113111121_2023-01-03_104001007EBB7C00-visual.tif \

Within the TIFF, the original JPEG's image width is 17,408 pixels wide. There are 6 subsequent images each roughly half the width of their parent image. There is also an alpha channel with 6 alternative widths as well.
Maxar's Satellite Fleet
Four of Maxar's Satellites have provided the imagery available in these image sets. Every image's metadata contains the platform / satellite name used to take the photo.
GeoEye-1 (GE01) was built by General Dynamics and launched by Boeing in 2008. It was expected to run for 7 years but it is still running to this day, 15 years later. It's located 673 KM above the Earth's surface and can capture 41 cm panchromatic imagery and 165 cm multispectral imagery.
WorldView-2 (WV02) was built by Ball Aerospace and launched by Boeing in 2009. It was expected to run for ~7 years but it is still running to this day, 14 years later. It's located 772 KM above the Earth's surface and can capture 46 cm panchromatic imagery and 184 cm eight-band multispectral imagery. It can take a photograph of anywhere on early every 1.1 days. This satellite was hit by space debris in 2016 but Maxar deemed the damage to be minimal.
WorldView-3 (WV03) was built by Ball Aerospace and launched by Lockheed Martin in 2014. It was expected to run for ~7 years but it is still running to this day, 9 years later. It's located 619 KM above the Earth's surface and can capture 31 cm panchromatic imagery, 124 cm eight-band multispectral imagery, 370 cm short wave infrared imagery and 3000 cm CAVIS (Clouds, Aerosols, Vapors, Ice, and Snow) data imagery. This satellite took a photo of the Landsat 8 satellite last year.
WorldView-4 (WV04) was built by Lockheed Martin and launched in 2016. In 2019, it failed and it re-entered the Earth's Atmosphere over New Zealand in late 2021. It was located 613 KM above the Earth's surface and could capture 31 cm panchromatic imagery, 124 cm multispectral imagery, 450-800 nm panchromatic wavelengths and 450-920 nm multispectral imagery.
Imagery Metadata
Below I'll combine all of the GeoJSON files of interest within this repository into a single JSON file. I've added fields for the event name and a Well-Known Text (WKT) version of each image's footprint as well.
$ python3
from glob import glob
import json
from shapely import wkt
from shapely.geometry import shape
recs = [json.loads(open(x).read())
for x in glob('datasets/*/*.geojson')
if 'union' not in x]
out = []
for rec in recs:
for f in rec['features']:
out.append({**{x: y
for x, y in f['properties'].items()
if type(y) is not dict},
**{'event': f['properties']['visual'].split('/')[4],
'geom': wkt.dumps(shape(f['geometry']),
rounding_precision=6)}})
open('aggregate.json', 'w').write(json.dumps(out))
The above produced a 23,171-record, 20 MB JSON file. Below is the first record from the JSON file.

There are cloud cover measurements for each image. There could be many images of the same area and sometimes this can be a handy value to help pick which imagery to work with.
"Off Nadir" is the satellite's angle in relation to the ground. The larger the angle, the more pixels get stretched so there is a relationship between this value and how useable the resulting image is.
Azimuth / direction and elevation indicate the satellite's position above the ground.
The incidence angle is calculated from the target position on the ground looking at the direction of the satellite in the sky. This value combines the pitch and roll angles.
Below I've cherry-picked some images taken at the same time next to one another and applied heatmaps to these values.
Below is the average cloud cover percentage by satellite by year. Maxar does a good job of sourcing near-cloudless images of areas prior to their respective disaster events.

Within any one event's dataset, there can be imagery from multiple years and multiple satellites. The Moroccan dataset is 386 GB and has 8,700 images taken by four satellites at different times over a 13-year period.
Below I've coloured the image footprints by year using the following expression in QGIS.
ramp_color('Wiener Challah', (2023 - to_int(substr("datetime", 1, 4))) / 13)
Multiple satellites could provide imagery over a short period of time as well. Below both WorldView-02 and WorldView-03 imagery were sourced for New Zealand with the images taken a few weeks apart from one another. The outlines are labelled with the abbreviations for their respective satellites and for clarity, the satellite imagery basemap is from Esri, not Maxar.

I'll drop the image onto a new QGIS workspace and outline it in yellow to differentiate it from the Esri World Imagery Basemap surrounding it. I've also imported polygons from OSM for this area as well. I've colour coded and labelled the polygons by their landuse field.
Below is the image at 100% zoom. There is good visibility of cars and buildings on the ground and a lot could be inferred from imagery at this resolution.
