Geospatial Insight is the UK reseller for satellite imagery from the following providers:
Providing high quality Earth Observation (EO) data since the launch of Spot-1 in 1986, Airbus operates a fleet of optical and radar EO satellites. As their partner, Geospatial Insight can provide its clients with imagery from a range of satellites, including Pléiades. The Pléiades 1A and Pléiades 1B satellites operate as a constellation in the same orbit, phased 180° apart. The identical twin satellites deliver very-high-resolution optical data products with an unrivalled reliability when it comes to collecting a new image. Key technical capabilities are summarised below:

Pleiades provides imagery which is optimised for precision mapping and in-depth intelligence gathering, and is particularly suitable for emergency response and up-to-daily change detection.
Radar imagery and 3D terrain data are accessed from the TerraSAR-X (2007) and TanDEM-X (2010) satellites offering a range of different resolutions, swath width and products. TerraSAR-X and its TanDEM-X twin fly in formation just a few hundred metres apart. They will soon be joined by the Spanish satellite PAZ, a third clone. All three satellites reliably acquire the widest range of radar images, from the highest resolution to very wide coverage – regardless of weather and day light conditions. Versatile and flexible, TerraSAR can collect vast areas in one image or acquire very high resolution images (25 cm resolution) of specific targets. TerraSAR provides a reliable and timely acquisition capacity, with daily revisit in most latitudes. Geolocation accuracy is excellent without the need for ground control.

Planet Labs (including RapidEye Data)
Leading a paradigm shift in access to EO imagery, Planet Labs has rapidly created an unrivalled constellation of nano satellites. Founded in 2010 by a team of ex-NASA scientists, Planet Labs objective is to create a constellation of satellites, and supporting infrastructure, to image the entire Earth every day, and to provide wide access to that data.
Two years after the first Planet Labs “Dove” satellite entered space, Planet have launched more than 100 of these satellites, and now operates the largest constellation of Earth-imaging satellites, with more than 40 satellites currently in orbit. Many more launches are scheduled for launch, including a launch of 32 satellites in April 2016, and the objective is to deploy and maintain a constellation of 150 satellites, providing daily images of each point on the Earth’s surface by the end of 2016.
The Dove micro-satellites are in the 4kg-class and operate in both near-polar, sun-synchronous orbit and in an ISS-like orbit (i.e. between 51.6 degrees north of the equator
and 51.6 degrees south of the equator), which is not surprising since to date most Planet satellites have been launched from the ISS.
Planet Labs data is available at a range of GSD’s between 3.7-5m, depending upon the satellite generation (the satellites and sensors are being constantly developed based on in-orbit testing and refinement of that experience – the current variant is the 13th since the launch of the first satellites in 2013) and orbit.
Data available today is RGB only (Red: 0.61–0.70 µm, Green: 0.50–0.59 µm, Blue: 0.42–0.53 µm), although Near Infrared imagery has been acquired and is planned for future launches.
Tasking is not possible with Planet Labs satellites, as the whole concept is based around near-continuous monitoring of all the Earth’s surface on a frequent (daily) basis.
Raw and processed data is made available, via an API, soon after acquisition via the Scene Explorer and Mosaic Explorer platforms. This approach is radically different to traditional means of accessing the data. For example, GSI have built a link to the API which allows a user to specify a number of Areas of Interest (AOI), and any Planet data acquired of those areas are automatically analysed for cloud cover, downloaded (if suitable) and then any gross change from the previous image is automatically detected and highlighted. Also, the Mosaic Explorer platform can use innovative, automated Pixel Compositor methodology to create a new type of “dynamic” mosaic , By algorithmically selecting the best pixel for any given location, mosaics can be quickly and accurately generated without further human input, composed only of the most up-to-date pixels. Full traceability of the actual images used is provided, allowing monthly and weekly composites to be created, with knowledge that the mosaic was only built from scenes in that period.
Highly cost-effective, Planet Labs enables entirely new monitoring solutions to be developed – at a relatively low resolution but at a very high temporal frequency, and with a high level of automation.
In addition, Planet Labs now owns and operates the Rapideye constellation. First launched in 2008, this constellation of five identical satellites has been operating successfully since early 2009. Capable of collecting 5 million sq km daily, the constellation is optimised provide large area coverage over a short period of time. Key characteristics of the RapidEye constellation and data it generates can be summarised as follows:

• Cloud-free imagery whenever possible (always less than 3%)
• The most current high-resolution mosaics available, with narrow acquisition windows
• Off-the-shelf or custom-made options
Urthecast (including Deimos Data)
Following the purchase of the Deimos satellite business, Urthecast can offer a unique blend of EO data to the user community, combining data from the proven Deimos-1 (22m, 660km swath, launched 2009) and Deimos-2 (1m, 12km swath, launched 2014) satellites with radical new imagery options created from the MRC Theia sensor and HRC Iris high-resolution video camera, both mounted on the International Space Station (ISS).
Deimos-2 provides 1.0 m resolution imagery for the Panchromatic channel and 4.0 m for the four Multispectral channels (Blue, Green, Red, Near Infra-red). With an average global revisit time of two days, Deimos-2 can provide high quality monitoring services which are very flexible – new targets can be tasked in less than 24 hours and the data, once acquired, delivered from satellite to user in less than 3 hours.
The unique High-Resolution Iris (HRC) video camera is mounted on a Bi-axial Pointing Platform (BPP) on the ISS and captures 1m-class, Ultra High-Definition (UHD) full-colour videos. These are made available as image stacks and videos, and can provide up to 90 seconds of “staring” video imagery of an event.
Beijing Space Eye International
Through its relationship with Beijing Space Eye (BSEI) Geospatial Insight can access data produced by a number of highly capable Chinese government satellite missions such as the TH-1 series (2m, 60km swath, launched 2010/2012/2015), ZY-3 (2m, 51km swath, launched 2012), GF-1 (2m, 70km swath, launched 2013) and GF-2 (0.8m, 45km swath, launched 2014). Substantial archives exist for all these satellites, and together they provide a powerful, cost-effective new addition to the mainstream of commercial Earth Observation resources.
Geospatial Insight are a reseller of data from the EROS-A (2m, 15km swath width, launched 2000) and EROS-B (0.7m, 7km swath width, launched 2006) satellites, operated by our partner, Imagesat International. Both satellites produce very high quality panchromatic imagery, optimised for photointerpretation and mapping purposes.
