SENSORVIEW Since the launch of the first Very High Resolution commercial satellite, European Space Imaging has been providing the best possible spatial resolution to the European market. From our inception in 2002, we have established and maintained strong relationships with the industries premium satellite imagery leaders and this has allowed us to ensure that we stay at the forefront of the geospatial industry. Through our long-standing partnership with Maxar Technologies, we have direct access to the WorldView constellation, the World’s best satellites in terms of spatial resolution. From our ground station at the German Aerospace Center (DLR) our expert operations staff directly access the satellites as they pass over Europe and North Africa. Utilising optimised and flexible collection planning, we can confidently guarantee the best possible image in terms of clarity, and always with 15% cloud cover or less. The WorldView constellation collects over 3 million square kilometres of data per day and can cover approximately 60% of the Earth’s surface monthly with intraday revisits. Expanding our satellite portfolio to extend beyond just that of Very High Resolution, we entered into a partnership with Satellogic in 2020 and have access to their entire satellite portfolio, including their Aleph-1 constellation, delivering up to 0.7 m and beyond spatial resolution satellite imagery in both multispectral and hyperspectral. The Aleph-1 constellation can collect more than 4 million square kilometres per day and has a revisit rate of up to 4 times per day. Through these innovative partnerships, European Space Imaging now has access to 25 orbiting satellites at resolutions of 30 cm – 1 m and with a combined daily revisit of close to 10 times per day. In addition, we have access to an extensive imagery archive incorporating billions of square kilometres of dating from all over the world dating back as far as 2000.

It has the ability to cut through haze and thereby improves image quality, clarity and usability. 15 cm HD 15 cm HD is achieved through a process that intelligently increases the number of pixels in a native 30 cm resolution image, resulting in an improved visual experience. Analysts and machines can then utilise 15 cm HD imagery to better extract features and meaningful information. Not limited to any certain resolution, HD technology can also be applied to native 40-60 cm imagery, rendering a 30 cm HD image and thus, increasing the availability of 30 cm resolution imagery across the historical archive. Standard Imagery Standard Imagery products are suitable for users requiring modest absolute accuracy and/ or large area coverage. These products are radiometrically corrected, sensor corrected, and projected to a plane using the map projection and datum of the users choice. The radiometric corrections applied to this product include: relative radiometric response between detectors, non-responsive detector fill, and a conversion for absolute radiometry. The sensor corrections account for internal detector geometry, optical distortion, scan distortion, any line-rate variations, and registration of the panchromatic and multispectral bands. Geometric corrections remove spacecraft orbit position and attitude uncertainty, Earth rotation and curvature, and panoramic distortion. Standard Imagery comes in two varieties: • View Ready (2A) Imagery: Standard Imagery has a coarse DEM applied to it, which is used to normalize for topographic relief with respect to the reference ellipsoid. The degree of normalization is relatively small, so while this product has terrain corrections, it is not considered orthorectified. • Ortho Ready Standard (OR2A) Imagery: Ortho Ready Standard Imagery has no topographic relief applied with respect to the reference ellipsoid, making it suitable for orthorectification. Ortho Ready Standard Imagery is projected to a constant base elevation, which is calculated on the average terrain elevation per order polygon or can be supplied by the customer. IMAGERY TYPES & PROCESSING METHODS Orthorectified Imagery Orthorectified imagery is fully processed and ready to be integrated into your GIS workflow. Orthrectified images provide a perfect base for creating and revising mapping and GIS databases or for registering existing feature layers. It can be used for change detection and other analytical applications that require a high degree of absolute accuracy. It comes with all the geolocation information applied, including the refined ephemeris, attitude, rotation, terrain elevation, and alignment to the map projection. Multiple images can be mosaicked to minimize seamlines, and tonal balancing can be applied if desired. It is available in two different accuracy specifications: Mapping: No ground control points Precision: With ground control points Basic Stereo Pair Imagery Products Basic Stereo Pair Imagery products are suitable for customers with a high level of image expertise and who have software that is capable of ingesting, processing, and/or displaying stereo imagery. Basic Stereo Pair Imagery products are typically used to create Digital Elevation Models (DEMs) or for three-dimensional feature extraction. Basic Stereo Pair Imagery products are comprised of one or more pairs of Basic Images with 100% overlap over the customer’s Area of Interest (AOI). Stereo mates are collected on the same satellite orbit and with specific look angles in order to attain imagery appropriate for stereo viewing. Basic Stereo Imagery is available in Panchromatic, 4-band Multispectral, or Pan + 4-band Multispectral Products. Ortho Ready Stereo Imagery Products Ortho Ready Standard Stereo Imagery products are suitable for customers with a high level of image expertise and software that is capable of ingesting, processing and/or displaying stereo imagery. They are typically used to create Digital Elevation Models (DEMs) or for three dimensional feature extraction. Customers ordering stereo products who require a small area of interest (AOI) should order the Ortho Ready Standard Stereo Product while customers requiring large area coverage should opt for the Basic Stereo Product. Ortho Ready Stereo Imagery is map projected but has no topographic relief applied with respect to the reference ellipsoid, making it suitable for orthorectification. Ortho Ready Stereo Imagery is projected to a constant base elevation, which is calculated on the average terrain elevation per order polygon or can be supplied by the customer.
