The World’s Best Data

 

Geospatial professionals need their satellite data pre-processed differently depending upon how they plan to use it, which is why we offer so many different image product options. If you have knowledge of remote sensing and are interested in our product parameters, you will find them detailed below. But if you are new to satellite imagery, get in touch with our friendly customer support team and they will help you choose the right product.

Precise Georeferencing

Most of our images are georeferenced to within 5 m of their actual location.*

More Spectral Bands

We use satellites that detect wavelengths between 450 nm and 2273 nm.

Higher Resolution

Pan sharpened images up to 30 cm resolution without any resampling.

Pixel Resolution

The pixel resolution of a satellite image defines how far you can “zoom in” on it, and how small the objects are that you can see. A low resolution satellite image will be able to show you the course of a river, but a very high resolution satellite image will be able to zoom right in on the leisure boat cruising along it.

European Space Imaging is able to supply the highest resolution satellite images available. Each each pixel in one of our 30 cm images captures an area on the ground of 30 x 30 cm, which makes smaller objects clearly visible.

This image of the Port of Valletta in Malta was captured by WorldView-4, and it has been produced in the six different resolutions that European Space Imaging offers. Each image is 600 pixels wide and high, and reproduced here at 100%. You can see the difference in detail as the resolution increases. Keep your eye on the small brown thing in the center of the image, and at the higher resolutions you can see what it is, and that it’s one of a pair!

Ortho ready imagery

Ortho ready imagery is our most popular product, and is perfect for users who want to do their own orthorectification. Ortho ready imagery is projected to a plane using map projections and datum; radiometric and sensor corrections are also applied. Geometric corrections project the image to a constant base elevation, which is calculated on the average terrain elevation per order polygon, or can be supplied by the customer.

Ortho ready imagery can be ordered directly from the archive, or can be freshly acquired by a satellite to your exact project specifications. Your image file will be accompanied by the relevant image support data files, including all the relevant metadata and shape files.

Please note that if your order is collected by the satellite in more than one strip one product will be delivered per scene.

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. They 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

Orthorectified imagery can be ordered directly from the archive, or freshly acquired by a satellite to your exact project specifications. Your image file will be accompanied by the relevant image support data files, including all the relevant metadata and shape files.

Stereo Imagery

Stereo imagery enables users to generate their own digital elevation models (DEM), create 3D visualisations, and accurately extract features. Stereo products are collected during the same orbit and acquired at angles optimal for stereo viewing and manipulation.

It has a high three-dimensional accuracy, resolution, and a large swath size. This enables more accurate mapping, terrain modeling results, and helps to alleviate feature identification issues caused by shadows or snow.

The vast majority of our clients order ortho ready stereo imagery, which has radiometric, sensor, and geometric corrections applied. Basic imagery is also available upon request.

Stereo imagery can be ordered directly from the archive, or can be freshly acquired by a satellite to your exact project specifications. Your image file will be accompanied by the relevant image support data files, including all the relevant metadata and shape files.
