GNIS provides satellite imagery from a wide range of Electro Optical (EO) sources, providing options to address almost any imagery need or requirement. Imagery is available in a range of spatial resolutions from 30cm to 22m. All of the satellites collect imagery in both the visible (RGB) and near inferred (NIR), in additional several of the satellite can also collect the short wave inferred (SWIR) bands. This breadth of spectral options, allows GNIS to satisfy a range of users from those interested in simply seeing a ‘picture’ to those performing advanced analysis. Furthermore, GNIS can acquire new imagery anywhere in the world and provide historical imagery back to 1986.
Synthetic Aperture Radar (SAR) imagery can be acquired day or night, and in all weather conditions, making it an ideal solution when there is an urgent need for new imagery anywhere in the world. Available in resolution ranging from 25cm to 40m, SAR data can support a diverse range of applications from highly detailed site mapping/monitoring to monitoring maritime activity or hazards over a large swath of the ocean. Moreover, the active nature of a SAR technologies provide some unique processing capabilities, which include the ability to monitor movement on the earth’s surface to the millimeter level.
Produced from satellite imagery (EO & SAR) sources, GNIS provides a variety of Digital Elevation Models (DEMs) to support a broad range of applications. Both Digital Surface Models (DSM) and Digital Terrain Models (DTMs) are available at post spacing of 1-30m. One highlight is WorldDEM, the first and only truly global high-resolution DEM. WorldDEM is an off-the-shelf product that can be produced to specifications and delivered within a few days*. Other elevation products are built-to-order, some requiring new data acquisition and others using archive data.

GNIS offers a wide range of GIS-ready mapping products, many with off-the-shelf availability. We also offer value-added image processing services for build-to-order mapping products.
Many users lack the expertise, software or time required to transform raw satellite imagery into useful products. This can be as straight forward as creating an ortho-rectified image so the imagery can be easily integrated into a GIS or CAD applications, to expert analysis of satellite imagery used in the development of a geological study over a region. Using in-house experts and the expertise of key partners, GNIS can delivery virtually any type of imagery-derived product.
GNIS, in partnership with customers and partners, can design custom satellite-based programs to support site monitoring and emergency response services, for any location in the world. Programs can include the collection, processing, and analysis of imagery, along with reports tailored to customer needs.
In addition to image acquisition and processing, GNIS also provides geospatial content hosting and management, along with web service delivery. This solution can be fully cloud-based or deployed as an appliance behind the firewall.
