Uses of nighttime satellite imaging:Nighttime satellite imagery is created by detecting emissions from human activity on the planet, including infrastructure (city lights, villages, towns, industrial and agricultural facilities, mining, gas flares, fishing vessels, etc.) and natural lights such as fires, lightning, moonlight, microorganisms, and animals.
Satellite images of nighttime lighting have been used for decades as a global data source to study a wide range of socio-economic factors.
Nighttime imagery of the Earth has a wide range of applications in the following areas:
- Defense and reconnaissance.
- Protection of national borders.
- Economic development and infrastructure.
- Energy sector. Malfunctions and outages.
- Distribution and population density of cities and rural areas.
- Night search and rescue operations during emergencies. Fire outbreaks. Gas leaks.
- Vessel detection.
- Fishing industry.
- Light pollution monitoring.
- Analysis of urban areas' illumination and growth. Municipal services.

Purposes and Objectives of Nighttime Satellite Imaging
The purpose of nighttime satellite imaging: to create a picture of the Earth's nighttime environment, specific regions, territories, and objects. This involves creating "night maps," photos, and video images that reflect the constant light emissions on the Earth's surface. Nighttime remote sensing data, statistics, cartographic information, and text provide access to territorial and object-based information anywhere on Earth, complementing and enhancing daytime satellite imaging.
Detailed objectives based on the purpose include real work in:
- Creating topographic maps and plans, as well as other cartographic products based on nighttime imaging data;
- Compiling thematic maps related to issues such as economic growth, poverty, and inequality, especially where data is lacking;
- Developing a geospatial index of household prosperity calculated within the framework of demographic and medical surveys, which places individual households on a continuous scale of relative prosperity from poorer to wealthier;
- Creating engineering-topographic maps for engineering-geodetic surveys using nighttime imaging;
- Evaluating the situation on the ground during specific nighttime periods, including changes over time (military tactical level, traffic on roads and railways, fishing, power supply);
- Monitoring changes on the ground using nighttime imaging over the years;
- Creating a remote sensing basis for thematic geological and infrastructure exploration maps using infrared (IR) spectrum nighttime imaging;
- Monitoring emergency situations and their consequences during nighttime, controlling and conducting emergency recovery work;
- Monitoring light pollution of the environment;
- Creating fire photomaps;
- Improving existing approaches to mapping urban areas by integrating nighttime light (NTL) data with satellite images from other satellites (Landsat, Sentinel, WorldView, JL1-3B, Aster, Modis, etc.).
Advantages of Using Nighttime Remote Sensing Satellite Data
Mid-resolution nighttime imaging data can be obtained from open sources and combined with high-resolution images (if required by the Client), acquired rapidly from Geo Innoter (resolution of 0.5 – 3 meters), specifically designed for nighttime imaging.
For nighttime monitoring, the images may already be available in the archives of the satellite operator, and new imaging does not require any approvals from governmental bodies. The coverage area of nighttime satellite images significantly exceeds the area covered by images obtained from aircraft or UAVs.
Materials acquired from aircraft or UAVs have high visual informativeness and excellent measurement properties but require a longer time for nighttime imaging, as it involves time for approval of the flight, transportation of aircraft (UAV with operators) to the imaging area, and higher (multiplicative) cost of data per 1 km2.
The resolution of nighttime satellite imagery eliminates the need to engage aircraft and UAVs in nighttime conditions, which, according to existing flight regulations, presents special and often impractical conditions.
Another undeniable advantage of satellite imaging is its objectivity (minimizing human factors).
Prices for services
The cost of execution is calculated on an individual basis, taking into account a specific of task.
After receiving the task description, we calculate the cost and send you a commercial offer.
Period of execution
The timeframe for nighttime satellite imaging depends on the following factors:
- Work execution period - from 5 (five) working days, calculated individually for each client.
- Work execution period depends on the total area of imaging, the number of processed images, and their type (mono-stereo), calculated individually for each client.
How to place an order:
- Step 1: Submit a request for nighttime satellite imaging on the website with the following information:
- Description of the task requiring the use of nighttime satellite imaging materials.
- Location of the area of interest (coordinates, name of the region, district, SHP-file, etc.).
- Requirements for the imaging period (whether archival data can be used or new imaging is required).
- Quality requirements for the imaging (mono-stereo, image tilt angles, resolution on the ground, cloud cover, sun angle, panchromatic or multispectral imaging, etc.).
- Step 2: Agreement on technical specifications and cost:
- The cost of the service is negotiated in each specific case.
- Images are paid separately (ranging from $7 to $40 USD per 1 km2 depending on the type of imaging, whether it's archival or new, and the resolution).
- Step 3: Signing the contract and commencing the work:
- The timeframe is approximately 5 working days from the date of receiving 100% advance payment for the nighttime satellite imaging materials. Payment is accepted only via non-cash transactions. The remaining payment is made after the completion of the work.
We provide services to individuals, legal entities, individual entrepreneurs, government and municipal authorities, foreign clients, etc.

Requirements for Source Data
Accurate coordinates of the area of interest, requirements for satellite imaging materials (resolution on the ground, type of imaging, maximum angle of the image, maximum allowable percentage of cloud cover, nighttime period for imaging).
If it is not possible to provide the specified information, provide information about the purpose of using remote sensing materials, and the specialists of GEO INNOTER will analyze the requirements and suggest an optimal solution to the problem
- Task to be solved using nocturnal space imagery;
- Area of interest (location / coordinates of the object in any convenient form, and the area of the object);
- Date or time interval for which archive imagery can be selected or new imagery can be obtained;
- Requirements for the imagery (angle of inclination of the image, spatial resolution, type of nocturnal imaging, cloud cover, permissibility of snow cover).
- For new imagery: If the area of work is known in advance, but imagery with the required parameters is not available in the archives of space imagery operators, and the allowable time interval for carrying out new imagery is sufficiently large to complete it in standard mode (without additional payment for expedited or priority processing), there is an option to perform speculative imagery - essentially a new imagery without any commitment to purchase. Since archival remote sensing data is cheaper than ordering new imagery, once the imagery obtained from speculative imaging is archived, it can be purchased at a reduced price. After 60 days, the price usually decreases further.
- For new and archival imagery: If the area of interest consists of multiple separate polygons that are not interconnected and each polygon's area is smaller than the minimum order size (25 km2 for archival imagery or 100 sq. km (see point 1)), it is advisable to combine them into polygons with areas larger than the minimum order size to reduce the overall cost.
