ICEYE’s SAR Dataset Overview: City Infrastructure of Muscat, Oman

Spot SAR imagery reveals many details in dense urban areas and provides invaluable insights for city planning, observations and monitoring of urban activities.

This blog post summarizes information about the Spot dataset of Oman, which is now available as a free-of-charge download from our website. The dataset includes a SAR image of the downtown area of Muscat in Oman and an image of the Muscat International Airport. Both high-resolution images show many features of the city structure and activities.

With this dataset, you can evaluate the quality of ICEYE’s Spot SAR data and test its suitability for your urban data use cases.


Spot Imagery For Urban Monitoring

In Spot imaging mode,  a very fine image resolution of 0.5 m x 0.25 m (slant range x azimuth) is achieved.

The information content of these very high-resolution images enables detection and identification of small objects and feature extraction in urban areas. Analysts can use repeated data acquisitions to detect newly constructed and destroyed buildings, measure building sizes and urban densities, and obtain information on urban sprawl and vertical growth, to name a few. The images can also serve as input for updating cadastral maps.

Precise monitoring and change analysis of activities on ground can be performed with ICEYE satellites. With an approach of imaging the location multiple times analysts can track urban development over time.

The images of this SAR dataset are available in both data formats, SLC (single look complex) and GRD (ground range detected). For more information on these data formats, read the SAR Product Guide.


Dataset In A Nutshell: What Can You See In These SAR Images From Muscat, Oman?

Both images in the dataset are standard Spot products, each covering an area of 5 km x 5 km (width x length). All the technical information about the data, such as the satellite look angle, the time of acquisition, and the orbit direction is included in the XML files. These files are provided in the corresponding ZIP folders available for download.

Image #1 - Muscat International Airport, Oman

Muscat International Airport is the main international airport in Oman and is located 32 km from the old city of Muscat. The image shows the area surrounding the airport, the feeder roads, and the coast facing the Gulf of Oman (Figure 1).

The Spot imagery provides high-resolution details of the entire airport site: in addition to the two parallel runways and taxiways, parked aircraft and an airplane on a taxiway can be detected. Many individual features of the terminal and airport buildings are visible, as well as the evenly spaced lamp posts of the parking lot.

A golf course is located directly on the coast. West of it, four breakwaters are built into the sea.

Image #2 - City of Muscat, Oman

The image shows Muscat, the capital city of Oman (Figure 2). It is located in a key geographical location at the crossroads of the sea routes that connect Asia with Africa and Europe.

This Spot image shows some great features on a building level. For instance, the Sultan Qaboos Grand Mosque (Figure 3) and the Sultan Qaboos Sports Complex (Figure 4) are clearly visible in full detail. Analysts can detect the road network and map the local buildings and vegetation.
