The Mohammed Bin Rashid Space Center today announced the completion of the development of an updated map for the emirates of Abu Dhabi and Dubai using modern high-resolution satellite images (mosaic images) via the Emirati satellite, Khalifa Sat, where the images were combined into one map known as (mosaic). It is a matrix of digital images that are collected through individual images of a sprawling geographic patch in order to obtain a comprehensive picture of a specific geographical area in high resolution. This updated map relies on conducting a comprehensive survey of the geographical regions in the Emirates, using remote sensing systems, image processing, and geographical information systems, which is an important reference for government and private agencies to update their smart services that are based on providing maps and geographic data constantly updated. The tasks of the new mosaic service for the Khalifa Sat satellite will include taking satellite mosaic pictures for the rest of the Emirates.

This came in the framework of the efforts of the Mohammed bin Rashid Space Center to support federal and local government agencies, research and academic institutions, as well as the private sector to take advantage of this type of technology that plays an important role in the interpretation process for large areas, which enables all beneficiaries to obtain accurate results.

This service will be provided to all government agencies free of charge in order to benefit the concerned authorities and enhance its role in the Emirati society, and expand the scope of utilizing space technologies owned by the Mohammed Bin Rashid Space Center. This type of satellite image is of great importance to the authorities involved in the sectors of infrastructure, urban planning, environment and climate change, energy, education, technology, roads and transportation and other vital sectors in the Emirates. Accordingly, the Mohammed Bin Rashid Space Center will receive requests to provide clear visual images of the mosaic system, after conducting a comprehensive survey of a specific area to meet the needs of the entity wishing to obtain a specific explanation according to the nature of the activity of each party.

For his part, Youssef Hamad Al-Shaibani, General Manager of the Mohammed Bin Rashid Space Center “The Mohammed bin Rashid Space Center seeks to contribute effectively to society through projects that support the development sectors in the Emirates. Over the past few years, the Center has established an important balance of efficiency and trust As an important space center, it has its weight in the impact that its projects and technologies are showing in its impact on other non-satellite sectors as well. The launch of the first mosaic of the satellite, Khalifa SAT, represents a strategic importance for us to support the infrastructure of all vital sectors in the country and enhance the strategic decisions of the main bodies operating in the Emirates.

Technical specifications

The Mohammed bin Rashid Space Center collects images of specific geographical areas taken through the “Khalifa Sat” satellite at specified time periods ranging from days to months. Then the process of processing and improving the quality of pictures and developing a single map of the geographical area to be covered with a high visual accuracy of 0.7 meters. Then the image processing team in the remote sensing section extracts the mosaic image of the region after completing the process of image processing and merging it, to provide the high-resolution image in “TIF” format, which is a known format for storing raster graphics.

methodology
In the context of explaining the methodology of the new satellite system, Eng. Ammar Saif Al Muhairi, Head of the Image Processing Department, at the Mohammed Bin Rashid Space Center, said, “The Mosaic imaging system of Khalifa Sat in the Mohammed Bin Rashid Space Center is going through a number of systematic stages in extracting images, It depends on 4 main steps. You start by collecting the individual pictures taken by the satellite spread over a certain geographical area in a specific time period. The center then performs the georeferencing of these images, which is a coordinate reference system used to ensure the highest possible resolution of the image. Next comes the image correction phase by enhancing contrast and different corrections to ensure that they are free of any distortions, so that all images become regular. Finally, the process of matching the colors of the image and mixing it comes, followed by subjecting the image to the test by the concerned team, and ensuring that it is completely correct before it is finally approved. “

This, and the efforts of the Mohammed Bin Rashid Space Center continue to spread knowledge and expand the scope of benefiting from its outputs, as the center seeks to extend cooperation frameworks to all sides, and is keen to hold periodic meetings with government departments to determine the nature of their activities and provide integrated solutions that meet their needs, and provide them with satellite images Required. The center’s services also extend to non-governmental entities in the private sector, as this represents the generalization of interest to the Emirates as a whole. This, in addition to cooperating with the national statistical centers in the Emirates because of the importance of the outputs of the satellite “Khalifa Sat” in the exchange of technical and graphic experiences, in addition to providing the various sectors with the basic data necessary to prepare reports on infrastructure projects under construction, as well as contributing to answering Urgent questions, which would support strategic decisions of all agencies in the government and private sectors.

It is worth noting that the Mohammed Bin Rashid Space Center owns 3 remote sensing satellites, «Dubai Sat 1 and 2» and the successor of Sat, as it was used in carrying out several scientific reports and studies, which are dedicated to the purposes of monitoring and monitoring the Earth, and providing satellite images.
