Palestine 1923 / Palestine Grid (EPSG:28191) is a historic projected coordinate system established by the British Military Survey in 1923 to serve as the foundational mapping framework for the region . Developed under the Palestine 1923 datum, this system was meticulously designed to support cadastral surveying, engineering projects, and topographic mapping throughout the British Mandate period . While modern systems like Israeli TM Grid (EPSG:2039) have largely superseded it for contemporary applications, the Palestine Grid remains essential for interpreting the vast archive of 20th-century geographic data across Israel, Jordan, and the Palestinian Territory .

Egypt Red Belt coordinate system is a national projected coordinate system established in Egypt during the 20th century, forming part of the Old Egyptian National Coordinate System of 1907, together with the Egypt Blue Belt and Egypt Purple Belt. Based on the Helmert 1906 ellipsoid and employing the Transverse Mercator projection, this system was primarily used for engineering surveys and topographic mapping in the Nile Delta and along the Red Sea coast. Although modern GNSS applications are increasingly prevalent, the Red Belt system remains irreplaceable for processing historical Egyptian land records, Suez Canal infrastructure archives, and 20th‑century national topographic map series.

Libya Transverse Mercator coordinate system (EPSG:2062) is a projected coordinate reference system officially adopted by the State of Libya for national topographic mapping and cadastral surveying. Originally developed in the mid-20th century under Italian and later international geodetic influence, the system is based on the War Office ellipsoid and is historically tied to Libya’s national mapping infrastructure. While newer geocentric systems are increasingly used for GNSS applications, Libya TM remains critical for processing and maintaining historical geographic records, land administration documents, and foundational topographic series across the country.

Saudi Aramco Lambert coordinate system (EPSG:2329) is a regional projected coordinate system historically developed and utilized by the Saudi Arabian Oil Company (Saudi Aramco) for its internal exploration, mapping, and engineering operations. This proprietary system, based on a modified regional datum, was established to meet the company's specific needs for geodetic control and mapping across its expansive operating areas in eastern Saudi Arabia. While modern global systems are now prevalent, understanding this legacy system remains crucial for interpreting and integrating a vast archive of historical well data, seismic surveys, pipelines, and facility maps that form the foundation of Saudi Arabia's petroleum industry.

Qatar National Grid (Qatar National Grid 2009 | EPSG:28600) is a projected coordinate system officially adopted by the State of Qatar for national surveying, mapping, and land administration. Established in 2009 through collaboration between Qatar’s Ministry of Municipality and Environment and international geodetic experts, this system provides a modern, GNSS-compatible framework optimized for Qatar’s compact territory and rapid urban development. It supports high-precision applications in construction, infrastructure, and cadastral management, serving as Qatar’s primary legal and technical coordinate reference.

Jordan TM (Jordan Transverse Mercator | EPSG:3144) is a projected coordinate system officially adopted by the Hashemite Kingdom of Jordan for national mapping and surveying purposes. Developed under British technical influence during the mid-20th century, this system serves as Jordan's primary framework for topographic mapping, land administration, and infrastructure development. While modern GNSS-compatible systems are increasingly utilized, Jordan TM remains essential for interpreting historical geographic data and maintaining continuity in the country's geospatial records.

Israel TM Grid (Israeli National Grid | EPSG:2039) is the official national projected coordinate system adopted by Israel, primarily used for surveying, mapping, and engineering construction within the country. This coordinate system is based on the Israeli national surveying system and employs a Transverse Mercator projection to facilitate precise measurements and map compilation in Israel and its surrounding regions. Although global positioning systems (such as WGS84) have gained widespread use, the Israel TM Grid remains highly valuable for local engineering, land management, and historical geospatial data applications.

Hong Kong 1980 Grid (Hong Kong 1980 Coordinate System | EPSG:2326) is a regional projected coordinate system specially designed for Hong Kong's urban surveying and mapping needs during the late 20th century. Developed as part of Hong Kong's territorial surveying framework, this system employs a transverse Mercator projection centered on the region's specific geographical characteristics. Although now supplemented and partially superseded by modern geocentric systems, it remains crucial for processing legacy engineering plans, cadastral records, and historical urban data from Hong Kong's development boom period.

Xian 1980 (Xi'an 1980 Coordinate System | EPSG:4610) is a Chinese national geodetic datum established in the 1980s as an improved successor to the Beijing 1954 system. It was developed to address the limitations of the earlier non-geocentric datum and to better support China's growing surveying, mapping, and infrastructure needs. Based on the IAG 1975 ellipsoid with a geocentric origin, Xian 1980 represented a significant step toward modern geodetic standards in China. Although now superseded by the fully geocentric CGCS2000, it remains important for processing data from the late 20th century and serves as a transitional benchmark in China's geodetic evolution.

Beijing 1954 (Beijing 1954 Coordinate System, EPSG:4214) is a national geodetic datum established in China during the 1950s. As the first nationwide unified coordinate system introduced after the founding of the People’s Republic of China, it is a non-geocentric (local) datum designed for nationwide surveying and mapping. It was developed with reference to the Soviet geodetic framework and is based on the Krasovsky 1940 ellipsoid. This coordinate system was used extensively across China for foundational surveying, topographic mapping, infrastructure construction, and land administration over a long period, forming the basis of China's surveying and mapping system in the latter half of the 20th century. Although it has now been officially replaced by the more precise and geocentric CGCS2000, it still plays a significant role in processing historical and legacy data.
