Qatar Completes Aerial Photography Survey to Update Digital Maps
The aerial survey system for upgrading digital maps of Qatar has become operational. Under the aerial surveys project for Qatar, the mission of aerial photography covering all parts of the country and Halul Island to take 20cm-accurate evaluative aerial photographs has been completed as the basis for updating the digital linear maps of the country.
摄影工作发生于2022年3月30日至2022年4月20日。该项目由市政部的地理调查系统（GIS）中心实施。
计划在2022年7月，为所有国家机构提供航空照片和更新的数字地图，可用于FIFA世界杯2022年活动的活动和项目中。它们稍后可以在该州的所有其他项目中使用，例如计划，教育，卫生，室内服务部，支持该国的决策和基础设施发展等。
与其他地理空间数据源集成
The aerial surveys and remote sensing using manned aircraft by GIS Center are aimed at achieving integration with other data sources that the centre is currently using, such as satellite images, mobile field surveys and drones.
The project is being implemented throughKhatib and Alami在招标之后，该部的大型招标委员会授予了该项目的设备和设备，包括载人飞机，现代无人机，摄像头，遥感和专用计算机。
This work is considered the beginning of the operation of the aerial surveys system for Qatar, which was recently received by the Ministry of Municipality, represented by theGIS中心作为负责更新卡塔尔数字地图并管理该国航空调查系统的所有工作的国家实体。
系统由一个dual-engine manned-aircraft specialized in aerial photography and remote sensing, along with all the equipment that will be installed on the aircraft for aerial survey, such as cameras, remote sensors and computers for aerial surveys, in addition to providing qualified operators for said devices and the rest of the technical cadres specialized in this field.
斜射图像和3D模型
The centre’s role is to provide basic geographical maps and digital topographic databases, establish and maintain geodetic networks and related services, and as part of the plan to develop national standards and specifications related to geographic information systems at the state level through the centre’s cadres without the assistance of companies from outside.
使用载人飞机进行空中调查和遥感，与当前使用的其他数据源集成，例如卫星图像，移动现场调查和无人机。
这一重要开发的产品包括处理和拍摄准确的空中图像，倾斜的航空图像，线性数据，3D模型数据，数字高程模型（DEM），遥感，LIDAR数据，用于测深的测深度测量数据，海洋测量和高光谱成像。
