Spatial resolution that recognizes 10cm as one pixel
| Its wide application in public sector policy formulation and implementation
| Also provides lidar, radar, and thermal infrared imaging

With the release of a national map implemented at 10cm resolution, the development of various spatial information utilization applications is expected to accelerate.

Sam-A Shipping announced on the 17th that it had succeeded in producing a high-precision aerial image map of the entire country with a resolution of 10 cm, maximizing the image map's discernibility.

A 10cm resolution refers to the spatial resolution at which a 10cm object is recognized as a single pixel. Aerial imagery maps are maps created by correcting for various distortions in the subject, making it appear as if viewed vertically from the sky.

The aerial image map produced this time has been accurately positioned and has been corrected for distortion and ups and downs of terrain features, and can be installed and utilized in various spatial information systems.

Sam-A Shipping conducted a total of 470 flights, covering over 120,000 km, to photograph the entire country, which covers over 100,000 km2, at a resolution of 10 cm. More than a year was invested in the follow-up correction work for the production of the aerial image map.

Sam-A Shipping expressed its hope that this high-precision aerial image map will be incorporated into various geographic information systems (GIS) and used for policy formulation and implementation in various public sectors.

Sam-A Shipping plans to release its aerial imagery map platform, Sky Map, to the public around August. The maps available to the public will be available at a 25cm resolution.

Sam-A Hangup CEO Gil Young-ok said, “We will continue the national land image data construction project through Korea Aerial Photography Co., Ltd., which we recently established with investment from Sam-A Hangup,” and “We will develop a specialized and comprehensive aerial photography business that utilizes not only optical images but also lidar, radar images, and thermal infrared images, utilizing manned and unmanned aircraft, helicopters, and satellite images.”

Meanwhile, LiDAR (Light Detection And Ranging) fires laser pulses from an aircraft and measures the distance to objects by receiving the reflected pulses from ground objects. It is similar to radar using lasers.
