The Digital Aerial Photo (UE Version) is the digital aerial photograph captured by the large format digital aerial camera which was put in commission in mid-2016. The digital aerial camera is able to capture five spectral bands information (Panchromatic, Red, Green, Blue and Near-infrared). The dynamic range of the colour information is higher than 12-bit. A total of three products, DAP_RGBI, DAP_RGB and DAP_CIR, are generated for each shot. Photo information, for example photo number, date of flight, flying height etc., is kept in the EXIF data instead of presenting on the image.

DAP_RGBI is digital aerial photograph in 16-bit file format consisting of four spectral bands (Red, Green, Blue and Near-infrared) with a file size about 2GB. No radiometric correction or colour balancing is applied in order to retain the original colour to facilitate spectrum study.

DAP_RGB and DAP_CIR are digital aerial photographs in 8-bit file format with radiometric correction applied with a file size about 760MB. DAP_RGB is RGB colour image (consisting of Red, Green and Blue bands) while DAP_CIR is false colour infrared image (consisting of Near-infrared, Red and Green bands).

The DAP-UE is suitable for photogrammetric measurement. In purchasing the DAP-UE, the relevant camera calibration report would be provided.

The DAP-UE is provided in TIFF Format with World File, the georeference information stored in World File is only for general position only.

PRDM250S Series is at 1:250 000 scale and PRDM500S Series is at 1:500 000 scale. Both series are Landsat 8 satellite image maps of the Pearl River Delta joined by 6 images. The map shows the name and location of administrative centres and settlements within the region.

To celebrate the 20th anniversary of the establishment of the Hong Kong Special Administrative Region, the SMO of the LandsD has published a new edition of aerial photo collection, Flashbacks of Two Decades in Hong Kong, to showcase major changes of the city over the last two decades through a display of the aerial photos taken by the LandsD at different times.
