Abstract
Aerial photography is the activity of collecting data from objects on the earth's surface. Aerial photography uses aerial camera sensors mounted on an aerial vehicle. Aerial shooting activities can produce high-resolution image data with image sharpness and a good level of accuracy. This study uses two types of aerial photo data from different camera sensors. The first aerial photo data was obtained using an RCD30 digital aerial camera with a CCD image sensor. The second aerial photo data was obtained from the DMC III digital aerial camera with a CMOS image sensor. The purpose of this study is to examine the sharpness and ease of object identification from two aerial photos produced by CCD and CMOS sensors. Groups of objects that measured and compared are roads, buildings, vegetation, bodies of water, and open land. The measurement method uses a questionnaire that applies a Likert scale. The questionnaires were distributed online to specific respondents who have experience in aerial photo interpretation and a profession in the field of mapping. Assessment of the quality of the recording is carried out in 9 zones of the recording area. This zone is intended to assess the consistency of the quality of the recording results. Statistical analysis used is descriptive statistics and non-parametric statistics to see patterns, trends and correlations between assessment components. Based on the results of the analysis, it is found that aerial photos recorded using the CMOS sensor provide 5.29% better observations than aerial photos recorded by the CCD sensor. In general, the use of a CMOS sensor for aerial shooting can be stated to be more reliable in recognizing objects than the use of a CCD sensor.
