In recent years, a wide variety of action cameras have become available on the market as mobile cameras, and smartphones, which have become a necessity in modern life, can be used in the same way. It is not uncommon for these devices to be equipped with GPS and 6-axis sensors, and to be able to acquire the latitude and longitude of the shooting location and the azimuth angle of the shooting direction along with the image. When aiming to utilize these mobile cameras for acquiring image data along a set route over a wide area and for observation and measurement based on these images, it is necessary to take into account the characteristics that the images are time-series data, taken at various locations with various elevation angles and magnifications. In order to utilize images for observation and measurement, it is essential for data viewers to be able to easily grasp "when and where" the various images were taken. However, it is difficult for the average data viewer to determine the location of an image taken by a mobile camera from the latitude, longitude, and azimuth angles associated with the image and the captured object.

Therefore, we have studied a visualization method to display images taken by mobile cameras in conjunction with or integrated with a 3D GIS (Geographic Information System), so that anyone can easily grasp the locations captured in the images.
