Development of high performance CPU, cameras and other sensors on mobile devices have been used for wide variety of applications. The applications require self-localization of the devices. Since the self-localization is based on GPS, gyro sensor, acceleration meter and magnetic field sensor (POS) of low accuracy, the applications are limited. On the other hand, self-localization method using images have been developed, and the accuracy of the method is increasing. This paper develops the self-localization method by integrating sensors, such as POS and a camera on a mobile device. The proposed method mainly consists of two parts : one is the accuracy improvement of POS data with filtering, and another is development of self-localization method by integrating POS data and images. The POS data filtering combines all data by using Kalman filter. The estimated exterior orientation factors are used as initial value of ones in image-based self-localization method, which is based on structure from motion. The exterior orientation factors are integrated and updated by applying bundle adjustment. Through experiments with real data, the accuracy improvement by the proposed method is confirmed.

In the last few years, SfM (Structure from Motion) based on photographs taken from UAV (Unmanned Aerial Vehicle) has attracted a tremendous amount of interest for the creation of DSM (Digital Surface Model) and other morphometric products. However, the accuracy of the derived DSM hasn't been sufficiently evaluated yet. Therefore, the present contribution aims to compare UAV-based SfM data against TLS (Terrestrial Laser Scanning) derived DSM data. The fieldwork was carried out on a wave-cut bench in Kanagawa Prefecture (Japan). Results have indicated that DSM data derived from UAV-SfM can create a point cloud of comparable density to the one created by TLS, with a maximum deviation of 10 cm from the TLS data. The UAV-SfM technique has a great potential for a wide range of application, because of its high data accuracy, low acquisition and operational costs, allowing high spatial and temporal data recording.

In the 8th year of the reign of Taisho (1919), with the arrival of the French tutorial unit, the Japanese Army started its aerial photographing.In the 12th year of Taisho (1923), the Shimoshizu military aviation school to which the French tutorial unit gave direct training, took aerial photographs of Tokyo immediately after the great Kanto earthquake. They played an important role in deciding the restoration plan. Triggered by this fact, 6 big cites including Nagoya, Kyoto and Osaka took the aerial photographs for the use of city planning, in the following 13th year of Taisho. The military aviation schools carried out the job in the guise of the military training.In the 8th year of Showa (1933), demands for the aerial photograph raised as application of the City Planning Act was extended to cover the new industrial cities. In the 12th year of Showa (1937) . the Japan-China war became intense and the cooperation from the military aviation schools went unattainable. The situation encouraged the birth of private companies undertaking the aerial photography. In the same year the Military Secret Protection Act was enacted and the aerial photographs were kept out of the public eyes as a part of military secrest. The city of Osaka has preserved the negatives taken in the years of 3rd and 6th of Showa in spite of the strict restriction and regulation of the Army.

We have developed a point-based rendering application with high-speed spatial interpolation using a point cloud to generate virtual reality (VR) data called LiDAR VR. This application can not only transform from a point cloud to VR data but can also regenerate missing point data in the rendered result from a selected viewpoint. Moreover, we have focused on the following features of the LiDAR VR generation. First, panorama imagery can be generated automatically from many viewpoints from one observation data set. Second, it is possible that a spatial interpolation with rendering results can reduce the processing task. These features have been verified using case studies.

We propose a method for obtaining validation data for the moderate-resolution-sensor-derived Fire Radiative Power (FRP) products from the high spatial resolution satellite data. This method uses two shortwave infrared channels (1.6 [μm] and 2.2 [μm]) to retrieve FRP validation data. Although fire-contaminated high spatial resolution pixels are mostly saturated because of intense fire radiation, our method exploits the saturated fire pixels for FRP validation data retrieval and as the result, an estimation width is obtained as FRP validation data. In this study, FRP validation data was constructed using the ASTER high resolution data and was evaluated by comparing the simultaneous observed MODIS FRP products. The correlation coefficients between our method derived FRP validation data and the MODIS FRP were approximately between 0.7 and 0.9. The corresponding rates between our method derived FRP validation data and the MODIS FRP were approximately between 0.7 and 0.8.

We examined the newly published high spatial resolution digital elevation data, ALOS 3D World Topographic Data (AW3D), for application of the analysis of locational condition of agriculture mainly compared with ASTER Global Digital Elevation Model (GDEM). The study site was selected in the middle part of Burkina Faso, where topographic condition was consisted of gentle slopes even around watershed boundaries and bottom of valleys. Examination was focused on sloping features and river/watershed systems as comparing elevation profile along transect line measured by handy GPS. As a result, GDEM contained random deviations with amplitude of several meters, which might induce apparent high degree of slopes. On the other hand, AW3D was proved to fit optimally with profile of GPS measured data and did not show large deviation as appeared in GDEM profile. River course and watershed boundary obtained from AW3D and GDEM were not identical and GDEM might produce unrealistic river course in close up scale map. However in regional scale, both AW3D and GDEM produced river course and watershed boundary with similar morphological pattern.
