摘要：Several scientific communities concentrate their efforts using photogrammetric techniques in the field of modelling urban areas. On the other side – with the access to high resolution satellites – also remote sensing in urban areas is present since a few years. At the same time, the shift from analytical to digital photogrammetry is now effective. Therefore, remote sensing and photogrammetry become closer as never before and this tendency is also remarkable in the corresponding software. Remote sensing is an invaluable tool in fields where spatial and spectral information is required. For topics like land use evaluation or change detection at regional scales, image processing techniques used for optical satellite imagery have proved their potential. Familiarised with the problem of modelling urban areas using photogrammetric techniques, our team extended its research topics by integrating knowledge resulting from satellite imagery processing. For this purpose, investigations with photogrammetric software and remote sensing software are realised during practical works with students of the department of surveying at ENSAIS Strasbourg. After creating a digital terrain model resulting from the restitution of stereoscopic photographs, several orthophotos are created and mosaicked together. The step of geocoding and mosaicking images has been attempted in parallel using on the one side exclusively photogrammetric tools and on the other side solely remote sensing tools. Results were assessed in a quantitative way, based on local and global precision and in a qualitative way, visualising the mosaicked area through a three dimensional representation
