The Urban Modelling Group (UMG) is based in the UCD School of Civil, Structural and Environmental Engineering at University College Dublin. Professor Debra F Laefer heads this group and it formed in 2006 to bridge the efforts of the architectural heritage community and those of practising engineers by introducing, adapting, and generating new technologies to help safeguard built urban heritage.

Photographic data regarding 444 builings in Dublin, Ireland, comprising primarily multi-layer images in Adobe PhotoShop (PSD) format. The majority of images consist of one or more photographic images that have been manpulated to create a single ortorectified image of a structure; a structure may be represented by more than one PSD file, such that 516 images in total are included in the dataset.

Consists of 4 orthorectified images of the structure. The orthorectified images have been derived from one or more photographic image that are included as layers in the original Adobe PhotoShop (PSD) file. The composite and other image layers have been extracted and saved in TIFF image files, as well as JPEG files in various resolutions to facilitate inspection.

Consists of 14 orthorectified images of the structure. The orthorectified images have been derived from one or more photographic image that are included as layers in the original Adobe PhotoShop (PSD) file. The composite and other image layers have been extracted and saved in TIFF image files, as well as JPEG files in various resolutions to facilitate inspection.

Consists of 8 orthorectified images of the structure. The orthorectified images have been derived from one or more photographic image that are included as layers in the original Adobe PhotoShop (PSD) file. The composite and other image layers have been extracted and saved in TIFF image files, as well as JPEG files in various resolutions to facilitate inspection.
