ORTHO-PHOTOGRAPHY
Sometimes a good photograph can tell a story better than a line drawing, especially if that photograph can behave like a measured drawing… "Ortho-photos" (also known as scalable- or rectified photographs) are images that have been distorted in a controlled way so that the pictures match real world conditions such as size and shape. As such, they can be used as digital maps that accurately describe the existing conditions of a surface.
When placed into a CAD file, these images and linework together form a HYBRID DRAWING that uses both raster- and vector- data to capture and represent existing architectural conditions.
A powerful MOSAIC IMAGE is created when a number of “ortho-photos” are assembled together into an accurate line drawing in CAD format. This technique provides a way to create a photographic image that can “see around” columns, trees or other visual obstructions - allowing a surface to be viewed from multiple viewpoints simultaneously.
