Xlview

xlview is a spanish company deploying high definition street and river imaging technology with services called fotocalle and riverscan. the captured panoramic images of cities and rivers are associated with geographic coordinates. the images can then be used to connect information to specific places this information can then be used for tourism, urban applications and hydrological simulations. in addition to that, the panoramic photos can also be useful to monitor the evolution of cities and rivers over time. the first city mapping test was successfully completed in buenos aires in 2009. in 2010, xlview captured 16,000 images during the fotocalle tests in spain. the system can be set to trigger all four cameras at regular distances. the system can generate an output including measurements of position and orientation when the camera is triggered which is essential for accurately geo-referencing objects from the images.
