In the image to the right, the red marker is marking the tower which rises to the right of it, not the tower with the roof the marker is over top of. Sometimes satellite imagery of a city shows buildings from an oblique (angled) view and a building may appear offset from its actual map location. Tall buildings on the map are marked at the position where they rise from the ground. empire state building (19311971 / 20012012) designed by shreve, lamb & harmon and built in just one year, from 1930-1931, the empire state building has a roof height of 1,250 feet (380. Some buildings appear to be marked in the wrong location. The building may simply not exist in the SkyscraperPage database at all. The building may be outside of the city boundary. The maps may be expanded in the future to include additional types of structures. Also, structures such as Toronto's CN Tower or Seattle's Space Needle, while certainly being quite tall, aren't marked because they aren't considered as highrises. In the image to the right, the lower building, while casting a large shadow, is not marked as a highrise because it has only 10 floors, while the building across the street from it, which has 13 floors, is marked. For example, a 10 storey residential building (with a height of below 35 meters) is not considered a highrise and will not be marked on the map. Some multi-floored buildings which are visible on the satellite photos but aren't marked may not be considered as a highrise. Only highrise buildings are marked (a highrise is a multi-floored building of at least 35 meters in height or at least 12 floors). Out of a total of 109,519 highrises in our world-wide database which are eligible for inclusion on the highrise maps, only 102,410 of them have had their location data set and actually appear on the maps. Our editors may not yet have identified and marked every building in the city. This is a sub-category of Under-construction. On-Hold - Construction had begun at one point but has now stopped. Includes both structures which have been approved by local authorities and those which have not (we don't have a distinct 'approved' category). Proposed - Structure is planned to be built and construction hasn't yet begun. Excavation doesn't count as construction. Structural components are being assembled permanently on-site. Under-Construction - Structure is currently under-construction. Structures undergoing renovation remain in this category. Construction is complete and structure has potential for use.
