# UbiComp:GIS:AllenCenter

It is useful to know the latitude-longitude of key points for the Allen Center. Consider the following map of the third floor:

The coordinates for points with red labels were pulled from MetroKC GIS building outlines for the existing EE building. Unforunately, the Allen Center itself is too new at the time of writing (2005) to have building outline data in GIS. As such, the points with green labels are extrapolated using a Least Squares regression against all existing points on the given map image. Also, it's not exactly clear at what points in physical space the building outline coordinates are taken at. Thus, if you are looking for accuracy of less than a foot or two, these coordinates probably aren't going to do it.

That said, the measurments seem to be most accurate when placed at the exterior corner of the labeled point. For example, at a given point on the map, the coordinate seems to refer to exterior corner of the wall joint, as oppossed to the interior intersection of the two walls. This makes some amount of sense, since a surveyor is likely taking the measurments right at the corner of the building.

For those trying to build multi-floor models, each floor is 4 meters above the previous, with the exception of the first floor, which is 5 meters above the atrium. The landings for the atrium stairs are exactly halfway between the two floors they connect. Actual heights for each floor are given below.

### Height Data

These were deduced with a ruler, and so may not be perfect. They are close enough for most things, though, and assume that the atrium floor is at 0 meters. The landings for the staircases between the 2nd through 6th floor are all spaced exactly halfway between the two floors. The two landings on the main staircase connecting the first and second floors are at 1.23m and 3m.

- Atrium: 0
- Second floor: 5
- Third floor: 9
- Fourth floor: 13
- Fifth floor: 17
- Sixth floor: 21
