Not illustrated. 1922 Excerpt: ...of brick courses or of siding boards may be counted and, by measuring these features where they are within reach, the inaccessible dimensions may be arrived at. Another method of obtaining such dimensions is by taking photographs of the elevations, preparing a scale from known dimensions on the picture and using this to measure those parts that are out of reach. Roof slopes, chimney heights, etc., may also be found if the pictures have been taken from the proper station points. The photographic record will be found of much value in the subsequent work. Contour Map or Site Plan.--When it is necessary to design a building for a site that is not level, the architect must know just how high each point is above the lowest part of the site. This information is obtained by the surveyor and presented in a manner similar to that shown on Plate 31, which without the building, is called a contour map. By way of an explanation of this map, imagine a flooded condition of the neighborhood in which the water is gradually rising. The part of the lot first covered by the water would be that at the corner of Salem Avenue and North Harvard Boulevard. Here the shore line would follow the dotted line figured 101. After the water had risen 4 feet more the shore line would follow the dotted line /05 and the water would have almost reached the location of the building. Thus it will be seen that each dotted line represents points of the same level across the lot. Notice on the curb near the street intersection the bench mark which is figured 100. This is always established on some fixed object and the various levels measured from it by means of an instrument called a surveyor's level. Notice now the note on the plan of the building which says that the basement floor elevation is 10...
