The concept of layers in a Geographical Information System.

Expert Solution & Answer
Check Mark

Explanation of Solution

Layers are geographic data of different types which are gathered and encrusted together in a Geographical Information System (GIS). Layers can be recorded digitally and are inculcated in a GIS database.

Each layer could be spatially related information which shows zoning, floodplains, wetlands, soils, topography, hydrography, geodetic reference framework and so on. The layers combined bring all data in a common spatial reference system. A layer can have its own labeling properties, datasets, and map symbols.

Consider the building floor layouts illustrated below. These are referred to as Floor Layout A and Floor Layout B. Assume the floor to be built with composite steel-concrete construction (i.e. it is a composite steel-concrete floor). concrete core typical column Floor Layout A concrete core perimeter of the building floor perimeter of the building floor Floor Layout B (i) Provide two qualitative floor layouts for the primary and secondary beams for the Floor Layout A (Floor Layout A is shown above). Make sure to clearly draw the 2 floor layouts highlighting primary and secondary beams. Comment on the advantages and disadvantages of the two floor layouts with respect to one another. (ii) Consider Floor Layout B (Floor Layout B is shown above) and sketch one qualitative floor layout in which you provide qualitative locations of the columns, primary beams and secondary beams. Comment on the benefits of your selection of the positions of the beams and columns. Feel free to introduce any…
Consider the two composite columns shown below and denoted as columns 1 and 2. These columns have same gross area but differ in the geometries of the steel and concrete components. In particular, the square steel hollow section in section A-A (for column 1) has thickness of t, while the square steel hollow section in section B-B (for column 2) has thickness of 2t. a t t Column 1 steel steel concrete concrete B B Column 2 2t 2t 2t 2t a a Section A-A (for column 1) a Section B-B (for column 2) Assume that these columns are subjected to the same sustained load Po applied at time to and maintained constant afterwards (see time axis below). РА Ро 0 time Provide a qualitative description of the variation over time due to creep effects (do not consider shrinkage effects in this question) of the following variables for each of the two columns considered (i.e. columns 1 and 2): 1) deformations in the concrete 2) deformations in the steel 3) stresses in the concrete 4) stresses in the steel For…
For the truss shown in Fig 2, determine the nodal displacement and member forces for all elements of the truss. Assume for each member A = 0.0015 m2 and E = 200 GPa please show all working, relevant FBD's and use ID's indicated in the diagram.    Note: the truss has a vertical measurement of 2m and a horizontal mesurement of 2m
