Geographical Information System (Design Geodatabase) An Environmental Protection Agency is planning to simulate flood caused by a dam breach. When the dam breach occurs, the water will spill to the river below, and flood will spread to the area along the riverbanks. This flood can be simulated based on the land elevation and land cover types. The agency would like to estimate the number of houses that will get an impact from the flood, and the road network for evacuation plan. You are required to design a geodatabase that will provide necessary information for the agency. Question: a. Determine attributes for each dataset. b. Apply some topological rules for your datasets.
