Geospatial (BIM/CADD/GIS/Survey) Functions: Coordinate the management and implementation of GIS standards throughout our technical products. This effort extends across multiple organizations at the District Offices. Work with HQ and our Districts on CADD / BIM standards and implementation, with the end objective being to assist our customers to more effectively operate and maintain their facilities. Our Districts are becoming competent in dual platforms: Bentley Microstation and Autodesk AutoCAD. SWD is utilizing GIS for its analytical and data integration capabilities, and for output including and Flood Mapping display.

Building Information Modeling
Building Information Modeling (BIM) is the latest technology to offer significant improvement in the speed, cost, and quality of facility planning, design and construction, and operations and maintenance. One eloquent description of BIM is an Intelligent Simulation of Design Intent. In more practical terms, the potential of BIM stems from its value as an interchange mechanism between the tools used to perform the various functions of the AEC industry (standards) and the ability of computational tools to manipulate the model directly, with or without human intervention (computable). In a typical BIM-enabled process, the data model serves as the principal means for communication between activities and professionals.
Computer Aided Design and Drafting, also CAD
Computer-aided design (CAD), also known as computer-aided design and drafting (CADD is the use of computer systems to assist in the creation, modification, analysis, or optimization of a design. Computer-aided drafting describes the process of creating a technical drawing with the use of computer software CAD software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database for manufacturing.CAD output is often in the form of electronic files for print or machining operations. CAD software uses either vector based graphics to depict the objects of traditional drafting, or may also produce raster graphics showing the overall appearance of designed objects.

GIS Geographic Information System (GIS)
GIS is a system of hardware and software used for storage, retrieval, mapping, and analysis of geographic data. Practitioners also regard the total GIS as including the operating personnel and the data that go into the system. Spatial features are stored in a coordinate system (latitude/longitude, state plane, UTM, etc.), which references a particular place on the earth. Descriptive attributes in tabular form are associated with spatial features. Spatial data and associated attributes in the same coordinate system can then be layered together for mapping and analysis. GIS can be used for scientific investigations, resource management, and development planning.
GIS differs from CAD and other graphical computer applications in that all spatial data is geographically referenced to a map projection in an earth coordinate system. For the most part, spatial data can be "re-projected" from one coordinate system into another, thus data from various sources can be brought together into a common database and integrated using GIS software. Boundaries of spatial features should "register" or align properly when re-projected into the same coordinate system. Another property of a GIS database is that it has "topology," which defines the spatial relationships between features. The fundamental components of spatial data in a GIS are points, lines (arcs), and polygons. When topological relationships exist, you can perform analyses, such as modeling the flow through connecting lines in a network, combining adjacent polygons that have similar characteristics, and overlaying geographic features.
