Introduction into Surveying
9.CAD
Elements of CAD-data input, data editor, data out forward/info out
Data input
-manual entry- downloaded from data recorder
-format and standards Python coding tables
Import other information-aerial or satellite images
Input to manual entry to method
Data edit (edit, calculating design)
-adding, removing and manipulating info Neo Geo functionality
-analysis capability-adjustment capability-pre-designed elements forward/functions-2D, 3D, 4D
Data out forward/info out
Hard copy-2D plotter/printer (3D printer?)-soft copy-digital files (2D/3D), fly throughs, video-
formats-plan forms-scaling
Pros
- -ease of changing drawing elements
- -management of data
- -Format options
- -consistency and traceability
Cons
- -cost- need to update to maintain currency-
Raster and Vector data
-Raster tends to provide the interpretive, big picture info/
-vector provides the five resolution, measurement/dimensional level detail

Document Summary
Elements of cad-data input, data editor, data out forward/info out. Adding, removing and manipulating info neo geo functionality. )-soft copy-digital files (2d/3d), fly throughs, video- formats-plan forms-scaling. Raster tends to provide the interpretive, big picture info/ Vector provides the five resolution, measurement/dimensional level detail. Disadvantages -discrete cells data is given at fixed intervals finite limit to our ability to specify a value for a specific point location item is either in one cell or another cannot be in two. Simple vector structures store x,y coordinated for points 3d x,y,z. A series of lines may represent an enclosed area (polygon) All features (point, line, area) can be handles in vector format. Have certain properties that make them more useful for representing certain features. Historically, vectors were first employed because of the digitalization of complex map features. The representation of non-regular areas by rater grids- will intrinsically require approximation.
