3.Explain the AutoCAD CONNECT command. What is connected to what?4.Describe two AutoCAD methods to view the information associated with a connected shapefile layer.5.Several ASCII point file formats, including text (.txt) and comma separated (.csv) formats, may be MAPIMPORTed into AutoCAD. In either case, the attached file format must conform to the AutoCAD selected file format. Referring to the screen shot for an ASCII comma delimited (.csv) file MAPIMPORT, what does PNEZD stand for? 8
6.The FAA maintains a national, Digital Obstacle File (DOF) (updated every 56 days) describing all known obstacles or objects of interest to aviation users in the United States. Any obstacle higher than ___________ AGL is assumed to be a hazard to air navigation (obstruction) unless further aeronautical study concludes that the object is not a hazard. In addition, other obstacle less than ___________ AGL in height may be an obstruction depending on their distance from an airport. Fill in the following table. Obstacle Distance from Airport nm Maximum Allowable Height Above Ground Level (AGL) or Airport Elevation Whichever Is Higher In Order NOT To Be Considered An Obstruction To Air Navigation 3 or less 3-4 4-5 ce56c12fe6417f77c7534ea9b4c8bef0659662c8 16:30:24 9

Include at least (a) the basic building blocks for each format, (b) which format scales up and down more readily and maintains clarity when zoomed in, (c) which format captures hues and tones better, (d) which format is most common in graphics programs such as Photo Shop, (e) which format is most common in GIS maps.3.Name the most popular GIS geospatial digital vector storage format. State its file name suffix and three accompanying file name suffixes. 4.List at least four NEPA environmental impact categories that require analysis for any proposed airport expansion which lend themselves to GIS map analysis.5.When creating a multilayer GIS map, discuss a major consideration to insure layer spatial compatibility.
