Harvey Post #6

This week Janelle taught me how to import CAD files into Arc and how to use these drawings to update the maps. These CAD drawings are great to work with, they are fairly straight forward and very accurate. I began this project by comparing the CAD drawings to the drawings we made from the geo-referencing last week. The drawings from the geo-reference were close but not exactly in the correct locations as indicated by the CAD drawings. In order to correct this I simply had to move my previously drawn figures into the corresponding locations based off the CAD drawings, which was pretty straightforward. Once this was finished, I used the CAD drawing to input the rest of the utilities onto our Arc map. Monday I put in all of the water infrastructure, including water mains, laterals, junctions, laterals, fire hydrants, and water meters. There was a lot of water structures within this new sub division and inputting them took the entire afternoon. Friday, since I was finished with the water infrastructure, I got to move on to the the easier storm and sewer utilities. Like, the water I began by correcting the previously drawn in structures from the geo-reference map and put them into their correct positions based on the CAD map. I then moved into inputting the new structures. For storm I input mains, inlets, outlets, manholes, and inlets with manholes. As for sewer I only needed to put in the manholes and the gravity lines, insuring they were headed in the correct direction. Janelle also taught me how to input different layers as well as create a query. The query was very interesting and I can see how useful / helpful it can be. Creating one is relatively straight forward but I would like to do some more in order to ensure I know how to use them. Another thing I would like more practice with is inputting layers into Arc. But overall, another great week with a lot of new information learned!
