GIS 1 Lab 1

GIS 335. Lab 1


Objective:
   The objective of this lab is to learn how to use multiple data frames in one map document. We will then construct maps of the world and the states in different projections. We also need to learn how to pick the correct projections for shapefiles that have different or undefined coordinate systems. Then we will need to display the maps in a visibly appealing way for the viewer.


Methods
   Part 1.
First, I imported the zip file for lab 1 date from my professors folder to my personal folder.
   Section 1:
I imported the country and geogrid shapefiles to my world data frame. The shapefiles came from the lab 1 data folder that I unzipped to my personal folder. I then changed the coordinate system, under the coordinate system tab in data frame properties dialogue, to (Geographic coordinate systems- world- wgs 1984).
   Section 2:
I inserted a new data frame and added the country and geogrid shapefiles again. I named this data frame Mercator Projection and changed the projection the same way as described in section 1 and selected (Projected coordinate systems- world- Mercator world). I created three more data frames and projections using the same method as above. For the first one I selected (projected coordinate system-world- sinusoidal). The second one I selected the (projected coordinate system-world- equidistant-conic). The third I selected (projected coordinate system-world- Robinson)
 Part 2.
   Section 1:
I created a new data frame for Wisconsin UTM. I then imported the states shapefile and selected Wisconsin from the attribute table. I then made a new layer from selection and exported the layer using current data frame coordinate system. I then change the Wisconsin UTM data frame to (UTM- NAD 1983, Zone 16N).
  Section 2:
I then inserted a new data frame and named it STATES. I imported the states shapefile and the stroads_mir5a. They do not match up so I went the project tool and selected the stroads_mir5a as the input and imported the states coordinate system so they would match. I then let the tool run. I then changed the data frame projection to (projected coordinate systems- continental- north America- north American lambert conformal conic)
 Part 3.
I switched to the layout view and organized all of my maps to fit one page. I added titles, scales, and north arrows to the maps that needed them using the insert tool. I then exported the map as a jpeg.
 Part 4.
   Section 1:
I imported the central_WI_Cts shapefile from the lab 1 data in my personal folder to a new blank map. The coordinate system is undefined so I changed the coordinate system to GCS north America 1983 using the projection define tool. After doing this I changed the projected coordinate system to 1983 state plane Wisconsin central fips 4802 using the project tool. I then add the Lower_chip_strms shapefile from the lab 1 data folder. This shapefile did not have the right projected coordinate system so I changed it to the 1983 state plane Wisconsin central fips 4802 coordinate system using the project tool. I then orientated the maps so that the fit one page adding a legend, scale, north arrow and title.
