Exploded AxonometricAdd an Illinois Landuse Raster Image

1. Go to the Illinois Geospatial Clearinghouse (https://clearinghouse.isgs.illinois.edu/front-page). You’ll find this most easily using google.

2. In the search box type ‘Illinois Gap Analysis’

3. The first result should be ‘Illinois Gap Analysis Program: Land Cover Classification, 1999-2000’ Click on that result.

4. Read the summary and then click on the ‘Data’ tab.

5. Scroll to the bottom of the page and download ‘GAP GeoTiff.zip’ Unzip and save the file to a location you can access from ArcMap.

6. Open ArcMap and set the projection to Illinois State Plane west.

7. Navigate to the GAP GeoTiff folder and add the ‘ilgapveg_b.tif’ file.

8. Add the tl_2016_us_county shapefile from Tutorial #1.

Clip Raster

1. Make sure the us_county shapefile is on and on top of the tif file.

2. Click on the selection button in the toolbar.

3. Click on Peoria County.

4. Right click on the us_county layer, go to selection, create layer from selection.

5. Rename the new layer ‘Peoria County’

6. Go to Geoprocessing in the Menu bar and select ‘Arc Toolbox’

7. Go to Data Management > Raster > Raster Processing > Clip (you can also simply search for ‘clip raster’ in the search bar.

8. Set ilgapveg_b.tif to your input raster.

9. Set your Peoria County layer as the output extent.

10. Go to Environment and set Output Coordinates to ‘Same as Display’

11. Set the ‘Output Raster Dataset’ location to your working folder.

12. Click OK.

13. You should now have a much smaller version of the GeoTiff Raster.

Raster to Polygon

1. Go to ArcToolbox > Conversion Tools > From Raster > Raster to Polygon

2. Select your clipped raster as the input. (make sure you select the clipped one, converting the whole Illinois raster to polygons will be processing intensive)

3. Make sure Field is set to ‘Value’

4. Set the output location to your working folder.

5. Click OK.

6. A series of polygons will appear on top of the raster image.

7. Go to ‘Symbology’, turn on Categories, and set the categories to the Value field.

8. You should see that the coloration of the new polygons matches the pattern of the colors on the original raster, but not the specific color.

Join Name Data

1. Navigate to the GAP GeoTiff folder that you unzipped earlier.

2. Open the ‘readme_geotiff.txt’ file.

3. Starting with the line that begins with ‘11’ select all the lines down to the line that starts with ‘54’.

4. Copy the selection.

5. Open Microsoft Excel.

6. In a blank workbook click the upper left cell and paste the data from the .txt file.

7. Numbers should appear in one cell, and text descriptions in the next. Go to file, Save As and save the file as a .csv file into your working folder. Ignore the warning from Excel.

8. Go to ArcMap, right click on layers, and add data. Navigate to your .csv file and add it to your map. You’ll only see the .csv file appear in your Table of Contents. Nothing will appear in the map window.

9. Right click on the polygon layer you created from the raster image.

10. Go to Join and Relates, click on Join.

11. Set #1 to ‘gridcode’

12. Set #2 to your .csv file.

13. Set #3 to ‘Field 1’

14. Click OK.

15. Right click on your polygon layer and go to attributes table. Each polygon should now have a label of what type of land use the polygon represents.

16. Go to Select by Attributes and input: “Land-Use_Key.csv.Field2” LIKE ‘%FORESTED LAND%’ to select all forested land.

17. Right click on the polygon layer go to selection and created new layer from selected features.

18. Do the same for: “Land-Use_Key.csv.Field2” LIKE ‘%WETLAND%’ to select all wetlands.

19. Right click on the polygon layer go to selection and created new layer from selected features.

20. Go back to Select by Attributes and this time select Surface Water and create a new layer.

Setup a Layout View

1. Go to view > layout.

2. Go to File, Print Setup and set your page size to 12” x 12”

3. Center Peoria county on the page at a scale of 1:200,000

4. Make sure your Peoria Count layer is on top, and is set to outline only.

5. With only the county line and one of your land use layers on (either forest, wetland, or surface water) Go to File > Export and export at JPG file at 150 dpi.

Create Axonometric

1. Open Illustrator

2. Create an 11”x17” file.

3. Go to File > Place and place each of the three exported images.

4. Go to Object > Transform > Scale and scale each image by 50%

5. Create two new layers and place each image on its own layer.

6. Line the images up using the align tools.

7. Select all three images and go to Effect > 3D > Rotate. Select ‘Isometric Top’ and click OK.

8. Go to Window > Transparency and set each image to ‘Multiply’

9. Using the layer lock feature, lock all but one layer at a time and arrange them into an exploded axon.

10. Go to File > Save As and Save your file as Lastname_Axon.pdf

BasemapsAdd a Basemap

1. Make sure you to save your file. Basemaps can cause ArcMap to crash.

2. Make sure you are in the layout view, looking at the same view as the last section.

3. Go to the ‘Add Data’ button on the top of the toolbar and click on the black arrow next to the button for the pull-down menu.

4. Click on Add Basemap

5. Choose one ot the available basemaps and click OK.

6. You may have to wait for a bit for the basemap to show up.

7. Export your basemap and the peoria county outline as a JPG

8. Following the same procedures as before add these layers to your Illustrator File.

9. Add text that labels each layer.

10. Export your Map from Illustrator as Lastname_Axon-Base.pdf

From Google Earth to ArcMapFind Place in Google Earth

1. Open Google Earth

2. Search Chicago Parks

3. Click the folder with an downward facing arrow to add the search results to ‘My Places’

4. Right click on the Chicago Parks folder and go to ‘Save As’

5. Save the file as either a .kml in your GIS_Data folder.

Make a Map of Chicago

6. Open a new ArcMap blank Map.

7. Right-click on layers and go to ‘Add Data’

11. Go to Geoprocessing and open ArcToolbox.

12. Go to Conversion Tools > From KML > KML to layer.

13. Set the Input to the KML file in your GIS_Data Folder

15. Click OK. You should see a series of yellow tacks with the park names from Google earth populate your map.

16. Change the symbology to something other than the tack.

17. Go to layer properties and turn off the labels, or change them to a smaller typeface.
