GOAL: Create an isohyet map illustrating mean annual precipitation for the state of Georgia.
PROCESS SUMMARY DESCRIPTION
Copy from R:drive and paste to S:drive this week’s file (Georgia.ai)>GOAL: Create an isohyet map illustrating mean annual precipitation for the state of Georgia>b. Include all map elements>c. Use the Pen and Pencil Tools>d. Know how to Reshape a Path Outline>e. isohyet interval = 5 inches, starting value = 0>f. Data Source = Southeast Regional Climate Center and National Oceanic and Atmospheric Administration> THE LAB: - Open up Adobe Illustrator and opened file (Georgia.ai)>Printed out hard copy of the file and sketched contours by hand as well as determined where labels would go>Back to Adobe Illustrator: Open Layers Window and add a new layer called Contours (NOTE: Location to save all contours and labels)>Begin with the contours and Begin to carefully use the Pencil tool to draw the contours which should be black with a width of 2 points> When drawing the contours with the pencil tool, be sure to break before a turn so that if you have to erase, it is not the entire drawn contour but just until the last lift of the pencil (NOTE: To delete, Edit>Undo)>As you complete each contour then name the group (double click on the sub-layer and type in name under the name box) so you can come back later and label it>NOTE: Countours got really close at close to 0 inches>Save work periodically>Next create a new Layer called “Labels”>Begin to label each contour, midway and any other location on the contour that will help the reader know what contour they are looking at>TO LABEL: >a. Click on Text Tool and click into artboard>Type in the Contour label, ex. 40>Adjust font to myriad pro – size 6>Using the rectangle tool, draw a rectangle around this>Change fill color to same color as the map background>under the layers window – Labs Layer, drag the Path layer to be under the number layer, so that the number can be seen on the contour map>Using the direct tool, click to highlight the “Path Layer” and while holding down the shift key, click to highlight the “number” layer> Select the Object Menu>Group (NOTE: This groups these two layers into one, so that when you move, it moves as one)>Using the direct select tool, move the entire group and position strategically over the contour line to where you are not blocking much any of the other features, precipitation, Rainfall amount>Repeat process for all contours (NOTE: Due to how close the contour lines are for the 0 to 40, at 5 inches interval, it was decided not to label these on the actual map to avoid crowding)>Once done move the Labels layer directly underneath the Contours Group>Click to Lock the Layer>Click to lock all the other layers too (Layers, Scale, Precipitation, Rain Amount and Contours) as they are not being used>Add a new layer can call this Neatline>Using the Rectangle box tool draw a rectangle around the map and remove the fill>Drag to move the neatline to the most bottom layer in the TOC under layers>This allows all other map features to be shown on the map>Make a new layer for the remaining items as above and again add the respective features; North Arrow, Source/date and author, Title and Legend (NOTE: For the legend use symbols, text and pencil tools to complete then put a boundary box around it)>Save File>Before Exporting be sure to check that the file is a Black and White file as requested: >Unlock and click the layers layer to highlight>Using drop down menu remove the fill>Save and lock that layer>b. Be sure to remove the fill and stroke from the contour labels too. However here we are not really removing the fill but rather making it the same color as the background = white>Click on fill dropdown menu>Select Swatch Options Icon at bottom of window>Fill in the information as shown: a. Swatch Name: K=0, >b. Color Type=Process Color>c. Color Mode = Grayscale (NOTE: Drag the scale until it reads 0% to get it to white and where it matches the background>OK>Be sure to check that there is no Color selected for the stroke>Complete for all labels in the same manner>i.e. click on the “path” layer>go to the drop down menu for the fill>select the white fill to match map background>select the no fill on the stroke>Repeat one by one for all labels(NOTE: unfortunately at this point selecting globally will also eliminate the labels from the contours so you have to be sure to only select the path and the various groups> Export File as a Jpeg file>Open up the Jpeg file and adjust any issues with margins>Save in the project folder ready to post to blog>Archive.
