Geog 353 Lab 8: ArcGIS Layouts and Graphic File Export
Update: 11/6/17
50 points
ASSIGNED: Monday November 6
DUE: Monday November 27

Before beginning this ambrosial lab, you should have the following in ArcGIS:

Our next goal is to create graphic files in .gif format (one of the most common graphic file formats for the WWW). The means to this end is ArcGIS's Layout view, where ArcGIS allows you to arrange your map, add titles, legends, and export your maps to more generic graphic file formats. In Lab 9 you will animate the graduated color, symbol, and dot density maps and prepare them for the WWW. Your proportional symbol maps are not really comparable, but we will include them on your WWW pages as 10 static images.

Lab 8 Goal: Export your various population maps and legends using ArcGIS's Layout feature and use whatever means to get them into GIF format. Your GIF files should have good color, text, and exact sizing ready for animation (in Lab 9).

The Details:

1) As tidiness is still a virtue, create a new folder in your personal directory called GIF_Maps. You should save your files exported from ArcGIS (and eventually your animated GIF files) in this folder.

2) Take a moment to think about where you are going with your maps: the graduated color, graduated symbol, and dot density maps will be animated. The proportional symbol maps will not be animated, but will be included in your pages as a series of ten maps (they are not comparable). All of the following should be decided before you export your maps:

The Layout View in ArcGIS is the means by which you will export your maps, and provides functions for creating titles, legends, etc. Access it by clicking on the small 'page' icon to the right of the icon for your data view in the lower left corner of your ArcMap window.

Start with your earliest population change map, 1900-10. All other layers should be off.

3) Once in the Layout View go to the Layout Menu and change the percent view to 100% to see the actual size of your map. Remember that your map, once exported, should fit on your web page - not too large or small. If the map is too large or small, change the scale (and size of the map) using the plus or minus magnifying glass tool in the main toolbar: this kind of magnification changes the actual scale of your map, so be careful to keep the two ways (layout vs toolbar) straight in your head.

4) While in Layout View go to the Layout Menu and change the percent view to 50% so you can see the entire page your map is on. Take care to use the Layout Menu percent view to change scale in the Layout View, and not the plus or minus magnifying glass icon in the main toolbar - the latter will change the scale of your map and you don't want that.

5) From the Insert menu select Title. Right mouse click on the title and select Properties. Give your map a relevant title (such as "Wisconsin Population Change, 1900-1910") and consider the type font you want to use for your final map. Review the type chapter in the Making Maps book. Keep the same font for your title, legend, and any other text on your map. Position the title in an appropriate place (probably above your map) and make sure the size is appropriate for the map size.

6) Go back to 50% in the layout view. From the Insert menu select Neatline.

TIP: The dataframe shows up on your map layout as a box, probably 8.5" x 11" based on the size of your document. It is the extent of your .mxd file. You can change the document size (say tabloid or poster sized) and the dataframe will change in size. If you select and move the Dataframe, the map will move around. If you delete the dataframe, the map will disappear. Just be careful, and undo if you move or modify the dataframe while working in Layout.

7) While the neatline is still selected (blue boxes at corners) adjust it to fit around your map and title. If you grab and adjust the Dataframe by accident, the map will move: no good! undo! Once the neatline box encompasses your entire map and title, without too much or too little white space around it, right-mouse click on the neatline and select Properties. While in Properties change the width of the neatline box to 1 point and the background to None. You may need to adjust the size of the neatline again a bit.

8) Deselect the neatline by clicking in the white area off the page. Select 100% from the Layout menu. This is the size your map will be on your web pages. If it seems too large or small you can change the scale by using the magnifying tools on the main tool bar, but you will have to also adjust the title, legend, and neatline.

Have your beloved instructor review the size of your map as well as the title, and neatline placement before you proceed. An example of an ok map size (probably on the smaller end of map sizes), title and neatline is below:

The new version of ArcGIS makes it difficult to locate the legend at the exact location on each of the 12 or 13 maps you will animate. This means that the legend will wiggle around in the animation. Not good! Instead, let's just create a generic legend that we can export as a separate graphics file, and place next to our animation on the web page.

9) Add percent symbols after your percentages in your 1900-10 layer, using the Format Labels option.

10) While at 100% and viewing your 1900-1910 map: from the Insert menu select Legend. Just hit OK for everything: you can go back and adjust details later (by right-mouse clicking on the legend and selecting Properties). Move the legend below or to the side of your map. The legend will probably be too large. Grab the corner of the legend while it is selected and drag it smaller.

11) Double click on the legend. Under the General tab type Percent Population Change or add your state name: Wisconsin: % Population Change (you can also put the state name on a separate line, so a two line title). This will be the generic title for all 12 of the population change maps. Hit OK.

12) Right mouse click again on your legend. At the bottom of the Items tab in Legend Properties click on the Style button. This allows you to change the arrangement of the legend. Use the Horizontal Single Symbol Label Only option, as it gets rid of the layer name and data column header (such as chg_00_10) from the legend, while leaving the generic title we just added.

13) Move your legend so no other elements on the page are interfering with it. Hit the Print Screen button on you keyboard. Open up Paint should be under the Windows Start Menu). Create a new document then paste. You should see your legend, with a bunch of other junk. Grab the Select tool and draw a box around your legend, getting rid of junk but not cutting too close to the legend. Hit Crop to remove all the crap outside of the area you selected. Then Save your file as legend.png or a jpg. Open the legend in Firefox: File then Open File... to check size and how the legend looks... something like this:

Now get your maps out of ArcGIS. You can export the maps, but the best quality in terms of color will probably come from using the Print Screen method.

14) Make sure your layout size is 100% and that your map, title, and neatline are centered on the page with no interfering menus or other items. Print Screen and again go to Paint and paste.

15) Use the select tool to select exactly on top of the neatline in Paint then Crop. If you leave even a bit of extra space on the side, or are on the inside of the neatline, your maps will wiggle around when animated. Save as... a gif file. Give the file a name that makes sense: wi1900-10.gif and save the file in your GIF Maps folder.

TIP: If you find a file extension (.eep, .pip, etc.) you are confused and/or amused by, you can try and find what kind of file it is at one of the following sites: FIL EXT or or just Google the extension.

16) Add the image to one of your HTML pages (or open the file with your browser) and critically examine it.

Export the rest of your maps...

17) To export the rest of your maps: turn off the 1900-10 map and turn on the 1910-20 map layer. Change the title to reflect the years of this layer's data! You might have to retype the title (I think you only have to do this once). Make sure to not move the title at all, and to change the years with each subsequent layer.

18) Export the rest of your maps - however worked best for you. You must repeat this process for the rest of the map types. In total, a whole mess of exported maps:

Next: Animating your exported maps.
