Example of the Collect Events model inserted into the poster
This poster shows the maps and pictures of geoprocessing models used to create the data for each stage of the analysis (click the image to see a detailed version of the poster[1.35 Mb]).

What: This poster shows the results of a hot spot analysis, but it was also designed to show how those results were reached. Pictures of the geoprocessing models are included to show the steps in the analysis. In many cases there are several tools in GIS that produce potentially similar looking results, but with critical differences in terms of either assumptions about inputs or how input data are processed. Analytical maps are often intended to be used by subject matter experts and excluding information about the methods used to achieve the results can impede their ability to assess the analysis.

Why:To help readers understand the analysis methods. How: The poster above shows three models. To include them, we created screen captures by using Alt-PrintScreen. For larger models, the ModelBuilder application has an export option that can create bitmap images of the model. The key to success in creating a screenshot or exporting a bitmap is to have sufficient resolution to look good on a printed product. Here is how we added the models to the above page:

  1. Set your monitor’s screen resolution as high as possible; we used 1280x1024.
  2. Open ModelBuilder with your largest model (in terms of number of elements) -- for this page, it was the model at the bottom right on the poster.
  3. Resize the ModelBuilder Window as large as possible while maintaining the same porportion of the model diagram.
  4. Use Alt-PrintScreen to capture an image of the window. Using just PrintScreen will capture your whole computer screen -- you only need to capture the window that the model is shown in, so use Alt-PrintScreen instead.
  5. Open the Paint application that comes with Windows and use Ctrl-V to paste the screen capture into Paint.
  6. Save the picture to a .bmp file. Using the .bmp format will preserve the colors in your model. Using othe formats may cause a shift in colors.
  7. In the ArcMap page layout, insert the .bmp file as a picture and move it to the location desired.
  8. Next, verify that it looks good by first zooming to 100% -- if that looks good, test the resolution by creating a print version of the page. This is your final verification that the picture of the model looks good on the page.
  1. If you need to get a higher resolution image of your model, use the ModelBuilder export option to create a bitmap image of the model -- in this application you can set the resolution (dots per inch, or DPI) so you have more control over the resolution.
  2. If you need to share the .mxd file (as was the case with this map), edit each inserted picture’s properties and checked the “Save Picture as Part of Document” option. This will make for a larger .mxd file, but you can then store it in a ZIP archive to get a higher rate of compression.
PDF Resolution posted by Ann Zdroik on Sep 26 2007 12:56PM
I know this map was made to be printed. But I can't help but notice that the PDF file size is 1.2meg, but the resolution is really good. Can I just ask what dpi was used and did the screen captures cause problems when exporting?

We used 300DPI for the export resolution. The images of the models were reduced by about 66% (each one varied a little bit). That means the 96 DPI for the 96 DPI became about 128 DPI, which is well below the 300 DPI specified in the output. Hence the diagrams did not heavily influence the overall output file size.
