When posting maps on this wiki, its a good idea to post both the map itself, and a separate page that has metadata, and multiple versions of the map (e.g. PNG and PDF).

An example is the Elevation map for Carmel River Watershed. It has:

  • [[Carmel River Watershed: Map of Elevation|A main page with meta data and links to multiple versions]
  • ...

There's probably many ways to do this, but here's some ideas, starting with ArcMap:

  1. Make map:
    1. From ArcMap, Print your Layout to an Adobe PDF file
  2. Upload map:
    1. Click 'Upload file' at left of wiki window. Upload file. Format and size is limited. After you upload it, the Wiki will tell you how to link to it.
  3. Link to your map:
    1. Edit the page where you want the map to be linked. Paste the link from above into the page.
  4. Create a thumbnail of your map
    1. Convert PDF to PNG (The Wiki automatically creates thumbnails from image files like PNG and JPG, but apparently not from PDF.). Open PDF, and Save As PNG.
    2. Shrink PNG file to less than 2MB (the current maximum file size), using something like PhotoShop.
    3. Or Save map as small PNG file (<2MB) from ArcGIS
    4. Upload PNG to Wiki
    5. Create a link to the PNG in your page, like this 50px. The '50px' patr will tell it to automatically display a tiny 50-pixel wide thumbnail.
    6. Copy the formatting for the links of the existing thumbnails to get a nice, titled thumbnail
  5. Link from thumbnailed image back to original high-quality PDF
    1. When you click on the thumbnail, you'll be taken to the page for the full size PNG, which probably doesn't look as good as your full-size PDF. You can edit this page, and type a link to the PDF. This is not very neat. There's probably a better way. (Perhaps if you map the map in PNG first (with ArcMap), not PDF, the PNG might look as good as the PDF.)
    2. If you exported your map as a PNG directly from ArcGIS, then when you click on the thumbnail, it will open automatically to the full version PNG that is high enough resolution for screen viewing
