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:
- Make map:
- From ArcMap, Print your Layout to an Adobe PDF file
- Set the page setup to 'Landscape'
- Set the printer to 'Adobe PDF'
- During printing:
- Set the output image quality to 'Normal' for a first try, but then closely examine the end product to check that it has print-quality resolution.
- Important: Give the PDF file a self-explanatory name for general use on the wiki, like 'CarnerosWatershed_Basemap.pdf'. You can't change filenames on the wiki once they are uploaded, so do this now.
- From ArcMap, Print your Layout to an Adobe PDF file
- Create a PNG version of your map:
- Open the PDF file Adobe Acrobat (you probably need more than the free version for this), and Save As PNG.
- Shrink PNG file to less than 2MB (the current maximum file size), using something like PhotoShop.
- Or Save map as small PNG file (<2MB) from ArcGIS
- Upload PNG to Wiki
- 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.
- Note: The wiki software automatically creates thumbnails from image files like PNG and JPG (but apparently not from PDF).
- Copy the formatting for the links of the existing thumbnails to get a nice, titled thumbnail
- Link from thumbnailed image back to original high-quality PDF
- 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.)
- 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
- Upload map:
- 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.
- Link to your map:
- Edit the page where you want the map to be linked. Paste the link from above into the page.
