Just a note to let you know that Oz posted my tutorial on "Creating Multi-Segment Raster Topo Maps with Moagu":

Comments, additions or corrections welcome.

A couple of notes for Oz to add/correct:

1) I saw one typo I made:  "For California, be look on the right side".  The "be" should be deleted.

2) I would add the following new paragarph to the end of the introduction: "Another limitation of the raster maps created with MOAGU is that when zooming in very rapidly my Garmin occasionally crashed (3 times during an all day hike).  This caused no harm to the Garmin or the data I was recording.  Leszek has seen this also.  Presumably it is due to a subtle bug in the Garmin firmware.  I'm not sure whether it has been reported, but I doubt Garmin would be interested in fixing a bug that would potentially decrease sales of their own maps.  The workaround is simple--don't zoom immediately after zooming.  The problem usually happened when zooming a split second after the previous zoom.  I found that holding the zoom button down until close to the 500 foot zoom level didn't create the problem, so I could easily and quickly get to the approximate zoom level I needed."

3) To the end of the "Plan Your Maps" section I would add the following sentence:  "For an upcoming map of the Southern Sierra I am working on (all in the California database) I decided to make my segments with the same coordinates as existing USGS quad maps and give each downloaded segment the same name.  This will make it easier to load one topo, and the fact that after re-projection the segments are about 70 megapixels means they are close to the optimal size"

4) Move the sentence "Missing tiles are due to either a bug in MOAGU or a problem with cgsmapper (haven't pinned it down yet)." to the top of the section "Check Map in MapSource for Missing Tiles and Reprocess as Needed".  This will make it clearer why you are checking for missing tiles.

5) You may want to add the caveat you put on the Coyote Buttes Raster Topo page to the Joshua Tree Raster Topo page:  "The map is slower than normal vector maps and only visible when zoomed in to 0.5mi + on highest detail."
