If you check the help file for G-Raster, it has a link to a page that lists a whole bunch of programs that can georeference an image and convert it into a GeoTiff or similar format that G-Raster can use directly; you cannot do this directly in G-Raster. As you've found, the GeoPDF to GeoTiff convertor only works correctly on GeoPDF files. I use PDFCreator to export PDF files in TIFF format; if you look in the options section, you can increase the dpi of the output, which might improve the output quality.

The FS raster gateway has a site with links to GeoTiffs for most of the National Forests in the US; you might take a look to see if the maps you want are there (looks like they have two maps for Shasta-Trinity). I've run several of these through G-Raster successfully.

For clean graphic raster maps, a raster-to-vector polygon converter is probably the best approach. Standard Moagu maps break a raster map down into points, not polygons - best quality, but unless the map is mostly white, very slow. BMap2MP will do this; command-line, but Moagu has a built-in GUI front-end that simplifies the project. Will take some significant work to get the best results; there's a tutorial at GPS File Depot that describes the process for a nautical chart.

MapWel will also do raster-to-vector conversions, quite nicely, and also let you create your own vector-based maps. Non-standard .img files make it more difficult to install in BaseCamp/MapSource for transfer to older Garmins; for newer Garmin models, you can just copy the .img file to your unit.

Haven't tried it, but there's supposedly a free program called ocad2img that can convert the maps directly.

A GIS program (like the free MapWindow program, http://mapwindow.org) might be able to help you with this. It has a tool that lets you clip any shapefile with another arbitrary polygon shapefile. You can also load in a raster map layer as the base, then load in multiple vector shapefiles on top to compare, and delete features that you don't need.

Well, it turns out that DNRGarmin does upload waypoints to the Garmin 62s, but the Garmin in stand-alone mode can't find them (not on the list, and don't show up in a spell search). If I plug the 62s into a computer and run BaseCamp, the uploaded waypoints do show up.

Yup, you're right - only the current track was downloaded. All archived and named tracks stayed on the unit. Uploading named tracks does work, though.

DNRGarmin (v. 5.04) does sort of work with newer models, but appears to be a bit buggy in the current version. Just tried it with my Garmin 62s, and was able to successfully upload and download track data. Waypoints don't seem to be working, though; when trying to download waypoint data, nothing happens, and while it tells me that it successfully uploaded waypoints to the unit, they don't show up on the unit.

You can stop logging track points by going to the Setup menu, choosing Tracks, then setting Track Log to Do Not Record. But there's no way to stop the Trip Computer from running - the only thing you can do is Reset Trip Data, which resets all the fields. You can't just reset a single field, either. Dumb, I know.

I downloaded your KMZ file, and converted it into a tiled KMZ overlay using my utility program G-Raster. You can download it here:

http://moagu.com/jerseycounty.kmz

Just copy it to your Dakota's CustomMaps folder, and enable it from the Maps Setup page.

You can download G-Raster here:

Most G-Raster features are free (including conversion of GeoTiffs, raster files with worldfiles), but tiling of KMZ overlays only works for registered users ($5).

Try using MapSet Toolkit to install the maps and TYP file into MapSource/BaseCamp, then upload the maps to your Garmin. SendMap has been hit-and-miss for custom TYP files for me, but the MapSet Toolkit approach had always been successful for me.

The Sierra raster files were created with my Moagu utility (http://moagu.com) using the original data format, which only works on the Garmin 60C(S)x/76C(S)x series and some eTrex models; they will not work on newer models (Oregon/Colorado/Dakota/62/78 series). Vectorized USGS topo maps using the BMap2MP utility in Moagu will work on these newer models; see http://moagu.com/?page_id=9 for links to some sample maps, and screenshots from my Garmin 62s.

I know that Rich Owings of gpstracklog.com is working on a review of the Magellan Explorist 710, and you might want to hold off on a decision until that comes out. The 610 model (same as the 710 except without a detailed road map) comes with a camera + microphone for audio/video recording, a full set of 1:24K equivalent topo maps for the US, built-in 3-axis compass, paperless geocaching, a large touchscreen that they say is sunlight-visible (and which from photos looks like it might have a better interface than the Oregon), and a programmable hardware button for quick access to one function. Plus support for Magellan's RMP format, which lets you put scanned raster maps and aerial imagery on the unit (Google "TritonRMP" and "TritonRMP Helper" for free tools that let you convert scanned imagery into that format, with no limits on the number of maps except for the unit's memory). All this for less than the Oregon 550, or the Oregon 450T for that matter.

I'll certainly agree that data entry is a lot easier on the Oregon than on the 60Cx; 62s is an improvement over the 60Cx, but still nowhere as easy as the Oregon. If you switch profiles on a regular basis, I can see the advantage - I don't, so it wasn't a major factor for me.

But I stand by my conclusions. Yes, I was aware that you could change button order on the Oregon, and that didn't make a difference; still too much of a pain to perform basic tasks. Maneuvering through multiple screens to perform basic tasks was a non-starter for me, as was the mediocre screen visibility in daylight. And don't get me started on track recording/management (which still sucks on the 62S, BTW). Throw in crappy WAAS reception, lousy distance/elevation change tracking (which they keep fixing and then breaking again), continued restrictions on Custom Maps, etc..

There's no arguing taste, obviously (though I know several people who disagreed with my Oregon review, and now think the 62S is better than the Oregon for most people). While I don't think the 62S is perfect, it's a huge step up in usability from the Oregon in all aspects except data entry. If you can, find someone with an Oregon and/or 62S and see if you can borrow it for a while; that's the best way to figure it if it's right for you. I bought the 62S, and am keeping it, but you'll have to pry my 60Cx from my cold dead hands.

You can pick up a Garmin 60Cx at Amazon these days for the same $169.99. Actual high-sensitivity, large color screen, bullet-proof.
