Map Making Support / Re: State Plane coordinates?
« on: October 20, 2009, 07:03:02 AM »
Globalmapper makes this trivial. You can open files in any format, change the projection to whatever you like, then export. Maybe overkill for what you need, or maybe you would find other uses for it?

Yes  :)

I have Windows XP in a Bootcamp partition on my MacBook Pro, so I can either boot directly into XP or run it under Parallels. Globalmapper, cgpsmapper and Mapwel are all resource-hungry programs. I saw a significant increase in performance when booting directly in XP as opposed to running windows with Parallels. Also saw less crashes.

But after awhile I got tired of having to reboot my Mac to do mapmaking, so I picked up a Dell Core 2 duo 2.8ghz desktop system with 6GB of memory and Vista 64 bit on sale at Best Buy. In spite of all the Vista complaints, it works very well for me and I have fewer crashes than I had under XP. Eventually I will update to the 64 bit version Globalmapper 11.

That's what I use primarily now. It's nice to have a dedicated machine, because some of the things I do can tie it up for as long as a day at a time. For example, I merged a large number of OziExplorer ozfx3 files of aerial imagery together into one big 5GB map file; that took 14 hours. Couldn't be without my Mac for that long most of the time.

Yeah, I just started surfing through your tutorials.  They are much more accessible than the OSM stuff.

The new version of Mapwel has built-in support for OSM which looks pretty cool actually. Have been meaning to find the time to play with this. http://www.mapwel.eu/osm/osm.html

You will need Windows for this too, but Mapwel is much more user-friendly than cgpsmapper. Downside is that it doesn't support Mapsource. You can load your maps directly onto the GPS from Mapwel, or create a .img file on your computer and drop it into the GPS.

Globalmapper only runs under Windows.... I would be be lost without it.  :)

But same thing for cgpsmapper and Mapwel, which are the two Garmin map compilers available. Seems to me there's a website somewhere that you can submit .mp files and get them compiled online though.... isn't there? I wouldn't want to depend on that for anything more than a very small project however.

There doesn't seem to be much of a push to make Mac versions of any of the tools we use though. Many of them were written as "labors of love" by ordinary users, so porting to a different operating system is not likely to be something they would have the time or motivation to undertake.

I think you really need to run Windows if you are at all serious about mapmaking. For everything else, I use MacOSX.

I noticed the site was down at around 9:00 AM or so on the 15th. There was no response and I got a browser error saying it couldn't open the page. It remained like this all day (I checked a few times) until sometime in the evening when I uploaded the Kauai map. Probably around 6:00 PM?

Have not noticed any problems since then.

GPSr Units / Re: stupid question about my new venture HC
« on: October 17, 2009, 11:41:19 AM »
The screenshots which show elevation contours are no doubt from US Topo and not the basemap. The basemap only shows VERY major roads and boundaries. IIRC, the Venture has 24MB of internal memory. Or maybe I'm confusing it with a different older model? I used to have a Legend C with 24MB.

That will be enough for you to load topo maps of a portion of your state. And that is where GPSFileDepot comes into play (if there are maps available for your area). Otherwise, I would say the Legend Hcx is a much better unit. The card slot will let you load topo maps for a good chunk of the whole US instead of a couple counties in your state like the Venture.

I have used Macs exclusively ever since 1985. But when it's time to make maps, I run Windows. Unfortunately, the tools just aren't there yet for the Mac. Maybe someday, but certainly not yet.

For the past couple hours I have not been able to access the homepage at gpsfiledepot.com. The forums are working fine. Are others also having this problem?

GPSr Units / Re: 60CSX or OR550 Which is better for map making?
« on: October 13, 2009, 05:15:43 AM »
Caveat emptor.... Garmin is now using a different chipset in the 60csx (it is no longer the SiRFStar III which was being used when that article was written) so those tests are probably no longer valid. I don't know if the new chips are better, worse, or the same.... but they are different. Seems to be the luck of the draw as to whether a newly purchased unit will have the new or old chips, and it may be hard to determine which you have.


Garmin Selects MediaTek GPS Chipsets for Outdoor Navigation Devices

Hsin-Chu, Taiwan --May 25, 2009-- MediaTek, Inc., the leading fabless semiconductor company for wireless communications and digital multimedia solutions, today announced MT3329, its advanced single-chip all-in-one GPS solution. This product in mass production has also been integrated by a wide range of Garmin outdoor navigators, the Garmin GPSMAP 60 series

I have only played with the map files which I already had on the memory card and the built-in US Topo. Funny - I had several unused mapsets on the card which I had just re-named to something else while the active map was named gmapsupp.img. Had not updated firmware for awhile until now, and after the update, all those previously invisible mapsets became available which confused me at first.  ???

Here are a couple examples. The screenshot on the left is from my own map with 5 foot contour intervals, TIGER roads and NHD water. The one on the right is from Garmin's US Topo 100k, which has much less detail.

I think I will make some custom mapsets for areas I plan to explore with just enough vector detail in the right colors to enhance the map. Also, I mentioned that tracking seemed broken to me when using the raster images. I just realized that this is probably because I had disabled all the vector mapsets. Will put this to the test in the field when I get a chance, but I'm guessing that tracks are somehow tied to vector maps, and they don't work if you don't have one enabled?

It is very limiting, but cool nonetheless, and if I were buying a new unit I would want this capability. I don't think it will ever come to the 60csx because it just doesn't have the "chops". I made a custom vector map with lots of detail and tested on the Oregon and 60csx. It is really slow to zoom and scroll on the 60csx, but pretty snappy on the Oregon. The processor is much faster in the Oregon.

I just made a 24k USGS topo map of the whole state of New Jersey for use in OziExplorer. It looks really nice at 10 feet per pixel. When I sampled it at lower resolution, details started dropping out. But at 10 ft/pixel you could make a 20 mile x 20 mile (400 square mile) custom Garmin map.

OTOH, I posted screenshots here of 1 foot per pixel digital orthophotography which was great for hiking around and exploring. I could only get a 2 mile x 2 mile area at this resolution with the custom map limits.

Hopefully they will sort it out in future updates and let us make bigger maps, this is still beta software. I use OziExplorer CE on a Magellan Triton and Maestro and have digital orthophotography of most of Southern NJ (over 3000 square miles) at 4 feet per pixel in a single 5 gb ozfx3 file. It zooms and scrolls very quickly.

IIRC, you also have to turn off pop-up blockers for this to work properly...

General Discussion / Re: Routable version of Mapwel on the way
« on: October 11, 2009, 05:10:52 AM »
Obviously you guys have "bonded" with Mapsource and I have not.  ;)  Seems like the main need would be for people with older models which don't have enough memory to hold a full mapset (otherwise you could just drop a gmapsupp.img file into your Garmin folder). You could still use mapsource with another map on your PC and the Mapwel map on your GPS otherwise if you just want to exchange tracks, waypoints, etc.

Mapsource just isn't one of those programs which give me a warm, fuzzy feeling. And now we have raster-based maps on the newer handhelds. They don't work in Mapsource either, so I suppose they will not be of interest?

IMO, if you are considering the purchase of a Garmin GPS then everything just changed this week. Sooner or later you will probably wish you could use Garmin's new custom map capability (see: http://forums.gpsfiledepot.com/index.php/topic,589.0.html) and it isn't (and won't be) available for the GPSMap 60 or eTrex series.

I doesn't matter. You can load them in internal memory if there's enough free space. Otherwise, use an SD card.
