Iphone USGS topo map navigation app on 03/22/2009 19:57:56 MDT Print View

Just downloaded and started using a new topo app for the iphone called iTopoMaps. Looks like someone who backpacks and programs has gotten around to designing a topo map application.

This app. allows you to download and cache USGS topos on your phone freely downloadable through the phone in advance so that you can use the iphone in airplane mode while in the wilderness thus saving on battery and not need a 3G or cell phone signal. Turns the Iphone into probably the best mapping GPS IMO with no fees to pay for maps.

I used this in Shenandoah today and it worked well. Still no route planning functionality but apparently it's coming. It does allow to create waypoints. I will be testing this more in southern Utah's slot canyons in a few weeks and will post more results. But this app may be what finally justifies my iphone after 8 months of love/hate. Perhaps it be useful to other iphone users

I guess $15 is a fairly good price for a portable USGS Topo viewer. Did you say the topos were free, or extra $ (I'm sure they'll be extra $ once 3.0 OS and App Store pricing restructuring comes out in June)?

I have this app as well. It is outstanding. The topos are free and can be stored on the phone permanently. Many new features. Are coming soon. An update is due out this week. Customer service is excellent. The developer responds right away and has put many of the suggertions from the help forum in soon to be coming updates.

topos on 03/23/2009 06:51:12 MDT Print View

I think the app hits the USGS google topo map server and downloads the image pyramids there. But they are free and will likely remain free. (see http://store.usgs.gov/b2c_usgs/usgs/maplocator/(xcm=r3standardpitrex_prd&layout=6_1_61_48&uiarea=2&ctype=areaDetails&carea=%24ROOT)/.do)

You acquire the topos by tapping the screen while connected to the internet. So it does require a signal initially while planning and also requires some advance planning. But I cached all of Shenandoah yesterday before leaving my house while connected to broadband without any problem ( I have about 12Gb of free space on my phone so that helps). Those quads are now stored on my phone and since I visit Shenandoah very frequemtly they will stay on my phone for my next trips. No memory cards to fiddle with, no extra fee to pay to TOPO or Delorme or Garmin. FREE USGS topo Maps.

iPhone as a backpacking GPS on 03/23/2009 08:20:42 MDT Print View

Thanks for sharing links for the app and topo files! It would be very cool to have access to more (and free) topo maps. I will definitely give it a try.

IMHO, there also downsides with using the iPhone as a back country GPS:

Weatherproofing - the iPhone is less weather resistant than a typical mobile phone. They will not last long in a rain and I do not think constant moisture would be a good thing. Weather proof cases will probably impact touchscreen functionality and screen visibility.

Touch screen - cannot use with gloves. Even w/o gloves, physical buttons are nice on GPS for quick access of routine functions.

Power - you can run the phone in airplane mode to conserve battery life, but you still are going to use the backlight every time you use the device. The display is twice as big as the typical GPS and will use some juice.

Non-replaceable battery - there are some external battery packs for the iPhone, but you would need to leave connected or charge overnight. Probably not an issue for a short trip.

On the plus side, the iPhone has a much more powerful OS and processor. Developers do some cool stuff compared to what can be done on a typical GPS.

Kyle,

It seems that you don't have an iPhone and are quick to dismiss its capabilities based on what you see as downfalls.

Who needs real buttons when the programmers make whatever on-screen buttons they need?

I use an Aloksak when I take my iPhone hiking or snowboarding. Problem solved.

Re: Re: Iphone USGS topo map navigation app on 03/24/2009 07:39:59 MDT Print View

I don't have this app, so I'm not sure. Since the app downloads and internally stores the topos, I'd be confident to say that the app and GPS would work outside of cell range.

Things like the Maps app need the cellular network to stream/load the maps on the fly.

Re: Re: Iphone USGS topo map navigation app on 03/24/2009 08:03:52 MDT Print View

Roleigh short answer is Yes!

That's the beauty of this app. It caches the map in the internal memory. The GPS works without cell phone coverage. And since you have all your maps already stored internally it doesn't matter if you have cell phone coverage or not. The only problem as mentioned before is longevity. I have a hard case for my phone and although it increases the weight a bit, I think it's comparable to an equivalent GPS + a separate cell phone which many people carry anyways. This protects the phone. An aloksak or baggie as mentionned keeps it dry. I normally ue a GPS as a supplement to paper map and compass. This will not change. This is just a better GPS /phone combination. I can see in the future having guidebooks stored on the phone as well as reading material, plant and bird guides that can identify using pictures or sounds input into the phone.

Kyle, I didn't mean to be harsh on you either. It's just great that the programmers were able to get this field-use GPS and topos to work in non-coverage areas.

Yes, the battery life/replacement may be a hindrance, as is using it with gloves.

But then again, this is bringing the iPhone to be the ultimate UL piece of technology (for those who bring tech into the BC). Phone, GPS, email, music, it's so multi-use! And with multi-use, there will be trade-offs.

I'm getting off topic.

I bought it to have free USGS topos on my phone that I can cache and have interact with the GPS location.Even if I dont use it in the field, this is a great trip planning application if I have to change plans at the last minute while on vacation or discussing with a friend where I've been or getting advice from a local person. I'm a bit bias as a cartographer and map lover I feel it is worth much more than any TOPO package. Most of which are much more expensive.

Iphone USGS topo map navigation app on 03/24/2009 12:37:04 MDT Print View

Hi All,

I have wanted to buy an iPhone ever since they came out. I haven't because they were not enough "Computer" and more or less a cell phone. I don't own a cell phone and have never talked on one.

This thread and the fact that a new upgrade is coming out this summer ?? that will give the iPhone a "cut and paste" feature makes it getting very close to what I want.

I would go for a topo map nav app but it would have to be really easy to use. I use a computer everyday but have little real skill with it.

My vision for the iPhone would be to use it like several have mentioned as a replacement for the paper stuff I would need to carry. It would also be nice if it would take the place of a camera. I am not interested in really great quality pictures, just the run of the mill "vacation" type snapshots that could be posted with a trip journal.

Re: Re: Iphone USGS topo map navigation app on 03/24/2009 13:04:46 MDT Print View

It is indeed very nice to finally see cacheable topo maps on the iPhone. However, a tracking feature would be pretty useless because you would have to keep the app open, which would drain the battery in 2-4 hours even with the screen dim (according to reviews of the other GPS apps). You cannot use the GPS while in flight mode, which means you must keep the cellular antenna on whenever you use the GPS. This adds considerably to power drain.

Further, I can't get the MotionX GPS or GPS Kit apps to track while in 'suspend' mode (i.e. tap power button to turn screen off), so I doubt iTopoMaps will be able to either. The app would have to enable background processes to access the GPS, which Apple forbids. That said, my old Pocket PC and Windows Smartphone devices, which did allow background processes, couldn't track while in suspend mode either, so it may be even more complicated than that. Thus, to use tracking, you have to keep the program open and running, with the screen and cellular antenna powered. Not a formula for reliable tracking, and nothing an app programmer can do anything about.

Thus I see the biggest benefit of GPS-mapping phones in general as locating yourself on the paper map without the need to plot coordinates. Turn the device on, find your position, compare it to your paper map, and turn the phone off. This simplifies the process of finding yourself on your paper map, but is still a supplement to a paper map. This also is the best use of the phone anyway, as it would minimize battery drain.

Unfortunately, however, the iPhone's GPS isn't that sensitive; it can take a while to find your location if you turn it off. I was impressed that I was able to get a signal in a pretty dense forest here in Western Oregon, but it took almost 5 minutes to lock. This limits its real-world usefulness as a primary navigation unit compared to the high-sensitivity receivers out there. Hopefully Apple will improve the GPS hardware in the next version, or at least allows GPS access in flight mode.

Don't get me wrong; I would love to have an all-in-one color mapping GPS device. But after 7 years of frustrating disappointments with PDA-Phone-GPSs, I finally realized that the simple, slow processor and non-backlit daylight display in something like the Garmin eTrex series is the only way you're going to get good battery life with today's technology, and the waterproof, ruggedized casing with replaceable lithium batteries with is the only way you will get reliable performance in the harsh conditions in which you would actually need a GPS for survival.

Thus, I broke down in January and bought a Garmin eTrex H; my first ever non PDA-phone-GPS, and the simplicity and ease of on-the-trail use are frankly refreshing. If I want to mark a waypoint, I press and hold a button and press confirm. No powering devices on and off, no turning radios on and off, no removing gloves, no worrying about the quality of the Aloksak zipper.

I do like audiobooks on the trail, so I debated getting an iPod Shuffle and leaving my iPhone at home, but since the iPhone has twice the audio battery life and includes a cell phone for roadside assistance or lucky reception on the trail, I am keeping both the iPhone and eTrex H in my arsenal for now. Besides, it's nice to have a backup GPS in my phone for redundancy. But if I left a device at home on a high-mileage trip, it would be the iPhone, not the eTrex H.

Re: Re: Re: Re: Iphone USGS topo map navigation app on 03/25/2009 06:52:25 MDT Print View

Yes I did. I own both phone and app. I have been making and selling topo maps for a living for the last ten years and using GPS since Garmin first started selling affordable backpacking models in the early 90's. I guess I say this to make the point that I am familiar with the technology and the medium and I think this is going to change my industry dramatically.

It's easy to turn an iphone's cell phone mode off to conserve battery it's called "plane" mode. This leaves the GPS on. So you don't have to be out of cell phone range to test the app. I did test it in Shenandoah National park this past weekend where I was definitely out of cell range. I'll be testing it again this Friday if the weather is not too wet.

It's exciting to see that other cartographers like Tom Harrisson have started releasing iphone versions of their maps. It may be possible for me to hike the JMT with Tom Harrison maps preloaded on my phone this fall.

Have not checked out the unit you mentioned. It looks very promising. I'm wondering whether it can report coordinates in UTM. If it does I will certainly be getting one. It could be very useful for long trip where only a minimal GPS unit is required.

My understanding is that TopoPointUSA does not have a zoom feature which seems quite limiting.

There is also an app imaginatively named "Topo Maps" which does have zoom and will show current location, but that's it. No waypoints in any form. One other advantage is that it's only $3.99.

When you say that "Topo Maps" has better quality scans is that compared to TopoPointUSA or iTopoMaps or both? I am considering buying iTopoMaps for the waypoint bearing feature.

I like the idea of getting a bearing from the iphone and then using a compass to navigate, saving battery life, but still want to be able to read the maps on the screen.

iTopoMaps Help from Developer on 03/25/2009 21:47:08 MDT Print View

I have been interacting offline via email with Tracy Harton and he gave me permission to repost the help he gave me. It might help others.

[me asking]
Hi, I bought your software for my Iphone, but what I would like is to get the Superior Hiking Trail (in MN) and the John Muir Trail (in CA) maps for it, do you know where I should turn next?

Thank you.

[Tracy answering]
Basically, you must navigate to the area of interest, and mark the relevant quads for download. (Tap the grid-icon to enter/leave quad selection)

Depending on your familiarity with the region, this can be easy or hard.

For the Superior Hiking Trail:

Tap the waypoint icon and have it search for "hiking" in MN. It should find a feature for the Superior Hiking Trail at 47.57361N/-90.83611W. You can add a waypoint
at that location and then zoom in on the area. You should see a few dirt roads along the shore, and then a trail that leads off to the west past the ranger station.

You can maneuver around and explore at this point.

To cache this area for off-network access, hit the grid icon to enter quad-selection mode. Double-tap on the screen and it should ask you if you want to download this quad. Do this one for every quad you are interested in. (A progress bar should pop-up at the top. You can pause the download by hitting the right-triangle to improve responsiveness).

Alot of this is streamlined in Version 1.1, which should hit the App store any day now, depending on Apple's famous review process. In 1.1, it will properly display USGS quad names and you can enter them by coordinate. This can be useful if you have a list of relevant quads from a website, for example.

You should be able to do the same for the John Muir Trail, but there will be many quads to cover that long one... ;)

hope this helps,

[later, Tracy adds]
So I did a little more research on the Superior Hiking Trail.

First, it helped to have this up:

http://www.shta.org/Trail/TrailMaps/index.php

The feature waypoint in the database is for the center, around the Temperance River State Park.

I then just proceed to move up the shore, double-tapping and adding quads, until I got to canada. Repeat going south down the short to Two Harbors.

Attached is a screen shot.

I've been working on alternative graphical ways to selection an area for download, but the poor little phone seems to struggle under the load...

[Roleigh responds]
Tracy,

What does downloading a quad do for you? I have downloaded the surrounding quads but not sure what it has done for me other than change the map to being more green.

Can you please remind me of the 5 icons at the bottom of the screen:

Bluebox Clock or Compass Icon:
Red Flag Icon:
Circle Z Icon
Square Gridline Icon:
Circle I Icon:

I can guess some of them:
Circle I Icon: - press for Information
Square Gridlline Icon: press to get into map quad double click mode
Bluebox Clock or Compass Icon: if double clicked can lose zoom and revert back to your house (where're your currently at) icon

I'm not sure I have complete awareness of these icons and what they do/represent.

Also the circle play-triangle icon at top -- what does that bar to the right of it mean or pressing "play"/"Pause" mean.

I looked for a userguide manual on the web page but did not find one. Is there one?

ps -- there is a big thread going on at backpackinglight.com on your software:
http://www.backpackinglight.com/cgi-bin/backpackinglight/forums/thread_display.html?bo=watch&forum_thread_id=19739

Is it okay if I post some of your comments/answers? Or do you want to join the thread? You don't have to be a paid member to join the thread.

[Tracy responds back]

Downloading a quad makes it available when you are away from wifi/cellular coverage. It also saves battery life. If you're in a region of great coverage, or just exploring at home, you do not need to download quads. You should be able to explore pretty much the whole US w/o downloading anything.

Can you please remind me of the 5 icons at the bottom of the screen:

Bluebox Clock or Compass Icon:

locks the map center to your current GPS location. The map will follow you as you move.

Red Flag Icon:

Lookup a feature of interest by name, and optionally add it as a waypoint.

Circle Z Icon

toggle between max and min zoom (instead of using the two-finger stretch)

Square Gridline Icon:

toggle between quad selection mode and regular mode. You only want to be in quad mode if you are selecting quads for download.

Circle I Icon:

access the text settings page.

Also the circle play-triangle icon at top -- what does that bar to the right of it mean or pressing "play"/"Pause" mean.

That is showing your progress as you download tiles. Depending on your internet connection, it can take a few minutes per quad. You can pause/play the
download if you don't want it to get in your way. (Downloading that much data taxes the phone and its slower to respond)

I looked for a userguide manual on the web page but did not find one. Is there one?

I need to get one on there. I've kind of been hoping the new version would get released as it is much more polished.

Is it okay if I post some of your comments/answers? Or do you want to join the thread? You don't have to be a paid member to join the thread.

You can post anything if you think it will help people. I'll go check out the forum now.

Hi everyone. I'm a hiker/backpacker/rock climber/mountaineer, and also happen to be the author of iTopoMaps.

If I can help answer any questions, please ask, or come to www.itopomaps.com. I have already incorporated many user suggestions into the next version.

But, just to answer a few posed, yes you can access maps w/o cell coverage. You can graphically mark quads for download and it stores them in your flash memory. You can use the maps in "airplane mode".

The GPS does work without cellular coverage, although as someone noted, it is not the most sensitive GPS out there...

You can add waypoints by touch on the screen, by coordinate, or by looking features up in the GNIS database. iTopoMaps will then give you a bearing (magnetic and true) and a distance based on your map position or GPS location.

I've been using the device, in the rain, the last few weeks hiking in the Columbia River Gorge. I purchased a smartphone waterproof pouch at REI for $13 that allows you to use the touchscreen/audio in the pouch.

I wrote this app because I personally got tired of $8 paper quads and $100/state map CDs. I find the touchscreen interface to be pretty slick when interacting with waypoints.

In any case, I expect version 1.10 to hit the app store any day now with much better usability and polishing.

Thanks to those who have tried it.

Tracy,

Thank you for the great customer service! Around here, there are many cottage gear manufacturers of lightweight gear that post regularly, and that's what makes these forums so great.

I'm pleased to hear you can access the GPS in flight mode; I remember testing this a few months ago with the google maps application, and was not able to access the GPS when in flight mode, so either Apple updated this or you were able to program around this. In either case, thank you for the clarification. Not having to worry about flight mode whenever I want to access the app will greatly simply things and adds considerable function.

Any chance you will be adding the ability to input waypoint data from .gpx files? I know you've got many features to implement, but I think more useful than tracking at this point would be a waypoint import function for those of us who plan our routes on the computer with programs like National Geographic Topo! I know these things take time, though...

John:

The 3G has been able to use GPS in airplane mode I believe since its inception. I had one, however, that wouldn't give me any location when in airplane mode. Turned out the GPS chip was fried and it was just using cell location when it was on - I took it back several months ago and GPS while in airplane mode has worked ever since with the replacement.
Apparently the GPS chip going bad is quite common on these phones.

1) Potential Storage - Depending on the quad, i'm seeing between 7-11Megs per quad. So for my iPhone3G, that's over 1300 quads if I dedicated my storage for that purpose....

2) Importing/Exporting Quadrangles and Waypoints has been on the list from the beginning, I just haven't gotten to it yet. Unfortunately Apple doesn't provide any easy way to get local files on and off the device, so everything has to go through remote servers/email...

3) As for airplane mode / GPS. I want to clarify that I said maps will work, but I'm not sure if the GPS will send any location events. I have heard that this is an available setting (separate GPS and Radio settings) in Jailbroken phones. Or maybe my phone is broken. ;( A

Applications have basically no control over the GPS and you just get location updates as they come in.

Also, if any of have been following the 3.0 Firmware discussions, the rumors of this summer's update indicate you'll be able to connect 3rd party devices via USB and/or bluetooth. So the prospect of connecting one of those $40 bluetooth GPSes that you can wear on your shoulder is pretty enticing... Better sensitivity and battery life all in one!

Bradly,

That's really interesting; I purchased my 3G iPhone the first day it came out. Earlier this year, however, I had it replaced due to some cracks in the plastic back. Perhaps I had a defective GPS in my early unit, which would explain why it works now!

Seems us Canadians are being totally left out :(

Don't worry, the Mexicans have it even worse! ;-P

I'm not even going to TRY to reflect on the dearth of digital information on trails here in Japan! :-(
