I've used USA Photomaps for several years, and have always been impressed with
it's functionality.

I've recently started a project in Adak, Alaska, in the Aleutian islands.  When
I try to go to the address "Adak, AK", I get the error message:

N 51.902598
W -176.621558

is outside the USA.

Although this area is remote, it's within the USA.  There are USGS quads
availble for this area.  Is there anyway to get access to this area?

Thanks,

Sorry about that. I'll see if I can stretch the limit I set to include Adak.

Adak, AK isn't on TerraServer. So it can't be in USAPhotoMaps. I hope you're

Just wanted to post that I've had some success with USAPM in Linux under the
WINE emulator.  I have a mighty fine laptop from work that unfortunately had the
anti-theft garbage/chips in it.  I tried dropping
the work drive out of it, put a clean hard drive in and it simply won't load
Windows.  When I dropped a Slackware 12.2 CD in, the thing just let it
load Slackware plain as day and everything on the Fujitsu laptop works.
USAPM accesses the online maps just fine and dandy.  To access the USB GPS
receiver/antenna and the TNC from the Kenwood D7A(G) one simply
make a link in the /.wine/dosdevices linking the USB port where the devices are
fround.  In my case /dev/ttyUSB0 is the GPS and /dev/ttyUSB1 is
the radio.  I link them to the com ports in USPM where I want to use the
devices.  Works really well so far but I haven't explored everything yet.
I can post further details if anyone is interested.  I'm not at that
particular laptop now otherwise I'd simply post it.

I have a TNC-X and I believe that will work too when I get a chance to play
with it.   Worked O.K. under XP.

well i am trying to find my property which was given to me  i have the parcel
number and the lot number and it is in pinion hills ca . i called the san

answer of where it would be located . what type of gps unit  could i use to find
my land without hiring a surveyor.

A cheap gps.

But it will only tell you the latitude and longitude of where it is, so you need
to know latitude and longitude of the boundaries of your land before you bother
any further. A parcel and lot number isn't enough info. They probably expect you
to hire a surveyor.

A GPS receiver will only be useful to you if you have a latitude and longitude. 
You are unlikely to find this in any of the land records.  However, most states
and/or counties provide land ownership records online.  If you can find these
records, they will give you an address or at least a street name.  Then you can
use USAPhotomaps or Google Maps to find the property on a map.  Once you have
that, you can get directions from Google Maps or the GPS coordinates from
USAPhotomaps.

Do some searching for their online property records.  Or call the courthouse in
that county and ask them where to find them online.  These records used to be on
paper in large books in the courthouses.  That is why the often refer to "Folio"
(the book number) and "Page" or similar.  There are other terms for finding the
property on the map page, like "Grid" or other.

The land use office is not the right outfit to help you.

Rick

A recreational grade GPS mapping is not a substitute for a professional
survey. On a large parcel, a good GPS mapping may help you find existing
markers such as iron pins or concrete monuments that have been set by
previous surveys, but if you are trying to establish legal boundaries
for the bank or whomever, or are having encroachment issues with
neighbors, you will need a professional survey.

I have used the software programs Manifold GIS and USAPhotomaps to
create pretty good field maps and waypoints for my Garmin Etrex Legend
GPS. The GPS then guided me to within 10 - 15 feet of marks that had
been set many, many years ago in the heavy spruce undergrowth of coastal
Maine.


For Pinon Hills and San Bernardino County, this link and put in your
parcel number.

Is there any way to reduce the size of the pop-up when I display Track Data? 
It's about 2 1/2 by 4 inches.  While I can move it, it still covers some of the
map area that I could use.

Thanks   Lou

No, sorry. It should only leave a 2 1/2 by 1/16 inch vestige if you move it to
the bottom.

I really like the ability to add pictures to waypoints.  Lets me confirm my
memory.

One thing that's somewhat bothersome is the fact if I inadvertently hover over a
waypoint, the list opens and will not close unless I open one or more of the
pictures.  Can't just click "Close" and have it go away.

Not a big deal - I like the picture attachment feature a lot.

Lou

Thanks for the feedback.

Hello all,

I'm new to this group, but a long time user of USA Photomaps. I've used the
program sucessfully with my old Magellan 315 and Sportrak Map. Recently I
upgraded to a Garmin Colorado when my Sportrak crapped out on me.

The problem I'm having is sending and recieving waypoints. If I use Garmin usb
mode in the program and spanner mode on the GPS the two communicate to a point.
I can plot my current position in real time or import tracks, but as I said no
waypoints either way (no error messages either). If I try any other settings on
the GPS I get the "Your Garmin doesn't seem to be attached" message.

Has anyone had success sending and recieving waypoints to a Colorado?

Thanks, Mike Mahoney

I don't have a Garmin Colorado, but I think I found how to fix your problem (by
reading the Colorado Owner's Manual and reading the relevent pages at
www.garmin.com.

The Colorado Owner's Manual says (in Specifications in the Appendix), that it's
Interfaces are Garmin Proprietary serial, USB mass storage device, and NMEA
0183. And at
http://developer.garmin.com/web-device/garmin-mass-storage-mode-devices/
you can read about the format that's used. It's no longer the USB format older
Garmins used.

What you should do is connect your Colorado to your computer (via USB), then go
to My Computer in Start (at the lower left of the Windows screen), and look for
the Garmin that should present itself as a drive or folder. Then copy whatever
you want to your computer. If you send me examples of waypoint, etc, files, I
can make USAPhotoMaps able to read them.

Does anyone use USAPM with a GPS as a moving map display?  I have always wanted
to do that.  I even have a bluetooth GPSr that I could use, but I've never
gotten it to work with USAPM.  I was just curious if anyone else finds this
useful.  I figure with the netbook computers this would be a lot more
convenient.

Rick

From the GPS menu help file:

/USAPhotoMaps can show position with a bluethooth connection to a GPS
receiver, because all bluethooth GPS receivers emulate a serial port
connection (just like a USB/serial cable). You'll have to find out which
serial port the bluethooth GPS is using in Windows' Device Manager. Most
of them require that you set a specific BAUD in the connecting program
(USAPhotoMaps)./

Hopefully your unit can put out NMEA or GARMIN protocol which you select
in the GPS protocol dialogue. Set the protocol, serial port, and baud
parameters, hit the space bar, and you should be in business.

Works great with my eTrex  Legend and an old laptop with a serial port.

Works great, I am looking to buy a net book for the very same reason.

I'm curious, what do you use it for exactly?

Have you ever used it for car navigation like a GPS?  I have thought of doing
that, but my laptop is a 17" and not very practical.  I would be interested in a
netbook, but their screens are very short.  I guess I could turn it sideways,
but still the text on the road display is very tiny and I would crash while
leaning forward to read it!

I've heard that some of the netbooks are pretty good on battery consumption, so
I guess you could carry one around like a large, heavy GPS if you wanted the
larger display.

Rick

Thanks for the advice, but that is not my problem.  Serial ports under Windows
has gotten more and more complex so that any given program may or may not work
with any given serial port device.  It is possible that I am doing something
wrong, but I have tried all the conventional stuff and I still can't get USAPM
to work with my blue tooth GPSr.  I can make it connect to any number of
programs, although I don't know that I've tried that with my Vista laptop.  When
I have some free time, maybe I'll work on this again.  Once I have a working
GPSr again...

Oh, and there is the problem that many Bluetooth stacks seem to be pretty poorly
coded.  The Blue Soleil driver crashes quite often on my Win2k machine.  In
general, I have found Bluetooth to be a blue in the real.

In addition to getting USAPM to use the COM port assigned to the Bluetooth
serial port, don't forget to set the GPS to use NMEA protocol.  I don't
have a Bluetooth GPS yet, but I believe USAPM only does the moving map
thing with NMEA input, not the proprietary protocol.

Barry

Wow!  I bet Doug Cox is pretty proud of that!  I'm glad that this program has
found such an important use.

I only wish we could get some more current maps.

I experience both the line corruption and X's problem frequently in Topo mode
and occasionally in Photo mode. It's frankly maddening. I'm a long time
registered user (been using it at least 8 years) and still frequently use it.

At the moment my USAPhotoMaps directory is over 30 GB in size. I have it on a
number of computers, but my primary workstation is a Win2K box running an Athlon
XP2100 overclocked to about PR 2600, 2 GB of DDR, three 7200 RPM 500 GB ATA100
drives, an nVidia 7900 GS 512 MB AGP vid card driving a 30" monitor that runs at
2560x1600 High Color mode (16 bit). I have more powerful boxes, but this one has
8 years of comfortableness built into it and it runs like a top. My internet
connection is two T1's with BGP routing and I'm one 100 MB switch  from the
router with no latency or packet loss.

The X's problem has been happening more and more frequently for the past few
months. Up until today I could always fill a 4 meter screen without any problem
other than having to wait 10 to 15 secs for the last box to fill on a line, but
for the past couple of days the X's have started showing up on the 4 meter
screens. I ALWAYS run it in maximized mode and usually in focus. For the past
few months I have not been able to fill 6 and 16 meter topo screens without
getting X's at some point. Today it started happening in Photo mode on a 1 meter
screen. On my monitor a 1 meter screen is 13x8 boxes. I just tried to fill a 2
meter photo screen (16x26 grid) of Salt Lake City and it got to the last line
and X'ed out. I don't know if was mentioned, but it just hangs when it is X'ed
out and you have to manually abort the fill to get back control. After aborting
the fill and restarting, it X'ed the last 6 boxes of the line. The third attempt
filled those last 6. I just changed it to an 8 meter topo and tried to fill it.
It only filled 37 boxes of the first 6 lines (that's less than 25% of the 156
boxes) before it started X'ing out the rest. Now it just happened to be 12:59
and about 59 seconds local time (I have a server synched to a stratum 2 time
server that chimes the hour and half hour) when I clicked the "Stop Downloading"
button and as it hit the hour I got the browser window popup about the server
being too busy, etc. and that has been happening every time on the hour and half
hour for the past month or two. Attempt two resulted in the first line being
filled in and then X'es, attempt three filled the second line and then got X'es
and every subsequent attempt fills the next line and then X'es the line after. I
zoom to 4 meter topo mode and this behavior continues for two lines then files
two lines and X'es, repeats and finally fills the remainder. It's made
USAPhotoMaps virtually unusable for unfilled areas.

Onto corruption. It occasionally happens with 8 meter topos, but almost always
occurs with 16 meter and larger screens for at least one line and sometimes as
many as 4 lines. It usually happens within boxes of the right edge, but
occasionally hits more. Occasionally it roaches the entire line for the zone and
sometimes I can recover from it with just CTRL-DEL on the screen where it
happened. Once in a while it so completely fux0rates USAPhotoMaps that I have to
go into explorer and manually delete the row or the program crashes as soon as
it tries to load that row. Fun wow.

So I have three issues that have made using this wonderful program somewhat less
than enjoyable these days. I had been regularly checking for updates hoping the
X'es thing was a known attempt by the terraserver to prevent USAPhotoMaps users
from mass downloading data, but I have no idea what's causing all these problems
now. The on the hour and half hour busy popup abort is just bizarre, I can't
imagine why that is happening. I can't pretty much live with anything, but the
X'es. The X'es have kept me from being able to effectively add to my dataset and
they just drive me crazy!

It still seems to download fine on my small-resolution laptop computer
(1280x800). I wouldn't be surprised if Microsoft were making the download
process less than enjoyable for power users.

I wonder if an optional short (maybe adjustable) delay of some milliseconds
might help the X problem. Maybe a configurable value for how many requests are
sent out as a batch at one time.

I run some websites that occasionally suffer from mass automated downloading and
have programmed in a number of methods of detection and abatement for those
situations in order to ensure server availability. I have to wonder if M$ has
done something like that with the terraserver and/or I have somehow gotten onto
a greylist that triggers them.

What is the USER_AGENT string that get sent with the request? How about a
configurable USER_AGENT string, even if only changeable by hand in the USAPM.ini
file?

A logging debug mode would be nice to gain more insight into what is going on at
times.

I'm not sure if I have seen the same problem as you or not.  I sometimes see
picture quads either not show up (X's) or other times corrupted data displaying
black or distorted.  The corruption seems to be infrequent and I correct them
manually by deleting just that quad and loading it again.

The X's seem to happen when I switch focus away from the program, or more
accurately, when I switch it back.  The entire time it was running, not in
focus, it was filling the grid.  But when focus is switched back to USAPM it
starts displaying X's until the end of line or sometimes for the rest of the
grid.

I don't know that adding a delay would help any of these problems.  I don't
think it is a matter of too many requests at once.  The server this is going to,
I am sure, handles many thousands of requests a second or perhaps millions.  The
couple of dozen at a time from USAPM shouldn't be a problem.

On the other hand, the focus problem is likely something with USAPM.  But I bet
it will be a hard problem to find.  That's usually the problem with something
like this, finding what is going wrong when the act of observing it changes the
problem or makes it go away.
