satelite topology maps of lakes

2. Download the aerial and/or topo data from a
free MS server. You can get down to 1 meter
aerial - enough to see a boat on the water.

Is there a URL to get aerial/topo data?

The software he listed downloads it for you. I just tried it, but I have
serious doubts about its accuracy. I read hte latitude and londitude off
the GPS in both of my boats sitting in my driveway in Yuma Az. I plugged in
that info, and it came up centered about 15 miles to the west.

I have not had that experience.
For me, it has always been right on - within
40 feet or so. Check to insure that the data
type of your GPS & the program are the same, etc.
I'm sure it's a setting, not an inaccuracy of the program

BTW - be sure you are "moving" to get an accurate
GPS reading. I have gotten inaccurate GPS readings because
I was sitting still! No kidding, you need to be walking around
to get good readings:-)

15 miles?

A couple hundred feet I could understand, but 15 miles?

I have two boats sitting in my driveway. Both have GPS maps, and they both
showed the marker on my street on the map. I read the latitude and
longtitude down to the second. They were within two seconds of each other
either way. Thats what I entered in the software.

Sounds like you may have a little conversion
error.

Here are a few links to verify the conversions:

http://www.geology.enr.state.nc.us/gis/latlon.html

What are the readings on your GPS?
If you do not want to post them to the public, then email the readings
from your GPS (s) and I will download the data & see what I get,
then email it to you.

Bob, is it possible that your GPS is reading in decimal and the program
reads in "minutes" ( maximum is 60 ) of a degree? Most GPS's have both
settings. I was verrrry confused at a known location one time...trying to
track it on a computer map...when I discovered what the differences were.

If you have readings above .60 or you have readings of .878 or some
partial decimal above .60 you have it set up for decimal fractions instead
of fractions of minutes.

It is easily adjusted on the GPs and perhaps on the program too. RichG

regarding your comment

"CAUTION: download a little utility that converts the different formats of
lat & lon - you "WILL" need to do this simple math from time to time."

Where might one get this little utility? It did not appear to be on the
JMCOX site.

Here is all you need to do:

1. Go here & download a shareware program
http://www.jdmcox.com
Full Install of USAPhotoMaps 2.25 .... Download Here


2. Download the aerial and/or topo data from a
free MS server. You can get down to 1 meter
aerial - enough to see a boat on the water.

When you first start the program, just enter a starting
lon & lat, then select 8 meter resolution, then type in
"p", then "f" to fill the page (that is, download) a full screen
of aerial that can be viewed at 1, 2, 4, or 8 meter resolution.
Hit "t" for topo.

The software is there to connect your GPS to your PC.
If you have a GPS that connects to a PC via a cable, then
this software is all you need. I typically burn a lake topo & aerial data
to a CD - then use that in the field.

CAUTION: download a little utility that converts the different formats of
lat & lon - you "WILL" need to do this simple math from time to time.

Hope this helps someone.

I live on a small lake and heard that some company sells detailed
depth charts based on radio satelite imaging. (I want to use my GPS to
find the correct spots on the lake).

Please advise,

Thank you

You do not need a URL.
The program "automatically" goes to the Microsoft
server & downloads either the Topo or The Aerial data
you requested. You do not need to do anything, except
download the program, install it, enter a starting lat & lon,
select topo or aerial, the image scale (that is, 1m to 64m),
the tell it to fill the screen on your PC . Your screen is
displayed as a matrix, then each little square is automatically filled.
If you have a problem running it, post it here & I'll try & answer
it.

Awesome Program. All my GPS wapoints are right on. Best view I've seen of
them as well. Only problem is I would also like maps of Canada as well, due
to my proximity to the St. Lawrence River. Anyone know where to get these.

Again, Awesome Program.
