Microsoft Streets & Trips zoom limit in areas with no road map
Maconpane
Just returned from Zimbabwe bush country. Discovered that the maximum resolution is cut to about 50% where Microsoft Streets and Trips does not have road info. I was trying to map some bush roads and trails, and found the limitation frustrating and needless. I see absolutely no reason Microsoft set that limitation. I'd like to continue the project. Can anyone offer an explanation, and perhaps a resolution to the problem... or offer a suggestion for a more appropriate software for the purpose?

Note that I do not care about having predefined maps with any more detail than is currently offered for the area with Streets and Trips (political boundaries, and locations of a few cities and towns), I simply want to be able to record tracks more accurately.

Thanks,
Mac

Coastlines, rivers, etc. are not stored to the same level of detail as for the "mapped areas". This might have something to do with the reason for the zoom limit.

Neither Streets and Trips nor AutoRoute purport to provide mapping assistance outside of their respective territories, North America and Europe. Therefore, Zimbabwe, and the rest of Africa, is categorically not covered. Be reasonable.

Yes, but if there was a way to remove the hard coded zoom limit for unmapped areas, it would open up the software to new uses.

With Garmin MobilePC I can zoom to 30M in Zimbabwe. Mobile PC has a similarly detailed world basemap as Streets&Trips. It shows, for instance, the A5 and some other major roads and Harare Intl airport, etc. It shows some major lakes and rivers. I'm on the road and don't have the time to do a screenshot and post it but if it matters you can probably get someone else here to do one for you.

Glad to oblige. The basemap lists accuracy to 8 miles but you can go down to 120 feet with the zoom before it bottoms out.

Thanks to those who read my post closely enough to understand my question.

Much of my frustration was that my little $100 eTrex had no limitation. Only problem was I had no interface with my laptop to save the tracks. Now that it was mentioned, I think it's correct that the zoom limit set in Streets and Trips is due to the limited accuracy of the minimal mapping (political boundaries, etc.) they do provide for non-mapped areas, probably closer to guesses, with little effort toward accuracy, which would not be a problem for my project, but as was also mentioned, if there were a way around the hard-coded zoom limit, it would sure increase the uses of this software.

By-the-way, Terry, what is the down-side of using the "over zoom" with Garmin PC? Looks like that might be a better product for my situation. I mean, it's not like I'm gonna be looking for street addresses or motel locations in the Tsholotsho bush country. :-)

Thanks, again.

It would be the same basemap as your Etrex. The stated accuracy just means they do not guarantee the placement of items visible below 8 miles. Shouldn't be a downside for your use as you would be more interested in the longitude and latitude - a function of the accuracy of the GPS. Mobile PC also saves tracks which can be viewed in the program and transferred directly to MapSource.

Maybe someone has already created a MapSource map for Tsholotsho bush country listing all the Motel 8 locations. You never know!

Thanks, Terry... and everyone else.

Just ordered Garmin MobilePC from Tigergps. If it works to provide close enough accuracy, I'll order a second, and just ditch the mapping I've done so far with Streets and Trips. It served a purpose, so not totally wasted.

Lesson: should have researched all this BEFORE my trip, eh.

S&T 2010 files can be transferred to MapSource using the Export to gpx function. I'm not sure if the information you need will be included but it is worth a try. You might be able to get some useful data moved into Mobile PC from those files.

@Terry,
Even if it's an older version of Streets&Trips, he might be able to use GPSBabel online to convert the .EST file to a GPX file with the tracks in it. This is a case where the older the version of Streets&Trips he has, the better chance that GPSBabel will convert from it.

@Mac,
If your eTrex is an older version, it should have the ability to connect to the PC using a serial cable. Newer versions of the eTrex connect with a USB cable. Either way, you can use Garmin's Mapsource or Basecamp to retrieve tracks from the eTrex and work with them.
