Sounds like an ideal task for GIS. I use ESRI ArcView/ArcMap and the kinds of data access and queries you're describing are pretty common with those software packages. The problem is they're too expensive to use for other than business apps. You might still look into ArcReader (free version) or similar technologies though just in case. ESRI GIS I think the ESRI shapefile or coverage format might be the answer to your data needs. There's tons of that data out there. Here's a good exampleGeo Community. Hope it helps..

Hey after searching forever (long story) I finally bought an IFINDER unit today and am anxiously awaiting its arrival. I have every indication it will be a great buy. At only $125 for a mapping unit with unlimited memory potential (MMC & SD), WAAS, and altitude, it can't be too bad. I saw Lee say the unit could not download trail data. I downloaded the manual and looked it up. The manual says if you put the unit in ADVANCED mode you can save the trail to an MMC card as a .USR file. Doesn't OziExplorer and other software read USR files in their native format? If not, then I'm certain I saw somewhere how to convert and then import it. Bottom line and having not done it myself yet, I still think it CAN be done. And I'm not calling Lee a liar or anything because he might be bigger than me. EDIT - I found a pretty good site you might be interested in. GPS Nuts I-FINDER We should start a thread on here for I-Finder/Lowrance users. There doesn't seem to be many out on the web and I think we could provide some positive info on the units. I'd like to know more about MapCreate and the new MapCreate Topo edition, cables, PDA connections, software apps, etc. (Pardon my rambling on as newbies tend to do...)

Just in case you guys and gals didn't already know about these... You might try NADCON and CORPSCON. I use them for work (engineering) a lot and they're pretty handy. Simple little free apps put out by the USGS. Just do a google and that'll set you up.
