The T2 doesn't interleave the GPS NMEA data into the KISS stream either. Not enough memory. I think the TT4 does now but only in TEXT mode.
I added a GTRANS inside my T2 for the purpose of supplying NMEA out. I think I documented it on the T2 WIKI as well. Now the serial port supplies GPS data (Garmin Protocol), a PC interface (KISS) and NMEA. I built a 3 headed serial to support it as well. It works as planned. I shuld be able to exchange the current GPS (Garmin GPS V) nd just continue on like nothing happened. actually I might just throw a mouse type on and forget about it but then I wouldn't have maps when the lpatop wasn't present.
That is excellent news. I did override the purger already. I found that information in an older post.I saw this embedded in the Digest version:The 2GB report was reading the wrong numbers somewhere. I currently
The topos are based on maps that were done up to the 70's or maybe a bit later. The aerials are newer and the URBAN aerials are even newer but not available for everywhere. They also have better resolution. They have the 1/4M per pixel. I use the topo for the layout of the land more than for street anyway. And the earth really hasn't changed a whole lot since they were done. ;)Have you considered the USGS tiles from the TerraServer as well? This mightMany other on-line tile sources have restrictions that I could not (in

I have a ToDo item to support UI-View-type tagged images as backgroundI have never used UI-View mainly because it was only recently I found a laptop for mobile use. So I don't have any clue what is needed there.
Actually the software is $59.95 for the basic version. It comes with zero maps. If you want GIS or CAD support, then it is only a bit more. Geobuddy for geocaching is also $59.95. Check out ExpertGPS. There is a 30-day trial available. If for no other reason than to run it for comparison. I download just about every mapping package. Except for Xastir, I don't have any real knowledge of Linux yet.I use ExpertGPS (E-GPS) for the majority of my mapping needs. Actually, thisGiven that data size, it sounds like an expensive program to be
You may have seen references to esyGPS on the Tracker2 forum. It is an excellent tool for managing waypoits on a GPS. I used it originally myself for that purpose.
You are right about your intended use. I can except that. Other tiles just might be a reasonable option, again for SAR and such.
I will have to read about this "Slippy" thingie. I have heard about it briefly on another forum.I have grabbed most of the tiles in the area I travel in on a regular basisMy software will use any 256x256 tiles that adhere to the "Slippy Map"
I think the USGS tiles on the Teraserver are different in size (200x200?) and right off hand I couldn't tell you what projection they are in.
I noticed the license and won't be purchasing it mainly for that reason.I also have a collection of scanned maps that provide additionalBe aware that some of the new "universal map downloader" software goes
As for as enabling, if someone wanted to use maps generated from Google or other source, it wouldn't take much effort to make them useful with the software you already have. I understand the OSM tiles and the Google tiles are the same size already and they are referenced to same too. But that is your call and I am good with that. Besides, if OSM has street maps, then the only useful ones for me are the terrain series. I think the topos have them beat.
The scanned maps I am using are those I scan myself and those provided to the boating society for navigating waterways and such. They are labeled 'not for navigational use'. But that is okay because I use then on land to learn about them and to identify offshore points, like lighthouses, rock outcroppings, etc. I hope to get out on a kayak at some point. Scaned maps do require a calibration. E-GPS allows for a 3-point cal. These may or not fit in the ARPS scheme of things.
If a rectangle is drawn on the map, then the retriever will allow the user to grab any and all tiles at any zoom selected. The rectangle can be any size. While the rectangle is useful, another package (USAPhotomaps-TerraFetcher) allows drawing a polygon and grabbing those within it or creating a route and retrieving along the route.The E-GPS tile tool as a rectangular box that one draws on the screen andYes, can you tell me if it covers the entire area at all of the selected
The retrieval tool is really easy to use but I think the Terraserver has some sort of maximum rate or something. After a larger number of tiles have been downloaded, it seems to slow down the serving of tiles. But I have neither timed it or found a way to measure it. So grabbing large amounts is practical for a limited amount for time. Or it might be caused by my PC going into screen save mode. I don't really know. I just don't grab everything for an entire state (I do have all of NH and large portions of ME, MA and VT). I would bet the OSM server might slow down retrieval as well if someone was going for a whole enchilada or two wth rice and beans included. But at least with tile purging off (for /32), that should only be a single downloading event.
I outline 1x1 degree at a time in the topos and will repeat the grab with a smaller set of aerials. I find the aerial to be less interesting. Part of that is because of my interest of taking the 4x4 off the pavement. Aerials are not much use there.
Lately for my trips, I just use my simulator. I find it works just fine. Currently, it takes a bit of work but that is going to change this week. I do a couple of conversions to get the data into a specific format with Excel. The software is changing to do it without any extra effort.
The simulator does require two serial ports at this time. There should be a way to emulate a serial, I haven't explored it yet. In theory, I shouldn't need anything but a virtual port.
APRSIS32 will fetch the current zoom level and theI have a select delay. When I am playing back NMEA data I set it to the rate it was saved at. When I built the NMEA sentence (only RMC at this point) I very the rate to allow for more download time. I usually do this when other things are getting done like eating, sleeping, etc. It has worked quite nicely for APRSISCE/32. When it is in better shape for general use, I would be happy to provide the simulator to those interested.
Rather than mess up an explaination:I have also played with USAPhotoMaps so I have a tile collection for that asUTM Zone? I'm not familiar with that term?
That goes without saying. I am happy to have found your work and am looking forward to its future!Appreciate your work on this software!And I appreciate the considered questions and suggestions, as long as
I jsut hope I don't wear out my welcome with questions and requests! ;)
I am looking forward to my next day to AR. I know have a laptop for mapping and such. With your software, it will be very cool!
