Hi, I want to export a cave line plot as GPX to superimpose over a surface map in mapping programs. A cave line plot consists of (visible) stations, i.e. named...
... Because I would have as many tracks as survey shots (the software does not "know' passages, only single survey shots). Isn't there a limit on these? I...
... surface ... shots, i.e. ... survey ... seems ... Any given program may have some limit. I think you can find a program that would let you have 30,000...
... Actually, I don't target any specific software, I just want to add a GPX export feature to my cave survey freeware. I know a user would use it with...
IMHO for a very high number of points / tracks, a GPX file is not the best solution. Instead you should store them in some sort of data base, and extract in...
... I am not the repository of each user's data and I don't want to force my users into converting the data back into a GPX via a proprietary format. Auriga is...
... There are no limits on the number of points or tracks a GPX file can hold. It's limited only by the ability of your software. I've tested my software on...
... If I use <wpt> for stations, won't I have to duplicate the lat/lon info in the <trk/trkseg> tag? I don't see a way to first declare all my <wpt> (e.g....
... A waypoint is a permanent location, like an airport or a radio navigation aid, or on the ground, an orienteering control. A route is a series of ...
Waypoint - any point that has coordinates (latitude and longitude) and if applicable height. Waypoints can be defined by you or others. Route - A collection...
Other than the usual Windows modified-date and things like that, I don't think you CAN tell. It's just a text file. If you put some sort of checksum at the...
Hello, ... 1. explain why you care about this - you might get a better answer. 2. GPX editors are supposed to fill in the creator="my_program.exe" attribute at...
... You can't tell if someone modified the file under normal circumstances. If you need to be able to tell, you would have to add an encrypted signature. A...
... In the above I'm assuming that you don't have the original GPX file. If you have the original file, just run a difference program on the original file and...
I'm creating a GPX document in .NET, and I am having trouble coding the document (root) element. The document element contains an XSI namespace declaration...
Hello, I wrote an utility to download tracks from a GPS based on the MTK chip (i-Blue 747 data logger). In the data log there are fields that do not accomodate...
... At a glance, very little of this is actually MTK-specific at all; it's closer to "raw" NMEA capture, right? There have been discussions on this list (long...
Hello, ... Yes, please don't call your schema "MTK" - try to create something as generic and reusable as possible. Put the satellite positioning stuff in a...
I am using .NET Frameworks xsd.exe to generate classes for both the 1.1 and 1.0 version of the gpx.xsd. I am not sure how to quickly tell which class I should...
Hi, I'm just starting reading GPX data with PHP. I've played with XML before but I'm not a PHP expert by a long shot. I've been able to dump Garmin Training...
... Those are attributes. How you read them depends on which library you're using, but look for the word 'attribute'. XML or XMLReader ? Or are you reading...
... If you are, you're headed down a bad path. If you don't know what XML attributes are, you don't want to be parsing XML. Use an XML parsing library;...
passing funny brackets? sounds very painful indeed I've put the source I'm using in the files section "garmin_tcx_simple_parser.php" Its adapted from a...
