As a 32bit program, GPX Editor can't use more than 4Go of ram, but it was able to add the valid gpxes on my computer just fine (with "only" 4Gb of ram). Having somthing doesn't mean it's put to good use ;)
I know some of the files are corrupt and i didn't even say that they worked for me to add, thats not the problem at all because they can't be added. The problem is that there is some problem with "waypoints", i doesn't even want to have any waypoints in my gpx, but i can't sit here and delete 800 waypoints one by one, because theres no way to delete them all at the same time either. |

Strange, here I have no problem at all dealing with waypoints.
I can add the ability to delete them in one click if it really bothers you. |

Just an option to delete ALL waypoints at the same time would be nice |

I added this possibility in this beta :
GPX_Editor 1.3.45 Beta.
Just select the Waypoint List at the root of the GPX and click delete. |

do you think there could be a way to merge track segments too?
the waypoint delete function helped me a lot on the way, got a bit longer with merging gpx files, but now i have 1 track and 2995 track segments and every segment with a LOT of points, and now again getting the memory problem. |

| There's already a command for that. Right-click on the track, first sort them by date, then merge them. |

version 1.3.46
- Ability to delete metadata, extension and waypoints in one click.
- Ability to ignore XMl version (GPX was designed with 1.0 version).
- Ability to keep line feeds (not advised as I couldn't test it thoroughly) |

Have you ever thought about doing a x64 version?
Or make it less memory-intensive?
I can't use it to what i really want to because of the memory, maybe i need to look for another program for that, but i really like GPX Editor, and would be very nice if the memory stuff was improved. Now when merging tracks and segments, a lot of them, it won't work because of the memory. |

64 bit Delphi doesn't exist yet, and even if it's released, I doubt it will be 0$, which is how much I can spend to develop GPX Editor.
As I said earlier, maybe GPX Edito is not the right tool for this job. |

| well i think it's a good program, and a good tool for me, but would be so much better tool if the memory stuff was improved.. :) |

It's great! Your tool is exactly the one, what I'm looking for during several days. Well-known and quite handy GPS TrackMaker cuts out track fields, which are so necessary for track mathematic processing and smoothing -- your application keeps a part of them, besides you seem to accept feature requests. :)
I think the following information would be useful for many here. I'm writing this in details to explain and substantiate desiring feature request to GPX Editor.
I've found quite useful tool, NMEA Processor, which performs several track processing procedures, namely:
- HDOP filtering,
- Remove drifts
- Speed smoothing
- Track generalization
- Track smoothing using a) Kalman filter, b) double exponential algorithm, c) weighted spline curves.
The tool has English interface and quite intuitive. Unfortunately, the product site and the Help are written in Russian. Details about used algorithms was taken from these sources:
Rosen Ivanov "On-Line GPS Track Optimization Algorithm for Mobile Platforms"
Joseph J. LaViola "Double Exponential Smoothing: An Alternative to Kalman Filter-based Predictive Tracking".
NMEA Processor can be downloaded here: http://depositfiles.com/files/v2hryd1ij (the home page of the tool keeps actual link to the latest version)
This application recommends to write tracks with the following number of extra fields to achieve more accurate result:
GPX Editor could be used as a great tool for preprocessing for further final track smoothing. It would be great if GPX Editor could safe all fields, which are used for track smoothing. Es ce que c'est possible? |

Very interesting indeed. The previous attempt to filter data didn't really succeed in my opinion. You can already filter by HDOP, speed, elevation and number of satellites in GPX Editor, which are quite reliable methods to delete bad datas.
GPX Will save any data which are part of the GPX framework, no more, no less.
I'll look into those method as soon as I'm back home (in a few weeks).
Thank you for your feedback ideas and links ! |

Je suis content que mes information a été utile.
Dans le système d'aide (Help) on se dit de Smoothing Spline algorithme avec les détails. Je peux traduire pour vous cette description (de weight ratio) et la page de bibliothèque "Tracing of 1-D smoothing cube spline" http://www.srcc.msu.su/num_anal/lib_na/cat/i_htm_c/is01r_c.htm, qui a été utilisé dans la programme. |

Just a suggestion for some more tools to make life easier (all numbers are only for example):
- Split track by time: if time difference between 2 points is greater than "5 min" - split it here
- Split track by speed: if speed during "5 min" is less than "1 km/h" - remove them and split track
These would be quite useful for working with a NMEA track from a GPS datalogger, for example.
Also, quite often the program closes silently when trying to change "Multiplier" in Filter | Point reduction |
