Gpx Map Editor

skp2osm lets you use OpenStreetMap in SketchUp.

• Gpx Viewer
• Gpx Track Editor

Motivation

• GPX Editor, as its name implies, is a free open source GPX editor that you can use to view GPX files. It is a portable GPX file viewer that you can use on the go. You can also view NMEA, KML, NGT, and LOG files in it. It provides all tools sufficient to view and analyze GPS data contained in GPX files.
• GPX MAP EDITORS GPX editing tools allow you to research, plan, upload, and export GPX waypoints, tracks and routes. These tools are great resources for planning your next adventure from the comfort of your own home. Export your GPX files to MicroSD, insert/import files into Voyager Pro.

Create 2D outline of a building using 1-2 photos. This is to be a useful tool for areas where high resolution satellite imagery is not available.

Main features

Welcome to GPX Editor. Welcome to GPXEditor. Right click on the map for the general options. Right click on a track for the options for that track. Please consider subscribing, for advanced features. Email admin@gpxeditor.co.uk with any queries. Allowwriteapi (modify the map) allowreadgpx (read private GPS traces) allowwritegpx (upload GPS traces) allowwritenotes (modify notes) Changesets. To make it easier to identify related changes the concept of changesets is introduced. Every modification of the standard OSM elements has to reference an open changeset. The collected data can be displayed as a background of thin lines or little dots within the map editor. These lines and dots can then be used to help you add map features (such as roads and footpaths), similar to tracing from aerial imagery. Global Navigation Satellite System Tracelog.

• Import of OSM files to SketchUp
• Import of GPS tracks in NMEA and GPX formats to SketchUp
• Export from SketchUp to OSM file

Prerequisites

• You should know how to do 3D modelling in SketchUp. You should know how to reconstruct 3D buildings from photos using SketchUp's Photo Matching tool
• The photos used for 2D outline reconstruction should not be cropped!

Installation

Download the plugin from here and unpack to Program FilesGoogleGoogle SketchUp 8Plugins

On mac the folder is: /Library/Application Support/Google SketchUp 8/SketchUp/Plugins

Usage

• Reconstruct 2D outline of a building using Photo Matching tool. The outline should be parallel to XY plane otherwise it will not be exported to OSM file.
• Prepare OSM files and GPS tracks to be imported to SketchUp. Their extent should be quite small.
• File -> Import... to import the files to SketchUp.
• Place the reconstructed 2D outline to an appropriate location inside OSM ways and/or GPS tracks using Tape Measure, Move, Scale and Rotate tools
• Export the 2D outline to OSM file: File -> Export to OpenStreetMap file... The outline will be exported with the tags building=yes and source=skp2osm
• Open the just exported OSM file in JOSM for final editing and sending to the OSM database.

Limitations

• Non-latin characters in the path to imported and exported files are not supported
• Export of grouped objects is not supported. If you group objects in SketchUp, remove grouping before exporting to OpenStreetMap file.

Feedback

Please submit it to the OSM forum. Use the same login and password as at osm.org. There is also Russian forum thread.

Gpx Track Editor

For a variety of reasons, you may want to edit a GPS track log before uploading it to OSM. If you followed the conversion step before now, the track log should be in GPX file format.

Warning:

• You should only upload raw data you collected yourself in the real world.
• OSM is interested in the raw data, so you shouldn't edit your tracks to match what you would like to see mapped. In particular, don't edit the locations of trackpoints, just remove bad ones and split the tracks as required.

Reasons

• To protect your privacy:
  • Your GPS tracks can reveal your exact address and show when you were where. This can give people a lot of information you don't want them to have. You may want to exclude the area around your house (Using filters with GPSBabel shows how to do that with gpsbabel) and possibly modify the timestamps.
• To improve the remove or correct bad data:
  • You may want to remove points where your GPS receiver had poor reception (say you were inside a building).
  • Also, if you spent a while at some place, the resulting cloud of points is not that useful for mapping.
  • If the receiver produced implausible results:
    • distance between trackpoints more than 500 m,
    • speeds higher than 300 km/h lower than 1 km/h (values can be computed by gpsbabel)
• Organization:
  • You may want to split your logs into parts depending on some criteria. For instance, separate the flight log and the bus trip from the airport. This allows more accurate tagging of the uploaded logs.
• To reduce the data volume, you may want to :
  • compress a track to reduce the number of points and speed up uploading.
  • to delete sections of data which have already been uploaded or are not relevant.

Options

• GpsMaster is a free and open source desktop application used to create, view, edit and analyse GPX files
• GPSBabel provides filters (see using filters with GPSBabel). Some of these only work on waypoints, so you may have to convert a track to waypoints and back (gpsbabel allows this).
• JOSM permits reading and writing GPX files. By converting the GPX layer to a data layer, it can be edited, then saved again as a GPX file, or directly uploaded to OSM using EditGpx plugin. Elevation and metadata is preserved since JOSM version 14163.
• Viking, [1], project allows visualizing, editing and uploading tracks to OSM.
• RouteConverter is a platform independent java application that can edit GPX files.
• Check Perl_Scripts#osmtrackfilter and https://svn.openstreetmap.org/applications/utils/filter/ for some command line tools.
• gpsman is very useful if you can see past the unusual tcl/tk user interface.
• GpsPrune allows visualisation (2D, 3D, osm, Google Earth) and editing of GPX files.
• Florb is a really simple map viewer and GPX editor written in C++.
• GPX Editor allows splitting, joining and pruning of tracks, visualises tracks in Google Maps, simplifies tracks using various methods etc. English support forum.
• gpxsplitter splits multi-track GPX files, containing waypoints, into individual one-track GPX files with their respective waypoints. It's useful for GPS units (such as those based on MTK chipsets) that munge tracks and waypoints together.
• gpx_reduce is a small python script that yields high-quality gpx-track reduction/compression.
• Merge Tool and Anonymize Tool are two small console applications (for Windows) to merge gpx files or randomly shift their timestamps.
• Trakclean is a simple Windows console application to eliminate spurious trackpoints (typically recorded when stationary) using a minimum speed or distance criterion.
• TrackProfiler is an online GPS track editor. It allows you to split/merge/move tracks, edit routes, detect and remove GPS errors and add coordinates to images.
• GPS Track Editor is a Windows application to analyze and edit GPS tracks (split/merge/filter).
• GPS TrackMaker (Windows) allows GUI editing of gpx tracks (e.g. deleting parts)
• GPS Utility to manage, manipulate and map your GPS information

• Mercators heaven - GIS.Lab - view, edit or create gpx, kml and kmz on different maps.
• Track Guru Java application for cleaning, merging and splitting of tracks. Can replace elevation values, detect track errors and show overview over large number of tracks.
• gpx.studio is an online open-source tool used to view, create, edit and merge GPX files.
