I'll move this to the top of my to-do list and have another attempt at implementing this in ExifTool. Check back in a couple of weeks. That's fantastic news. I appreciate that. I'm making real headway here, but unfortunately have no solution yet. So if you could send me a small sample video containing GPS information I will try to extract it for your particular camera model.
Upload a raw MP4 to a file sharing service and email me the link philharvey66 at gmail. I was looking around the net for info a few days ago and it seems that the places gps info gets stored varies wildly. For example, this script indicates that some GoPros save it in a separate stream. Another site can't re-locate says that another camera saved it in the subtitle stream, so you could see them just by turning a videos subtitles on. But it's awesome that you're making some progress at least.
Hi StarGeek, Yes, exactly. I am fairly confident I can extract this metadata from these various locations, but each will take some time, and I need sample videos of each and it would help if I had approximate GPS coordinates to make sure I'm extracting these properly. I did find one sample that stored telemetry in a text track, and am extracting that now.
Lets see if they could share this knowledge. I actually must have hit that link at some point, as it shows up as an already viewed link. I just didn't keep track of it.The vast majority of us carry a little GPS device in our pockets all day long, quietly recording our location. But location is more than just latitude and longitude; it can tell us about our speed, our direction, our activities, and frankly our lives.
Some people regard this as terrifying, but I see a wonderful dataset. Initially, I didn't have much of a drive to fiddle with my own location history. What could I really do that Google Latitude couldn't already? But after Latitude's demise inI entered full fiddle-around mode, and quickly discovered the incredible array of tools that Python puts at your disposal to easily and beautifully manipulate geospatial data. This blog post focuses on how to analyze your location history data and produce some cool maps to visualize how you spend your time.
Of course, there are 1, more ways to utilize location history, but hopefully this post gives you the tools to pursue those other ideas. If you're not interested in the learning the code to make these graphs but know me personally, stick around. You might even learn a thing or two about me.
And of course, all this code will be executed using IPythonmy best friend. Here's my import list for this tutorial.
If you've previously enabled Google location reporting on your smartphone, your GPS data will be periodically uploaded to Google's servers. That's plenty of data to work with. Google provides a service called Takeout that allows us to export any personal Google data. How kind! We'll use Takeout to download our raw location history as a one-time snapshot. Since Latitude was retired, no API exists to access location history in real-time.
Pandas is an incredibly powerful tool that simplifies working with complex datatypes and performing statistical analysis in the style of R. Because of its flexible structure, I find myself spending a fraction of the time coding the same solution as compared to pure Python. We won't be going too in depth. So, you've installed Pandas. Let's get started! We'll read in the LocationHistory. Now you've got a Pandas DataFrame called ld containing all your location history and related info.
We've got latitudelongitudeand a timestamp obviouslybut also accuracy, activitys [sic], altitude, heading. Google is clearly trying to do some complex backend analysis of your location history to infer what you're up to and where you're going and you'll see some of these fields in use if you use Google Now on your smartphone. But all we'll need is latitude, longitude, and time.
The more I learn about mapping, the more I realize how complex it is. But to do what we want to do with our location history, we're going to have to become experts in mapping in a couple hours. We don't have time to learn proprietary GIS software or write our own methods to analyze map data.We are still shipping! When you place an order, we will ship as quickly as possible.

Chat With Us. Skill Level: Advanced. In my quest to design a radio tracking system for my next HABI found it very easy to create applications on my computer and interact with embedded hardware over a serial port using the Python programming language.
My goal was to have my HAB transmit GPS data as well as other sensor data over RF, to a base station, and graphically display position and altitude on a map. My base station is a radio receiver connected to my laptop over a serial to USB connection. However, in this tutorial, instead of using radios, we will use a GPS tethered to your computer over USB, as a proof of concept.
Of course, with an internet connection, I could easily load my waypoints into many different online tools to view my position on a map, but I didn't want to rely on internet coverage.
I wanted the position of the balloon plotted on my own map, so that I could actively track, without the need for internet or paper maps. The program can also be used as a general purpose NMEA parser, that will plot positions on a map of your choice. Just enter your NMEA data into a text file and the program will do the rest. This tutorial will start with a general introduction to Python and Python programming.
Once you can run a simple Python script, we move to an example that shows you how to perform a serial loop back test, by creating a stripped down serial terminal program. The loopback test demonstrates how to send and receive serial data through Python, which is the first step to interacting with all kinds of embedded hardware over the serial port.
We will finish with a real-world example that takes GPS data over the serial port and plots position overlaid on a scaled map of your choice. If you want to follow along with everything in this tutorial, there are a few pieces of hardware you will need. If you are already familiar with installing and running Python, feel free to skip ahead.
Python is an interpreted programming language, which is slightly different than something like Arduino or programming in C.
Precise Point Positioning (PPP) HOWTO
The program you write isn't compiled as a whole, into machine code, rather each line of the program is sequentially fed into something called a Python interpreter. Once you get the Python interpreter installed, you can write scripts using any text editor. Your program is run by simply calling your Python script and, line by line, your code is fed into the interpreter.
If your code has a mistake, the interpreter will stop at that line and give you an error code, along with the line number of the error. At the time of this tutorial, Python 2. Python 3 is available, but I suggest sticking with 2. After you install Python, you should be able to open a command prompt within any directory and type 'python'.
You should see the interpreter fire up. If you don't see this, it is time to start some detective work. Copy your error code, enter it into your search engine along with the name 'python' and your OS name, and then you should see a wealth of solutions to issues similar, if not exact, to yours.Downloads map data from a number of websites, including openstreetmap.

To run or build on Windows you will need to install the following; Python 2. You may download any of the following archives 1.Released: Jan 16, View statistics for this project via Libraries.
This is a simple Python library for parsing and manipulating GPX files. You can see it in action on my online GPS track editor and organizer. There is also a Golang port of gpxpy: gpxgo. See also srtm. Note that the generated file will always be a valid XML document, but it may not be strictly speaking a valid GPX document.
For example, if you set gpx. And the file won't be valid. Most applications will ignore such errors, but Be aware of this! That's because the library object model works with both GPX 1. For example, GPX 1. If you parse GPX 1. But if you have a GPX 1. If you want to force using 1. Another possibility is to use extensions to save the speed in GPX 1. Extensions are part of GPX 1. If lxml is available, then it will be used for XML parsing. Otherwise minidom is used. Note that lxml is times faster so, if you can choose -- use it :.
The GPX version is automatically determined when parsing by reading the version attribute in the gpx node. If this attribute is not present then the version is assumed to be 1. A specific version can be forced by setting the version parameter in the parse function. Possible values for the 'version' parameter are 1. Before sending a pull request -- check that all tests are OK. Run all the static typing checks and unit tests with:. Gpxpy runs only with python 3. The code must have type hints and must pass all the mypy checks.
The repository contains a little command line utility to extract basic statistics from a file.
Example usage:.Calibre has the ability to view, convert, edit, and catalog e-books of almost any e-book format. Load, modify and save your GPX 1. Add and remove waypoints, edit track and routes, simplify tracks reducing file's sizeclean recorded data, add and edit GPX metadata, edit waypoint, route and track properties, all with real-time preview.
You can import, plot and create tracks, routes and waypoints, show OSM, Bing Aerial and other maps, geotag images, see real-time GPS position not in Windowsmake maps using Mapnik not in Windowscontrol items, etc. Program for downloading web source maps or local files maps for various programs or GPS devices. An abritary number of tracks may be opened or created, tracks may be merged. A track may be splitted, reversed or edited e. Points may be inserted or appended to a track routing supported or may be moved or deleted from a track.
Maps of several providers are available, the default map is OpenStreetMap. Currently supported track formats: garmin route, gpx and txc, kml, import from www. To run the software, a java runtime installation is required may be obtained from www. Main feature is a live preview to directly see how the selected formatting option affects the source code. Open source server for GPS trackers. Application includes embedded web server to track devices on map.
GG-Tracker tracks the location of your mobile device.
GG-Tracker can run standalone or integrated on an existing webpage. The application is built using the template framework Bootstrap which makes it fully responsive fits on any screen.
This project hosts various plugins for the OpenCPN chart plotter, which are not bundled with the core package. OpenCPN is a free software GPLv2 project to create a concise chart plotter and navigation software, for use underway or as a planning tool.
OpenCPN is developed by a team of active sailors using real world conditions for program testing and refinement.
All softwares from back-end to client are open-source under AGPL v3 license. ODTBX functions and utilities are combined in a flexible architecture that allows for modular development of navigation algorithms and simulations.This document assumes you are using gpsd version 3.
Using other versions will fail in strange ways. The rare few that have a GPS that output raw measurement data for L1 and L2 can achieve absolute accuracy of around 3 cm.
The lucky owners of an L1 GPS that outputs raw measurements can get about 0. The majority will only be able to get somewhat better than 1.
Patience is required. For best results 6 to 24 hours of data is required. Post processing time may double that. This document is not about getting high precision dynamic positions from your GPS. RTK users will still want to read this document. This document assumes that you have installed gpsd version 3. Before continuing you should know how to start and stop gpsdand how to use cgps to see you current position and fix status.
This will allow Simple Averaging. You will also need Python and gnuplot installed. The Python and gnuplot do not need to be installed on the host that is connected to the GPS, they are merely needed for post processing. For basic PPP 0. The end goal of this process is to determine the latitude, longitude and altitude of your GPS antenna as precisely as possible. Ever noticed how two "accurate" GPS placed side by side can give wildly different latitude, longitude, and especially altitude for the same spot?
After an ECEF position is calculated, it is converted into latitude and longitude using a datum. So many to choose from. NAD83 is pinned to the North American tectonic plate. Since then the tectonic plates have moved. In the two datums can differ by more than 2 meters in the continental USA. It is common when using NAD83 to also specify the year epoch of the measurements.
This allows archival, and current, data to be used to similar accuracy.Location using Python
It gets worse.
