In any case, I already had 398,000 GPS points to begin with. This is when a tool like KNIME helps you tremendously to blend data from different sources. Leave a comment and give me the opportunity to learn :-).ĭuring this ETL process, I noticed that some files were missing or even data within some of those files. I am sure that more advanced KNIME users will find a better way of doing this. Here is the detail of the GPX parser workflow that I implemented with KNIME. I chose GPX because I found it easier to extract the data to an intermediate JSON file.Īfter downloading each of the 1,015 individual files corresponding to all the stages of all the variants of all the Caminos, I unified them into a single database of GPS points using the open source, no-code tool for data science par excellence: KNIME Analytics Platform. Data is available in both GPX and KML formats. This information has been provided by the Federación Española de Asociaciones de Amigos del Camino de Santiago ( FEAACS). I am more interested in the technical viability than the perfection of the result.Īs I said before, the starting data is all the GPX files available on the CNIG portal ( Spanish National Center of Geographic Information). I am not an expert programmer and it is a personal project.

  • Use no-code tools and share it in a way that anyone could replicate and improve it.
  • This is one of the most interesting features for pilgrims who have to carry a backpack. I was almost certain that the files would have some elevation inconsistency.
  • Provide extra added value to GPS positions.
  • Using public information from the CNIG about all available routes of the Camino de Santiago in the Iberian Peninsula, visualize them embedded in an article of my web page.
  • In this case, the challenge, based on the previous premise, was as follows:

    Objective: flying over the peaks of the Pyrenees along the first stages of the Camino de Santiago through Aragon. Or just looking at it in a different way. Combining engineering and the Camino gives me the chance to help my fellow pilgrims by showing them data that would otherwise be difficult to obtain. ChallengeĪs you may know, I have a special interest in the Camino de Santiago. The initial premise is simple: geolocalized information available to be processed with no-code tools, and an easy way to visualize it that can be integrated into a WordPress-based website.

    But how to approach the whole process without programming? There is more and more geopositioned information, and being able to visualize it quickly and easily while having it embedded in a web page is the best way to analyze it. Or is it easier to obtain data of this type? I have no idea.Īnyway, lately I have been exploring how to create a 3D map to visualize information from routes in GPX format. What could be the reason? Maybe my natural predisposition to travel and explore. If you have read my previous article, you know that I love visualizing and working with geolocated data.

    Using no code tools to process massive geoloc data replace ( ".000", "Z" ) global_availability = global_starttime + "/" + global_stoptime # Create packet with global variables global_element = czml_output. replace ( ".000", "Z" ) global_stoptime = str ( max ( df_input )). This notebook will walk through the following steps:ĭef point_with_trailing_path ( df_input, time_multiplier = 1000 ): # Store output in array czml_output = # Define global variables global_id = "document" global_name = "Visualizing GPX Data from Strava" global_version = "1.0" global_author = "Will Geary" global_starttime = str ( min ( df_input )).

    If it has four or more elements, they are time-tagged samples arranged as, where Time is an ISO 8601 date and time string or seconds since epoch.įor example, the following array specifies the of an entity at 0 seconds since epoch, 1 second since epoch and 2 seconds since epoch: If the array has three elements, the value is constant.

    In particular, it proposes the following format for describing three-dimensional positions that change over time:ĬartographicValue: A geodetic, WGS84 position specified as. The relationship between Cesium and CZML is similar to the relationship between Google Earth and KML.ĬZML is an attractive paradigm for descriping spatio-temporal data. It describes lines, points, polygons, models, and other graphical primitives, and specifies how they change with time. Cesium defines a JSON data format called CZML for describing a time-dynamic graphical scenes, primarily for display in a web browser running Cesium.
