Tutorial Google Earth Visualise Field Data in and Fusion Tables

Visualise Tutorial Google Earth and Fusion Tables.

Tutorial Google Earth Open Data Kit (ODK) is a suite of tools that allows data collection using mobile devices and data submission to an online server. even without an Internet connection or mobile carrier service at the time of data collection. You can collect data remotely without an Internet connection or mobile carrier access. Gather text, numeric data. media and more with a mobile device. Then. host your data online using Google’s powerful hosting platform. Google AppEngine. and visualise your data as a map using Google Fusion Tables and Earth created by developers at the University of Washington’s Computer Science and Engineering department and members of Change. Open Data Kit is an open-source project available to all. Please visit their ODK project page for more information. recent updates, more tutorials. and to contribute to the project.

Visualise Tutorial Google Earth and Fusion Tables. Earth for this tutorial, we will use the data that’s been previously collected and uploaded to http://odk-tutorial.appspot.com.

This data was collected in the field using Open Data Kit. The data is stored in a Fusion Table and displayed in Google Earth.

Prerequisites

  • No programming skills needed!
  • We strongly recommend that you have taken the prior tutorials, Mobile Data Collection using ODK Collect and Manage Your Data with ODK Aggregate. We also recommend taking Getting Started with Mobile Data Collection.
  • You will need a Google Account to log in to ODK Aggregate and view your data in Fusion Tables (get one here).
    1. Earth On the « List of Forms » page of http://odk-tutorial.appspot.com or your own ODK Aggregate instance. click « Create KML file ».
    2. Earth Several options will appear. For « Field to Map », select the field that corresponds to your form’s GPS location question. For « Title Field ». Select the field that you would like to appear at the top of your Google Earth pop-up balloons. For « Picture Field to Display ». Select the field that corresponds to your photo. Then click « Submit » and your Google Earth KML file will begin downloading. You can do so by using the « Configure Info Window » link at the top of the « Map » view.

    3. Once the file has finished downloading, double click the file to open it in Earth. You should see placemarks for each data submission. If you click on a placemark to open the pop-up balloon. You should see a table with the data values for that submission.If you are using the Sample.xml form, here’s how your pop-up balloons will appear:tutorials_odk_visualize7_google_earthtutorials odk visualize google earthIn this exercise, we will use a sample form to demonstrate the most common kinds of data you can collect with Open Data Kit and and display with Google Fusion Tables and Google Earth. You can get the sample form on your mobile device by following the instructions in the previous tutorial, Manage Your Data with ODK Aggregate.

      Let’s Get Started!

      In the previous tutorials. you learned how to send your form submissions to our instance, or your own instance. of ODK Aggregate. To see the data you added to the form, go to http://odk-tutorial.appspot.com and log in using your Google Account.                                                                                                                          You can choose either Google Spreadsheets or Google Fusion Tables.

      Earth for this tutorial, we will use the data that’s been previously collected and uploaded to http://odk-tutorial.appspot.com. The dataset will continuously be added to as more people take this tutorial and add more data. If you upload data to this server. please note that the server has been made public so please don’t upload material you don’t want others to view. If you collected data using your own AppEngine instance in the last tutorial, feel free to follow along accordingly.

      View Your Data with Google Fusion Tables

      Earth ODK Aggregate provides an automatic link to a table that you’ve created with Google Fusion Tables. Fusion Tables allows you to upload different datasets. merge your datasets. visualise your dataset quickly and easily on a map and query your data. You can also collaborate with others on your data and set different permission levels for different users. The mapping functionality of Fusion Tables is covered in more depth in three other tutorials: Map sample data with Fusion Mapper,Map your own data with Fusion Mapper and Sharing a map from Fusion Mapper.

      1. Earth

        First, you’ll need to publish your data from ODK Aggregate to Google Fusion Tables. In the « Submissions » tab. under « Filter Submissions », select the form you wish to export. Then, hit the « Publish » button.

      2. Earth

        Select the service to which you want to create the connection. You can choose from Google Spreadsheets  an online.
