# Opening Surveyed Data on Your Computer

In the last tutorial you learnt how to capture field data using Mergin Maps Input.

In this tutorial you'll learn how to transfer data from mobile device to computer in seconds using QGIS, a free and open source desktop GIS package. Mergin Maps Input is based on QGIS, which means it's able to visualise and edit data in the same way QGIS can. This offers us great flexibility which we'll start to see in a moment.

# Before we start

Please ensure you have already:

# Putting your project in the cloud

  1. Press the Upload button

    You may now be asked to log in to Mergin Maps or create a new account. If you're already logged in, skip to step 4.

  2. Log in to Mergin Maps

    How to Sign Up to Mergin Maps describes several methods of registering.

  3. Now that you are logged in to Mergin Maps, pressing the Upload button should start sending your project up to the cloud. Initiate the upload once again:

  4. Wait for the project upload to complete.

Now that your project is in the cloud, it can easily be shared with colleagues or downloaded to your computer.

# Locating and opening your project

  1. Open QGIS on your computer

  2. Install the Mergin Maps plugin for QGIS.
    You will use your Mergin Maps credentials to configure the Mergin Maps plugin for QGIS.

  3. Find the Mergin entry in the QGIS Browser panel:

    TIP

    If you cannot see the Browser panel in QGIS, ensure it's enabled under View (top-level menu) > Toolbars.

  4. Expand the Mergin entry and find your project under My projects

  5. Right-click on the project and select Download

  6. Select a folder under which your project will be stored locally.

    For example, create a folder called Mergin Projects under My Documents or select this folder if it already exists.

    The Mergin Maps plugin for QGIS will automatically create a subfolder based on the project's name.

    The project will now be downloaded.

  7. Open the project when prompted:

    Your survey project is now open in QGIS:

# Extracting data from QGIS

Users who are not already familiar with GIS may be wondering how they can extract their data into familiar tools like MS Office and how to access their photographs.

There are so many ways you could extract the data but here we'll just cover the basics.

  1. Locate the Survey layer in the Layers panel:

  2. Right-click n the Survey layer and select Save Features As...:

  3. Export the features

    • Set Format to Comma Separated Value [CSV]
    • Specify an output file name
    • Uncheck Add saved file to map
    • Click OK

    You should be able to open the resulting file in Excel.

  4. Locate the photos

    The photos can be found under the project folder. Assuming you followed the suggestions above, these should be located somewhere under Documents\Mergin Projects:

If you're new to QGIS we really recommend getting some basic familiarity with the software. QGIS is a powerful tool with a great community that can help you achieve a lot.

TIP

QGIS Documentation QGIS User Guide (opens new window) and QGIS Documentation QGIS Training Manual (opens new window) are great resources to get familiar with QGIS and its functionality.

# Identify features tool

You can also use QGIS to view the data you surveyed in the field.

  1. Select the Survey layer in the Layers panel

  2. Select the Identify Features tool:

  3. Click on your survey point. The feature's attributes should be shown:

# Summary

In this tutorial you learnt how to view a survey project you created on your mobile device on your desktop computer.

You also learnt how to export captured data for use in spreadsheets and how to access photos you captured in the field.
