QField Feature

QField: The Field Collection App for QGIS

QField is an open-source solution for mobile data collection for Android, iOS, and macOS. It’s built by the QGIS team, which we rank as the second most popular GIS software today.

Although it’s relatively new compared to other field apps, it’s still rich in features and free to use. Here are some of the highlights of QField:

  • Works fully when offline with customized forms
  • Supports various formats and wide symbology
  • GPS positioning and camera integration

Today, let’s go through the basic steps in order for you to build customized forms and take your QGIS projects for field collection usage.

How To Use QField

QField Mobile

If you’re already familiar with QGIS, then you’ll be quick at familiarizing yourself with QField. This is because most of the setup will be in QGIS Desktop.

Basically, you start with a QGIS project. Then, you customize the layers you want. Finally, build a QField package for field usage and sync your data back in the office.

Currently, QField is available for Android, iOS, and macOS.

But let’s get a bit more detail on how to use QField. Follow the steps to get your QGIS project in working order to get it ready for the field.

Step 1. Download the QField Sync plugin

The QField Sync plugin analyzes your project and suggests any actions to make sure the project works with QField. This plugin is well-supported by its developers with over 150,000 downloads already.

The main purpose of this plugin is how you prepare and package a QGIS project so that it’s compatible with QField. It sets up which layers and base maps you want to use in the field.

Step 2. Configure your project

First, you will have to configure your current QGIS project. Before you configure your project, you will have to add any layers that you want to be a part of your field campaign.

Once you’ve added them, you can start to configure and set up your QGIS project. All the configurations will save to your current QGIS project.

Step 3. Layer configuration

The layer configuration will control the layers that will belong to your field work package. Here are the options you have for layer set up:

  • Copy – Copies the layer to the project
  • No action – Only for WMS and WFS
  • Offline editing – A working copy of the data. After synchronizing any changes after data collection, any changes will be transferred to the main database.
  • Remove layer – Layers will not be part of the working copy such as basemaps.

Step 4. Basemap setup

The basemap serves as the underlying layer for your fieldwork. You can set it to your area of interest. You have two options for your basemap.

Layer – This is a great option to generate an offline map of a WMS or raster layer like an ECW.
Map theme – A combination of several layers which can be used as a basemap for fieldwork.

Step 5. Create a QField package

QField syncs with your QGIS project so you can take it out to the field. But before you can take your QGIS project to the field, you have to create a QField package.

In order to package your QGS file, you have to ensure that you’ve completed all the necessary configurations from above. Afterward, you can package it with the QGS file and associated data

Step 6. Start your field work

The QField Mobile App is available for Android, iOS, and macOS.

First, download the Android App from the Google Play store. Next, you will have to upload the QField package to your mobile phone.

When you go out to perform fieldwork, the QField package will contain all of the layer and basemap configurations.

At this moment, the QField mobile data collection field app has a 4.6-star rating.

Step 7. Synchronize from QField

Once you finish data collection in the field, you can copy the data from your phone and overwrite the project. Any updates in the field including photographs will now become part of the project.

QField Cloud

Datasets can be locally stored or accessed remotely. One of the services that you can use for data collection is QField Cloud.

This type of setup allows you to seamlessly work in sync as a team with more efficiency.

Although it’s still in beta, there’s been a lot of progress in development.

Currently, you can manage teams, design highly customizable forms, and work both online and offline.

Conclusion

Field data collection is generally a tedious activity. Without a mobile collection app like QField, you’d likely enter information into a spreadsheet on paper, then digitize it using GIS software.

That’s not something that most people would enjoy doing on a regular basis. But with a program like QField, mobile data collection can be made easier and more efficient in many ways.

This article introduced you to how to make your field data collection more efficient by using tools like the QField Sync plugin.

It has also helped you understand how to configure your layers and base maps as well as create a QField package for any type of fieldwork.
