At this stage, you should see an image similar to the one below: Repeat the same process for Notes and Photos columns, but make sure to change the Type for those columns to Text. For this form, we want to create the following columns to store data: Date, Notes, PhotoД¬lick on Add to Field lists to add your column. We can now create the column headers for our table under New Field section. Under Filter section on the top of the window, type: 3857 and under Predefined Coordinate Reference Systems, select WGS 84 / Pseudo-Mercator EPSG:3857. A new window will appear:ДЇor Database click on вЂ¦ and select the data collection folder on your Desktop and then type survey-db.gpkg for the name of your database.ДЇor Coordinate Reference System (CRS), click on the icon to the right of EPSG:4326 - WGS84. Note that Geopackage is a file based database where you can store multiple tables (spatial or non-spatial). To create a survey layer, in QGIS, from the main menu select Layer > Create Layer > New Geopackage Layer вЂ¦. Save your project as pothole survey in the data collection folder. From the Browser panel (usually located on the top left side), expand XYZ Tiles and double-click on OpenStreetMap to add it to QGIS: To simplify things, we can create a folder on Desktop (referred to in this tutorial as data collection folder) and store everything there. LetвЂ™s start by opening QGIS and add the above layers to our project. The GIS format best suited to store spatial information, is Geopackage. Also, it would be good to attach some notes for each pothole, take a photo of it and add a date for survey. In this case, we want to survey potholes. point of interest, tracks or parcel of land). For survey table, we need to decide on a form structure and the type of feature you want to survey (e.g. In addition, you need to set up a table (or layer), to store your survey information.ДЇor background data, we are going to use Open Street Map. Usually, you will need some data for your background layer (so that you can locate yourself!). To be able to survey data, we need to set up a project in QGIS. Note that after signing up to the Mergin service, you have to activate the account by clicking on the link sent to your email. The Mergin service allows you to transfer data between your PC/laptop and mobile/table via the cloud. In addition, you will need to register with the Mergin service. Input app - for your mobile table: you can download the app from Google Play Store or AppleвЂ™s App Store.
