工程

Projects are the main data containers on QField and QFieldCloud. Users can create any number of projects. Projects must contain a single .qgs/.qgz QGIS file, and may in addition contain any combination of geospatial files -- GeoPackages, Shapefiles, TIFs -- or data files such as photos, PDFs etc. Files cannot be shared between projects, unless localized layers are used.

QFieldCloud projects have a name and an owner. The owner of a project is a QFieldCloud user or an organization. No two projects can use the same pair owner_name and project_name.

Projects can be marked as either public or private. Private projects are accessible only to users added to a project as project collaborators. Public projects are visible to, and can be downloaded by, any QFieldCloud user.

创建工程¶

A project can be created in multiple ways:

via QFieldCloud web interface;
via QFieldSync in QGIS;
via QFieldCloud-SDK;

文件¶

Files are the skeleton on which QFieldCloud projects work. To make a QFieldCloud project alive users need to upload at least a single QGIS project file in the .qgs or .qgz file formats. All geospatial files must be uploaded using the same relative paths as on one's computer. If external SVG or raster symbology is used, users must upload the corresponding files too.

笔记

QFieldCloud不支持存储在地理包 (.gpkg) 文件中的工程 (但用户仍然可以使用地理包文件为其工程存储数据集)。

QGIS文件的典型文件结构如下所示：

project
├── data
│   ├── basemap.tif
│   ├── bees.gpkg
│   └── fields.gpkg
├── symbology
│   ├── icon.svg
│   └── line-pattern.png
├── DCIM
│   ├── bees-20220404121212.jpg
│   ├── bees-20220405040506.jpg
│   └── fields-20220405040607.jpg
├── project.qgs
├── project_attachments.zip
└── project.qml

The files in a QGIS project can be in one of the following groups by their purpose:

QGIS project file - a .qgs or .qgz project file.
QGIS sidecar files - the utility files to the QGIS project file, such as *_attachments.zip or other sidecar files.
Data source files - all your vector and raster data, such as .gpkg, .tif, .mbtiles or other data source files.
Attachments - all your additional project data, such as .jpg, .pdf or other files.
QField plugins - all your QField plugins, usually .qml files.

文件版本¶

QFieldCloud使用文件版本控制修改，这允许用户把任何修改过的文件恢复到以前版本。文件和文件版本可以在工程的文件部分找到。订阅计划允许每个文件使用不同数量的版本。请参阅 QField.cloud 定价页面并了解更多信息。

删除旧文件版本¶

为了确保只保留相关的文件版本，并降低帐户所需的存储量，用户可以删除过时的文件版本。您可以从工程的文件部分手动删除文件版本。

要删除QFieldCloud中的文件版本，请执行以下步骤：

转到工程的 "文件" 部分。
找到要删除其版本的图层。
单击图层名称旁边的三点按钮。
您将看到指定图层的版本列表。
找出要删除的版本，然后单击旁边的红色垃圾桶图标。
当提示时确认删除，如果想删除特定版本之前的所有版本，您可以激活选项 "Also delete n version(s) older than the selected version.".
删除后，将弹出一条成功删除信息，版本列表将仅显示未选择删除的版本。
