When you launch 1Edit, the Projects page is displayed. This page contains a list of existing projects, the ability to create new projects from a file, and provides access to the Worklist to create and upload projects from jobs that have been allocated to you and/or your work group using the 1Spatial Management Suite.
In 1Edit, a project contains a single dataset that holds all vector and raster data. The data in a dataset is stored using a Coordinate Reference System (CRS) that is defined by the user, and will conform to a schema again as defined by the user. You can define these schemas by loading a GML 3.2.1 XSD file or with a pre-defined template.
The list of existing projects is filtered to show recently opened projects by default, with the most recently opened project at the top of the list. To see all projects that exist on your machine, click All. Use Refresh to refresh the list of projects if you have added data after opening the Projects page. To open a project, select it from this page.
As well as clicking on a project to open it, you can perform other tasks on a Project by selecting the tile using the right mouse button, or by swiping the tile (drag down and release.) This opens the app bar to allow you to delete a project, save a project as a template (see Using templates) or save the project as full or change-only GML. You can also access your Worklist from this page. For more information, see Configuring jobs in the worklist.
Use 
to load a GML 3.2.1 data file containing data,
or to load a GML Schema (xsd) file to create a project from which a template
can be created. The Create Project
page is displayed, where you can specify the dataset, an optional GML
dataset file, and enter a name for the project.
To define the Coordinate Reference system, click Select next to Define CRS. The Define Coordinate Reference System page is displayed. Enter the ESPG number, the extents of the CRS, the spatial resolution in meters and the grid tolerance. The extents do not need to be exact, but should roughly cover the expected range of the data. Making the extents roughly accurate will improve performance. Spatial resolution is also a performance tuning parameter and should represent the size of a small feature in the units of the data. Typically, this is set to 1 when the data is defined in metres. Click Ok to return to the Create Project page.
To use a schema file, click Select next to Schema File and select the file. Click Open to return to the Create Project page. Schema files are specified as xsd files that conform to the GML 3.2 standard.
To populate the dataset from a GML file, click Select next to Select Optional GML File and navigate to the GML file you want to import. When loading GML, the project is named after the GML file. Otherwise, specify the project name manually. Click Open to return to the Create Project page.
If you are only loading a schema to create a template, enter a project name and accept your changes.
To finish creating the new project, click Create. The new project is listed in the Projects page.
To save the current project and all changes made since the last time the project is saved, click Save Project in the lower app bar.
When you close the project, your edits are saved automatically. It can be useful to save your work as you go to ensure that your changes are safe (for example, in case of battery failure.)
Saving a project clears the undo history.
To close a project without saving changes, click Discard & Close Project in the lower app bar. Click Close Project to close the project and save any changes.
To delete a project, right-click it in the Projects page and click Delete Project in the lower app bar or on a touchscreen, drag the project down to display the Delete Project icon.
