About datasets
Datasets are Neara data structures optimized for a variety of scenarios. They are uploaded or created in projects, and may be temporary or permanent.
Common Neara datasets include:
Point cloud, based on imported LiDAR data, or generated as the output of a classification process
Geo Data, for example based on imported GIS data
Your Network Model
Analytics reports
Imagery, such as satellite and aerial imagery
You will typically create, process, and manage datasets inside a project. However, datasets are "global". This means they exist outside of projects, and more than one project can reference the same dataset.
Explore all datasets in your organization
The datasets displayed will vary according to those configured and available in your organization.
On the Home screen, expand the Datasets menu:
Select a dataset category under that menu item to see available datasets in that category, below a map representation of the location of those datasets (in this case, Point Cloud datasets):
Depending on the dataset category, you can also click Show in a dataset row in the table to zoom directly on the map to the location of that dataset:
Managing a project's Datasets
In a project, click the Datasets tool on the toolbar to manage the datasets used in that project:
Add a dataset to a project
Click the Datasets tool on the toolbar, and then click the Add Dataset option in the properties panel in the sidebar:
The popup shows a list of datasets available to you by organization. Click the Show link on a dataset to view on a map:
You can increase or decrease the size of that area with the Import Radius option:
Clicking into the area on the map will display a list of the datasets available, ready for you to select specific datasets to load into your model:
Usage notes
If you choose to import Network Model data we recommend that you also import Point Cloud data at the same time to ensure that the ground level is set correctly
Importing two different Point Cloud Datasets in your model is supported - however if the any of the Point Cloud Datasets contain data with different EPSG codes Neara will display an error message because it cannot determine which EPSG code to use for the model
If you import Network Model data, a new model will be created based on the design template that was used to create the Dataset: ensure that you have saved your current model to avoid losing changes
If you importing only Point Cloud data, the Point Cloud dataset will be imported in to the model that you have open. Once it is in your model, you will be able to manage the data as described below.
Loading dataset data into the project
For performance reasons, a dataset's data is not all automatically loaded into the Perspective view.
Once a dataset has been selected for use in your project, you can increase the area of data loaded and displayed for that dataset by moving your mouse over the Perspective view and clicking.
The area of data that will be imported is highlighted in the perspective view as a blue hatched area:
You can increase or decrease the size of the imported area by updating the import radius within the Dataset tool Properties panel in the sidebar:
For Point Cloud datasets
Once imported, control the density and display of Point Cloud data using the sliders under the Dataset configuration section of the Properties panel in the sidebar:
Remove a dataset from a project
To remove a dataset from a project, click the (x) next to the dataset's name under the Dataset configuration section of the Properties panel in the sidebar:
This will not automatically remove a dataset from your organization account
Requesting a dataset from another organization
Importing a dataset from another organization works in the same way as importing a dataset into a project from your own organization.
However you first must request access to the data from the organization that owns it.
Select the Add dataset option in the Dataset tool Properties panel in the sidebar, and select the name of the organization on the popup.
If the owner organization requires external users that request their data to undergo further authentication, it will happen at this point - a new tab will pop-up in your browser (ensure that you allow popups if prompted) where you will be asked to log in to an identity provider, e.g. Okta. After you complete this authentication you will be allowed to proceed.
The Map view in the popup will display all data that this organization owns, as well as any regions that you have previously requested from this organization.
Previously created access requests are shown on the map:
Green: Approved regions
Yellow: Regions that require approval from the owner
Red: Regions that were rejected by the owner
Clicking on the map will attempt to load dataset data in the same way as loading data from your own organization.
Requesting access to non-approved regions
If the region you attempt to load does not contain an approved area, you will see a No access error. To access that region of the map, create a new Access region by clicking the Request new area option under the Rejected areas section of the popup.
Neara will then allow you to draw a polygon on the map: outline the area you would like to request access to. Once the polygon you are drawing is closed, you will be able to create additional polygons for the same request, or submit the request. Before submitting a request you will be able to write a message for the approver.
Depending on the preferences set by the organization, your access request may be immediately approved, in which case the polygon will turn green. If manual approval is required, the polygon will turn yellow.
Selecting access region requests from the Dataset tool highlights them in the map and allows you to delete these regions. Deleting an access region removes that region from the approval queue of the organization.
