What’s New in Version 3.3¶
Following customers’ requests, these are the main new features of the latest Pathfinder release:
As we have seen, a new extended Add Scenario dialog lets users access shared scenarios.
Alternatively, they can still create a new scenario based on the one currently selected, adding an optional scenario description:
The last tab in this dialog is similar, but it creates the new scenario by importing its parameters and settings from a previously exported scenario file.
Viewer User Role¶
A new user role has been added to the list of user profiles available in Pathfinder and assigned by a company administrator.
A viewer user can:
However, a viewer-type user can not create or modify any project or scenario. These options will be disabled, or it will be impossible to save the changes.
When a viewer user opens a project, the Add Scenario dialog will pop up automatically to select available shared scenarios for the project. Otherwise, the viewer user won’t be able to see any project data or results.
Path Editing on Map¶
Sometimes, path editing is easier to perform in 2D than in 3D. For this reason, the Information and Editing pylon tools are now available in the Map view as well as in the 3D view.
As in 3D, when the Move tool is activated, yellow circles will be displayed around the points defining the visible paths. To change the location of a point, just click on it and drag it to a different location.
To finish editing, click with the right mouse button and accept the changes. The path statistics will be recalculated.
Future versions will include the ability to add or remove points in the path.
Project Information Dialog¶
In the 3.3 version, a project description can be added when the project is created.
This description and other internal project information can be accessed from the Project menu:
The new Project Information dialog shows the description on the right side, as well as:
The project’s owner: the user who created the project (it can also be assigned by a company admininistrator).
The project’s creation date
The number of layers and scenarios used by the project. Its layers are the same for all users, but the scenarios may vary.
Raster width, height, resolution and area. These parameters give information about the extent, size and scale of the project. The larger the raster width and height of the project, the longer its layers and results will take to process.
Internal coordinate system name and ID. All data in Pathfinder is internally projected to a UTM coordinate system. Its UTM zone and EPSG ID are provided here. When the path results are exported, a copy is saved in this coordinate system.
Scenario descriptions can also be added when creating them. For now, these descriptions are available from Pathfinder’s administration tool. A scenario information dialog will be available soon.
Results Panel Enhancements¶
As users create more scenarios, generate more results and use more cost models, we added some options to improve the presentation of information in the Results panel.
Instead of showing the Resistance Maps, Corridor and Paths stacked on top of each other, users can now split them in separate tabs by using the corresponding option in the View menu:
In this mode, each tab will show only one type of result, leaving room to view and manage more items.
Path Indicator Display¶
A number of important indicators can be available for each path. In previous versions, only the basic cost was shown in the Results panel next to each path. Now the user can pick which indicator will be displayed, the path distance or one of the cost model results.
More Information At Hand¶
Other improvements developed for Pathfinder 3.3 provide users with useful information to make their workflows easier.
The My Datasets tab in the user profile now shows additional information about each company dataset:
Which projects use this dataset? (So, if the dataset is not used any more, it can be deleted).
What is the upload date of the data? (If the data is old, it may require a new update).
What is the number of features in the dataset? (For vector data)
Estimating the duration of a process in Pathfinder is nearly impossible because of the many factors involved, including how many other processes there are, but now the Process Log shows the time it’s taking for each process to complete, so the users have an approximate estimation of how long it will take to run it again in similar conditions.
The Identify tool can be used to find the resistance values at a selected point in the Map or 3D views.
Now it also reports the latitude and longitude of the selected point.
Ring width information¶
For feature data, the size of layer rings (buffers) is defined for all the users in the Layer Preprocessing panel, but the resistances of each ring are defined in the Layer Resistances panel and the layer’s side panel, for each scenario.
In the 3.3 version, the Layer Resistances panel and the layer’s side panel show a tip with the width or size associated to each ring, so we remember them as we define its resistance values.
