There are some extra tools within Optioneer that can be useful for analysis.
📐 Measure distance or area tool
By right-clicking anywhere on the map, a menu will appear with three options:
Inspect (view tooltip)
Measure area
Measure distance
By selecting Measure Area, you can draw a polygon on the map by clicking around the perimeter of the area. The area will be provided in a pop-up at the top of the screen. To stop measuring, double-click on your last point.
Similarly, to measure a distance, select Measure Distance from the menu. A node can be added with each click and Optioneer will display the distance of the line in a pop-up at the top of the screen when two nodes have been chosen. To stop measuring, double-click on your last point.
📍Displaying icons
If the Linear Features design rule is active in a configuration, the locations of the crossing will appear as icons in the Map View and in the Vertical Profile. The visibility of these icons can be managed via the Icon Visibility tool on the left-hand side toolbar. This helps you filter the crossing types you wish to view at that moment.
📊 Polygon Analysis
So far, Module 3 describes the features relating to the analysis of a line. Here we explore our polygon analysis tool, which provides metrics on areas.
This tool can be used to analyse corridors, locations for stations, lay down areas or any other area you wish to understand more about. Follow the steps below to carry out a polygon analysis.
Create a polygon
See Module 1.1 for more details on how to create polygons.
Select your polygon
Go to the Data Window and select the Polygon Tab on the right-hand side.
Select Analyse
From the three-dot menu of your selected polygon, select 'Analyse'. N.B. You may need to scroll to the far right of the tile to find it.
Select the data for analysis
A window will pop up. On the right-hand side of the window, you will see the data in the project area. You can choose to view these by dataset or collection. Select the data by clicking on the checkbox next to it. This will add it to the analysis and it will appear in the column on the left-hand side.
For each data layer, Optioneer will provide two metrics.
Overlap [km2]
This provides the area of the data layer that is present within the polygon.
Feature Count
This provides the number of features from that data layer that fully or partially sit within the polygon.
Buffer Polygons
There is the option to add buffers to your polygon. This can be done by typing the size of your buffer (in meters) into the Add Buffers bar below the results. The buffers can be removed by clicking the cross next to the buffer.
Export
In the top right-hand corner of the Polygon Analysis Window, you will see the download icon. Clicking on this will allow you to name your document and download the results as a .csv.
