There are some extra tools within Optioneer we often adopt during the analysis stage.
📐 Measure distance or area tool
By right-clicking anywhere on the map, a menu will appear with three options: Inspect (view tooltip), measure area and measure distance. If 'Measure Area' is selected, 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 selecting double click on your last point.
Similarly, to measure a distance, select 'Measure Distance' from the menu. Select a minimum of two points and Optioneer will display the distance of the line in a pop-up at the top of the screen. To stop selecting double click on your last point.
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 Route Icon Selection tool on the left-hand side toolbar. This helps you filter the crossing types you wish to analyse at that moment.
📊 Polygon Analysis
So far, Module 3 describes the features relating to the analysis of a line. This module explores 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.
From the three-dot menu, select Analyse.
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.
This provides the area of the data layer that is present within the polygon.
This provides the number of features from that data layer that fully or partially sit within the polygon.
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.
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.
