Please note: this guide has been written in relation to version 2.0 of the spatial portal due to brought into production in 2019. A different version of the portal will allow similar functions with some small differences in the user interface. If you are unable to access a required function, please contact firstname.lastname@example.org.
This option is presented as a quick way of comparing the environments of a few points. Point comparisons simply use mouse clicks on the map of a few points and the result is a display of those points (forming columns in the legend area) across all layers (rows in the legend area).
1. Select Tools | Compare points
2. Zoom and pan to the area of interest, drop a point on the map. Click on Add Point and drop another point. Repeat for any further points.
You can edit points or remove them from the list. Once you have defined your points, then simply click on Compare and the list of layer values will be displayed for each point. Given the limited area of the legend, only 9 or so points can be displayed.
Once the points are displayed, the CSV file can be downloaded for analysis.
A portion of the downloaded CSV file has been sorted for the difference between the first two sites just to demonstrate the type of analysis that can be done.
An alternative is to use Export | Points where environmental data is appended to an existing set of points, which are usually species occurrences, but can also be any set of points that have been imported.
