Description

A feature was recently added to filter a dataset to only visualize data linked to a specific reference space, see here.

However, in addition to filtering for data linked to a reference space it is also useful if we can apply a geospatial restriction to a data visualization. For instance, let's say we have data on 10 different wastewater treatment plants. Instead of being able to filter by specific WWTP, I would like to be able to filter data to only include those WWTPs that are located within a specific boundary (say a municipality). The system should then filter data based on the location of the WWTP.

Features was now built. Notes:

  • It only shows for secondary visualizations - it will be too confusing if the main data viz is being geospatially filtered
  • Upon entering an ID, the system will check to make sure it's valid (it exists and contains boundaries). If it isn't, an error will be shown
  • Like the other ones, the GENERATE PREVIEW part isn't changed - needs front-end work
  • I have added a little info box (? where people can move the mouse over) that explains how to use this within the chart editor

Sidenote: you can also generate an "on-the-fly" geospatial restriction by adding "?boundaries=XXXX" to the URL of a data visualization.
