Colour blind friendly mapping: where are we taking it next?

Following her blog on the release of two new colour vision deficiency (CVD) friendly styles for OS Open Zoomstack last December, Graduate Technical Consultant Jessica Baker talks through the feedback we’ve had, where our CVD mapping is going next, and new ways you can access these styles.

The initial release of the two new CVD friendly stylesheets in December 2019 was met with a keen interest, and you can find these stylesheets in a variety of file types on Github. Since then, we have been working hard to make more people aware of the benefits it could have for them. We’ve had lots of feedback from people and are excited to share with you the new direction we are taking this accessible mapping. Read More

Try our new OS Open Zoomstack styles for colour blind users

We’re looking for your feedback on our new styles for OS Open Zoomstack. They’re aimed at making our data more accessible to those with colour vision deficiency (CVD). Find out about the work that Jessica Baker, Graduate Data Scientist, has been doing on the styles and try them out for yourself.

Unless you’re colour blind, you are unlikely to be aware of the problems which cartographic styles and colour schemes cause for those affected by CVD. Colours usually easily distinguishable to the human eye, such as red and green, appear very similar and can make elements of map reading more difficult. The issue is often overlooked, with traditional spectral rainbow colour schemes kicking up several difficulties for those with colour blindness.

During my first few weeks at OS on the Graduate Development Programme, I’ve been learning how we can improve the accessibility of data. I decided to start by developing free downloadable styles for our popular OS Open Zoomstack product – an exciting project to work on.
