We asked Katie some questions to uncover her Mapillary story.

Why are you using Mapillary?

I get frustrated when the maps cooked up by regional planning agencies do not tell the truth that I see on the ground. I want local non-government groups to have access to data and tools so that we can be strong negotiators for building a pedestrian-friendly city.

Mapillary reminds me of where I've walked, and where you might walk, or not, if the path is too muddy and bumpy. Mapillary creates a visual network of walkable places. A Mapillary track promotes great walks or energizes us to build missing walkways. It makes the technology affordable and easy to use for community groups.

Tell us about your favourite sequence

We wanted a new crosswalk between senior housing and a mall. This sequence shows my illegal (jay-walking) crossing via a well worn path.

A year later the city installed a cross-walk. I should update Mapillary with a new sequence, and send a thank you to the city.

How did you get hooked on Mapillary and what is your favourite part?

A conversation with Johan at State of the Map 2014 (an annual meeting for OpenStreetMap contributors) convinced me that it was easy and affordable to use.

What would you like to tell others about Mapillary?

It is easy to use, requires only one app installation, only one new login. The mapping and processing is done automagically.

What is your best Mapillary tip for newcomers?

Charge your device before you leave home. Be bold. You will learn how to avoid foot photos. With practice, your photos will improve. So will Mapillary.
