Company preparing map app of Pittsburgh’s steps

ESRI is a mapping services company whose software is used by governments, corporations, institutions and disaster relief organizations around the globe. But it is going hyperlocal in Pittsburgh.

Sixty-six of the city’s 90 neighborhoods have at least one set of hillside steps. There are 716 sets in all, and the Slopes has the most with 66.
Step Trek is in its 13th year as a fundraiser for the neighborhood association. As many as 1,100 people have taken tours of the hillside steps in past years.
