A close companion to CW's development of a new Green Vision is to advance the mapping tools that depict and support it. CW has always leaned on good maps of the region, whether in two editions of the Atlas of Biodiversity, two versions of the Green Infrastructure Vision, maps of Oak recovery, or maps that framed the conservation possibilities in the Calumet region. But it's now almost a decade since CW systemically updated its mapping capacity, and new developments in data, in mapping platforms, and in public engagement make this an urgent priority for the Alliance. On October 27, a Cafe was held to gather folks interested in some next steps in mapping, with topics including a potential new interface (or "hub") for mapping products, how the hub can be the place to track progress on Green Vision goals, and possible new sources of data. More than 50 people attended and showed strong interest. A next Cafe is scheduled for January 28, 12-1, at which Mark Johnston, GIS Manager at the Field Museum, will display more of the capacities of the hub as a potential shared resource for the Alliance. A working group including representatives from CMAP, NIRPC, SEWRPC, Openlands, Argonne, TetraTech, and the Field Museum has guided the conversation so far; in 2021 new ways to engage in the process will be developed in concert with the further articulation and implementation of CW's Green Vision goals.
