I discovered your Illustrator symbols to build a conceptual diagram. I work on EBM in New Zealand that focuses on integrating traditional and western management principles across the land and sea. A case study is the Kaipara Harbour and its catchment.
Can you create a base map for the Kaipara? It is southern hemisphere's largest estuary with dynamic sand dune peninsulas that allow an entrance of only 8km to the Tasman Sea, southern Ocean.
Thanks for your time.
