Make a cross stitch style map in ArcGIS Pro

Yes, yes, maps are spatial communication devices and we can obsess over precision and clarity. But it all depends on your map’s purpose. Maps are also designed objects so they can carry within them the power of sentiment. Memory, joy, nostalgia. Or just plain old wonder and curiosity. Here’s how you can create a charming …

van Gogh style wind map

Here’s how to use compositing to tint flowing wind patterns by underlying terrain colors. Why? Because rather than a basemap providing some context around a layer that inherently blocks your view of it, you can leverage the amazing compositing blend modes of the ArcGIS Online Map Viewer to make the phenomenon reveal context rather than …

Hack some bokeh into your ArcGIS Online map

You know how you can crank up the sense of drama and studio photography professionalism by switching over to portrait mode on your phone’s camera? It just looks…cool. The subject is in focus and the peripheral background content is blurry. It’s actually how our eyes and brains work, so it’s pleasing to see in photography. …

Taming the Frontier, Part 2

The drive up to Michigan was something I did for myself, and I visited a number of historical and cultural sites along the way. But I took the trip to drive a kid home for the summer and now I had a passenger for the rest of the ride. So I front-loaded most of the […] The post Taming the Frontier, Part 2 appeared first on Twelve Mile Circle - An Appreciation of Unusual Places.

The First Ghetto

The first ghetto was established in 1516 in Venice, Italy. Jewish residents were forced to live in a small industrial area by the government and locked in at night. Here is a picture of a ghetto map from I took while there a few weeks ago.  According to the sign Jews were only allowed to work as doctors, money lenders or second hand clothing sellers. The ghetto was expanded to two squares, the Ghetto Vecchio (old, which is actually the newer one) and Nuovo (new). After the French took over Venice in 1797, Jews were finally allowed to freely move about the city but this area remained a center of Jewish culture. It still is despite most of Venice’s Jews having been murdered in the Holocaust. There are still a handful of restaurants and places of worship. The origins of the word ghetto are disputed. It could mean foundry, street, little town or “throw away” depending on which theory you choose. Here is a simplified (but also hard to read) map of the area by artist Gianluca Costantini.
