You Are Being Tracked!

Here is a scary report from New York Times on how our personal locations are being tracked, and mostly from unregulated location data companies that cross reference your location with other databases to figure out who you are, where you live, and where you have been.

“In one case, we observed a change in the regular movements of a Microsoft engineer. He made a visit one Tuesday afternoon to the main Seattle campus of a Microsoft competitor, Amazon. The following month, he started a new job at Amazon. It took minutes to identify him as Ben Broili, a manager now for Amazon Prime Air, a drone delivery service.”

The Living Atlas of the World

ESRI’s ArcGIS Living Atlas of the World can be described as an evolving collection of authoritative, curated, read-to-use global geographic information curated by ESRI and the GIS user community.  It includes imagery, basemaps, demographics and lifestyle, landscape, boundaries and places, transportation, earth observations, urban systems, oceans, and historical maps, all of which can be combined with your own data.

Most can be used without signing in, but you will need an ArcGIS Online account for the more interesting ones.  Here are a few I found that were interesting.  Continue reading

Mapping Indigenous LA

The Mapping Indigenous Los Angeles project from the University of California Los Angeles is creating a series of story maps that bring together a variety of stakeholders to help highlight “multiple layers” of diversity and identity.  At the heart of the site are the story maps themselves, which unfold to reveal the complex history of place and the Indigenous peoples who have helped shape and been shaped by them.  The story maps vary in length and depth, but all feature a variety of text, photos, podcasts, and other materials that help viewers immerse themselves in the subject matter and deepen their understanding.  Check it out!

The Large and Goodly Island of California

BriggsNorthAmerica1625This 1625 map by British mathematician Henry Briggs initiated one of the most famous of all cartographic misconceptions, California as an island, which persisted until the end of the 17th century. This idea is thought to have originated with the Carmelite friar, Antonio de la Ascension who accompanied Sebastian Vizcaino on his West Coast expedition of 1602-03, and wrote an account of the trip. About 1620, it is believed that Father Ascension drew a map depicting California as an island and dispatched it by ship to Spain. The ship was captured by the Dutch and the chart taken to Amsterdam.

In 1622, California appeared as an island on two title page vignettes published in Amsterdam by Michiel Colijon: Jacob le Maire’s Spieghel Der Australische Navigatie and Antonio de Herrera’s Descriptio Indw Occidentalis. That same year in London, Henry Briggs published an article entitled “A treatise of the Northwest Passage to the South Sea, through the Continent of Virginia, and by Fretum Hudson.” Briggs claimed to have seen a map in London brought from Holland showing California as an island. His article was republished slightly modified in 1625 in Purchas’ Pilgrimes, and was accompanied by this map supposedly drawn from the one “taken by Hollanders.” A similar map engraved by Abraham Goos was inserted into a small book published in 1624 in Amsterdam. Although dated earlier, it is likely that this map used the Briggs map as a source.

Briggs’ map quickly became a model for others. John Speed copied it in 1626-7 as did Joannes Jansson in 1638, and soon nearly all European cartographers depicted California as an island. One purpose of the map was to suggest the probability of a short passage from Hudson Bay to the Pacific Ocean, which was enhanced cartographically by the absence of a northern coast and land to the west, which were common features of maps up to that time.

11561004A Jesuit friar, Eusebio Kino, was the first to offer proof against the island theory using the map he compiled in 1701, which was printed in 1705 in Paris. Kino’s map was not readily accepted and it eventually required a royal decree by Ferdinand VII of Spain in 1747 to state that “California is not an Island.”
