Jerome Baton

Jérôme Baton started hacking computers at the age of skin problems, gaming first then continued his trip by self-learning Basic on Amstrad CPC, peaking on coding a full screen horizontal starfield, and messing the interlace of the video controller so that sprites appeared twice as high in horizontal beat'em up games. Disks were three inches for 178 Kb then. Then, for gaming reasons, he switched to Commodore Amiga and its fantastic AMOS Basic. Later caught by seriousness and studies, he wrote Turbo Pascal, C, COBOL, Visual C++, and Java on PCs and mainframes at university, and even Logo in high school. Then, Java happened and he became a consultant, mostly on backend code of websites in many different businesses. Jérôme authored several articles in French on Neo4j, JBoss Forge, an Arduino workshop for Devoxx4Kids, and reviewed kilos of books on Android. He has a weakness for wordplay, puns, spoonerisms, and Neo4j that relieves him from join(t) pains. Jérôme also has the joy to teach in French universities, currently at I.U.T de Paris, Université Paris V - René Descartes (Neo4j, Android), and Université de Troyes (Neo4j), where he does his best to enterTRain the students. When not programming, Jérôme enjoys photography, doing electronics, everything DIY, understanding how things work, trying to be clever or funny on Twitter, and spends a lot of time trying to understand his kids and life in general.

What is so spatial then?

The answer is:  

Neo4j is spatial, APOC is spatial too, and of course, Neo4j Spatial is more spatial. Let me explain.

Spatial capabilities are present in these three pieces of software. Their spatialness goes from basic to advanced in that order.

However, as the last two (APOC and Neo4j Spatial) are plugins that you install in the first software (Neo4j), spatial features add up. The package names change in order to call the procedures. We will see this now.

Neo4j's spatial features 

Neo4j has a limited built-in spatial support since Neo4j 3.0. There is default support for point and distance. This support assumes that you will set property keys named latitude and longitude for the nodes you want to use as points.

You can use them to calculate the distance between two nodes, but first let's build the towers, starting with the good habit of creating a constraint:

CREATE CONSTRAINT ON (t:Tower) ASSERT t.name IS UNIQUE
CREATE (paris:Tower {name: "Eiffel Tower",country:"FRA"...
