Simplifiying my geojson -> Uber h3 -> Neo4j processor; will port it to Hazelcast Jet, too.
This is a simplified version of my larger project, but it contains everything necessary to convert historical geoJson files to Uber H3 hex tiles.
There are some references to (:Year) nodes in the database. I have a calendar tree with Years, Months and Weeks made with this:
WITH range(1815, 2020) AS years
FOREACH (yr IN years |
MERGE (y:Year{name:toString(yr), began:date({year:yr, month:1, day:1}), ended:date({year:yr, month:12, day:31}),
last:date({year:yr, month:12, day:28}) })
SET y.weeksThisYear = y.last.week,
y.firstWeekBegins = date({year:yr,week:1}),
y.lastWeekBegins = date({year:yr, week:y.weeksThisYear})
FOREACH (wk IN range(1,y.weeksThisYear) |
MERGE (w:Week{weekYear:((yr * 100) + wk), forYear:yr})
SET w.name = toString(w.weekYear),
w.began = date({year:yr, week:wk}),
w.ended = date(w.began + duration('P5D') )
CREATE (w)-[:PART_OF{weekCount:wk}]->(y)
)
);
But, you could just create nodes for the few years connected to the data:
CREATE (:Year{name:"1815"})
CREATE (:Year{name:"1880"})
CREATE (:Year{name:"1914"})
CREATE (:Year{name:"1938"})
CREATE (:Year{name:"1945"})
CREATE (:Year{name:"1994"})
... and the results go something like this:
