cpsd

cpsd is a database to develop Church planting strategy. It is originally created for mission organizations around the world to plant Churches in Japan - the couontry with world's second largest unreached people group.

Background

I converted from atheist physics fanboy to evangelical Christian when I was a student of ICU (International Christian University). Changed my major from physics to computer sciencce as I felt CS is pragmatically more usuful for world evangelism. At that time I also started an internship at Christian Today Japan as Full Stack Developer and reporter. I moved from Japan to US to earn Master of Arts in Information Technology from OIT (Olivet Institute of Technology) while majoring Missiology and Software Engineering together. Primary interest was to leverage tech for world mission strategy all the way from micro strategy like locating Church absent cities to macro strategy like global interindustrial logistics. After serving as a minister of G&IT (Gospel & Information Techcnology) in United States, I moved back to Japan to work as editor in chief of Christian Today Japan. Intersection of Christianity, Journalism and Information Technology has been my field. I was always interested in the advancement of Data Journalism. Now that I spent 1 year in the world of online Christian Journalim and FaithTech, came to know almost nobody practice Data Journalism in our field. That was the moment I felt God called me to be the first one to do that. First topic I chose was meant for something useful for World Mission Strategy.

Current Project

Now at the starting point, cpsd is limited to for the usage in mission strategy in Japan in English. First dataset is location of Churches and train stations with passenger count and distance.

Technical Architecture

cpsd is a combination of Kotlin functions meant to be executed in integrated development environment (IDE) with running local Neo4j instance at localhost.

Setup and Run

  1. Download Neo4j Desktop, create a database with your choce of password, and install APOC.
  2. Prepare churches.csv with header url,catholic,lat,lng,address,name.
  3. Prepare stations.csv with header id,lat,lng,name,company,line,passengers2017.
  4. In Neo4j Desktop, Your Project-> Click "⋯" Dropdown->Open folder->Import copy and paste churches.csv and stations.csv in Import directory.
  5. Open Neo4j Browser and run Query 1-4 in Cypher file to import csv into Neo4j.
  6. Import this repo into your IDE and create db.properties with 2 lines: username = neo4j and password = NEO4J_PASSWORD_YOU_CREATED_IN_STEP_1 in resources
  7. Run main() in Route.kt this will generate routes.csv in resources
  8. Copy and paste routes.csv in Import directory and run Query 5 in Neo4j Browser.
  9. In your IDE, run main() in StationWithChurch.kt to generate GeoJson files of stations with Churches.
  10. In your IDE, run main() in StationWithoutChurch.kt to generate GeoJson files of stations without Churches.
  11. In your IDE, run main() in Churches.kt to generate GeoJson files of all Churches.

Resulted files

GeoJson files are separated by GeoJson FeatureCollection, Churches and Stations are Point, Stations are also Polygon, Route from Station to Church is LineString. Files are also separated into 6 distance segments from 0 to 500, 1000, 1500, 2000, 2500 or 3000 meters. Following are the expected files to be generated:

500-church.json
500-route.json
500-station-point-with-church.json
500-station-point-without-church.json
500-station-polygon-with-church.json
500-station-polygon-without-church.json

1000-church.json
1000-route.json
1000-station-point-with-church.json
1000-station-point-without-church.json
1000-station-polygon-with-church.json
1000-station-polygon-without-church.json

1500-church.json
1500-route.json
1500-station-point-with-church.json
1500-station-point-without-church.json
1500-station-polygon-with-church.json
1500-station-polygon-without-church.json

2000-church.json
2000-route.json
2000-station-point-with-church.json
2000-station-point-without-church.json
2000-station-polygon-with-church.json
2000-station-polygon-without-church.json

2500-church.json
2500-route.json
2500-station-point-with-church.json
2500-station-point-without-church.json
2500-station-polygon-with-church.json
2500-station-polygon-without-church.json

3000-church.json
3000-route.json
3000-station-point-with-church.json
3000-station-point-without-church.json
3000-station-polygon-with-church.json
3000-station-polygon-without-church.json

Data for stations and Churches in Japan are located at data/japan directory in this repo.

Visualization

You can import those GeoJson files into GIS software or services like MapBox Studio. For example, Church & Station project at Christian Today Japan.

Future

Hoping to apply for other countries, accomodate other type of data and languages.
