Visualize Neo4j-Spatial database in a map - neo4j

Question

I've been able to import some shapefiles to Neo4j 2.3.1.
Now how do I view this data on a map?
I have tried the Wiki instructions on GeoServer and uDig, but both of them are outdated and I couldn't get it to work.
Is there any recent tutorial or other tool that can solve this problem?

Answer 1

I've used neo4j-spatial with Mapbox.js for visualizing geometries in a map.
For my use case I indexed US Congressional district geometries in neo4j-spatial then query the spatial index based on where a user clicks on the map, returning the closest district including the WKT string and the results of a Cypher query. To render the WKT polygon in the map I wrote a simple javascript function to parse that into an array of points to add a map annotation.
Here are some relevant code snippets:
Create the map and define a click handler for the map:
L.mapbox.accessToken = MB_API_TOKEN;
var map = L.mapbox.map('map', 'mapbox.streets')
.setView([39.8282, -98.5795], 5);
map.on('click', function(e) {
clearMap(map);
getClosestDistrict(e);
});
Handle mouse click
/**
* Find the District for a given latlng.
* Find the representative, commitees and subjects for that rep.
*/
function infoDistrictWithinDistance(latlng, distance) {
var districtParams = {
"layer": "geom",
"pointX": latlng.lng,
"pointY": latlng.lat,
"distanceInKm": distance
};
var districtURL = baseURI + findGeometriesPath;
makePOSTRequest(districtURL, districtParams, function (error, data) {
if (error) {
console.log("Error");
} else {
console.log(data);
var params = {
"state": data[0]["data"]["state"],
"district": data[0]["data"]["district"]
};
var points = parseWKTPolygon(data[0]["data"]["wkt"]);
makeCypherRequest([{"statement": subjectsQuery, "parameters": params}], function (error, data) {
if (error) {
console.log("Error");
} else {
console.log(data);
var districtInfo = data["results"][0]["data"][0]["row"][0];
districtInfo["points"] = points;
districtInfo["state"] = params["state"];
districtInfo["district"] = params["district"];
console.log(districtInfo);
addDistrictToMap(districtInfo, latlng);
}
});
}
});
Parse WKT into an array of points
/**
* Converts Polygon WKT string to an array of [x,y] points
*/
function parseWKTPolygon(wkt) {
var pointArr = [];
var points = wkt.slice(10, -3).split(",");
$.each(points, function(i,v) {
var point = $.trim(v).split(" ");
var xy = [Number(point[1]), Number(point[0])];
pointArr.push(xy)
});
return pointArr;
}
The code is in this repo. You can see the simple map demo here (just click anywhere in the US to get started). There is also a recent blog post about this example here.
