Unfolding SimpleMapApp - Image files missing

Question

I am working on an application which uses unfoldingmaps with processing.

Below is the sample code from unfolding in processing

import de.fhpotsdam.unfolding.*;
import de.fhpotsdam.unfolding.geo.*;
import de.fhpotsdam.unfolding.utils.*; 

UnfoldingMap map;

void setup() {
    size(800, 600, P2D);
    map = new UnfoldingMap(this);
    MapUtils.createDefaultEventDispatcher(this, map);
}

void draw() {
    map.draw();
}

This is the error message I am getting

I tried hitting the url from the browser - it says image files have been moved. Should I get a dump of this in my local system? How does this work? Do these URLs work for others using unfolding?

Answer 1

This is the modified version of example code.

import processing.core.PApplet;
import de.fhpotsdam.unfolding.UnfoldingMap;
import de.fhpotsdam.unfolding.geo.Location;
import de.fhpotsdam.unfolding.utils.MapUtils;
import de.fhpotsdam.unfolding.providers.Google;
public class HelloUnfoldingWorld extends PApplet {

    UnfoldingMap map;

    public void setup() {
        size(800, 600, OPENGL);

        map = new UnfoldingMap(this, new Google.GoogleMapProvider());
        map.zoomAndPanTo(10, new Location(52.5f, 13.4f));

        MapUtils.createDefaultEventDispatcher(this, map);
    }

    public void draw() {
        background(0);
        map.draw();
    }

}

I have added

import de.fhpotsdam.unfolding.providers.Google;

and modified

map = new UnfoldingMap(this, new Google.GoogleMapProvider());

Now it is working

For some weeks, the map tile service Unfolding uses as default did not respond properly as they moved to WikiMedia Labs. Now it redirects, and serves the tile images again.
