Hazard Map for Japan

[Ben Wyss]

Create a hazard map for Japan. There are two models 21 and 22. Both maps need to be rendered for the whole model area and cut to the land area

To create the hazard map for Japan I first converted the xml files into csv, then imported them into QGIS and saved them as shapefiles. I then applied a spatial index to the shapefile using mapnik.

Next I created a contour of the map using the QGIS contour plugin.

Next I imported the shapfiles into tilemill and used the following catocss:

#hazard_cut_contour_22 {
  line-width:1;
  line-color:white;
  line-opacity:.4;
  //line-join:round;
  //line-gamma:1;
  //line-join:round;
  line-smooth:1;
  [zoom = 7]{
    line-width:2;
   line-color:white;
   line-opacity:.3;
  }
  [zoom = 8]{
    line-width:4;
   line-color:white;
   line-opacity:.5;
  }
}

#hazard_japan_22_cut {
  marker-allow-overlap:true;
  marker-line-color:orange;
  //marker-line-opacity:0.3;
  marker-width:5;
  marker-line-width: 3;

I then cut the vector data so that I was left with only the data for points on land. I made another contour and compiled tiles sets with tilemill
