Help with multiple regions in Regionmapping.json not working

[Andrés Maldonado]

Hello there,

I hope you can give me a hand on this as I'm stucked and out of options  here:

I've set up a region that loads vector tiles. It works well whenever I just use one item in the regionWmsMap key, but if I add another item, then only the first item from the top gets loaded over the map when adding its related data. If I switch the order, the first item will be rendered but not the second one.

I've added my project to the following repo: https://github.com/rulight/hilzip

Or if you want to give a quick look to my regionmapping.json, here it is:

{

  "regionWmsMap": {

    "HIL_ZIP_2010": {

      "layerName":"HIL_ZIP_2010",

      "server": "http://tad3tiles.tad3.org/HIL_ZIP_2010/{z}/{x}/{y}.pbf",

      "serverType": "MVT",

      "serverMinZoom": 8,

      "serverMaxZoom": 11,

      "regionIdsFile": "data/regionids/region_map-HIL_ZIP_2010.json",

      "regionProp": "GEOID10",

      "nameProp":"Name",

      "aliases": ["GEOID10"],

      "description": "HIL ZCTA",

      "bbox": [

        -82.82366904, 

         27.57054998,

        -82.05401201,

         28.17337897

      ]

    },

    "DES_ZIP_2010": {

      "layerName":"deszip2010",

      "server": "http://tad3tiles.tad3.org/deszip2010/{z}/{x}/{y}.pbf",

      "serverType": "MVT",

      "serverMinZoom": 8,

      "serverMaxZoom": 11,

      "regionIdsFile": "data/regionids/region_map-DES_ZIP_2010.json",

      "regionProp": "GEOID10",

      "nameProp":"Name",

      "aliases": ["GEOID10"],

      "description": "DES ZCTA",

      "bbox": [

        -82.2274830000000065, 

        27.0317000000000007,

        -81.5621840000000020,

        27.3407020000000003

      ]

    }

  }

}

I'd really appreciate your help on this one.

Cheers!

Hi Andrés,

The aliases you assign to different region types should be unique. They are used to match a column in a CSV to the region type and that doesn't work if the aliases aren't unique. If for some reason you can't change the CSV column names and you have to use them as is you can force the CSVs to use the correct region type in catalog json:

{
    "type": "csv",
    "tableStyle": {
        "regionType": "DES_ZIP_2010",
        "regionVariable": "GEOID10"
    }
}
