[mkgmap-dev] DEM There is not enough room in a single garmin map for all the input data

Wed Sep 2 11:18:42 BST 2020

I was created from data from:
http://geojson.io/#map=2/20.0/0.0
{
  "type": "FeatureCollection",
  "features": [
    {
      "type": "Feature",
      "properties": {},
      "geometry": {
        "type": "Polygon",
        "coordinates": [
          [
            [
              94.921875,
              -55.77657
            ],
            [
              189.84375,
              -55.77657
            ],
            [
              189.84375,
              -7.362466
            ],
            [
              94.921875,
              -7.362466
            ],
            [
              94.921875,
              -55.77657
            ]
          ]
        ]
      }
    }
  ]
}

Thanks for looking at this.
Joao
