GeoArrow MultiLineStrings (deck.gl-geoarrow)

Name: @geoql/v-maplibre
Availability: InStock

Country boundary rings from a GeoArrow IPC file. Each country's border is encoded as a MultiLineString (a list of coordinate rings) and streamed directly to the GPU.

<script setup lang="ts">
  import { VMap } from '@geoql/v-maplibre';
  import { VLayerDeckglGeoArrowPath } from '@geoql/v-maplibre/deck.gl';
  import { tableFromIPC } from 'apache-arrow';

  const table = shallowRef(null);
  onMounted(async () => {
    const url = '/geoarrow/natural-earth_countries-bounds.arrows';
    const buffer = await (await fetch(url)).arrayBuffer();
    table.value = tableFromIPC(new Uint8Array(buffer));
  });
</script>
