Building a Web Map with Hosted Geospatial Data
Use hosted layers and a simple API to build fast web maps without managing servers or worrying about bandwidth spikes.
You can build a fast, responsive web map using only hosted layers and a simple API—no tile server to run, no bandwidth surprises if you pick the right host.
Stack choices
Use a JavaScript map library that supports standard tile URLs and, if needed, COG or GeoJSON: MapLibre GL JS, Leaflet (with plugins), OpenLayers, or similar. Your backend can be minimal: maybe a small API for search or filters, with the heavy lifting (tiles, vectors) coming straight from your hosting URLs.
Connecting to hosted layers
Point your map to the tile URL template (e.g. https://your-host.io/tiles/{z}/{x}/{y}.mvt) for vector tiles, or add a raster source with the COG URL for imagery. Many libs support these out of the box. Add a bit of styling and you have a working map. No need to pre-process or cache on your own infra.
Performance and cost
Vector tiles and COGs are designed for on-demand streaming, so initial load and pan/zoom can stay fast. If your host charges only for storage and not egress, you don’t have to worry about traffic spikes. That makes it easier to ship public-facing maps and iterate on design and data without ops overhead.
