The rest are likely only serving via ESRI standards. In reality, there are actually a lot more ArcGIS servers out there (at least ~4,900 in our index), but here we're only counting the ones that are serving WMS/WFS/WMTS/WCS. The first thing that jumps out is that ArcGIS has a huge number of deployments at 2,733, that's 53.7% of them.

UNSURE means it could be one of several things.

Type of geospatial server software and its count of deployments, as well as the number of hosted services and datasets provided by it. , and are two deployments) Service = A single service, the thing you get when you copy/paste a WMS/WFS/WCS/WMTS URL into your GIS. Note: Deployment = At least one instance of this software, grouped by domain (i.e. The question we're answering is: What's the most deployed software out there for serving up publicly accessible geospatial data via WMS, WFS, WCS, and WMTS services? While that may read like a lot of caveats, this isn't a tabloid newspaper! Here are the results in one big table. For example, the software that hosts the most datasets is easily GeoServer. But as ever with these things, there's a much more nuanced story to tell. After all, what's the point of having the world's largest index of geospatial web services at your fingertips (shameless plug!) if you're not going to use it to answer interesting questions? The answer is.

One of the things we've been meaning to do for a long time is investigate which geospatial server software is most prevalent for serving up all these services GeoSeer has in its index.
