| Standard | Metadata Endpoint | Discovery Info | |----------|------------------|----------------| | | ?SERVICE=WMTS&REQUEST=GetCapabilities | TileMatrixSet, bounding box, formats, URLs | | TileJSON | /tilejson.json | bounds, min/max zoom, tile URL template | | XYZ / Raster tile | Implicit or links.json | None – requires active probing | | ArcGIS REST | /MapServer?f=json | tileInfo, LODs, spatial reference | | TMS (OSGeo) | /tms.xml | Profile, tile origin, extent |
This process is critical for geospatial asset management, security auditing (exposed tile servers), and dynamic integration of mapping layers into GIS applications. | Concept | Description | |---------|-------------| | Tile | A small raster (PNG/JPEG) or vector (PBF/MVT) image representing a geographic area at a specific zoom level. | | Tile Matrix | A grid of tiles; origin (usually top-left or bottom-left) varies by standard. | | Tile Server | An HTTP endpoint that serves tiles based on URL patterns (e.g., /z/x/y.png ). | | Tile Set / Layer | A collection of tiles forming a complete map layer. | | Service Metadata | Capabilities document (WMTS GetCapabilities , TileJSON, or HTML link headers). | 3. Discovery Methods Webtile Network Discovery can be performed using active probing , passive observation , or metadata harvesting . 3.1 Active Discovery (Probing) The system actively sends requests to likely tile endpoints and analyzes responses.
1. Executive Summary Webtile Network Discovery refers to the automated process of identifying, mapping, and monitoring tile-based web mapping services (e.g., XYZ, TMS, WMTS) within a given network or software ecosystem. Unlike traditional network device discovery (which finds IPs, hosts, and ports), Webtile Discovery focuses on geospatial data endpoints, their schemas, zoom levels, coordinate bounds, and availability.
