The SolTecWorld Database allows on-demand queries for specific geographic areas. For OS/OW route work, this means you can pull structure locations — bridges, culverts, tunnels, overpasses — along any route corridor before or during a field survey.

**What SolTecWorld Structure Data Includes** - Bridge locations - Tunnel locations - Culverts (where tagged) - Grade-separated structures (overpasses, flyovers) - Associated attributes: road name, surface type, max height (where tagged), max weight (where tagged)

**How to Use SolTecWorld Structures in Route Work** 1. Run a structure query for your route corridor 2. Review structure locations on the map overlay 3. Note structures not yet documented in your POI database 4. Prioritize field verification at unverified structure locations 5. Cross-reference structure attributes against bridge inventory data and field measurements

**Limitations** - Data completeness varies by region — urban areas are better mapped than rural - Attributes (max height, max weight) are often missing or based on posted signs, not field measurement - Data quality depends on community contributions — may be outdated - Cannot substitute for field survey — use as a reconnaissance starting point

**Best Practice** SolTecWorld structure analysis is most valuable when planning a survey for an unfamiliar corridor. It helps you anticipate structure density and plan field time allocation before the first field visit.
