Key Issue: It is estimated that over 1 million spatial data sets on 30,000 internet map servers are now posted by government agencies, Universities, and private organizations. A substantial number of these map data layers could be useful for wildland threat assessment and mapping. However, functional search engines to locate, assess, and connect to these data do not exist. In this project, we built an internet search engine and integrated it within a virtual earth viewer to assess global spatial data sets for studying the spatial distribution and co-occurrence of various wildland threats and the values they affect. The system allows integration of internet and corporate spatial data to permit integrated analysis and exploration of wildland threats and values impacted.
Description of Work: The search engine is integrated within the new ArcGIS Explorer, a virtual globe viewer like Google Earth. However, ArcGIS Explorer can connect to a range of spatial data sources (Agency servers, local files, internet map servers), and, most importantly, perform geo-processing tasks to analyze spatial relationships.
ArcGIS Explorer provides a novel way to perform integrated threat mapping where spatial data must be acquired and integrated from multiple sources. For instance, Forest Service spatial data on wildfires, forest insects, climate projections, and invasive plants are housed and managed by different agency units and conjointly viewing these data to examine potential interactions is not possible. Furthermore, locating and overlaying internet map data is not possible. The WWETAC threat mapper facilitates the integration of these data sets
The Google-like spatial data search engine queries global internet map servers based on user keywords (image right). The search returns an array of information about data sources that match the query. The query result is used to connection to the map server is established and the map data loaded into ArcGIS Explorer. The search engine will be used to conduct a systematic assessment of internet data relevant for threat assessments.
