A system and method for automatically georeferencing digitized images selects and analyzes image landmark points from disparate sources for image co-registration. A composite alignment of raster images and geographic target vectors is automatically generated using metadata sources for use in geographic display and editing environments. Cartographic alignment of raster images to geographic vector data sets is performed to co-position image data with geographic vector data sets. The co-registration and display permits a meaningful overlay of the data sets and an improved comparison of vector data to the correctly-registered images based on the physical relationships between the vector data and the underlying image features. By incorporating metadata regarding landmarks and other points of interest, users may query target vectors to display attributes of the associated landmarks and create a highly accurate parcel map for validating image information in areas where the data was acquired in sub-optimal conditions.

The present invention provides a maintenance support system for a construction machine that allows a components maintenance schedule to be accurately established.

The system 1 calculates the cumulative load of every component corresponding with the driving and working conditions of the construction machine 3 by means of the load calculation means 13 after simulating the driving and working conditions on the basis of production operating conditions by means of the operation simulation means 12, and forecasts the lifespan of the respective components by means of the lifespan calculation means 14 on the basis of the cumulative load. Hence, a more accurate maintenance schedule can be established in comparison with a case where which component is to be maintained is determined on the basis of only the operating time as in the prior art. The possibility of an unexpected component anomaly occurring at an earlier stage than the predetermined lifespan can therefore be reduced.
