An algorithm for locating candidate labeling boxes within a polygon
Jan W. van Roessel
1989, American Cartographer (16) 201-209
Vector-based geographic information systems usually require annotation, such as a polygon number or attribute data, in a suitable location within a polygon. Traditional methods usually compute the polygon centroid, test the centroid for inclusion or exclusion, and select some alternative point when the centroid falls outside the polygon. Two problems...
Remote characterization of marine bird habitats with satellite imagery
J. Christopher Haney
1989, Colonial Waterbirds (12) 67-77
Remote sensing techniques such as radar altimetry, synthetic aperture radar, coastal zone color scanning, and infrared radiometry provide effective, instantaneous, and relatively inexpensive means for characterizing critical habitats of marine birds.

Iterative techniques for characterizing marine bird habitats with time-series of satellite images
J. Christopher Haney
1989, Colonial Waterbirds (12) 78-89
Demonstrating long-term habitat use of marine habitats by seabirds is often complicated by short-term changes in habitat locations, persistence, and age. This paper describes iterative techniques for characterizing non-static habitats, such as meso-scale (10-100 km) ocean eddies and fronts, using time-series of satellite images that define sea surface conditions. Seabird...

Ray E. Wells
1989, Book chapter, Paleomagnetic rotations and continental deformation. NATO ASI Series (C: Mathematical and Physical Sciences)
Large clockwise rotations (15–80°) are characteristic of Cenozoic volcanic and sedimentary rocks along the convergent margin of the northwestern United States. Abundant paleomagnetic data from 62–12 m.y. old rocks in forearc, arc, and backarc regions show that rotation increases with age and with proximity to the coast. Paleomagnetic and structural...
