Vector data structure conversion at the EROS Data Center
Jan W. van Roessel, S. W. Doescher
1986, Open-File Report 87-309
With the increasing prevalence of GIS systems and the processing of spatial data, conversion of data from one system to another has become a more serious problem. This report describes the approach taken to arrive at a solution at the EROS Data Center. The report consists of a main section...

Thirty-three test holes were drilled along the Salt-Gila aqueduct...
Predictive spatial modeling of narcotic crop growth patterns
Frederick A. Waltz, D. G. Moore
1986, Open-File Report 86-7
Spatial models for predicting the geographic distribution of marijuana crops have been developed and are being evaluated for use in law enforcement programs. The models are based on growing condition preferences and on psychological inferences regarding grower behavior. Experiences of local law officials were used to derive the initial model,...
