This multimedia book and DVD kit covers the entire world! Featuring 160 ready-made maps of every country and major geographical area, it’s a revolutionary new resource for the home (to remember a vacation, for example) and the classroom. The DVD contains the maps themselves, each in the form of a PC and Mac-friendly Photoshop file. Inside the book, there are simple instructions for adapting those maps to your own requirements, and then printing them out, distributing them, or publishing them online. All the maps contain 15 different Photoshop layers, offering a wide choice of cartographic styles, and you can turn country borders, place names, and other elements on or off at will. Every map will print perfectly on a desktop printer, fits on letter-sized paper, and can easily accommodate added graphics, photos, or text.
This report deals with the modelling of the behavior of the LaCoste Romberg G Gravity Meter. This is accomplished by using a model which includes a linear term plus a long wave sinusoidal term to represent the calibration information contained in the Calibration Table 1 supplied with each gravity meter. Additional sinusoidal terms are added to model any periodic screw error effects. Using gravity meter data collected for the United States Gravity Base Station Network with the majority of the data being along the Mid-Continent Calibration Line, various models were tested. The control used were absolute gravity station values determined by the Italians, Marson and Alasia, and by Hammond of AFGL. The results indicate the presents of periodic screw error terms having a period of approximately 70.941 counter units with amplitudes less than 20 micro gal and the estimated accuracy of gravity meter observations to be from 20-25 micro gal. Due to the inconsistencies of the absolute gravity station determinations, the accuracy of the absolute values is probably closer to 20 micro gal than the purported 10 micro gal. (Author).
