In the work area, exploration has discovered large-scale Dongping gold deposit, small-scale Sandaogou galena/zinc deposit, and small-scale Yaoziwan iron deposit, etc. This survey focuses on the “Dongping-type” deposits. 1∶50 000-scale regional geologic and stream sediment surveys, etc. of ...

the attention of scientists was drawn to this field of study. A feature ofmarine science since the 1950s has been increasingly detailed bathymetric (water-depth measurement) surveys of selected portions of the seafloor. Together with collection of associated geophysical data and sampling of sediments...
of special devices called orthophotoprojectors. Orthophotographs, that is, aerial photos converted by this method, make possible the compilation of orthophotomaps for any region, thus significantly expanding the use of material from aerial photographic surveys for topographical, geological, and other ...
The map is supposed to be based upon actual surveys or rather reconnaissances, and if it be borne in mind that. the Roman Empire at that time was traversed in all directions by roads furnished with mile-stones, that the Agrimensores employed upon such a duty were skilled surveyors, and ...

While your plot may have been purchased as 1 acre, your actual property lines could make it slightly bigger or smaller depending on how and when it was surveyed. In addition, when installing things like fences, sometimes trees, large rocks, and other landscaping irregularities will change the...

Although map projections typically distort angles, ‘conformal’ projections show true angles as well as true shape within very small neighborhoods of every point: a property useful on small-scale weather maps, where angles between fronts, equal-pressure lines, and wind arrows are especially ...
However, these lines of work are complicated by the variety of problem-solving strategies students employ when solving mathematics problems and issues with generalizability. While some students may rely on a specific spatial ability to solve a particular mathematics problem, others may use non-spatial...
