摘要:The Geographic Chart of Minas Geraes Province, by Caetano Luiz de Miranda, 1804, presents cartographic information data differentiating it from the coeval maps. This map causes perplexity for the author’s biographic data, an artist, notable in the Tejuco (presently Diamanti...

摘要:Digital Hydrographic Maps were developed by means of a geographic information system in order to predict how nesting islands for the American White Pelican ( Pelecanus erythrorhynchos ) are likely to become land-bridged under variable water levels on Clear Lake Reservoir, Califor...

摘要:This paper investigates how gray scale information can be used in a hydrographic map understanding system to improve the system performance. To process gray scale scanned map images, we have implemented a topographic analysis method and a binary analysis method. In addition, dec...

摘要:... A lake use plan is first developed from a hydrographic map depicting summer macrophyte growth and patterns of lake use. The lake is next zoned into areas of similar function. A management strategy is then tailored to each zone. Some lakes are managed for specific functions; o...
