Large scale road network generalization for vario-scale map
The classical approach for road network generalization consists of producing multiple maps, for a different scale or purpose, from a single detailed data source and quite often roads are represented by line objects. Our target is the generalization of a road network for the whole scale range from large scale, where roads are represented as area objects, to mid and small scales, where roads are ...
متن کاملA Road Map for the Global Elimination of Congenital Syphilis
Congenital syphilis is the oldest recognized congenital infection, and continues to account for extensive global perinatal morbidity and mortality today. Serious adverse pregnancy outcomes caused by maternal syphilis infection are prevented with screening early in pregnancy and prompt treatment of women testing positive. Intramuscular penicillin, an inexpensive antibiotic on the essential medic...
متن کاملA global road map is needed for vaccine research, development, and deployment.
The world is witnessing a tremendous interest in the discovery, development, and use of vaccines as an important contributor to disease prevention and control. However, current global vaccine efforts are not coordinated, and they face many challenges. One is scientific: Most vaccines in use today are based on the scientific knowledge of past centuries. To usher in a new era, there is an urgent ...
متن کاملMulti-scale Road Extraction Using Local and Global Grouping Criteria
In this paper we combine two approaches for road extraction. The first approach makes use of multiple scales to detect roads segments and employs local grouping criteria and also context information to extract the road network. This approach is suitable for aerial imagery with a resolution of 0.2–0.5 m. The second approach was designed to extract roads from satellite imagery and can be applied ...
متن کاملRepair road map
A report on page 195 by BekkerJensen et al. maps out the damage-induced rearrangement of proteins involved in repairing doublestranded DNA breaks (DSBs). The map, the authors hope, will help scientists assign functions to future putative damageresponsive proteins. Treatments such as ionizing radiation (and chemotherapy) that induce DSBs lead to the accumulation of nuclear foci containing repair...
