Application of a computerized environmental information system to master and sector planning

A computerized composite mapping system developed as an aid in the land use decision making process is described. Emphasis is placed on consideration of the environment in urban planning. The presence of alluvium, shallow bedrock, surface water, and vegetation growth are among the environmental factors considered. An analysis of the Shady Grove Sector planning is presented as an example of the use of computerized composite mapping for long range planning.

Satellites to Lyman-alpha due to protons.

Using accurate H2(+) wave functions, the line broadening of the Lyman-alpha wings is calculated. Of particular interest are the linelike satellites which appear prominently at 1233.5, 1240.5, and 1404.9 A. No broadening of Lyman-alpha transition due to protons occurs at wavelengths below 965 A and above 1405 A.
