Global Water Human Needs

Global Water Human Needs

Introduction

Water is essential for the existence of life and is closely related to many aspects of survival, needs and human activities. From a physical perspective, plays a leading role at the global level to form the hydrosphere and occupy approximately 70% of the global area, being a fundamental element of the configuration of the different territories, being also present in the subsurface and atmosphere, and can be found in all possible states (solid, liquid and gas). Water is a limited resource that is developed in a natural way by the so-called Water Cycle or Hydrologic Cycle, characterized by processes of evaporation, condensation and precipitation. This means that the water that circulates around the planet from the moment he appeared in it and, therefore, is a renewable resource and quantitatively essentially permanent (Mirosa, Harris, 2012).

System Mapping

By re-using the graphical environment coordinate system mapping rules, an application can create real-world constraints from the logical coordinate system. By default, the device is equal to a logical unit of a pixel, but the application of a logical unit may also represent other scale - for example, one millimeter or a pixel 600dpi printer. By using the logical coordinate system, the application program can process of drawing from the target device in the actual separation of the pixel resolution. Coordinate system defined mapping mechanism includes two rectangles: the window, define the logical coordinate space of a rectangle, the viewport, defines the target device in a rectangle. These two rectangular units and equipment to establish a logical unit of proportion - window unit pixel size in the viewport, and vice versa. Similarly, the window origin directly mapped to the viewport origin.

Coordinate system is not affected by the rectangle defined limit, which is the establishment of two rectangles only a proportion rather than a specific size.

GDI allows applications to create the window and viewport rectangle, you can choose one of the predefined settings. Windows defines eight mapping mode; six have predefined settings, you can make two applications have some mobility. When the DC coordinate mapping is established, the next program code must be noted that it is only used in the logical coordinates.

A survey seeks some form of rationality, where the success lies in an appropriate balance between aggregation and detail description regarding both an- century included actors and the processes they are involved in. A survey of social phenomena requires a greater degree of "theory" than the mapping of natural topography. The "theory" or the system definition suggests which items should primarily included , which actors can be included but are of "secondary" interest and, as is often forgotten, and which actors are excluded from the survey. The "theory" can also facilitate preliminary analysis by sorting operators for different qualities and quantities. In our case, the definition of "innovation tem "material and then even the concept of innovation. Below is a brief conceptual review as background to the definition of- limit in this survey
