Fundamentals of Photogrammetry
Like in many other disciplines, there is no universally accepted definition of the term photogrammetry. The Manual of Photogrammetry (2003) defines photogrammetry as the art, science, and technology of obtaining reliable ...
Fresh water is one of the basic necessities without which human beings cannot survive since water is key to the sustainability of all kinds of lifeforms. Water has multiple uses namely; nutritional, domestic, recreational, ...
Optical Remote Sensing
There are a large variety of systems for collecting remotely sensed data in operation today.
Data Models and Structure
By convention, data in the real world is deemed to exist in a continuous or analogue form usually in three dimensional space as discussed in Sect. 2.1. Such data needs to be digitized or made discrete before it can be input ...
The Global Positioning System
The Global Positioning System or GPS is the oldest and most widely used GNSS system, and as such will be extensively discussed in this and the next chapter. The development of GPS satellites dates from the 1960s.
One of the most fundamental developments in the history of photogrammetry has been the transition from analytical to digital photogrammetry. This was realized in the early 1990s through softcopy-based systems or Digital ...
Weather, Climate and Global Warming
In order to fully appreciate the contribution of geoinformatics in monitoring climate change caused by increase in temperature, a distinction between weather and climate, on one hand, and climate variability and climate ...
Environmental Monitoring and Management
A natural way to begin this monogram is by posing several pertinent questions. Firstly, what exactly does the term “monitoring” mean. Furthermore, is monitoring synonymous to measuring or observing? And more specifically, ...
Environmental Impact Assessment
Environmental Impact Assessment (EIA) is defined by Munn (1979) as the need to identify and predict the impact on the environment and on man’s health and well-being of legislative proposals, policies, programs, projects, ...
Input of GIS Data
Precisely because of the expensive cost of GIS data capture and the fact that the procedures involved in this are also fairly time consuming, the sources for GIS data should always be carefully analyzed before selection ...
