What is Geobotanical mapping?
Geobotany is a well-established discipline and has been used since some years, as an aid in mapping geological formations and in locating fresh water, saline aquifers, and mineral deposits.
What is Geobotanical exploration?
Geobotanical prospecting refers to prospecting based on indicator plants like metallophytes and the analysis of vegetation. For example, the Viscaria Mine in Sweden was named after the plant Silene suecica (syn. Viscaria alpina) that was used by prospecters to discover the ore deposits.
What is remote sensing approach?
Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance (typically from satellite or aircraft). Special cameras collect remotely sensed images, which help researchers “sense” things about the Earth.
What is Phytogeography in botany?
Phytogeography is the study of the distribution of plants or taxonomic groups of plants and its focus is to explain the ranges of plants in terms of their origin, dispersal, and evolution (Matthews et al., 2003).
What are Geobotanical indicators?
Geobotanical indicators are either plant species or characteristic variations in the growth habits of plant species that are restricted in their distribution to rocks or soils of definite physical or chemical properties.
What tools are used for remote sensing?
Active Remote Sensing Instruments
- Radar is a sensor assisting in ranging with radio signals.
- Lidar determines distance with light.
- Laser altimeter measures elevation with lidar.
- Ranging instruments estimate the range either with one or two identical devices on different platforms sending signals to each other.
What are the different types of remote sensing?
There are two types of remote sensing technology, active and passive remote sensing. Active sensors emit energy in order to scan objects and areas whereupon a sensor then detects and measures the radiation that is reflected or backscattered from the target.
What is phytogeography and zoogeography?
The questions and approaches in phytogeography are largely shared with zoogeography, except zoogeography is concerned with animal distribution rather than plant distribution. The term phytogeography itself suggests a broad meaning.
What is static phytogeography?
STATIC PHYTOGEOGRAPHY is a study of plant dis- tribution at a given point in time. Dynamic or his- torical phytogeography takes into consideration the element of time, past as well as present ranges be- ing mapped, compared and analyzed.
What is geochemistry and its application?
Geochemistry is broadly concerned with the application of chemistry to virtually all aspects of geology. Inasmuch as the Earth is composed of the chemical elements, all geologic materials and most geologic processes can be regarded from a chemical point of view.
What does a biogeochemist do?
Biogeochemistry is a relatively new scientific discipline that explores the physical, chemical, biological, and geological processes and reactions that govern the composition of and changes to the natural environment.
