INTRODUCTION TECHNIQUES AND CRITERIA FOR EVALUATION OF REGIONAL LANDSCAPE RESOURCES
Landscape as a kilometer wide mosaic over which local ecosystems recur. This reflects the view that research and decisions often need to be based on a wider area than the immediate site or locality. Scale in this context refers to the spatial or temporal dimension of an object or process, characterized by both grain and extent – degree of resolution and the size of the geographical area in question.
Regional Scale: Comprises of Patterns that result from the underlying geology and landform overlaid with the influence of broad ecological associations and key aspects of settlement and enclosure history. This results in the identification of distinct landscape types and areas such as mountain, plateau, plains. 3

TERMINOLOGIES TECHNIQUES AND CRITERIA FOR EVALUATION OF REGIONAL LANDSCAPE RESOURCES
Landscape has been subdivided into following classes (Fochler-Hauke 1959): • Landscape Morphology considering the form and spatial structure of phenomena • Landscape Ecology concerned with functional interrelationships • Landscape Chronology concerned with development of regions over time Regional landscape is managed for a range of functions and values, including agriculture, water quality, nature conservation, scenic amenity, ecosystem services, heritage and outdoor recreation. Regional Landscape Mapping Regional mapping depends on the size of the region (county, metropolitan region, state or more). Following maps are required for Landscape Assessments: • Base - jurisdictions, roads, cities/towns, protected lands, streams, rivers, lakes and other waters, urbanized "footprint", and topography • Natural factors - soils, rivers/streams by classification, elevation levels • Biodiversity - vegetation, habitat classifications, key corridors and linkages for animal migration, threatened and endangered species • Working landscape - farmland (crops), ranchland, timber zones, aquaculture/fisheries and other natural resource-based economic uses Source: G.T.

LANDSCAPE ASSESSMENT TECHNIQUES AND CRITERIA FOR EVALUATION OF REGIONAL LANDSCAPE RESOURCES
Landscape structure : The structure of a landscape is defined by the particular spatial pattern or heterogeneity of the landscape being represented, and it consists of two components: • Composition defined by the spatial elements that are distinguished in the map and believed to be relevant to the landscape function under consideration. Composition represents the non-spatial aspect of a landscape, since only number and abundance of landscape elements is considered, not their spatial configuration. •
Configuration defined by the spatial character, arrangement and context of the elements. Configuration represents the spatial aspect of a landscape.
Landscape function: The services that landscapes provide to humans are functions example: providing for • biological diversity, • recycling nutrients, • sequestering carbon, • producing clean water Landscape boundary and context: Landscapes do not exist in isolation. Landscapes are nested within larger landscapes, that are nested within larger landscapes, and so on. In other words, each landscape has a context or regional setting, regardless of scale and how they are defined. Source: K. McGarigal; What is a Landscape,USAmherst

SENSING
TECHNIQUES AND CRITERIA FOR EVALUATION OF REGIONAL LANDSCAPE RESOURCES
The diagram below shows the flow of data acquisition in remote sensing. Energy Source or Illumination (A) illuminates or provides electromagnetic energy to the target of interest Radiation and the Atmosphere (B) as the energy travels from its source to the target, it comes in contact and interacts with the atmosphere it passes through. This interaction may take place a second time as the energy travels from the target to the sensor. Interaction with the Target (C) once the energy makes its way to the target through the atmosphere, it interacts with the target depending on the properties of both the target and the radiation. Recording of Energy by the Sensor (D) after the energy has been scattered by, or emitted from the target, we require a sensor to collect and record the electromagnetic radiation Source: Ying, Tan Ying.

Sensor: A device that measures and records electromagnetic energy. 1. Passive sensors depend on an external source of energy, usually the sun. The most common passive sensor is the photographic camera. 2. Active sensors have their own source of energy, an example would be a radar gun. These sensors send out a signal and measure the amount reflected back. Active sensors are more controlled because they do not depend upon varying illumination conditions.

• Mapping Mapping constitutes an integral component of the process of managing land resources, and mapped information is the common product of analysis of remotely sensed data.
Planimetry Land surveying techniques accompanied by the use of a GPS can be used to meet high accuracy requirements, but limitations include cost effectiveness, and difficulties in attempting to map large, or remote areas. Defence applications typify the scope of planimetry applications - extracting transportation route information, building and facilities locations, urban infrastructure, and general land cover. Baseline thematic mapping / topographic mapping Multispectral imagery is excellent for providing ancillary land cover information, such as forest cover. Supplementing the optical data with the topographic relief and textural nuance inherent in radar imagery can create an extremely useful image composite product for interpretation.

CONCLUSION TECHNIQUES AND CRITERIA FOR EVALUATION OF REGIONAL LANDSCAPE RESOURCES
The capacity of remote sensing to identify and monitor land surfaces and environmental conditions has expanded greatly over the last few years and remotely sensed data will be an essential tool in natural resource management. matter Geographic information systems (GIS) and Remote sensing (RS) are now being developed and demonstrated suggest regional landscape resource applications that were not believed possible using traditional techniques. The speed and quality of analysis and synthesis of certain site will be increase. These tools also help us to significant advances in data acquisition technology and have rapid improvement in data storage, retrieval and analysis. GIS provides a powerful tool for managing information. Resource Management made a commitment to successfully develop a comprehensive GIS program. Without using GIS and RS, landscape resources will not be able to sustain in long period due to poor planning and management. Without these technologies, planners will need longer time to figure out the potential and constraint areas. Identification and listing of tangible and intangible elements of cultural, natural and historical values of regional landscapes will be highlighted and enhanced. Hence, protection and conservation of natural resources also can be carried out. Source: Author
