Introduction
The natural resources signifying available land, water and
forest have been serving the mankind by providing valuable
services like food items, fuel and fodder, important medicines,
regulating the air and water currents, protecting the soil and its
components etc. FAO [1]. Moreover still the rural livelihood in
every country is dependent on these natural resources and its
condition for their sustainability and livelihood World Bank [2].
The major factors like population growth agriculture expansion
and increased human well-being have been at the cost of forest
depletion. The exponential increase in human population from
seven billion to nine billion in the coming years has increased
pressure on natural resources which are depleting at a faster
rate than expected Millennium Ecosystem Assessment [3].
Further, the analysis of Ivanova et al. [4] has confirmed that
some of the ecosystem services are at stake. We may soon face
water scarcity, flooding of cities (because of degradation of
wetlands) and increase in temperatures (because of overgrazing
and overexploitation of forest trees).
Sustainable use of the natural resources would prevent
further loss. As defined by Norwegian Ministry for the
Environment [5] Sustainability means “the use of services and
related products which respond to essential needs and ensure a
better quality of life while minimizing the utilization of natural
resources and toxic materials as well as control the emissions of
waste and pollutants over the life-cycle so as not to jeopardize/
threaten the needs of future generations”. Thus, a detailed
management plan for the natural resource is needed which would
identify clear objectives, evaluate existing natural resources and
its uses to develop long term plans. To achieve this, a reliable
geo-information database is required to prepare action plans
for sustainable development at micro level. Natural resources
assessment can be made using these parameters which would
help the forest managers in multiple ways Hudak et al. [6]. These
days satellite remote sensing data like LANDSAT, LiDAR etc are
available for free download, which open up the opportunity for
many researchers, government authority, and stakeholders for
creation of data base on natural resources Kennaway et al. [7].

Abstract
The evaluation of the natural resource plays a decisive role in management and sustainable developmental planning. The study aims
to generate natural resource based maps of rural areas of the USA using remote sensing datasets such as Landsat and LiDAR to analyze
generated natural resources for developing digital elevation (DEM) and canopy height models (CHMs). Natural resource maps were generated
using Landsat image of the year 2010. The area statistics reveal that the tree class percent (23.21 %) was the second highest after fallow land
class (60.44 %) whereas shrubs and grass/agriculture was 6.59 % and 6.47 %, respectively. Later, LiDAR datasets for the same time were
used to generate DEM/surface models (DSM) and CHMs. Spatial analysis was done to attempt hypothetical queries pertaining to resource
management. Further, all the generated datasets from different sources including slope map, drainage map etc can be integrated in GIS
domain for effective decision making. Coarse resolution Landsat data can be effectively used to monitor natural resources up to micro level if
used skillfully in conjugation with rectified images. LiDAR datasets have huge potential to generate highly accurate DEM, DSM and CHMs. Such
accurate data will be informative for qualitative and quantitative assessment of various natural resources.
