Why is LULC important?

Overview. Land Use Land Cover (LULC) maps of an area provide information to help users to understand the current landscape.

We estimate that humans have modified >50% of Earth’s land surface. The current rate of land transformation, particularly of agricultural land, is unsustainable.

Why are LULC maps necessary in geography?

This requires the present and past land use/land cover information of the area. LULC maps also help us to study the changes that are happening in our ecosystem and environment.

What are the global land cover datasets?

Global Land Cover Datasets. This page offers access to a number of datasets which describe land cover characteristics at 1°×1° resolution and to some sample data product images. The datasets were assembled by Inez Fung, Elaine Matthews, and associates during 1984-1991. The land cover datasets use a common format throughout,…

What is the purpose of the 2000 land cover database?

The general objective is to provide for the year 2000 a harmonized land cover database over the whole globe. The year Two Thousand is considered as a reference year for environmental assessment in relation to various activities, in particular the United Nation’s Ecosystem-related International Conventions.

Who created the 1°×1° land cover dataset?

This page offers access to a number of datasets which describe land cover characteristics at 1°×1° resolution and to some sample data product images. The datasets were assembled by Inez Fung, Elaine Matthews, and associates during 1984-1991.

What does the glc2000 V1 classification reveal about the European continent?

Quality checks of the GLC2000 v1 classification for the European continent reveal large discrepencies when compared with existing high resolution European land cover databases.

What is land use and land cover in remote sensing?

Land cover especially implies the spatial distribution of the various classes of land cover that can be assessed both qualitatively as well as quantitatively through remote sensing techniques, while land use mainly focuses on human activities determined by the integration of natural and social scientific methods in …

What is land cover change detection?

Abstract. Land use land cover (LULC) change detection based on remote sensing data is an important source of information for various decision support systems. Information derived from land use and land cover change detection is important to land conservation, sustainable development, and management of water resources.

What are two types of land cover?

What is the difference between land use and land cover?

Identification of land cover establishes the baseline from which monitoring activities (change detection) can be performed, and provides the ground cover information for baseline thematic maps. Land use refers to the purpose the land serves, for example, recreation, wildlife habitat, or agriculture.

How is land use change calculated?

There are a lot of methods for land use change detection such as Image rationing, Image difference, Change vector analysis, Image regression, Composite analysis and Post-classification comparison. One of the most widely used change detection methods is post-classification comparison method.
