Identification of Land in Protected Forest Areas Using Landsat TM Image and Digital Elevation Model Analysis (DEM)

Introduction

The identification of land in protected forest areas is a crucial step in preserving the environment and ensuring the sustainability of forest ecosystems. In this study, we conducted a research on land identification and the appointment of protected forest areas in Aek Natas District and NA IX-X District, Labuhanbatu Regency, North Sumatra Province. The study aimed to identify the potential of protected forest areas and to analyze the topographic conditions and the possibility of the impact faced by the forest ecosystem.

Background

Protected forest areas are designated to conserve and protect the natural resources of the forest, including the biodiversity, soil, and water. The identification of land in protected forest areas is essential to ensure the sustainability of these resources. In recent years, the use of remote sensing technology, such as Landsat TM satellite imagery, has become a popular method for land identification and mapping. This technology provides a three-dimensional perspective (3D) of the land conditions, which is essential for understanding the topographic conditions and the possibility of the impact faced by the forest ecosystem.

Methodology

In this study, we used Landsat TM satellite imagery data taken in 2003 to gather information about land cover in protected forest areas. The data was analyzed using a Geographic Information System (GIS) to identify the potential of protected forest areas and to analyze the topographic conditions and the possibility of the impact faced by the forest ecosystem. The Digital Elevation Model (DEM) was used to provide a three-dimensional perspective (3D) of the land conditions.

Results

The results of this study showed that the potential of protected forest area in Aek Natas District reached 27,727,064 ha, while in the NA IX-X District area of 21,186,522 ha. The analysis of the DEM showed that the topographic conditions of the forest area were varied, with some areas prone to landslides or floods. The use of remote sensing technology, such as Landsat TM satellite imagery, also played a role in detecting changes in land cover from time to time.

Discussion

The identification of land in protected forest areas has a major implication of environmental sustainability and ecosystem protection. By using satellite image technology and DEM analysis, we not only get an overview of the area and location of protected forests, but also understand the topographic conditions and the possibility of the impact faced by the forest ecosystem. The data generated from this analysis can be an important tool for local governments and related parties in making decisions regarding forest management.

The use of remote sensing technology, such as Landsat TM satellite imagery, also plays a role in detecting changes in land cover from time to time. This is very important in the context of climate change and the influence of human activities that can threaten the existence of protected forest areas. Therefore, periodic monitoring is very important to maintain the integrity of forest areas and support the sustainability of natural resources.

Conclusion

In conclusion, land identification using Landsat TM imagery and DEM analysis is a crucial step in preserving protected forests in Aek Natas and NA IX-X, Labuhanbatu Regency. Through accurate and data-based mapping, we can develop more effective strategies in protecting the environment and ensuring the sustainability of the function of forest ecosystems for future generations.

Recommendations

Based on the results of this study, we recommend the following:

The local government and related parties should use the data generated from this analysis to make decisions regarding forest management.
The use of remote sensing technology, such as Landsat TM satellite imagery, should be continued to detect changes in land cover from time to time.
Periodic monitoring should be conducted to maintain the integrity of forest areas and support the sustainability of natural resources.

Limitations

This study has some limitations, including:

The use of Landsat TM satellite imagery data taken in 2003, which may not reflect the current land conditions.
The analysis of the DEM, which may not provide a complete picture of the topographic conditions of the forest area.

Future Research

Future research should focus on:

Updating the land cover data using more recent Landsat TM satellite imagery.
Analyzing the impact of human activities on the forest ecosystem.
Developing more effective strategies in protecting the environment and ensuring the sustainability of the function of forest ecosystems.
