LEET CARBON Provides High-Resolution Data of Land Cover for all Purposes

To celebrate the launch of our platform, we provide free access to 10-m resolution data of Land Cover and Land Use for the entire Bangkok Metropolitan Region between 2015 and 2021.

Data Overview

LEET Carbon employs Machine Learning and Deep Learning algorithms to generate data of land cover and land use changes in Thailand and beyond. LEET Carbon can also detect and monitor the individual trees.

LEET Carbon uses the LEET cloud computing platform and Google Earth Engine earth observation satellite data. These datasets can be used for education and research purposes to support the development of various urban programs, natural resources management, and Reducing Emissions from Deforestation and Forest Degradation (REDD+) and Land Use, Land-Use Change and Forestry (LULUCF).

Data Classification

    The land cover data is derived from the recently developed phenology-based threshold classification (PBTC) method (Venkatappa et al., 2019) in the LEET Carbon cloud computing platform. The PBTC method was used to detect and map the land cover categories available at 10-meter resolution European Space Agency Sentinel-2 MSI: MultiSpectral Instrument, Level-1C satellite imagery from 2015 to 2021. The detailed methodology of PBTC is explained in our publication Venkatappa et al. (2019) and Venkatappa et al.(2020).

Data coverage

    In Version I, the free data coverage is only for the Bangkok Metropolitan Region, Thailand including 6 provinces and 78 districts from 2015 to 2021. The data provided here only cover the urban region within the radius of 10 meters around settlements or built-up areas. To improve the land cover accuracy, we created urban boundaries using Sentinel 2 imagery in 2020 and keep this boundary as a base boundary for assessing the land cover changes for all the years between 2015 to 2021. We did not consider areas for classification where there is no built-up or settlements area. Based on this land use and land cover data, Version II of the LEET Carbon will use 4.77-meter resolution of the Planet & NICFI Basemaps for entire Southeast Asia for LULC mapping and Sentinel-1 SAR GRD: C-band Synthetic Aperture Radar Ground Range Detected data for land use land cover change detection.

    1: Water: inland and seawater

    2: Urban/built-up lands: Residential land, industrial land, quarries, pits and mines, commercial land, land used by public services, land of mixed-use, land used for transport, recreational, and other open lands.

    3: Croplands: Cultivation of crops, agricultural lands, and grass areas.

    4: Forest: Tree cover

Data Displaying and Utilization

Download raw data files. To visualiz the land use land cover data by district or province, please use Microsoft Excel or any relevant software that supports reading the CSV files. High-Resolution land use and land cover data has a GeoTIFF format. You can use remote sensing image processing software, ArcMap, QGIS, or any other software that supports visualizing and manipulating the GeoTIFF files. Please note that the software introduced here is only an example, and the functionality is not necessarily guaranteed by LEET Carbon. Please understand that LEET Carbon cannot answer any questions about image processing software.
