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).
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
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
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
C-band Synthetic Aperture Radar Ground Range Detected data for land use land cover change detection.

2. Graph data: TIFF format.
3. Spatial data: Geographical reference system: WGS84
Land Cover and Land Use Class
The value of each land cover classification class ID number is as follows:
0: Others: This class includes, clouds, shadows, and non-urban or built-up land areas
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.
Frequently Asked Questions
Frequently Asked Questions to the LEET Carbon High-Resolution Data of Land Cover and Land Use
How can I get the free High-Resolution Data of Land Cover and Land Use?
Please fill your information in the subscription form to get the free land cover and land use data. Once you submit the form, LEET Carbon will send you the data access link to your email.
I cannot download the datasets
Please use the following recommended browsers: Google Chrome, Mozilla Firefox, Microsoft Edge, Apple Safari. Use of the desktop is recommended for quick access the data.
Can I get data by country, province, or district level by year?
Yes, please fill out the contact us form and specify your area of interest.
How can I know the data processing months of land cover and land use data?
For free data in the Bangkok Metropolitan Region, we specify the date range from January to May of the year.
How can I display the data?
Please refer to the Data Display
Can you provide data of forest carbon stocks and emission?
Yes, please contact us with your enquiry
Is the same classification method used for the land cover and land use
Yes. Basically, all of the land cover and land use maps are created by the same phenology-based thresholding method. These threshold values are modified according to the location and climatic condition and time. For details of the method, please refer to publication. Venkatappa et al. (2019) Venkatappa et al. (2020)
The Land cover and land use maps contains four numbers (from 0 to 3). What is the
meaning of these numbers?
