Global Point Cloud 2D Observation Data Visualization Tool（L2 SWIR）
- QGIS Plugin
The tool can display a time-series animation of column amounts for substances such as CO2 and CH4 as point cloud data. It also provides the graph of observed values for specific POI or AOI.
Features
Automatic color coding of GOSAT data to be used
When GOSAT data is downloaded and displayed on a map, it is all displayed in the same color by default in QGIS. Assigning appropriate colors for each scene according to your own observation values will make it easier to see, but it is time-consuming to set up each piece of data individually. This tool enables you to color-code your data in batches.
Graphical display of GOSAT time-series data
GOSAT's observed column data for CO2, CH4, water vapor, and other gases can be imported as point cloud data, allowing you to track changes over time.
By displaying data for several years in a time series, you can prepare the graph of long-term changes of column amounts. Specifying a POI or an AOI you can display time-series graphs for the selected location.
Animated display of images in chronological order
Column amount data from multiple selected point clouds can be replayed as an animation on a QGIS map. This enables you to visually grasp the time-series changes in the observed values.
Getting started
QGIS Installation Required
QGIS installation and setup is required. Please refer to the manual for preparation instructions.

Sample projects
For those who are unsure of how to search for and download data, we have prepared a sample project with data previously narrowed down by time period and data interval.
* The sample project is created using data as of March 2025. It may not include the latest data.
