Spatial-Reference-Grid

The MajorTom spatial reference grid is now available as spatial data, provided in both GeoParquet and GeoPackage formats. It is a global grid containing 5,091,140 cells.

Field	Type	Description
grid_cell	string	Major TOM cell
grid_row_u	int	Major TOM cell row
grid_col_r	int	Major TOM cell col
utm_crs	string	CRS of the original product
centre_lat	float	Centre of the of the grid_cell latitude
centre_lon	float	Centre of the of the grid_cell longitude
utm_footprint	string	Polygon footprint (image UTM) of the grid_cell
geometry	geometry	Polygon footprint (WGS84) of the grid_cell
geotransform	array	geotransform of the footprint

Example Use

Interface scripts are available at

import geopandas as gpd

gdf_pq = gpd.read_parquet("MT_grid_10km_global.parquet")
gdf_pq.head(5)
