Earth Observation Satellite Track and Global MGRS/Geographic Tile Visualization Tool¶

by Earth Big Data LLC

          Last updated: 2024-11-11 09:08 UTC

Overview¶

The tool below enables visualization and identification of several Earth observation satellite mission ground tracks and their location with respect to two common data tiling frameworks: The Military Grid Reference (MGRS) tiling system adopted for Sentinel-2 and the Harmonized Landsat/Sentinel-2 project, and the geographic 1x1 degree tiling over land areas. The tool enables identification of tile boundaries and satellite tracks covering any given tile. For the geographic 1x1 degreee tiles a lower left (LLName) name (e.g. used by SRTM, NASADEM) or upper left (ULName) name (e.g. used by JAXA for ALOS ScanSAR data) is provided. We also share a status map of Analysis Ready Data (ARD) in form of MGRS-tiled time series stacks of Sentinel-1 data processed by and available from Earth Big Data LLC.

Supported Satellite Missions¶

Currently supported Satellite Missions (with open data policy):

  • Landsat World Reference System 2
  • Sentinel-2 Tracks (Download)
  • Sentinel-1 Ascending and Descending Observation Scenarios (Detailed KML Files)
  • NISAR Track/Frame location for ascending and descending paths (with actual recent acquisition dates once the mission launches)

Interaction with the Visualization Tool¶

  • Turning on/off grids and satellite track data: Click on labels in the legend
  • Turning on/off detailed information on a location: Cick on Hover tools in the toolbar (Sequence from top to bottom is same as in the legend)
  • ZOOM IN with Box Selection tool (enabled by default)
  • ZOOM OUT with Reset tool
  • ZOOM IN/OUT with Wheel Zoom tool (only recommended at zoomed in levels after using box selection)
  • Pan with the Pan tool.

Note: An active tool is marked with a blue vertical line to the left of the tool. When zooming or paning please allow for a couple of seconds for the plot to update occasionally.

Questions and Suggestions¶

Please send questions suggestions on the tool, to contribute satellite tracks from other missions, or on ARD data access to info@earthbigdata.com.
