Landsat File Naming Convention – Scene Identifiers

What is the naming convention for Landsat scene identifiers?

Have you at any point thought about what all the letters and numbers mean in a Landsat scene? It most likely resembles this – LC80390222013076EDC00.

But what does that mean?

In the wake of downloading a Landsat file from the USGS Earth Explorer, there’s shockingly a ton of data you can get from simply the document name.

Simply taking a gander at the naming show, you can get the satellite, sensor, area, date and that’s just the beginning. In this article, we clarify the naming show that Landsat employments.

LXS PPPRRR YYYYDDD GSIVV

A Landsat document can be isolated into squares of content. These squares stop for a minute, where, when, and how the satellite information was gathered.

The initial three letters give you data on what kind of satellite and sensor.

L = Landsat

X = Sensor

         C = OLI & TIRS

         O = OLI only

         T = IRS only

         E = ETM+

         T = TM

         M = MSS

S = Satellite

         8 = Landsat-8

         7 = Landsat-7

         5 = Landsat-5

         4 = Landsat-4

         3 = Landsat-3

         2 = Landsat-2

         1 = Landsat-1

LXS  PPPRRR  YYYYDDD GSIVV

The accompanying six letters disclose to you where the swath is on Earth. Landsat, in the same way as other different satellites, Uses the Worldwide Reference System (WRS) for indexing satellite information.

There is a WRS way which is the rising or slipping way. The WRS push sectionalizes WRS by rows.

PPP = WRS Path

 Ascending or descending path of the satellite

RRR = WRS Row

 The north-south line that sectionalizes WRS

LXS PPPRRR YYYYDDD GSIVV

These seven letters tell you when the swath was acquired using the Julian calendar. This means that you are essentially counting the number of days starting on January 1.

For example, a day like February 15 would have a Julian calendar value of 046. There are 31 days in January and add the total in February. (31+15=46)

YYYY = Year

 Year of acquisition

DDD = Julian day of the year

 The check of days from the beginning of the year

LXS PPPRRR YYYYDDD GSIVV

The last five letters in Landsat demonstrates how the information was gotten from one of its ground stations.

There is a global agreeable system of all dynamic ground stations worked by the US and International Cooperator (IC). Each ground station assumes a job for the downlink and dissemination of Landsat information.

GSI = Ground station identifier

 Data catch offices to get transmitted satellite data

VV = Archive version number

 Archive version number

Landsat Naming Convention Examples

These models separate a Landsat record utilizing indistinguishable strides from above.

LC8 039022 2013076 EDC00

 Landsat-8 OLI and TIRS

 WRS Path: 039; WRS Row: 022

 Date: March 17, 2013

 Receiving station and document number

LM1 017039 1976031 AAA01 (Landsat 1 MSS)

 Landsat-1 MSS

 WRS Path: 017; WRS Row: 039

 Date: January 31, 1976

 North American receiving station and archive number

Landsat File Names

You can intuitively gather valuable information simply from looking at the file name.

The Landsat file name structure gives you the what, where, when, and how the data was captured.

Test out your knowledge by downloading data from the USGS Earth Explorer.
