All about ERS Files

The ERS file type is primarily associated with ERDAS IMAGINE.

ERS	File extension: ERS
	File type:	geospatial raster metadata file

What is an ERS file

ERS files mostly belong to ERDAS IMAGINE. ERS files exist in more than one use case. In one case, they are ER Mapper raster files used in geospatial applications. These files store raster metadata such as coordinate systems, projection data, and spatial resolution. They usually accompany larger imagery files and are processed with software like ERDAS IMAGINE.
In another case, some ERS files are used as French e-mail timestamp files. This format records the timing details of an email, as seen in systems provided by La Poste - Chronopost (also labeled as Horoquartz ERS TimeStamp).
Key details provided by FilExt.com include:

They do not hold the actual image or email content but rather the metadata.

For geospatial ERS files, use specialized GIS software.

For timestamp versions, refer to the appropriate email system or vendor.

FilExt.com tip: For additional info on geospatial files, visit Hexagon Geospatial and for French timestamp files check Chronopost.

How to open an ERS file

You need a suitable software like ERDAS IMAGINE to open an ERS file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your ERS file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a ERS file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert ERS files:

ERDAS IMAGINE
See the previous paragraphs to learn more about the main application. ERS files are often referred to as ERDAS IMAGINE gis because this type of file is primarily created or used by this software.
EARS Control File
EARS = UK Liberal Democrats Election Agents Record System - The file name starts with the letter E.
Earth Resource Mapping Satellite Image Header
The identifying characters used for this association are - Hex: 44 61 74 61 73 65 74 48 65 61 64 65 72 20 42 65 67 69 6E, ASCII: DatasetHeader Begin.
Eraser
(file deletion ["shredding"] program)
Pro/ENGINEER (Temporary File) by PTC
Pro/ENGINEER is a 3D product design product, featuring productivity tools that promote best practices in design while ensuring compliance with your industry and company standards. These files appear and disappear at various times when using Pro/ENGINEER. They are part of what PTC collectively calls "turd" files and the display of them in the program can be turned off in the options.

ERS file format:

Every file has a defined file format, i.e. how the data is arranged in the file. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. However, different programs can use the same file extension, and file extensions can be assigned incorrectly. So a detailed analysis of a file is vital in order to determine the format and the associated program. Below is our analysis of the ERS files:

The ERS file extension is rarely used and is used by different programs with different formats. The file formats most commonly found in ERS files are:

65% of all ERS files are Earth Resource Mapping Raster files. The contents of these files can even be read by a human. The average file size is 870 bytes with most files being between 640 bytes and 1 KB in size. The file type was developed 10 years ago and is still in use today. Certain words are almost always found in the files, such as DatasetHeader Begin, Version, Name, DataSetType, LastUpdated, DataType, = Raster, ByteOrder, CoordinateSpace, = "6.0", = ERStorage, DataFile and = LSBFirst. Such ERS files store data about topo.

All the rest of the ERS files (35%) have different formats. They are often associated with spec. Drag & drop your file here to see the file format and a preview of your ERS file!

an ers geospatial raster metadata file is a special file format and should only be edited and saved with the appropriate software.

How to solve problems with ERS files

Associate the ERS file extension with the correct application.
Update your software that should actually open geospatial raster metadata files. Because only the current version supports the latest ERS file format. Search, therefore, e.g. on the manufacturer website after an available ERDAS IMAGINE update.
To make sure that your ERS file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
