What is an IGR file?

File extensions play a crucial role in identifying and categorizing various types of files. One such file extension that may not be widely known but has its significance is the ‘.IGR’ file extension.

In this comprehensive guide, we will delve into the world of ‘.IGR’ files, exploring their origin, history, file structure, technical specifications, advantages, disadvantages, and how to convert and open them on various operating systems.

More Information.

The history of ‘.IGR’ files can be traced back to the development of Intergraph’s Geomedia software. Geomedia was initially released in the late 1990s and has since become a vital tool in various industries, including urban planning, environmental management, transportation, and natural resource exploration.

The initial purpose of ‘.IGR’ files was to serve as a container for geographic data in a format that could be easily managed and analyzed within Geomedia.

These files were designed to store a wide range of geospatial information, including vector data, attribute data, symbology, and metadata.

Over the years, ‘.IGR’ files have become a standard format for storing and exchanging geospatial data among GIS professionals and organizations.

Origin Of This File.

The ‘.IGR’ file extension is closely associated with the world of geographical information systems (GIS) and spatial data analysis.

These files are primarily used in the realm of cartography, geography, and geospatial sciences. IGR stands for “Intergraph Geomedia Region,” and these files are generated by Intergraph’s Geomedia software, a powerful GIS tool used for mapping, geospatial analysis, and data visualization.

Intergraph, now a part of Hexagon AB, has a long history of developing geospatial software solutions, and Geomedia is one of their flagship products.

‘.IGR’ files are generated within Geomedia and contain critical spatial data used for mapping and analysis purposes.

File Structure Technical Specification.

Understanding the internal structure and technical specifications of ‘.IGR’ files is essential for anyone working with geospatial data.

‘.IGR’ files are binary files, which means they contain data in a format that is not easily human-readable. The structure of an ‘.IGR’ file consists of various sections, each dedicated to specific types of information.

Header: The header section of an ‘.IGR’ file contains essential metadata, such as the file version, creation date, and information about the coordinate system used.
Geometry Data: This section stores the geometric information, such as points, lines, and polygons, that define the spatial features within the file. These geometries are represented using a variety of algorithms and data structures optimized for GIS applications.
Attribute Data: ‘.IGR’ files also contain attribute data associated with the spatial features. This data includes information like names, values, and descriptions for geographic elements, making it possible to perform attribute-based queries and analysis.
Symbology Information: To maintain consistency in visual representation, ‘.IGR’ files include symbology information, specifying how spatial features should be displayed when visualized on a map. This information includes attributes like colors, line styles, and symbols.
Indexing and Metadata: To enhance query performance and provide additional information about the data, ‘.IGR’ files may include indexing structures and metadata sections.

How to Convert the File?

Converting ‘.IGR’ files to other more widely supported formats can be necessary to ensure compatibility with various GIS software packages. Here are steps to convert ‘.IGR’ files:

Use Geomedia: If you have access to Intergraph’s Geomedia software, you can open the ‘.IGR’ file and export it to a different format, such as Shapefile (.SHP) or GeoJSON (.geojson).
Third-party Conversion Tools: Several third-party conversion tools are available that can convert ‘.IGR’ files to other formats. These tools may offer batch conversion capabilities and can be more accessible to users who do not have Geomedia licenses.
GIS Software: Many GIS software packages, such as ArcGIS and QGIS, can import ‘.IGR’ files directly and allow you to export them in alternative formats. This method is ideal if you are planning to work with the data in another GIS system.

Advantages And Disadvantages.

Advantages:

Comprehensive Geospatial Data: ‘.IGR’ files can store a wide range of geospatial data, making them suitable for complex GIS projects.
Interoperability: Many GIS software packages can read and write ‘.IGR’ files, making it easier to exchange geospatial data between different systems.
Efficient Storage: The binary format of ‘.IGR’ files allows for efficient storage of spatial data, minimizing file size while preserving data integrity.

Disadvantages:

Proprietary Format: ‘.IGR’ files are tied to Intergraph’s Geomedia software, which means users may encounter compatibility issues when working with other GIS software.
Limited Accessibility: Geomedia is not as widely used as some other GIS software, so not all GIS professionals may have access to tools that can work with ‘.IGR’ files.
Complex Structure: The binary nature and complex structure of ‘.IGR’ files can make them challenging to work with directly, especially for those unfamiliar with the format.

How to Open IGR?
Open In Windows
If you have Intergraph’s Geomedia software installed, simply double-click the ‘.IGR’ file, and it should open within the application.
Alternatively, you can install other GIS software like ArcGIS for Windows or use QGIS, an open-source GIS platform. Open the software and use the import function to open the ‘.IGR’ file.

Open In Linux
Linux users can also use QGIS, which is available for most Linux distributions. Install QGIS, open it, navigate to ‘Layer’ in the menu, and choose ‘Add Layer.’ Select the ‘.IGR’ file you want to open.

Open In MAC
MacOS users can follow the same procedure as Linux users. Install QGIS for macOS, open the software, and add the ‘.IGR’ file using the ‘Add Layer’ option.

Open In Android
Android devices do not typically support ‘.IGR’ files natively. However, you can use third-party apps that support geospatial data formats like GeoJSON or KML. Apps like ‘Mappt’ or ‘Locus Map’ allow you to import and view geospatial data on Android.

Open In IOS
Like Android, iOS does not natively support ‘.IGR’ files. Consider using apps like ‘Mappt’ for iOS or ‘Maps 3D PRO’ that support geospatial data formats for viewing and analysis on your iOS device.
