RAW with geotagging

Geotagging RAW files without loosing image quality

RAW files are unprocessed image files that contain raw sensor data captured by a digital camera. These files are known for their high-quality and flexibility in post-processing. When combined with geotagging, RAW files can be enhanced with accurate geolocation metadata, such as latitude and longitude coordinates. Geotagging RAW files provides valuable context and enables photographers to document the exact location where the photo was taken. It enhances organization, storytelling, and makes it easier to search and discover images based on location. Geotagging RAW files is particularly useful for travel photography, outdoor adventures, scientific research, and any projects that require precise location data.

Understanding RAW with geotagging

Geotagging has become an essential feature of high-quality digital photography. While geotagging is commonly associated with JPEG or other compressed image formats, it is also possible to geotag the RAW image format. The geotagged RAW format preserves high-quality original data while embedding geotagging metadata into the photo.

RAW image formats

RAW image formats refers to unprocessed files that record all data captured by the camera sensor. Unlike compressed formats like JPEG, RAW files retain the original sensor data, making post-processing more flexible. The RAW format varies between camera manufacturers, including popular formats like CR2 (Canon), NEF (Nikon), ARW (Sony), and DNG (Adobe Digital Negative).


Geotagging involves associating precise geographic information, such as latitude and longitude coordinates, with digital images.

Importance of geotagging RAW image formats

RAW geotagging has significant importance due to its ability to preserve location metadata while maintaining the integrity of the image data. RAW files, known for their uncompressed and unprocessed nature, offer a wealth of information and flexibility to photographers.

Benefits and applications of geotagging RAW image formats

Geotagging RAW image formats offers many benefits and opens up various applications, including
  • Location documentation and reference: Geotagging allows photographers to accurately record the geographic coordinates of every photo taken in RAW format. This information serves as valuable documentation and reference for future use, research, or customer needs.
  • Efficient workflow and image organization: Geotagged RAWs streamlines post-processing, such as automatically sorting and classifying images based on location, making them easy to find, retrieve, and manage large photo collections.
  • Enhanced localization context: Geotagged RAWs provide a better understanding of the captured scenes. Precise geolocation data adds context and enhances the narrative aspect of images, making them more engaging and impactful.
  • Geoanalysis and research: Geotagged RAWs are a valuable resource for geographic analysis and research to study environmental changes, analyze spatial patterns, track dynamic wildlife populations, and conduct a variety of studies related to geography and the environment.
  • Travel and discovery documents: Geotagged RAW is especially useful for travel photographers to create detailed travel logs, map their trips, and share their experiences with exact location information. Geotagged RAW images provide a rich visual representation of the places visited.
  • Mapping and collaboration initiatives: Geotagged RAW can be shared and used for collaborative projects or mapping initiatives. By aggregating geotagged images, photographers and enthusiasts can create comprehensive visual databases, contribute to mapping efforts, or collaborate on location-specific projects.
  • Fine art and exposure: Geotagged RAWs offers artistic possibilities, especially in fine art photography. Incorporating geolocation data into art narratives allows photographers to explore the relationship between art and geography, creating thought-provoking exhibits that highlight the connection between art and geography.

Methods and recommendations

Geotagging methods for RAWs
  • Camera GPS: Some high-end cameras have a built-in GPS receiver that automatically collects geolocation data at the time the photo is taken. This eliminates the need for additional geotagging steps.
  • External GPS device: External GPS devices, such as GPS trackers or smartphone apps, record precise location information during shooting. They can then synchronize this data with the RAW images during geotagging.
  • Geotagging software: Various geotagging software tools are available that allow manually adding geolocation data to RAWs. These tools often provide a user-friendly interface for entering accurate coordinates or importing GPS track logs.

Recommendations for geotagging RAWs
  • Ensuring accurate geolocation data: Use a reliable GPS device or a smartphone app with precise positioning to record precise latitude and longitude coordinates.
  • Time synchronization: Ensure that the time settings of the camera and GPS device are synchronized to accurately match the geotagging data with the corresponding RAW image.
  • Metadata standardization: Follow established metadata formats and conventions for geolocation data in RAW files. Following the guidelines and standard tags ensures compatibility and interoperability between different software and platforms.
  • Backup and preservation: Make sure to back up your geotagged RAW files and preserve the integrity of the embedded geolocation metadata to maintain the accuracy of the location information for a long time.

Privacy and considerations

When geotagging RAW, it is essential to consider privacy concerns, especially when sharing images online. Be careful when disclosing personal information or sensitive location information. Check your privacy settings and consider adjusting or removing geolocation metadata as needed.


Geotagging RAWs offers a powerful tool to enhance geolocation data and expand the working possibilities. Document locations, streamline the workflow, provide enhanced context, and support geographic analysis and research by geotagging RAWs. It is important to follow recommendations, use reliable GPS equipment, and preserve metadata to ensure accurate and reliable geotagging. The adoption of geotagging in the RAW image format opens up new opportunities to showcase portfolios, work on location-based projects, collaborate with others, and explore the intersection of photography and geography.
