Photographers Have Several Camera Options for Geotagging Pictures with GPS Points

Der er mange måder at geo-tagge på ...

Snag it, bag it, tag it ...


From the weekend camera buff to the sophisticated GIS user, 'geotagging' photos with location coordinates has become a popular application of GPS technology. Geotagging, which adds coordinates to a digital image so that it can be accurately placed on a digital map, has spawned a new market we call photo mapping that has compelled the manufacturers of digital cameras, cell phones and GPS receivers to develop a variety of products designed to make it easier to stamp images with GPS points.

In just the past two years, some of the biggest names in cameras - Ricoh, Nikon and Canon - have released models that either have GPS built into the camera body or are designed for direct inputs from an external GPS device. Never wanting to turn their backs on a potential new app, cell phone developers have gotten in on the photo mapping action by integrating cameras and GPS chips inside the phones for automatic geotagging of pictures. And GPS equipment developers like Trimble are approaching the market from the opposite direction by adding cameras to their newest receivers. GPS digital cameras are popping up everywhere.

At GeoSpatial Experts, we introduced GPS-Photo Link in 2001 as the first software developed specifically for mapping photos. At the time, our software was geared almost exclusively toward professionals who needed to document their photos in a GIS. Over the past few years, however, the photo mapping market has expanded dramatically as camera, GPS and Web-based mapping technologies have evolved and become increasingly intertwined.

Today, we see three distinct groups of end users comprising the market for photo mapping technology: GIS professionals, non-GIS business professionals and recreational photographers. The application needs of these groups are so different that we ultimately created two versions of GPS-Photo Link to serve the GIS and non-GIS professionals.

The purpose of this article is to differentiate these three user groups, and match their needs with the latest GPS digital camera offerings. Ideally, this information will help readers select the photo mapping hardware that best fits their budget and meets the needs of their applications. [...]
