IsWhere Image and Videos - Under Deveopment


Geotagging Imagery and Video

IsWHERE is a log of my thoughts, reflections, and news/blog links on the emergence of image and video geospatial tagging. On May5th this year, I opened a second blog to deal with more detailed aspects of tools for FalconView and TalonView can be found at RouteScout. Trends I want to try and follow are the various disruptions resulting from spatial smart-phones, how many GPS devices are out there, smart-cameras, and other related news. And yes, I have a business interest in all of this. My company Red Hen has been pioneering this sort of geomedia for more than a decade.

So beyond a personal blog, I also provide a link to IsWHERE a shareware tool created by Red Hen Systems to readily place geoJPEG or geotagged imagery and soon GEM full motion media kept on your own computer(s) into Google Earth/Map from your File Manager media selection. Works great for geotagged images from Nikon, Ricoh, Sony, iPHONE, Android and all geo-smartphones that can create geotagged images. IsWhere - read about it

High-sensitivity, high-speed, high-ac...

Free Geography Tools

  1. High-sensitivity, high-speed, high-accuracy GPS chipset.
  2. A high-gain, omni-directional antenna. Many units these days come with just a small ceramic patch antenna, and tend to have less signal gain and be more orientation-sensitive than the “stubby” quad-helix antennas found on models like the Garmin 60CSx and the Garmin Colorado series.
  3. A decent-sized screen that’s easily visible in direct sunlight. 2.6” diagonal is a bare minimum, 3” is even better. Many recent models have higher resolutions and greater color depth than older models, but sacrifice daylight visibility as a result. I’d rather have a unit with fewer colors and lower resolution that you could use in daylight than a sexy high-tech screen where you can’t see anything on it unless you hold it in the shade with the backlight on.
  4. An easy interface for adding text. If it doesn’t detract from screen visibility, a touch screen is fine, but a slide-out keyboard would work as well.
  5. Buttons with programmable functions. One of the big problems with touch screens is that you sometimes have to dive multiple menu levels into the interface to access a needed function; the ability to call up such a function with a single button push would make life a lot easier.
  6. Decent battery life, at least 15-20 hours.
  7. Rugged and waterproof.
  8. More waypoints, tracks and trackpoints. Some models currently sold allow only 1000 waypoints, and 10,000 trackpoints, to be saved. I’ve never had to have more than several hundred waypoints myself, but I’ve hit my unit’s limit of 20 tracks and 10,000 waypoints many times.
  9. The ability to add your own GIS map data, like point/line/area shapefiles, for display on the unit, preferably with at least some attribute data.
  10. Loadable vector maps, from the manufacturer and/or custom maps created by the user or others.
  11. Raster imagery like topographic maps or aerial imagery, both standard mapsets (like USGS topos) and your own custom imagery.
  12. A tri-axial electronic compass that works regardless of how you hold the GPS.
  13. If you have a tri-axial compass, you have the electronics necessary to determine the angle of orientation of the GPS with respect to the ground. This would be useful for geologists (dip and strike), archaeologists (site maps), geomorphologists (ground slopes), botanists (calculations of tree height using angle), and presumably others as well.
  14. Some means for recording additional data associated with a waypoint. Standard waypoints are limited to about 30 characters in the note field, and expanding that to a larger size to add more info would be helpful; another option would be audio recording capability that’s linked to the waypoing.
  15. A built-in camera with both automatic geotagging, and automatic tagging of the direction the picture was taken in. 5-megapixel minimum, with autofocus and a macro mode for closeups.
  16. Bluetooth NMEA serial output so you can use it with a laptop or PDA.
