[Gvsig_english] Direct read integration of GPS-Photos

[Miguel Montesinos]

Hi Sebastian,

 

AFAIK, that feature it's not planned for future versions. There is a plan for generating geotagged photos in gvSIG Mobile, but not in the short term.

 

Nevertheless, I think it's a good extension, and I like your approach. Do you fancy to develop it? At gvSIG team we could provide you with help.

 

Regards,

Asunto: [Gvsig_english] Direct read integration of GPS-Photos

 

Hello Folks,

 

I'm new to this list. I work for a small company in the black forest. I use ArcGIS at work and qgis/grass on my ubuntu at home at the moment. I have an eye on the gvsig-project since the Intergeo in Leipzig :o)

Doing GIS and importing/selling special photo-GPS-units I came to inform you about the following:

 

A part of my work is about geotagged photos. Services like panoramino, locr, flickr,  picasa offer to show gps-photos on maps. People love it and geotagging is becoming a huge thing!

 

What I - and already some of my customers - are dreaming of, is to be able to import geotagged pictures into GIS! 

 

- Filtering pictures by location
- easy documentation of situations (fauna, flora, accidents, road damage, dagerous points, what ever)
- etc pp

 

There are allready solutions to bring pics into GIS, but most of them are anachronistic!

 

1.eVis for qgis

Does noit read EXIF-GPS-Information yet. That means you have pictures with coordinates etc inside but you have to build a shape table with that info by hand.

 

2. PhotoMapper for ArcGIS 

Reads EXIF-GPS-info. Writes path and name of the pics into a ESRI Geodatabase or Shapefile. Can show direction of photo in a map (heading). No direct read (That would be ESRIs job. PhotoMapper is 3rd party)

 

3. GlobalMapper

Direct read of EXIF-GPS in next release. No pathnames, etc in a shapefile, etc. Simply and quick. Simply shows a camera icon for each pic in the map. If heading is available an arrow is added to show the direction of the pic. A click on the icon opens a preview of the original. This basic function was Integrated in _one_ day!

 

4 . INTERGRAPH

I was asked for test pics to integrate functions

 

 

I could imagin the following:

 

1. leave the pictures as they are. The GIS just reads the EXIF header for lat/lon/elevation/heading, time, etc
2. Show a point icon in the map, if there is heading information show an arrow-like icon to indicate teh direction the picture was taken
3. A click on the icon opens the a thumbnail, aclick on the thumbnail opens the original pic from the harddrive
4. below the thumbnail the most important EXIF is shown (Time, name of pic, ...)
5.  Make picures points searchables/selectable like other points (distance search, ...)

then advanced:

 

6. Allow dragging the symbol to adjust the coordinates in the EXIF
7.  Add GPS info to pics without coordinates in the EXIF by shooting a point in the map and adding the lat/lon to the Exif
8. Allow to use empty EXIF fields to add user attributes

 

I think it is more easy and efficient to read directly the EXIF and treat the jpegs with GPS information as if the are a  regular GIS data type (As done with geoTIFF, etc. as well).
