In this article we will discuss
how to create a layer
of points with ArcMap containing positions and links to » geotagged «
Geotagging is to specify the geographic coordinates photos
(or tags) EXIF . EXIF
(Exchangeable Image file format) of a photo includes information
such as the camera type, date and time of shooting etc …
If you have a camera for shooting
with a GPS, the location data can be

procedure in ArcMap is extremely simple.
1- copy your images in a directory .
Using Windows Photo Viewer , for example , make sure
the photos are oriented correctly
. Since you are going to link
the images to the created layer, the images will be viewed
with ArcMap. Therefore, it is essential that
they are stored at the right place .
2-Open ArcMap and the Toolbox window. Launch
tool GeoTagged photos
3-Set the tool .
It is possible to create an
output layer in shapefile, but
the link to the images. You will only
have the position of these. Therefore, opt by a
subclass as an entity of a file geodatabase .
tool . The result appears in the cartographic window
You can change the images points symbology
to indicate the position of the photo.
In effect , if we display the
attribute table of the new layer created one observes a field
To position the symbol according
to the direction of each image: open the properties layer -> tab
Click Advanced -> Rotate and select
the Direction field and the option Geographical
Now, the symbols show
orientation of the shooting on the ground.
To view an image from the corresponding
symbol in the map you can :
In the window that opens the lit up symbols allow
image linked to the corresponding point .
- use the HTML
The image is interpreted
of the point information and is displayed automatically
