Hi,
I am new to the world of GIS and GeoTool. However I have the following question
in mind about the capabilities of the API and GIS.
1- As far as I understand, is that most GIS images, maps ... etc, all deal with
objects location (ie coordinates of the object with respect to longitude and
magnitude). So a raster image of the United States would contain an binary
data pictures of the US along with the location information associated with
these pictures. Is this true
2- As understood from the Image Lab tutorial is that I can add shape file into
to a raster image file. For example if I have a map image (Raster data) of the
USA, I can embed a
a shape file to it ,to for example, to specify universities and dorms since all
systems deal with the same location (Longitude, Latitude).
3- I still don't understand how zooming
and out are handled in GIS. This depends on the pictures (Amount of binary
digital data available, right?
4- Does geo tool provide a capability that if a clicked somewhere on the
displayed image, it will get to me the coordinate clicked, and then I can query
database to display certain information or maybe display a video.
It's a long list of question :)
Appreciate your answers and support,
