Hi all, I have pushed into my repo, the code for visualizing GIS data. I used
SVG
for this purpose and i'm writing the SVG tags accordingly. This allows
the
users without JS support also to view the visualizing oppose to using
jQuery
SVG to generate SVGs. Further it allows the SVGs to be saved, which is
one
of the upcoming features. However I use jQuery SVG to manipulate the
SVGs
(zoom and pan), so the users with JS support gets a better user
experience.
I have also integrated two small libraries [1],[2] to allow panning the
SVG
on dragging and zooming on mouse wheel movement. These are not strictly needed but nice to have ones. One problem of SVG is the IE versions <=8 does not support is. I am
using
the GD library to generate a PNG image for them and this is in line with saving those visualization to various formats. You can test this out at my demo server[3] using the data in the opengis table. Please be kind enough to share your comments.
Hi Tyron,
Thank you for your time.
2 things I noticed:
- When zooming it doesn't zoom relative to the cursor position
Yes, I think this should be addressed. I'm looking into it.
Fixed. Should be able to see when the demo server updates.
- I couldn't use any of the form fields below - the svg area was always in
focus
What do you mean by 'form fields below'? You mean the links referring to the GIT version and all(bottom right)? Yes, that link does not seems to work. But the link in the advertisement on bottom left is working. Wonder how that happens.
I'm using Chrome under Windows XP.
