Hi all,
During the past few days I was playing around with the code to do a test implementation for GIS data visualization. Now I have pushed it to my repo and I would like to hear you comments about it. You can check it out at [1].
Currently it does the following
- 'Visualize GIS data' link is displayed in 'Query results options'
pane ONLY for query results that has atleast one geometric column. 2. If there are more than one geometric columns in the results, the user can chose which column to be used for th visualization 3. You chose out of non-geometric columns a label column, which is used for tooltips. 4. Also, try zooming and panning.
I created a database with geometric data (database: opengis), so it would be easy for you to test the above. In case database server has reset by the time you login and you can't find the database, I have also attached the sql file here.
Madhura, no file was attached but I suggest opening a patch artifact and attaching your file there.
Ooops!! I opened a patch artifact and attached the sql file there. You can find it at [1]
One problem I encountered during the implementation is that flot does not support drawing polygons with voids inside them. I had to draw another polygon with its fill color set to background color in order to pretend the void and i'm not vary happy with that :( However reading the SVG specification I didn't find it to support polygons with voids either [1]. I'm wondering what to do about that.
What do you mean by "polygons with voids"? It you mean that you need a polygon's outline, use <polyline> with the first point repeated at the end, this should do the trick.
