[GRASS-user] chamelon-GRASS application site with URL

Cannata_Massimiliano · September 1, 2006, 1:41pm

Hi all,
I would like to inform you that a demo site is now on-line to see how
GRASS is run trough Chameleon.
For instruction on how to use it, you can click the Help button.

The URL is: http://195.176.186.207:8002/chameleon/envca/

Could you try to check if everything is working and eventually give me a
feedback?
(It could result not too fast in map loading due to the low hardware configuration of the server)

As soon as possible I will add a page with more technical details on how
to set up such a link.

Thanks,
and hope to see you in Lausanne.

Massimiliano

Cool, Cool, Cool....

I like it....

I had an issue with popups, but that's normal when you block them....
Worked well in firefox

IS the watershed a pre defined boundarie, or is GRASS running the
r.watersheds and creating it from scratch? Does this get cached? Or is
it a predefined watershed boundary?...

The ROI requirement was not clear at first, but trial and error worked
that out....

I perosnaly like zoom tools that can draw an extent box instead of a
point and given zoom factor, but that's my preference

Load time and processing time is a little slow, but that's secondary.
I'm assuming that's across the board.

For others that are going to try it out this is the process I tried
1. load page
2. zoom into an area (mag +) so you can see some individual pints
3. Chooce the ROI tool (far left icon)
4. draw ROI (if there is processing of the watersheds then I assume the
larger the ROI more processing time)
5. Select watershed from point (Third from left)
6. Select a red point inside the ROI (notice the ROI only comes up when
you switch tools and select point)
7. Tri the INFO button to learn more about each site (7th from left)

So... Cool, I like

What other widgets are connected to GRASS?...

I look forward to the technical docs and seeing more people use it.

Sorry,

I failed to mention the stats (pie chart icon).....

Good application to show how data can processed and analysed

Again, congrats

Cheers

Hi Dave,
speed is just a matter of hardware in this case
Yes, basin are dynamically generated, when you click the map or a station it get the coordinate, then they are passed to GRASS.
With a new GRASS command that I wrote, the nearest pixel coordinate belonging to a river is selected, and the r.water.outlet is run. The raster basin generated is then converted in vector and represented.

For statistics, a MASK fitting the basin is generated and then r.stats, r.univar are run.

Also PanaChart php library was used to generate the graph.

That's all.
Again sorry for the slowness ! It will be better in future...

Cool,

Can't wait for a howto for all us GRASS users that lack the MAPSERVER
know how.

Again, Good work

Very cool! Thanks for sending the link. You should also put it in the MapServer Gallery, if you haven't done it yet.

The response seems reasonable (maybe a little slow). The watershed statistics are returned pretty fast. It would be interesting to see this on a more capable hardware.

Very nice, very!

I would change "Watershed from Point" -> "Watershed from Station" or
so; pixel vs. point might be ambigious for some folks.

Congrats!

Hi Massimiliano,

Great work. Look forward to see you in Luassanne
and exchanges notes on some similar work that
we have done here.

Kind regards

software counts too. Your solution is a lot faster than ArcIMS+ArcWeb
(cheaper as well!).

example:
go to ESRI homepage and click the "driving directions to HQ" link on
the About page, and wait..... I have never successfully finished this
test - it just stalls.
