[Geomoose-users] Layer functions

This makes me ponder whether we could replicate something like a lot of ArcGIS Server and FLEX applications are going to for print tools.  Take a look at this application.  http://gis.anokacountymn.gov/geoprime.html   Click the "Print" button and you'll notice you can move the map around on the print preview window and enter a title right on it. Also has options for scale of map.  Not sure if this could be replicated with JavaScript or not.  I would guess a lot of it could be.  

I would envision this could become another print service option.  This method would be entirely client side.  This type of print service is what I have been thinking we should try.  Now it's just a matter of finding some funding if enough users are interested.  What do users think about that type of print service?  The only limitation I can think of is generating high resolution maps.  If you want high resolution maps you would need to revert back to the server side print service (print.php).

It would be nice if GeoMoose could enforce the aspect ratio of the rectange to be the same as the printed area.  I have one site (still on v1.6) where they are very particular on being able to select the extent, scale, and page size.  I'm sure they'd like to be able to see the printing extent shown in the browser window so they could move it slightly (and see the rectangle size change if they type in a scale value, or select a different page size).

At first I thought, how'd they get the extent to match the aspect ratio on the PDF, but then saw they have locked the selection feature to a square of only two sizes.    Could this be done with an OL regularPolygon to create the extent and then modify the print service to send that extent and pixel size to print.php instead of the map extent and size?

A couple of the things I like (I think..) about GeoExt is the fact you can move the DIV/results windows around in the browser (http://dev.geoext.org/trunk/geoext/examples/print-extent.html), and the ability to select the printing extent inet(http://dev.geoext.org/trunk/geoext/examples/print-extent.html).

Where these libraries can really help out is when processing data returned from a service.  For example, when you do a query and get more than a couple matching records, displaying the information in the tab makes it difficult to interpret the results.  Putting the results into a tabular format, in a DIV that can take more space than the tabs allow, is a much easier way for people to get the information.  jQuery and the other libraries make the creation of tables much easier.  They do add dependencies and increase the size of the js file, but this has to be balanced with the speed that the application can be developed and functionality they provide.  As a user extension, the developer can decide if the library is a appropriate for the application.

We essentially created an icon toggle because we were running out of screen space to put the icons next to the layer.  You'll see there are a couple extra icons already there like metadata and identify.  It wouldn't be hard to add the "zoom to" function.  I'm not a big fan of right-click menu's in web apps either.

For example he has the open attribute table working for search results.  It's pretty nice.  It's not a public app, but we could show you if you want to see how it works sometime.  Just shoot us an email offline. This fits nicely in with the user extension concept Dan started in the last version of GM.
