GeoExplorer
Work has started to integrate OpenGeo's GeoExplorer as an alternate/replacement Map Viewing Client.
Why?
- Good for Users to use consistent tools across applications
- Good for Developers to be part of a bigger community
- We want to rewrite to have most of the app in static JavaScript anyway
- ease contributions from JavaScript developers (who may be put off the Python part)
- support caching
- There are some cool features available which we'd like to make use of

Issues with GeoExplorer
Outstanding
- Published maps:
geoexplorer/viewer.html#id
- Doesn't appear to read the config at all!
- Viewer sends about to geoexplorer/about.html
- How to edit Title/Abstract(Description)/Contact when saving a map?
- How to save a WMS Server when saving a Map? (
"source":"source78"
) - Not clear when saving whether this is a New map or an Update
- Should have a 'Save As' option
- No Mouse wheel to zoom
- scaleLinePanel ugly: remove the Scale Chooser?
- Layer-Switcher in Embedded View not as nice...why different UI (just that we have less space not a reason since we can collapse mini)
- Currently has issues with GeoExt 1.0 (
j is null
) - Not tried updating to latest GXP version from GitHub yet
Fixed
- Ext 3.0.0 -> 3.2.1 (Test they work ok with 3.0.0 too):
height: 27
(north) [GeoExplorer.js
&Viewer.js
]header: false
(westPanel) [GeoExplorer.js
]
- OpenLayers 2.9 -> 2.10
- Can remove the 'Patch the SphericalMercator layer' from the top of
GeoExplorer.js
- Can remove the 'Patch the SphericalMercator layer' from the top of
