Description
As discussed on the ML I need to show several geoPoint markers on a single map.
I searched for some helping tools in the framework and found the <screen name="geoLocation">
and the relative <request-map uri="geoLocation">
Unfortunately this can only be used to show on a Google Map a single geoPoint record providing its geoPointId.
In my application I have a sort of "event" entity.
Each event has the LAT and LON coordinates of where the event took place and I need to show on a map all the query-selected events.
In the attached patch there is an implementation of a "geoChart" framework screen that takes as input a geoChart map containing:
geoChart
- dataSourceId -> select the map system to be used (google, yahoo etc.) I do not like this mane. I think I will rename to mapProviderId but it is how it is named right now
- width
- height -> map dimensions
- center -> the center point of the map
- points -> the points array to be showed on the map
In the patch there are also some example screens (in the example application) to show how it works.
I think that the suggested screen is more general and can replace the actual one.
BTW:
1) Why the dataSourceId is in the GeoPoint entity ?
I think the GeoPointEntity should be independent of what map provider (if any) will be used to show it.
2) A further improvement to this will be to add an heatmap mode (just started looking at this code: http://code.google.com/p/jheatmap/) that can be used when points will be too many or whenever an average distribution is only required (but this will be another page).
I submit this patch in order to have a first review by you.
Thank you,
Bruno
