Hi,
In our project we will have multiple layers and I just need clarification that I'm selecting the correct layer type for each project
Layer 1
Static base layer
Layers 2 and 3
Mostly static items [should change position slightly and probably only once a day]
These items need popups, dragging capability and context menus.
Although I have concerns with performance I will use a SimpleMarkerOverLay due to the requirements above
Layer 4 GPS tracking
Dynamic Layer
Tracks 1 or more vehicle GPS location
Popups, dragging capability and context menus required
It would seem that for performance that an ImMemoryMarkerOverlay would be the best options however without the support [as I understand it] for Popups, dragging capability and context menus it would seem that we have to go with the SimpleMarkerOverlay again.
Layer 6 Vehicle Breadcrumb trail
Probably will be a InMemoryMarkerOverlay for performance reasons and also due to the fact that Popup info is required only without the need to drag or have context menus
Layer 7
Historical locations of items in Layers 2 and 3
Could be a lot of data
Once plotted it wont change
Probably will be a InMemoryMarkerOverlay for performance reasons and also due to the fact that Popup info is required only without the need to drag or have context menus
Queries
I have selected the SimpleMarkerOverlay due to the requirements for a context menu and drag and drop mainly. If this was available in the InMemoryMarkerOverlay then that would be a better choice.. Is therer a way to do this easily
As I understand it, with an InMemoryMarkerOverlay its easy to query the layers and also locate the features inside a polygon created on screen. Is it possible/easy to locate the Markers on a SimpleLayerOverlay that is contained within a polygon and also to use functionality such as Keepout regions.
Can you explain the differenec between a FeatureSourceMarkerOverlay and a InMemoryMarkerOverlay and where you would choose one over the other
Thanks and Rgds,
Liam
