DROUGHT ANALYZER issue: to be fixed in DotSpatial - DotSpatial.Plugins.WebMap

For details see http://hydrodesktop.codeplex.com/workitem/8515

This bug is duplicated in a special case:

I open a project created by older version of HydroDesktop This project has the 'Online basemap' layer switched on and it also shows an unnamed point layer with empty attribute table.

Also see the attached screenshot for explanation.

Steps to duplicate in 1.5.7:

Open the dspx file in the attachment Run Interpolation Tool - Geostatistical methods

Suggested stable solution: Fix DotSpatial.Plugins.WebMap (it shouldn't be adding the temporary empty point layer to force change of map extent) and fix Geostatistical tool (handle correctly layer with NULL dataset)

Jiri, how I can reproduce situation when WebMap creates empty layer? I tried to reproduce by next steps:

Create new project Change current base map Save reopen saved project, but empty layer not created in this case.
