Create sample kml files for testing #11

Closed perrygeo closed 12 years ago

perrygeo commented 12 years ago

We need to do a basic reality check of whether the Google Earth API will perform well enough for us. To do that we'll need a set of layers created from the south coast study region datasets. We won't need all the layers, just enough to handle the following cases:

Complex vector/polygons Raster data using SuperOverlays Regionated Point Data Temporal data

The data sets chosen should be useful when displayed together so we can test performance of multiple layers displayed at once.

These layers should be put onto one of the servers at a publicly accessible url so all the developers can access them.

Chris has created some test layers here in arc2earth. http://marinemap.org/kml_test/

I've also converted the substrate data using a geotiff he provided and gdal2tiles http://marinemap.org/kml_test/cburt/SubstrateProjected-ok/

We've found some issues where in Google Earth 5 some "banding" shows up near tile edges. The work around for this is to turn terrain off. I've filed an issue on the Google Earth bug tracker: http://code.google.com/p/earth-issues/issues/detail? id=368&q=superoverlay&colspec=ID%20Type%20Summary%20Status%20Owner%20Stars

So far performance has been good using regionated kml files. The performance of the Earth API seems comparable to the desktop client.

I've updated that ticket on earth-issues with a clampedToSeafloor test:

So far we've tested point data using ports, and superoverlays using the substrate data. I think for this ticket to close, we need to test another, more complex point data layer, as well as a complex vector feature like the study region boundary. These should both be heavily regionated.

This ticket is completed as far as being an initial test of the viability of KML being used for marinemap.
