Instrument description and ways to get it.

This extensions allow running Google Earth and transfer vector objects from QGIS map canvas. Layers opened in GE are stored in temporary folder and removed after QGIS is closed. Layer symbology can be imported from QGIS layers or set up separately. If attribute table contains populated NAME field, its value is also imported. This tool works only with vector layers.

Native data CRS should be Geographic (lat/long), WGS 84 (EPSG:4326), data can also be in other geographic CRS, but will be treated as 4326. The CRS of the map canvas is not important, if you want you can set the projection to anything you'd like, only native CRS will matter. If after transfering, Google Earth zooms in to the area around 0,0, you need to check native CRS of your data, most probably it is not Geographic, but projected.

[править] Source code

You can obtain sources (GNU GPL v2) from our Github page:

[править] How does it work

After plugin activation a new toolbar appears

[править] "Send feature" tool

Qgis2google-02.png

This instrument is used to click on the feature of the active layer. The feature being clicked is converted in KML and transfered in Google Earth.

[править] "Send layer" tool

Qgis2google-03.png

This instrument transfers the whole active layer. Single symbol or unique value symbology can be imported as well as layer transparency.

[править] Plugin settings

Qgis2google-04.png

This button opens plugin settings dialog

Here you can configures alternative symbology to used when "Override layer's current style settings" is switched on.

[править] Demo

You can also check out the demo (how to open Ecoregions layer from Geosample data set in Google Earth).

Warning: video size is about 100 Mb.
