Dear Yelena,
The best way to do this si to follow the pattern of the plantations example.
If you open the file ( [LINK][1] ) using winzip you will notice that there is an attribute called "geometry" that is marked as a "From CSV" kind os attribute.
So add an attribute called "geometry" to your survey and mark it as **"From CSV"**.
In the CSV file with the plot locations, you actually don't need to set any values for latitude and longitude, but the columns NEED TO BE THERE , so just use zeroes (0) as values.
This is how the CSV file for plantations look :
id,latitude,longitude,geometry
Eucaliptus_01,0,0,"<Polygon><outerBoundaryIs><LinearRing><coordinates>....../coordinates></LinearRing></outerBoundaryIs></Polygon>"
Pinus_01,0,0,"<Polygon><outerBoundaryIs><LinearRing><coordinates>...</coordinates></LinearRing></outerBoundaryIs></Polygon>"
So as you see the geometry attribute is there as one of the columns.
The geometry values need to be KML polygons. In order to create KML polygons you canuse QGis to transform shapes to KML and thenupdate then [upload it to a Fusion Table sothat Table][2] so that you get the polygon values as a CSV file. You can also use [shpescape.com][2] [shpescape.com][3] to upload a shapefile to a fusion table.
Letme Let me know if you need more help!
