I was trying to draw kml that are (one degree in gap) meredians and parallels for Austrailia. e.g see i tried to draw 142 degree and 11 degree lines using fishnet in arcmap but when imported into Google Earth they shifted a bit. I used WGS84(EPSG:4326) when creating lines.I supposed that google earth uses EPSG:4326 (I also tried EPSG:3857) as described at here, here and here.
Below are the steps i did to generate KML as attached above-
- Open Create Fishnet Tool in a dataframe set to WGS84(EPSG:4326) and assign the parameters as -
From the spatial extent i am generating fishnet on i.e. 100E, 3S to 155E, 50S i counted the number of parallels(50-3=47) and meridians(155-100=55) and used this number as row and column number in the fishnet tool as shown above.
Then i used Densify tool to generate sufficient points in the lines(0.001 degrees distance interval) whereas projection does not shifts the whole feature.
I defined the projection of the layer WGS84(EPSG:4326) using Define Projection tool(I also tried EPSG:3857)
Finally i reprojected the line layer into WGS84(EPSG:4326) using Project tool(I also tried EPSG:3857)
And exported the lines into kml using Layer to KML tool.
Now, Problem is when i zoom in the exported kml in google earth i see a shift as shown in the attached.So i need a kml(with generation method) in the above spatial extent(100E, 50S to 155E, 3S) that matches exactly with the grid of google earth irrespective of zoom level
I am in Windows 8 and Arcmap Advanced 10.3.0.4284 and by WGS84 i mean as below
GCS_WGS_1984 WKID: 4326 Authority: EPSG Angular Unit: Degree (0.0174532925199433) Prime Meridian: Greenwich (0.0) Datum: D_WGS_1984 Spheroid: WGS_1984 Semimajor Axis: 6378137.0 Semiminor Axis: 6356752.314245179 Inverse Flattening: 298.257223563
