Build a Google Earth Interface on Oracle Database XE
Get an overview of spatial data, explore ways to add spatial attributes to existing data, and learn how to use Google Earth to "fly" over aerial imagery including that data.
Does anyone have an awk script that converts/translates an ascii .csv file to a Google Earth .kml file?
The .csv would typically look like:
X_Longitude_Coordinate,Y_Latitude_Coordinate,Elevation,Point_Number
Thank you,

Hi Gurus of Unix, is posible to Install Google Earth in Solaris
I download this packets :
GoogleEarthLinux.bin
I Change the permission
chwmod +x GoogleEarthLinux.bin
after that
I do ./GoogleEarthLinux.bin
andres@opensolaris:~/Downloads# sudo ./GoogleEarthLinux.bin

img2google - Create Google Earth KML overlay tiles from bathymetry Mercator img grid
SYNOPSIS
img2google -Rwest/east/south/north[r] [ imgfile ] [ -Amode[altitude ] ] [ -C ] [ -Ffademin/fademax ] [ -Gprefix ] [ -LLODmin/LODmax ] [
-Nlayername ] [ -Tdoctitle ] [ -UURL ] [ -V ] [ -Z ]
DESCRIPTION
img2google reads a 1x1 minute Mercator surface relief img file and creates a Google Earth overlay KML file and associated PNG tile for the
specified region. If no input file is given we use topo.11.1.img.
-R west, east, south, and north specify the Region of interest, and you may specify them in decimal degrees or in
[+-]dd:mm[:ss.xxx][W|E|S|N] format. Append r if lower left and upper right map coordinates are given instead of w/e/s/n. The two
shorthands -Rg and -Rd stand for global domain (0/360 and -180/+180 in longitude respectively, with -90/+90 in latitude). Alterna-
tively, specify the name of an existing grid file and the -R settings (and grid spacing, if applicable) are copied from the grid.
OPTIONS
imgfile
An img format bathymetry/topography file such as those created by Sandwell and Smith. If this files does not exist in the current
directory and the user has set the environment variable $GMT_DATADIR, then img2mercgrd will try to find imgfile in $GMT_DATADIR.
-A Selects one of 5 altitude modes recognized by Google Earth that determines the altitude (in m) of the image: G clamped to the
ground, g append altitude relative to ground, a append absolute altitude, s append altitude relative to seafloor, and S clamp it to
the seafloor [Default].
-C Turn on clipping so that only portions below sea level will be visible in the image [no clipping].
-F Sets the distance over which the geometry fades, from fully opaque to fully transparent. These ramp values, expressed in screen pix-
els, are applied at the minimum and maximum end of the LOD (visibility) limits, respectively. [no fading (0/0)].
-G Specify the prefix for the output image file (the extensions are set automatically). Default uses the naming
topoN|S<north>E|W<west>.
-L Measurement in screen pixels that represents the minimum limit of the visibility range for a given Region Google Earth calculates
the size of the Region when projected onto screen space. Then it computes the square root of the Region's area (if, for example, the
Region is square and the viewpoint is directly above the Region, and the Region is not tilted, this measurement is equal to the
width of the projected Region). If this measurement falls within the limits defined by LODmin and LODmax (and if the region is in
view), the Region is active. If this limit is not reached, the associated geometry is considered to be too far from the user's view-
point to be drawn. LODmax represents the maximum limit of the visibility range for a given Region. A value of -1, the default, indi-
cates "active to infinite size." [always active].
-N Append the layername of the image (use quotes if strings contain spaces) [topoN|S<north>E|W<west>].
-T Append the document title (use quotes if strings contain spaces) ["Predicted bathymetry"].
-U By default, images are referenced locally relative to the KML file. Specify an URL to prepend a server address to the image name
reference [local].
-V Selects verbose mode, which will send progress reports to stderr [Default runs "silently"].
-Z Uses zip (which must be installed) to create a *.kmz file for easy distribution; append + to delete the KML and PNG file after zip-
ping [No zipping].
EXAMPLES
To create a 10x10 degree Google Earth KML tile for the region -R170/180/20/30 using the default topo.11.1.img and output naming convention,
try
img2google -R170/180/20/30
To make the same tile with the previous topo.10.1.img, run in verbose mode, clip so only oceanic areas are visible, name the output oldim-
age, specify the KML metadata directly (including setting the image altitude to 10 km), and make a single *.kmz file, try
img2google topo.10.1.img -R170/180/20/30 -AA10000 -C -Goldimage -N"My KML title" -T"My KML title" -Uhttp://my.server.com/images -V -Z
