Google Earth Water Levels (XYZ Plot)

Report Name: Google Earth: Water Levels (XYZ Plot)

 

Report Type: Standard

 

Description: In order to use EQuIS Google Earth Reports for commercial purposes, you must obtain the appropriate license.

 

The output of this report shows the water level represented as a three dimensional contour. The Places tree contains folders for each of the days on which water level measurements exist. Values from each day are interpolated using a Nearest Neighbor algorithm. The interpolated values are then displayed using a color palette ranging from blue (low) to red (high). Each color in the palette is shown as a folder, so the user can check/uncheck that folder to show/hide values in that range.

 

In addition to the color palette, the elevation of each point (distance from the ground) represents the relative value to other points. For example, the lower valued points are close to the ground; whereas the higher valued points are farther above the ground. This relative distance from the ground makes it possible to view a 2D contour (by reducing the tilt in Google Earth to look straight down from above) or to view a 3D surface (by increasing the tilt in Google Earth to look from the side).

 

This report includes data over the selected date range. You can drag the time slider, or press the Play button, to watch the values change over time. The report provides the option to create Contours, Color grids, Dot Plots or Surface Plots.

 

The Google Earth output, which shows a table when clicking on a location, has been improved for readability by adding color to alternative rows.

 

This report is computationally intensive, and interpolates a unique grid for each date. For example, a site may have only 100 different records, but 25 different dates. In this case the report would interpolate 25 different grids, and potentially consume vast system resources. Please also note that there are limitations to the size and complexity of KML/KMZ files supported in Google Earth. Selecting too many parameters and/or too large a date range may result the following information message:

 

"Report did not generate output. Please try again.Please reduce the number of parameters and/or dates to be contoured (params=P,dates=D)"

where P = the number of input parameters, and D = the number of input dates.

 

Notes:

EQuIS Google Earth Reports do not actually require or directly use Google Earth or any other Google service. The reports merely create KML (*.kml, *.kmz) files. Some of the charts are created using Google Charts (by sending individual data points for the chart).

Other applications besides Google Earth (such as ArcGIS Explorer) can read *.kml files. EQuIS reports have not been tested extensively with anything other than Google Earth.

An EQuIS license does not provide legal license or permission to use Google Earth. The end user is responsible to make sure he/she is using Google Earth legally.
