Read and compare the IEEE standard 141 GE Flicker Curve vs. The IEEE 1453 Flicker Meter standard. This whitepaper describes and compares two of the IEEE Flicker standards: the older standard 141 (the GE Flicker Curve), and the newer IEEE 1453 (Flicker Meter standard). The 141 standard is based on studies performed on human perception of light. GE-Graph was developed to generate graphs from kml files saved by Google Earth. The data can also be typed into the application or pasted from other applications. The file generated by GE-Graph can be exported to Google Earth. Make graph into GE to illustrate your presentations, papers, etc. Good tool for Geography educators. There is a similar problem here, but I am looking to prove this statement by contradiction, and I am having difficulty understanding these solutions. Here is what I've got so far.
If you were wondering how I created the Google Earth rainfall plot in yesterday’s post on FAO climate data, I didn’t use one of the shapefile to KML converters I’ve posted about. Instead, I used a free program called GE-Graph that takes tabular data and lets you plot it in colors and polygons that depend on the value you’re plotting.
You can enter data directly in GE-Graph using its table editor, including pasting columns from a spreadsheet, but it will also accept CSV-format text data createable in a spreadsheet in the proper format:Name, latitude, longitude, value to be plotted (data only, no column headers).
Open the data in GE-Graph (click on image for larger view):
Here you can set:
Graph of Type: Flat (pinned to the ground, with colors describing the data value) or 3D (Polygons, with the number of sides set by the dropdown). You can also link data to a custom KML polygon file (e.g. state borders), and use those as the plotted shapes.
Height (3D only): Whether the height varies with the data value or not
Color: Whether the color of the polygon or flat area varies with the data value; colors set using the Color Scale section
Size: The size of the flat area or polygon as plotted in Google Earth
Ge Graphics Cards
Ge Graphite Lubricant
… and so on – you can set the specific scales for the data, or have GE-Graph do that automatically, enter labels, specify a grid, etc.. There’s a full help section included with the program.
Here’s the plot from yesterday’s post, created with the above settings and data, as displayed in Google Earth:
More examples of the kinds of plots that GE-Graph can create, along with the download link, are available at the GE-Graph website.
