GE-Graph – Draw overlay graphs and data on Google Earth

GE-Graph is a fantastic visualization tool for Google Earth created specially for giving presentations that leaves your audience’s jaw dropping. GE-Graph is a free program that takes data in a simple tabular format and then lets you plot it as 3 dimensional polygons and bars directly over Google Earth. The result is incredible, though surprisingly something that we are used to seeing – the news weather report for example.

GE-Graph takes KML files saved by Google Earth and uses those files to generate graphs on the maps. The resulting file, generated by GE-Graph can be exported back to Google Earth.

You have to enter data in GE-Graph using its table editor. You can paste columns directly from a spreadsheet or import them as CSV files created in the correct format -latitude, longitude, name and value to be plotted. Set the type of graph you want to plot – flat graphs that are pinned to the ground, with colors describing the value or 3D bars with their value indicated on the sides. You can also create 3D bars where the height varies according to the data. Set color of the graph, the size and so on.

Checkout some of the demo files found on the website. You will find lots of additional resources too. Download them and import it to Google Earth to see the results. This would be one hell of a presentation!

GE-Graph is compatible with the recent Google Earth version 5.0.

Whenever the computer is lagging or some application is taking too long to respond, we usually fire up task manager and look under the Performance tab or under Processes to check on processor utilization or the amount of free memory available. The task manager is ideal for real-time analysis of CPU and memory utilization. It even displays a short history of CPU utilization in the form of a graph.

How to Schedule Changes to Your Facebook Page Cover Photo

Facebook’s current layout, the so called Timeline, features a prominent, large cover photo that some people are using in a lot of different creative ways. Timeline is also available for Facebook Pages that people can use to promote their website or business or event. Although you can change the cover photo as often as you like, it’s meant to be static – something which you design and leave it for at least a few weeks or months like a redesigned website. However, there are times when you may want to change the cover photo frequently and periodically to match event dates or some special promotion that you are running or plan to run. So, here is how you can do that.
