Sample hurricane data files are available at the website.Finally, EarthPlot can take position, view direction and speed data, and create an flyover path in Google Earth.EarthPlot is a great companion program to GE-Graph.ĮarthPaint 1.3: A while back, I had a couple of posts on how to add raster and vector graphic imagery to Google Earth as an image overlay. Here’s a screenshot from the website showing both post and contour mapping, plotted on top of a USGS topo overlay:Īnd a graduated raster map for a hurricane’s path and intensity: USGS urban orthophoto (color limited coverage area).

USGS digital orthoquad (black-and-white aerial photo).The image can either be a graphic file on your computer, or can be a geographic image loaded in from the TerraServer website (US only): Spider: Plots lines from an origin point to the data pointĮarthPlot can also take an image file, and convert it into a graphic overlay.Graduated Raster: Plots the size of a symbol based on a data value.Trajectory maps: Plots a line in 2D or 3D based on position and altitude.If the data is unevenly spaced, EarthPlot can convert it to an evenly-spaced grid using an inverse-distance algorithm. Contour Maps – Plots data in gridded format as colored contours.Post Maps – Simple plots of the data as a 2D or 3D post, with the data value plotted next to it.EarthPlot has several different plotting options: You can open CSV files directly, or copy and paste data from Excel or any other spreadsheet program directly into the program’s datasheet. If you’re interested in plotting spreadsheet data or creating annotated overlays in Google Earth, you should definitely check these out.ĮarthPlot 1.3: EarthPlot’s main function is to take data in spreadsheet form and plot it in a number of graphical formats. The most recent versions of their software are now available as freeware. Back in 2005, EarthPlot software released several shareware tools for plotting data and creating graphic overlays in Google Earth.
