Representing your geographical data on Google Earth has never been so easy

GEPlot is a Windows application for plotting contour lines (also known as isolinesisopleths, or isarithms) and grids over Google Earth. GEPlot allows you to plot your geographical data both over a small domain and over the whole world. GEPlot produces KML (Keyhole Markup Language) files and their compressed version (KMZ) which can be directly loaded in Google Earth. The input data can be ASCII (X, Y, Z format or Golden Software Surfer GRD format) or Microsoft Excel organised as X, Y, Z columns. GEPlot allows to produce grid and contour plots for any georeferenced variable, such as, for example, orography, land use, air pollution levels, noise levels, population data, etc.

  • Loads data on regular grids from ASCII files (CSV, DAT, …)
  • Loads data on regular grids from ASCII GRD files (Golden Software Surfer format)
  • Loads data on regular grids from Microsoft Excel files (XLS and XLSX)
  • Batch processing: automatically create KML files from all the input files in a specific folder
  • Manages UTM coordinates (both m and km), metric non-UTM coordinates (or UTM traslated), and geographical coordinates (longitude and latitude)
  • Allows to select colours, width and height of contours
  • Allows to select colours, width, height and opacity of grids
  • Allows to save and load frequently used levels
  • Allows to save and load plot configuration
  • Allows to create plot legends
  • Calculates statistics (average, percentiles, etc.) of the input data
