EDM implements Moderate Resolution Imaging Spectroradiometer (MODIS) reflectance true-color (500m resolution). This image source differs from the existing MapQuest and Google images in that it is a daily satellite image (from May 2012 to present).

EDM now has a new .dbf +.csv file output format for shapefilesExit When saving time-varying data to Shapefiles, a .csv file is produced containing the time-varying data while the .dbf file contains only static information about the shapes.

The number of .dbf rows matches the number of shapes, whereas the number of rows in the csv file = shapes x timesteps (less any missing data -9999 which is not written).

If small enough, the .csv file can be loaded into QGIS  Exitand manually “related” to the shp data, thus producing a time-series avoiding the previous custom workarounds to the .dbf file format limit of 255 column.

Note the following characteristics of the .csv file:
  • ID is an integer index that matches the shape index [0..shapes-1].
  • Station will only be present if the data has a string station name.
  • Longitude and Latitude will always be present. For non-point data this is the shape centroid.
  • Depth(m) is present only for data that has depth (or may just be 0).
  • The date-time column will be named according to the timestep size: YYYYMMDDHH or YYYYMMDD or YYYYMM or YYYY.
  • The time-varying scalar data value will be in a column named Value. For 2D/3D vector data (wind, current) the columns will be U_Value, V_Value, W_Value.
  • The lines in the csv file are ordered by ID then Time.
Other additions and enhancements to this version include:
