What file format do I use to upload my lat/lon coordinate pairs?
The file format can easily be created in any spreadsheet program or text editor. Click Here to download an example data set. The first line (header) in the file consists of three column names. The name of the columns does not matter, but the data in Column 1 is a user-supplied ID for each coordinate pair. The second column contains a latitude (Y)value in decimal degrees NAD83 or WGS84 datums. The third column containts a longitude (X) value also in decimal degrees NAD83 or WGS84. Note that in the Western Hemisphere, longitude will be a negative number. The file must be saved as a tab-delimited text file (.txt) or a comma separate value file (.csv). The file may not contain blank lines.
