Import CSV

CSV files that contain coordinates can be opened using the Open Generic Text File option in the File Menu. They may also be opened with the open data options, which will provide the same Generic Text File Import Options dialog.

Some special CSV files will load automatically without displaying the import dialog, such as USGS EarthExplorer CSV Coverage files.

CSV files that do not contain coordinates can be appended to related vector features by Joining a Table.

Export CSV

The Export CSV command allows the user to export any loaded point data sets to a CSV (Comma Separated File) file. Area and line features may also be included in the export based on an additional option.

Export loaded vector data to a csv file from the File > Export > Export Vector/Lidar Format... option, or by right-clicking on a specific layer in the Control Center going to Layer > EXPORT and choosing CSV as the export format. Multiple files can be batch converted to and from the format from the Batch Convert/Reproject tool.

CSV files can also be exported from within a subset of tools, including just the attribute values from the Attribute Editor, profile values from the Path Profile tool, and additional reports. Keyword Link IconSearch Index

When selected, the command displays the CSV Export Options dialog which allows the user to set up the export.

The CSV export options are grouped in to various categories of settings that control the output data and formatting of the generated CSV file.

Field Separator

Specify the delimiter used to separate values in the output file. Note that per the default extension .csv, this would typically be comma separated. The extension could however be customized during file naming in the subsequent dialog.

Coordinate Precision

Use the default coordinate precision, which is typically 3 decimal places for planar units, or specify an explicit decimal precision for the output coordinates.

Coordinate Formatting

Export Area and Line Features (Use WKT Coordinate Format)

The default csv export will only include point features. Check this option to also include areas and line features.

Examples of WKT formatted coordinatesClosed
"POINT( 57.5695686340 -20.2793235779 )"
"LINESTRING(53.6616037695 -19.5368052132, 54.2376101498 -19.8248084034, 54.9288178061 -20.2280128696, 57.0024407750 -20.6168171762, 59.3352666151 -19.3784034587, 59.5512690077 -19.2200017041, 61.9560956453 -18.3991926122)"
"POLYGON(( 54.5544136589 -19.7492075660, 55.5192243459 -19.2164016642, 55.9868808834 -20.0632391780, 53.9800217541 -21.1715046673, 54.5544136589 -19.7492075660 ))"

Include Elevation Values for Each Point (If Available)

Check this option to include elevation values as a coordinate value points that contain them.

Write Elevation Column Before XY Column

Check this option to make elevation the first value in the file.

Export Separate Lat/Lon Coordinates for Each Point

Enabling this option will include LATITUDE and LONGITUDE columns in addition to X and Y when the projection is not Geographic.

Format Lat/Lon Coordinates with Position Display Format

LATITUDE and LONGITUDE attributes (when being included) will use the current Position Display Format setting in Measure/ Units Configuration for formatting those values.

Use Comma for Decimal Separator

This setting will use a comma as the decimal separator for coordinates, rather than a period.

ADVANCED: Export ECEF (Earth-Centered Earth Fixed)

Check this option to export X and Y values as ECEF.

Coordinate Column Names

The names of the coordinate values will populate from the loaded data being exported. Type a new name to modify the column names for the exported coordinates.

Attribute/ Field Options

Include Column Names in First Row of File

This is enabled by default. This will include a label header row in the first row of the file that identifies the subsequent values. This comes from the attribute names, or the column names otherwise designated on the dialog.

Include Attribute Values

If this is not checked, only coordinate and label values will be exported. When checked, selected attribute values will be included in the export, even if all of the attribute values are blank. The default is for all attribute values to be included. Press the Select... button to choose a subset of attributes to include.

Press the Check All or Clear All buttons to bulk select or deselect attributes. Use the arrow buttons to change the order of attributes in the exported file. The arrow with the underline will move the highlighted attribute to the bottom or top of the list.

Use UTF-8 Encoding for Text Values

When this option is not checked, the character encoding defaults to ANSI. Check this option to encode the characters in UTF-8. This provides support for additional language characters.

Add LAYER Column with Feature Description if Applicable

Check this option to include a value in each row listing the layer name the feature is contained in.

Add SYMBOL Column if Applicable

Enable this option to include a SYMBOL value in each row that specifies the name of the symbol used to symbolize the feature in Global Mapper. Global Mapper will automatically recognize this value when reloading the file. For more information see Special Attributes & ASCII Field Options

Add Formatted UTM-K Coordinate Column

Check this option to include coordinates in the UTM-K format used in South Korea. They are rounded to the nearest 10 meters and have an X and Y Korean character at the start of the coordinate specifying the UTM-K X and Y zones.
