Supported Point File Formats
Coordinate data must be uniformly organized into columns with all coordinates in a given column being relative to the same coordinate reference system.

Supported Vector File Formats
Here is the list of supported file formats for Vector File Conversions. The output file options will only list files that are compatible with the loaded data type.
Note: When loading data with more than one supporting file (for example, an external reference format such as .prj), be sure to select and import all associated files. Unlike desktop software, websites are only permitted access to the files selected by the user.

Supported Raster File Formats
These are the supported file formats for Raster File Conversions. After data has been imported, the Output File Extension drop-down list will be automatically limited to file types that are compatible with the loaded data type.
Note: If a file type includes supporting files, all associated files must be loaded. See the list of supported reference files below.

Supporting Reference Files
Some raster file types require other reference files to be loaded concurrently. These additional reference files can include (but are not limited to) the following:
- .rsf (from Geographic Calculator Desktop),
- .prj
- world files (first and last letter of format name, with “w” added to the end. E.g. JPG = “jgw”)
- .tab (for some formats only)
