File formats supported for importing data

Koordinates support multiple file formats for both import and export. Below, we provide a brief introduction to some of the file formats we support.

A note on importing data

Note that, when importing data, you are able to put multiple types of data into a single data archive. Koordinates will extract them and either create individual data layers or merge them into a single layer.

Quick overview of import file formats

Vector and tabular

  • Shapefile (.SHP)
  • MapInfo TAB (.TAB)
  • Esri File Geodatabase
  • GeoPackage / SQLite
  • GeoJSON
  • CSV
  • XLS, XLSX (Excel Spreadsheet) and ODS (OpenDocument Spreadsheet)
  • Esri Coverage

Image/Raster

  • GeoJPEG
  • GeoTIFF, TIFF with world files (.TFW)
  • JPEG2000
  • Gridded Raster
  • ESRI Binary Grid
  • ESRI ASCII Grid
  • GeoTIFF

If your data is in a format not listed above, you may be able to convert it into a supported format.

MapInfo TAB

MapInfo TAB is a proprietary format used for vector datasets, and is primarily for use in the suite of MapInfo GIS applications.

Like other GIS file formats, TAB files contain a few different kinds of file formats, which each do a different work. These include:

  • .tab: The main file that links all the other files in the dataset
  • .dat: This file stores the attribute data - that is, the the non-spatial data in your dataset
  • .id: This links graphic data to the database information
  • .map: This has the geographic information that enables the data to be represented on a map.
  • .ind: This is an index file for tabular data

GeoTIFF

A GeoTIFF file is a georeferenced TIFF, which means it can have geographic information such as map projections embedded within the TIFF itself. This means that a GIS application can position the image in the correct location

TIFF is an open and non-proprietary file format that is widely used for raster imagery and aerial photography. Strictly speaking, GeoTIFF is a metadata format, but the TIFF format enables both the data and metadata to exist in the same file.

Shapefile (SHP)

Shapefile is a GIS format developed for vector datasets. It should work in most common GIS applications.

Your Shapefile download will contain a range of different file formats, which each do a different kind of work within your application. These are:

  • .shp: this file represents the feature geometry - i.e. the points, lines and polygons in spatial dataset.
  • .shx: this file represents the ‘shape index position,’ and is used to search forward and backwards.
  • .dbf: this is the database file, which contains attribute data and object IDs.
  • .prj: this file will contain the projection information.
  • .cpg: this identifies the character encoding for the .dbf database file.

GeoPackage / SQLite

Geopackage is a SQLite database format from the Open Geospatial Consortium, which is intended to be a modern alternative to older formats like Shapefile.

Geopackage is an open and platform independent format, and is supported in a range of applications. It is an especially useful format for development of mobile applications for smartphones and tablets.

File Geodatabase (FGDB)

File Geodatabase is a proprietary Esri database format that is used for more complex uses of GIS datasets in Esri software. This format is often used because it allows for much larger file formats and can provide better performance than Shapefiles.

GeoJPEG

GeoJPEG’s are JPEG files that have geographic information attached within the file -- that is to say, it is a georeferenced JPEG. When downloaded, the .jpeg file will be accompanied by a .jgw file that will carry the associated geographic information.

Learn more about GeoJPEG.

JPEG 2000

JPEG 2000 is the newer version of the JPEG file format, which is intended to provide better compression and image quality than an ordinary JPEG. While JPEG 2000 has some benefits to JPEG, it is not as widely supported as JPEG.

Datasets downloaded in JPEG 2000 will be georeferenced with embedded XML.

ASCII Grid

ASCII Grid is a proprietary file format from Esri.

Learn more about ASCII Grid.

CSV and GeoCSV

Comma Separated Value format - or CSV - is a format that enables tabular data to be easily exchanged by different applications. GeoCSV is its geospatial extension.
