Shapefile

Esri Shapefiles can be imported into Studio. The Shapefile format contains a table with one geometry column providing a geometry (point, line or polygon) per row and a number of data columns.

Loader	Characteristic
File Format	Esri Shapefile
File Type	Multi-file, binary
File Extension	`.shp`, `.dbf`, `.prj`, `.cpg`
MIME type	`application/octet-stream`

Shapefile is a multi file format, and each shapefile is stored in multiple files (with the same basename but different extensions stations.shp, stations.dbf etc. All the files related to one shapefile need to be provided / be accessible when opening the file.

When loading Shapefile from your local computer, all files representing a Shapefile should be provided at the same time, e.g. by selecting multiple files in the Studio file selection dialog, or by collecting the required files in a zip file.
When loading a shapefile from a URL, the Studio platform expects all the component files of a Shapefile to be located in the same folder and have the same base name with different file extensions:

Shapefile files

File Type	Description	Comment
`.shp`	Geometries (geometry column)	Required
`.dbf`	Data (all other columns in the table)	Required
`.prj`	Specifies Coordinate Reference System for the `.shp` file	Optional
`.cpg`	Encoding format for strings in the `.dbf` file	Optional
`.shx`	Index file (typically not needed)	Optional

Normally there is always a <filename>.shp and a <filename>.dbf file pair, containing geometry and data, respectively.
Studio will also use <filename>.prj, <filename>.cpg and <filename>.shx files if provided.
Other Shapefile file extensions are ignored by the Studio Platform and need not be supplied.

Note that the Shapefile format defines additional "sidecar" file types. These are optional files (per the Shapefile specification) that are less commonly used, and are ignored by the Studio Platform.

Coordinate Systems

Arbitrary coordinate reference systems are supported for Shapefiles. Such coordinate systems are reprojected to WGS84 on import. Studio leverages a selection of the best available reprojection libraries and provides extensive support for different coordinate reference systems.

Troubleshooting

No data columns: If only the .shp file was opened, only the geometry is included,
Incorrect strings: Encodings may not be correct without the .cpg file.
Geometry projection issues: geometry may fail to load or be visualized incorrectly without the associated .prj file.

Also note that there is a very large number of possible projections and it is hard to test that every possible projection is supported. If your data is old or known to be problematic, it may be worth double checking that things look correct after importing.
