Support Different Spatial/Geometrical Data Format

[Sarwat]

GeoSpark need to support different input and output data format:

GML(Geography Markup Language)
WKT (Well-Known Text)
WKB (Well-Known Binary)

[sabman]

Add the very popular GeoJSON to the list

@Sarwat looks like geojson and wkt is supported see:

Thanks for your interests!

Yes. We now support GeoJSON and WKT as inputs. You can try them.

May I ask how to you support it? By this I mean, I have a CSV file which is in WKT... should I just change the format?

[lrojas94]

Also, note this line says wtk instead of wkt.

Hi,

We support CSV, TSV, GeoJSON, and WKT.

For CSV and TSV, you need to specify from which column (base is 0) the spatial coordinate data starts in case that the first several columns are IDs or other useless information. Then the reader will read coordinates from that column, for each row.

For GeoJSON and WKT, you can directly load data from the source file.

[jiayuasu]

That WTK is a typo and it will be fixed along with other new features in the next few weeks.

[sabman]

@jiayuasu see #7 for more typos

[jiayuasu]

@sabman Thanks for pointing this out. I will fix it later on.

Do you support shapefile also?

[jiayuasu]

Hi, currently, no. But we can add it in the future version. We now support reading/writing csv, tsv, wkt and GeoJSON.

Hi, do you support shp files yet as input format?

[jiayuasu]

@rroyhere Sorry. We haven't finished the shape file input support. You probably can convert it to WKT or CSV and then use GeoSpark to load it.

[geoHeil]

Actually, using geotools in spark to perform such conversions in parallel fashion is pretty easy and opens a door to a variety of geo-formats.

ESRI ShapeFile support is now available in GeoSpark 0.8.0.

[rroyhere]

This is awesome to know. Can't wait to try it out. Thanks

Are there any plans to add other geospatial formats? Geopackage would be amazing!
