Overview
Note
- Sedona uses 1-based indexing for all raster functions except map algebra function, which uses 0-based indexing.
- Sedona by default enforces geographic coordinates to be in longitude/latitude order.
- By default, all raster cell world coordinates correspond to the real world coordinates of the leftmost top corner of the cell.
Sedona SQL supports raster data sources and raster operators in DataFrame and SQL. Raster support is available in all Sedona language bindings including Scala, Java, Python and R.
var myDataFrame = sedona.sql("YOUR_SQL")
myDataFrame.createOrReplaceTempView("rasterDf")
Dataset<Row> myDataFrame = sedona.sql("YOUR_SQL")
myDataFrame.createOrReplaceTempView("rasterDf")
myDataFrame = sedona.sql("YOUR_SQL")
myDataFrame.createOrReplaceTempView("rasterDf")
You can find example raster data in Sedona GitHub repo.
