btw aside of having an exception here; you have smth with your deps / jvm classpath:
KaTeX parse error: Can't use function '$' in math mode at position 5
that is not smth we bring into GT; that is smth on your host
It expects JSONs as inputs into arguments
not links to jsons
but be careful with percent ecndoing; passing jsons as arguments is not the best design decision :D
you can hijack the code and pass it inside manually for test purposes
but there nothing happende when i change the uri to http://0.0.0.0:9000/0/1/1.png?red={'uri':'http://127.0.0.1:1234/tiff/1/LC08_L1TP_015032_20180521_20180605_01_T1_B4.tif','band':4,'celltype':null}&nir={'uri':'http://127.0.0.1:1234/tiff/1/LC08_L1TP_015032_20180521_20180605_01_T1_B5.tif','band':4,'celltype':null} @pomadchin
Oh I see
FYI, last week at Phi week in Rome, we released an early adopter release of a new ESA platform for EO data processing. One of the backends is built entirely with GeoTrellis (https://github.com/Open-EO/openeo-geotrellis-extensions/).
We're also giving away 3-month accounts to interested beta testers: https://openeo.cloud/early-adopters/

Hey @pomadchin I want to run the ogc-example project, https://github.com/geotrellis/geotrellis-server/blob/main/ogc-example，How to write url？
@pomadchin Using graalvm in JIT mode (not a native binary) gave about a 7-10% boost in perf, but I wasn't able to figure out how to get a native compile working to really test the differences between java byte code and graalvms binary. Do you think it would be possible to do a native-image compile of geotrellis? (not using spark that is)
Hey @Max-AR I think I mentioned somehwere above, I don’t think it is possible right now to build native image: spark has complicated dependencies and java reflection calls, uses SPI etc
the same is applicable to some GeoTrellis dependencies (like geotools) and almost every GeoTrellis package: cassandra backend, raster package - uses SPI, etc
the same is applicable to some GeoTrellis dependencies (like geotools) and almost every GeoTrellis package: cassandra backend, raster package - uses SPI, etc
but what errors do you have?
I think i’ve seen before a docker image with Spark
Spark relies on the dynamic classload
But all good
:+1: good plan
btw if you will endup looking into it more dont heistate to drop stacktraces
I’m also interested in the native image so mb we can craft smth together :rocket:
hey @GofferdoXu
$ sbt
$ project ogc-example
$ run http://localhost:port/
@Max-AR oooooh one thing
an issue can be related to jts
raster and vector packages only; and without SPI usage
Sounds interesting, maybe I can cut down the geotrellis deps a bit more and do a minimal install
makes sense +
nice nested quotes
:D
Thanks again for the gudience, I'll let you know how i go

@jnh5y not with GraalVM but with its Native Image https://www.graalvm.org/reference-manual/native-image/Limitations/
I think JTS uses some reflection; but mb it will 'just work'
Hi I want to read the RDD by time. This is my code
val attributeStore = FileAttributeStore("/Users/xugaofeng/tif/LC08TIME/123")
val layerReader = FileLayerReader(attributeStore)
val queryResult: TileLayerRDD[SpaceTimeKey] = layerReader.query[SpaceTimeKey, Tile, TileLayerMetadata[SpaceTimeKey]](LayerId("TESTTIME", 2))
.where(Between(ZonedDateTime.of(2018, 12, 27, 7, 0, 0, 0, ZoneOffset.UTC), ZonedDateTime.of(2018, 12, 28, 9, 0, 0, 0, ZoneOffset.UTC)))
.result
val maximumTemperature: RDD[(SpatialKey, Tile)] = queryResult.map { case (key, tile) => (key.getComponent[SpatialKey], tile) }.reduceByKey(_.localMax(_))
val tile = maximumTemperature.stitch()
val png = tile.renderPng(colorMapPm25)
png.write("/Users/xugaofeng/tif/LC08TIME/123/time.png")Error message
