@pomadchin
not really. usually you don’t need all the dimensions to be loaded into memory and not everything at once
Frederic Guiet
@fguiet
single array for the entire las file!!!
Grigory
@pomadchin
it is doable and we would be happy to work on it once it would be required for someone
Frederic Guiet
@fguiet
u usre?
Grigory
@pomadchin
Well yes, Im sure - because I was the one who worked on all the PDAL / jni interfaces and geotrellis-pointcloud itself
Frederic Guiet
@fguiet
yeah but are you sure it is the good implementation
as a las file can contain billion of point
Grigory
@pomadchin
em; I didnt tell that it is a good implementation
it is a naive implementation
Frederic Guiet
@fguiet
:)
anyway, will try to chunk my las file
Grigory
@pomadchin
or you can create a PR and fix the way spark loads pointclouds into memory ;)
Frederic Guiet
@fguiet
so I can load it X,Y,Z values into a big hive table
Grigory
@pomadchin
Also, if you have only x,y,z you can filter the file by dimensions
Frederic Guiet
@fguiet
I will make a PR if I was smarter enough for sure
no the cas thought
case
not
:(

@pomadchin hi,which hbase version is required in gt3.0.0;hbase 1.3.1 is ok?
Grigory
@pomadchin
Hey @rexuexiangbei nope, we are on hbase 2.2 but you can try, API can be compatible

hello @pomadchin What is the use of this class?
Grigory
@pomadchin
Hey @15952026052 it is a zoomed layout scheme (as I already mentioned according to tms tiling scheme) - allows to derive zoom level based not the raster extent and the cellSize; also allows to derive layoutDefinjtion and derive it for some specific zoom level
Frank Dekervel
@kervel
hello, maybe stupid question, i'm trying to create the trivial PR suggested by @pomadchin and i'd like to test it on my project. now i have geotrellis/ and myproject/ but myproject refers to the released version of geotrellis in its build.sbt. how can i make my project using the geotrellis i built myself ?
Frank Dekervel
@kervel
i now did it with "sbt publishLocal" and then i changed version of geotrellis to 3.1.0-snapshot in my build.sbt but there must be a better way ?
Grigory
@pomadchin
Hey @kervel ; nope, you can use https://github.com/locationtech/geotrellis/blob/master/scripts/publish-local.sh if you have difficulties. The good part of the story that you usually need to publish everything once and after that you can just rebuild the project you modified
Frank Dekervel
@kervel
ah, the push creates symlinks ?
Grigory
@pomadchin
symlinks? ah sowe had difficulties with publishing everything through a single sbt commands (memory / etc). sowe created a seaparate script that publishes everything into a local maven repository

I've just come back to using geotrellis/vector after not touching it since 2.10, and I thought I would bring everything up to date with 3.1.0. Is that a good idea? Is there a good summary of changes somewhere? Feels like everything is miles from where it was.
Grigory
@pomadchin

hey @jamescosford you can get a high order summary from here: https://www.azavea.com/blog/2019/10/29/geotrellis-3-0-release/ also we have some release notes https://github.com/locationtech/geotrellis/releases/tag/v3.0.0 and we don’t have updated docs

the difference between 3.0 and 3.1 in a broken types hierarchy that was fixed in 3.1 and you probably won’t even notice it

James Cosford
@jamescosford
Thanks! I was stupidly looking at the master changelog and not the 3.0 branch changelog
I think I'm running into mostly locationtech/geotrellis#2932 stuff because I am using lots of JTS functionality
All of that high-overhead Scala wrapper stuff was really handy :D
Grigory
@pomadchin
yea; but we have some thin wrappers now around it; it was a reall mess always to convert between jts and our vector types :D
James Cosford
@jamescosford
I'm sure I will appreciate the improvements once I get rid of all these red squiggles. Thanks for the help, and all the hard work you guys have been doing.

I'm trying to produce a visual representation of a GeoTIFF that contains elevation data (or other dimensions, but elevation is a good example: something along the lines of the kind of visual illustration shown at the top of this page: https://library.carleton.ca/help/dem-formats). The raw underlying data does not naturally translate into a useful color range (or even grayscale) for rendering on the screen. I'm assuming I need to use a custom colorramp to make this work, but I'm a little lost as to where to begin. Anyone familiar with this sort of application and where I might learn more about how to get started?
Nathan Banek
@natonic77
Didn't exactly answer my own question about visualizing elevation data, but got closer. I used the built in ColorRamps in the library and got some decent results, but strangely I got different results for the same ColorRamp used with renderPng vs using it with renderJpg (renderJpg tended to be more muted than renderPng). Any idea why that would be?
Frank Dekervel
@kervel
is the rasterizer in geotrellis (geotrellis.raster.rasterize) elaborate enough to use as a simple tile renderer for vector data in postgis ? (there are tons of other options, but since i'm already using geotrellis ..)
Grigory
@pomadchin
@kervel I think it would work; @MahdiSMIDA did smth like that and visualized pointclouds using it https://gitter.im/geotrellis/geotrellis?at=5d95c2113220922ffb1e776d

@metasim
@jamesmcclain are you still the lead guy on gdal_warp_bindings?
(about linkage rules on MacOS)
Grigory
@pomadchin
@metasim yep he is our lead guy here
:D
ha; interesting; so it assumes some to see some static paths?
