From jsanz at osgeo.org Mon Mar 2 02:21:45 2020 From: jsanz at osgeo.org (Jorge Sanz) Date: Mon, 2 Mar 2020 11:21:45 +0100 Subject: [OSGeo-Announce] PROJ 7.0.0 In-Reply-To: <5B487988-9EDB-4B06-940E-B73D92771BB6@sdfe.dk> References: <5B487988-9EDB-4B06-940E-B73D92771BB6@sdfe.dk> Message-ID: It is my pleasure to announce new releases of PROJ and related packages. The major feature in PROJ 7 is significantly improved handling of gridded models. This was implemented in RFC4 [0]. The main features of the RFC4 work is that PROJ now implements a new grid format, Geodetic TIFF grids, for exchaning gridded transformation models. In addition to the new grid format, PROJ can now also access grids online using a data store in the cloud. The grids that was previously available via the proj-datumgrid packages are now available in two places: 1. The new PROJ-data package 2. From the cloud via https://cdn.proj.org The PROJ-data package includes all grids and other resources previously tracked by the proj-datumgrid series of packages as well as some new grids. All grids in the PROJ-data package have been converted to the new Geodetic Tiff Grid (GTG) format introduced in PROJ with RFC4. The advantages of the GTG format are * Grids can contain more metadata than previous formats used by PROJ * Grids are compressed, taking up significantly less space * Cloud optimized, for easy on-the-fly access to grids online via https://cdn.proj.org/ * Advanced gridded models previously consisting of several files can now be contained in one file The data in the PROJ-data package is mirrored on https://cdn.proj.org/. A network-enabled PROJ build can leverage the CDN and retrieve (parts of) grids as specific transformations need them on the fly. PROJ-data can only be used with PROJ 7.0.0 and newer. Provided with PROJ is a utility called projsync that can be used download grids from the data store in the cloud. The use of the new grid format and the data from the cloud requires that PROJ is build against libtiff and libcurl. Both are optional dependencies to PROJ but it is highly encouraged that the software is build against both. PROJ 7.0.0 and the accompanying PROJ-data package can be download here: http://download.osgeo.org/proj/proj-7.0.0.tar.gz http://download.osgeo.org/proj/proj-7.0.0.zip http://download.osgeo.org/proj/proj-data-1.0.tar.gz http://download.osgeo.org/proj/proj-data-1.0.zip In addition the PROJ-data package the old proj-datumgrid series of packages has also been updated, to extend the life-time of the PROJ 6.x branch a bit longer. These will be the last updates to the proj-datumgrid packages. The Updated packages can be downloaded here: http://download.osgeo.org/proj/proj-datumgrid-europe-1.6.tar.gz http://download.osgeo.org/proj/proj-datumgrid-europe-1.6.zip http://download.osgeo.org/proj/proj-datumgrid-north-america-1.4.tar.gz http://download.osgeo.org/proj/proj-datumgrid-north-america-1.4.zip http://download.osgeo.org/proj/proj-datumgrid-oceania-1.2.tar.gz http://download.osgeo.org/proj/proj-datumgrid-oceania-1.2.zip ATTENTION: PROJ 7 will be last major release version that includes the proj_api.h header. The functionality in proj_api.h is deprecated and only supported in maintenance mode. It is inferior to the functionality provided by functions in the proj.h header and all projects still relying on proj_api.h are encouraged to migrate to the new API in proj.h. See https://proj.org/development/migration.html for more info on how to migrate from the old to the new API. [0] https://proj.org/community/rfc/rfc-4.html ??????????????????????????????????????

Message-ID: <42173c9f17d8fd17172fe331ccff771f@posteo.de> OSGeoLive archive is online! The OSGeoLive team has published an archive of all prior OSGeoLive docs, both online [1], and backed up in source control [2]. The archive provides an important historical record of geospatial development over the last decade. It contains all OSGeoLive documentation from 2.0 to the latest 13.0 version. The search continues for the 1.0 release! From memory, it didn't contain any docs. You are invited to travel into history to the beginning Version 2.0 [4] when OSGeoLive was called the "Arramagong Live DVD" and only contained 18 projects including GRASS GIS, Quantum QGIS, PostGIS, MapServer? and GeoServer?. A DVD was enthusiastically received by FOSS4G 2009 conference attendees in Sydney, Australia. Interesting facts Major version releases have aligned with the international conference for Free and Open Source Software (FOSS4G). In many years we also put out a minor release, to align with FOSS4G regional and local events. It is handed out at FOSS4G events and is used in many of the FOSS4G workshops. The theme of desktop backgrounds of major versions has been inspired by the location of the international FOSS4G conference, adopting a backdrop of the African savanna in Del es Salaam, and embracing the persona of Robin Hood in Nottingham. Why did we jump from 7.0 to 7.9 (instead of following convention and selecting 7.5)? It was to honour one of OSGeo's heros, Arnulf Christl, who also goes by the nickname of "seven-of-nine". OSGeoLive is very popular. Version 12.0 had 21,000 downloads and the latest version 13.0 has had 11,000 downloads 13.0 in the last 7 months. Source: [5] When packaging, we prioritise stability over cutting edge, quality over quantity, and end user experience over individual project needs. Software which has lost an active community have been retired and new projects added. Surprisingly, the number of projects on OSGeoLive has remained relatively static - hovering around 40 to 50. Seth Girvin came up with the idea of the archive and worked on it in 2019. It was a challenge to find older versions. Thanks a lot to Seth for the initiative. Thanks also to Cameron Shorter for the support, Angelos Tzozos for setting up the repo and Regina Obe from SAC for setting up the subdomain. I hope you enjoy the journey into the archive! About OSGeoLive OSGeoLive [3] is a ?Lubuntu based distribution of Geospatial Open Source Software, available via a Virtual Machine, USB, and Live DVD.

Ready to use binary packages are available on the package page of the website: OTB-7.1.0-Win32.zip for Windows 32 bits OTB-7.1.0-Win64.zip for Windows 64 bits OTB-7.1.0-Linux64.run for Linux OTB-7.1.0-Darwin64.run for Mac OS X You can also checkout the release branch with git: git clone https://gitlab.orfeo-toolbox.org/orfeotoolbox/otb.git OTB -b release-7.1 The documentation for OTB 7.1.0 can be found here The changes brought by this version include : - A new application FastNLMeans , an implementation of the NL Means smooting algorithm. The gaussian mode of the Smoothing application also have additionnal parameters (maxerror and maxwidth). - Applications with several output images (e.g. FineRegistration or DimensionalityReduction now support multi-writing: instead of computing and writing each image independently, the streamed image blocks are written in a synchronous way for each output, saving computation time. this behavior can be deactivated using the &multiwrite extended filename . - In Superbuild and binary packages, GDAL version has been upgraded to 3.0.2, PROJ version to 6.2.1, openjpeg to 2.3.0, geos to 3.6.1 and netcdf to 4.7.3. Support for openCV 2.X has been removed. This version also includes many bugfixes. The full changelog can be accessed here .
