PDAL 1.6.0 packaged for Fedora including vertical datums and grids

Cologne city shown as colorized 3D point cloud (data source: openNRW Germany)In order to simplify the installation of the latest PDAL release (Point Data Abstraction Library, http://www.pdal.io/, version 1.6.0) on Fedora, I have created an updated set of RPM packages now including vertical datums and grids (.gtx files from here).

The installation is as simple as this (the repository is located at Fedora’s COPR):

# enable extra repos to satisfy dependencies
sudo dnf copr enable neteler/pdal-hexer
sudo dnf copr enable neteler/points2grid

# install dependencies
sudo dnf install hexer
sudo dnf install points2grid

# enable and install PDAL
sudo dnf copr enable neteler/pdal
sudo dnf install PDAL PDAL-devel PDAL-vdatums

# run PDAL:
pdal-config --version
pdal --help

Enjoy!

GRASS GIS 7.2.2 released

GRASS GIS 7.2.2 in action

What’s new in a nutshell

After three months of development the new update release GRASS GIS 7.2.2 is available. It provides more than 120 stability fixes and manual improvements compared to release version 7.2.1. An overview of new features in the 7.2 release series is available at New Features in GRASS GIS 7.2.

About GRASS GIS 7: Its graphical user interface supports the user to make complex GIS operations as simple as possible. The updated Python interface to the C library permits users to create new GRASS GIS-Python modules in a simple way while yet obtaining powerful and fast modules. Furthermore, the libraries were again significantly improved for speed and efficiency, along with support for huge files. A lot of effort has been invested to standardize parameter and flag names. Finally, GRASS GIS 7 comes with a series of new modules to analyse raster and vector data, along with a full temporal framework. For a detailed overview, see the list of new features. As a stable release series, 7.2.x enjoys long-term support.

Gaining more WMS speed through enabling the QGIS cache directory

Interestingly the WMS caching is not enabled by default in QGIS. To better enjoy WMS/WMS-C/WMTS connections – if you have some disk space to dedicate – it is a good idea to enable the cache in these few steps:

Go to the menu entry Settings >> Options:

Enabling the QGIS WMS cache - step 1

Enabling the QGIS WMS cache – step 1

Go to tab “Network“. Therein, in “Cache settings“, select the “Directory” and choose a folder for the cache files. Be sure that there is free space for lots of megabytes can be stored there over time. And this directory should ideally be located on a fast disk (if you have several).

Here I choose the existing “tmp/” folder in my HOME directory and create inside a new folder “qgis_wms_cache”:

Enabling the QGIS WMS cache - step 2

Enabling the QGIS WMS cache – step 2: create new “qgis_wms_cache” cache folder

Eventually we change the “Default expiration period for WMS-C/WMTS tiles (hours)” to more than 24 hours (as it would be rather useless…). Here I change to 24*30 = 720 hours. And the cache size we increase as well, here to 250MB (written as 250000 since it is to be given in kilobytes):

Enabling the QGIS WMS cache - step 3

Enabling the QGIS WMS cache – step 3: increase expiration period for tiles and cache size

Now we press “OK” and close the dialog. Time to try out a WMS service, zoom back and forth… and:
Enjoy!

New GRASS GIS 7.2.x stable release branch created

Towards the new stable release series

As of 24 May 2016, a new stable release branch was created for the upcoming GRASS GIS 7.2 release. This new branch includes all the many improvements which have been implemented in the former development version 7.1.svn.

What is a branch? In simple words, it is a kind of directory in the software development server (SVN in our case) in which no more development but only bugfixing happens. From a release branch, new stable releases are created and published.

The actual branches in the GRASS GIS project are:

  • very old stable: releasebranch_6_4 (used for bugfixing and to publish stable GRASS GIS 6.4.x releases) – very low release frequency (started in revision r34936)
  • old stable releasebranch_7_0 (used for bugfixing and to publish stable GRASS GIS 7.0.x releases) – perhaps one last release upcoming (branch started in revision r59487 but development already started in Apr 2008 in r31142)
  • new stable releasebranch_7_2 (used for bugfixing and to publish stable GRASS GIS 7.2.x releases) – upcoming series of stable releases (branch started in revision r68500)
  • trunk (used for development, with pseudo-name 7.3.svn) – under heavy development

Note to SVN users

The trunk branch with pseudo-name 7.1.svn has become 7.3.svn due to the creation of the new 7.2.svn release branch. You can simply continue to update from SVN, the version will be automatically updated.

If you used to work with the 7.0.svn release branch, consider to download the new 7.2.svn release branch, either from the weekly source code snapshot (here) or from the SVN server directly (here).
