Hi Team,
We would like to add the project Cesium to the OSGeoLive Disk. We have
answered all the questions which are needed as per the link
<http://wiki.osgeo.org/wiki/Live_GIS_Disc_Apply>. I am in the process of
writing a script to get Cesium installed on a debian machine which I will
share once it is done. I will also put together a project overview and a
quick start guide.
Let me and Patrick know if we are missing something.
- Please describe your application.
- What is its name?
- Cesium
- What is the home page URL?
- http://cesiumjs.org/
- Which OSI approved Open Source Licence is used?
- Apache 2.0 license
- What does the application do and how does it add value to the
GeoSpatial stack of software?
- Cesium is a JavaScript library for creating 3D globes and 2D maps
in a web browser without a plugin. It uses WebGL for hardware-accelerated
graphics, and is cross-platform, cross-browser, and tuned for
dynamic-data
visualization. Cesium is open source under the Apache 2.0 license. It is
free for commercial and non-commercial use.
- Does the application make use of OGC standards? Which versions of
the standards? Client or server? You may wish to add comments about how
standards are used.
- WMS and WMTS. KML is expected in early 2015.
- What language is it written in?
- JavaScript
- Which version of the application should be included in the next
OSGeo-Live release?
- Version 1.4 http://cesiumjs.org/downloads.html
- Stability is very important to us on OSGeo-Live. If a new user finds a
bug in one application, it will tarnish the reputation of all other
OSGeo-Live applications as well. (We pay most attention to the following
answers):
- If risk adverse organisations have deployed your application into
production, it would imply that these organisations have verified the
stability of your software. Has the application been rolled out to
production into risk (ideally risk adverse) organisations? Please mention
some of these organisations?
- Cesium is widely used in government agencies and has been used in
NORAD Tracks Santa since 2012, which receives about 20 million unique
visitors each December.
- Open HUB <https://www.openhub.net/> provides metrics to help assess
the health of a project. Eg:
http://adhoc.osgeo.osuosl.org/livedvd/docs/en/metrics.html Could you
please ensure that your project is registered with Open HUB, and Open HUB
has been updated to reference the correct code repository(s) for your
project. What is the Open HUB URL for your project?
- https://www.openhub.net/p/cesiumjs
- What is the size of the user community? You can often answer this
by mentioning downloads, or describing a healthy, busy email list?
- The forum receives 250-300 posts per month, and rising.
- What is the size of your developer community?
- There have been 40 total contributors with about five currently very
active. See
https://github.com/AnalyticalGraphicsInc/cesium/blob/master/CONTRIBUTORS.md
- Do you have a bug free, stable release?
- The latest version 1.4
- Please discuss the level of testing that your project has gone
through.
- Cesium has 82K lines of runtime code and 78K lines of unit tests
with 93% code coverage.
- How long has the project has had mature code.
- Cesium 1.0 was released on August 1, 2014.
- OSGeo-Live is targeted at applications that people can use rather than
libraries. Does the application have a user interface (possibly a command
line interface) that a user can interact with? (We do make an exception for
Incubated OSGeo Libraries, and will include Project Overviews for these
libraries, even if they don't have a user interface.)
- Here we write JavaScript to be rendered on the browser.
- We give preference to OSGeo Incubated Projects, or Projects which are
presented at FOSS4G <http://foss4g.org> conferences. If your project is
involved in OSGeo Incubation, or has been selected to be presented at
FOSS4G, then please mention it.
- We presented at FOSS4G 2014 and FOSS4G NA 2013. We were also selected
to present at FOSS4G NA 2015.
- See http://cesiumjs.org/publications.html
- With around 50 applications installed on OSGeo-Live, us core packagers
do not have the time to liaise with every single project email list for
each OSGeo-Live release. So we require a volunteer (or two) to take
responsibility for liaising between OSGeo-Live and the project's
communities. This volunteer will be responsible for ensuring the install
scripts and English documentation are updated by someone for each
OSGeo-Live release. Also test that the installed application and Quickstart
documentation works as expected on release candidate releases of
OSGeo-Live. Who will act as the project's liaison person.
- Balasubramaniam Natarajan and Patrick Cozzi.
- OSGeo-Live is Ubuntu Linux based. Our installation preference is:
1. Install from UbuntuGIS or DebianGIS
2. Install .deb files from a PPA
3. Write a custom install script
Can you please discuss how your application will be installed.
We plan to do it with custom install script.
- OSGeo-Live is memory and disk constrained. Can the application run in
512 Meg of RAM?
- (We will get back on this point). In my test I ran Cesium on a gui
less virtualbox guest and accessed it from another computer via browser
which had capability for rendering WebGL on browser and it worked fine.
- How much disk space will be required to install the application and a
suitable example application?
- Less than a 100 MB, I am really overstating this it could be even
under 50MB.
- We aim to reduce disk space by having all applications make use of a
common dataset. We encourage applications to make use of the example
datasets already installed:
http://wiki.osgeo.org/wiki/Live_GIS_Add_Project#Example_Datasets If another
dataset would be more appropriate, please discuss here. Is it appropriate,
to remove existing demo datasets which may already be included in the
standard release.
- Each OSGeo-Live application requires a Project Overview available
under a CC By <http://creativecommons.org/licenses/by/3.0/> and a
Quickstart available under a CC By-SA
<http://creativecommons.org/licenses/by-sa/3.0/> license. (You may
release under a second license as well). Will you produce this?
- We will produce a project overview and a quick start guide.
- In past releases, we have included Windows and Mac installers for some
applications. It is likely we won't have space for these in future
releases. However, if there is room, would you be wishing to include
Windows and/or Mac installers?
- Not applicable for our project as it runs on the browser.
