Jackie Ng: vcpkg is very interesting too

OSGeo Planet - Tue, 2017-05-09 18:14
Part of what spurred my interest in gRPC was its ease of consumption on Windows through vcpkg allowing me to easily build and prototype some gRPC services and be able to easily interop from clients in different programming languages.

For those not in the know, vcpkg is Microsoft's attempt at a package manager for C/C++ libraries on Windows. This tool is pertinent to my interests because, look at what we currently keeping in our MapGuide/FDO source repos!

That's several GBs of source code for external thirdparty libraries we need to build MapGuide and FDO. It's a situation we can't avoid at the moment (especially on Windows) because until vcpkg, we had no choice. There was nothing akin to "nuget for C++ libraries" for Windows. On Linux we at least have the option of offloading to system installed libraries provided by the default distro package manager.

With vcpkg, this would greatly simplify the MapGuide/FDO build system on Windows. Most of the libraries listed here already exist as ports in vcpkg and most are more up-to-date as well. Imagine just doing a svn sparse checkout, skipping having to download whole parts of Oem/Thirdparty, point the MapGuide/FDO sources to our existing pre-built vcpkg packages and enjoy much faster build times, because we're not wasting a majority of it building external libraries. It may be even fast enough to continuously integrate!

It would also almost certainly spell the end of the difficult story around custom GDAL binaries as well, because I've been doing my part to add/enhance (geospatially-)relevant vcpkg ports and to light their current GDAL vcpkg port up with as many features as technically and legally possible. If we ever do get to building FDO using vcpkg-sourced external libraries, you're gonna get a GDAL/OGR provider with maximum vector/raster format support (barring the obvious omissions like Oracle, DWG, ECW, etc due to legal hurdles in obtaining and using their respective libraries and SDKs)

A vcpkg-based MapGuide/FDO build system for Windows is definitely something on my radar.

Jackie Ng: React-ing to the need for a modern MapGuide viewer (Part 16): It didn't have to be this complicated

OSGeo Planet - Tue, 2017-05-09 17:06
The major theme of the next release of mapguide-react-layout is to open up the floodgates to all sorts of viewer customizations.

In particular the next release will be my first foray into npm modules as I intend to publish this next release as one. The npm module allows for the following types of customizations:

  • Custom viewer layout templates
  • Custom viewer script commands
  • Being able to selectively include/exclude viewer features to reduce bundle size
These customization options will only be available through the npm module
One major roadblock that has appeared is that we currently include a verbatim copy of our Fusion PHP backend so that certain viewer commands will work:
  • Buffer
  • Query
  • Redline
  • Theme
  • Feature Information
  • QuickPlot
  • Search
How does this roadblock us? Well with this PHP backend bundled, the npm module story is more complicated:
  • It would involve some serious webpack (or some other post-build) shenanigans to get the backend PHP content deployed in the right place, relative to your custom viewer bundle.
  • It bloats the size of the npm module (based on my simulations using npm pack).
  • I feel extremely icky publishing a JavaScript library that bundles a PHP backend as a required dependency.
In hindsight, bundling a copy of this Fusion backend is totally not necessary. It is simpler to just make our viewer commands point and talk to the existing Fusion backend. When MapGuide is installed, Fusion and PHP will always be there, so this is a safe assumption to make. It's the same environmental assumption that allows for mapguide-rest to be an easy "drop into www" and it works.
By re-using the existing Fusion backend for these tools, there also another positive side effect. It means we have to also polyfill whatever Fusion viewer APIs are needed for the frontend HTML/JS content of these Fusion widgets to work within mapguide-react-layout without modifications. What this means is that migration should be even easier as we are now polyfilling various common Fusion viewer APIs in addition to the AJAX viewer APIs.
So with this next release, the viewer will now reuse the Fusion backend of your MapGuide installation. As a result, it also means the zip packages for this release will be much smaller as well.

Fernando Quadro: Introdução ao GeoGig – Parte 4

OSGeo Planet - Tue, 2017-05-09 12:58

Explorando os dados no QGIS

Você pode abrir qualquer uma dessas tabelas no QGIS para visualizá-las e explorá-las. Para fazer isso, basta arrastar e soltar o item da tabela correspondente na tela QGIS e uma nova camada será criada. Adicione a camada de edifícios (buildings).

Ela deve ser mostrada na tela QGIS em toda a sua extensão.

Para melhorar a visualização, você pode adicionar uma camada base. Um plugin muito útil é o plugin OpenLayers, o que simplifica bastante a adição de algumas das camadas base mais comuns, como Google, Bing ou OSM. Você pode instalá-lo abrindo o Gerenciador de Plug-in, selecionando a seção Obter mais e, em seguida, procurando por OpenLayers.

Agora no menu Plugins você deve ter uma nova entrada onde você pode selecionar as camadas para adicionar.

Abaixo você pode ver a camada de edifícios com a imagem aérea do Bing, ampliada sobre a cidade de Adis Ababa.

Você pode consultar os dados na camada PostGIS para saber mais sobre os edifícios que ele contém. Selecione a ferramenta de identificação indo para a entrada do menu Exibir / Identificar recursos. Agora selecione a camada edifícios clicando no nome na lista de camadas. Clique em qualquer um dos polígonos e uma caixa de diálogo como a mostrada abaixo aparecerá, contendo informações correspondentes a esse polígono.

A tabela completa de atributos para todos os recursos da camada pode ser mostrada clicando com o botão direito do mouse no nome da camada e selecionando Abrir Tabela de Atributos no menu de contexto.

From GIS to Remote Sensing: Webinar by NASA ARSET on Remote Sensing of Land Indicators for Sustainable Development Goal 15

OSGeo Planet - Tue, 2017-05-09 06:30
In 2016 the world leaders adopted the 17 Sustainable Development Goals (SDGs) of the 2030 Agenda for Sustainable Development, which is a United Nations initiative to achieve sustainable development (the only development that grants the needs of future generations).

In particular, the United Nations Sustainable Development Goal 15: Sustainably manage forests, combat desertification, halt and reverse land degradation, halt biodiversity loss. This goal has many targets by 2020 and 2030 in order to ensure the conservation of forests, ecosystems and their biodiversity, and combat desertification.
We should all be involved in achieving these targets of sustainability.

In this post I recommend to register to the upcoming free webinar by NASA ARSET (Applied Remote Sensing Training) focused on addressing the Sustainable Development Goal 15 through remote sensing and the calculation of land indicators, estimating forest area and forest change, including an introduction to image classification, change detection, and accuracy assessments.

GeoSolutions: New release of MapStore with improved map embedding

OSGeo Planet - Mon, 2017-05-08 15:00

Map Embed

Dear Reader,

we are pleased to announce a new release of MapStore 2, our flagship Open Source webgis product, which we have called 2017.03.00. The full list of changes for this release can be found here, but the latest most interesting additions are the following.

  • Improved Embed view
  • Full Screen option
  • Elevation Slider
Improved Embed view

This release gives you more options when embedding a map. You can now choose to embed with an IFrame or by using the new MapStore2 Javascript API.  The share tool now provides the two options with the code you can copy and paste in your site.

[caption id="attachment_3439" align="alignnone" width="400"]Share window now has more options Share window now has more options[/caption]

For the iFrame version you can choose if you want the table of content by checking the "Show TOC" option. For the API version, you have a full html page with the proper inclusion of css and javascript files.

Table of Content is optional inside IFrame

The table of content on the left side is now hidden by default so your users can focus on your data and have more room to view it. If you still want to display the TOC, you can add the “forceDrawer=true” parameter in the URL. Here is the result:

[caption id="attachment_3438" align="aligncenter" width="1024"]Iframe version VS JS Api version Iframe with and without TOC[/caption] Here a real map included. Page with API

In certain environments you really do not want to use an iFrame, but you would rather want to integrate the map as part of your application using a JavaScript API: you can now do it with the newly  created MapStore2 API. The Share window will now generate the html you can put in your page and leverage the MapStore2 API to load and configure the map.  Here is how it looks like:

[caption id="attachment_3440" align="alignnone" width="500"]A possible usage of the JS API in your page A possible usage of the JS API in your page[/caption]

You can also programmatically interact with the map using the Javascript API, listening for events.  You can learn what you can do with the JavaScript API by following the reference here.  You can find a sample application that uses the Javascript API here.

Full Screen Supoport The map can now be expanded to full screen size.  [caption id="attachment_3435" align="aligncenter" width="796"]Fullscreen switch Fullscreen switch[/caption] This is very useful for small devices where the screen space is small. Initial support for Elevation Dimension on WMS MapStore now detects if a layer has an elevation dimension and displays a new tab in the layer properties window. From the new tab you can choose the elevation to display. [caption id="attachment_3436" align="aligncenter" width="1134"]Elevation Slider in action Elevation Slider in action[/caption]

In the example you can see the values of the elevation/depth provided by the server in a chart. This widget guides the visualization by setting the values of the Elevation dimension for the layeryou are viewing.

Future Work

In the next release we will focus on bug fixes as well as user interface improvements, including also a fully integrated 3D Viewer for maps based on Cesium.

Cameron Shorter: Building an Open Government Multistakeholder Forum

OSGeo Planet - Sun, 2017-05-07 05:19
BackgroundThe Australian government's Department of Prime Minister and Cabinet is asking for community input on the development of an Open Government Multistakeholder Forum: a group that will allow government and the community to ensure the commitments of Australia’s Open Government National Action Plan are realised. The plan's commitments involve strengthening and improving:
  • Transparency and accountability in business,
  • The availability of open data and the digital transformation of government services,
  • Access to government information,
  • Integrity in the public sector, and
  • Public participation and engagement.
Framing the questionLet’s be more specific by defining the question this forum should aim to solve:
How can decision makers make good decisions about complex topics which address community needs and reflect community values, incorporating community engagement and earning community trust?Unfortunately, the utopian vision of open government has inconvenient practical limitations requiring a healthy dose of pragmatism in order to be effective. The following challenges exist:
  • How do you attract the attention and contributions from people, acknowledging that we are in an era of information overload and competing priorities?
  • How do you facilitate conversations about complex and intricate issues, acknowledging that it requires substantial time to fully understand and then debate concepts?
  • How can you assess comprehensive community opinion on complex subjects, acknowledging that most people don’t have time to engage in the study or debate.
  • How do you avoid inappropriate bias from vested interests, acknowledging that vocal minorities (companies or individuals) may promote self serving principles contrary to the interests of the majority?
  • How do you gain trust from communities in presented information?
  • How do you manage communication overhead from a large community, finding and promoting the best ideas? (Increasing the signal-to-noise ratio).
  • How can people with a good ideas know they will be heard, and hence be encouraged to participate, noting the best ideas for complex subjects will be time consuming to develop and express? (Increase voice-to-signal ratio).
  • How do you efficiently avoid conversations being derailed by inappropriate or disrespectful behaviour? (Don't feed the trolls)
Learn from Open SourceIn answering these questions we can learn from the communities behind established Open Source Software projects. Most of the principles behind Open Government are inherited from Open Source best practice, which in turn are based on morals found in gift economies such as family gatherings and local community groups.
Established Open Source communities typically have embraced Merit-ocracy, Do-ocracy, Reciprocity, Respect, Modularity, Pragmatism, Sustainable Practices, and have attracted Strategic Funding. Each of these points should be considered in detail as to how they should be applied in the Open Government context.
Open Source projects typically are started by a small volunteer base. All the team know each other intimately. Leaders organically evolve, based on meritocracy and do-ocracy. If the project successfully grows, it builds a technical base which becomes too big to maintain on volunteer labour alone. The project either hits a glass ceiling, or attracts external funding to resource core activities (such as project coordination). Australian Open Government has grown to a size comparable to large established Open Source projects and should be managed and resourced accordingly.
Answering Specific QuestionsGovernment have suggested a basis for founding an Open Government Multistakeholder Forum and asked for community input. Highlights include:
  • Purpose: [The scope of work described for forum members, covering review, building a reasoned opinion based upon analysis, debating and then explaining opinions as recommendations which would require a non-trivial amount of time for diligent members to complete properly.]
  • Ways of Working: The Forum [will] meet at least every two months, in a location rotated between capital cities.
  • Ways of Working: Forum members [will] not be remunerated, but that its community members be reimbursed by government for reasonable travel costs.
  • Structure: The Forum [will] comprise not more than 16 members ... with equal representation from government ... and the community.
  • Appointment Criteria:  The Forum [should] broadly reflect the [social] diversity of the Australian community. In particular ... women and men should hold at least 40 per cent of positions on the Forum. ...
Question 1: Are there any other functions the Forum should usefully perform?
Question 2: If you do not agree with the single forum model, how do you think another model should work?
Question 3: Are there other ways of working you think the Forum should usefully adopt?
Question 4: Are there any other criteria or guidelines that should inform the appointment of community members to the Forum?

Answers 1-4:
There is a significant mismatch between the apparent workload, the accountability that should exist, and the expectation that leadership should come from unfunded volunteers. This should challenge our underlying human morals and ethics.
  • For forum members to provide valuable leadership, they should allocate substantial time analysing, debating and deciding on issues. This would equate to multiple days per week, which is more than most volunteers have available to them. Note that you want to attract committed people already playing leadership roles in open project(s).
  • As well as being morally questionable, I'd expect that having the Australian government expect forum members to work for free is counter to Australian labour laws.
  • I would expect that nominated government employees would be paid to participate as part of their daily work. This will create a mismatch in effort and influence that can be applied by government employees verses community members.
  • If community members are instead paid to participate by an external employer, one should question likely conflicts of interest.
  • If continuing with unpaid forum membership, the scope of tasks expected of forum members should be reduced to be in line with typical capacity of volunteers. 
  • The "Purpose" for the Multistakeholder Forum should be accompanied by realistic time and task commitment expectations of forum members, such that candidates and the community have a clear understanding of what should be done.
  • As well as aiming for social diversity, the forum would benefit from having a multi-disciplinarian team. 
Question 5: How should a selection panel to recommend Forum appointments be composed?Question 6: Should nominations to the Forum be published?
Question 7: Having regard to the desirability to appoint Forum members without unnecessary delay, is there a better way to administer the nominations and appointment process?
  • If forum membership is treated as a paid position, then candidate selection should be treated with the same privacy applied to standard job hiring.
  • If membership is unpaid, then a public process could be considered. For instance, each candidate could provide a brief statement about themselves. The community can then vote on potential candidates to help short list candidates. The final selection should go to the selection committee who considers community votes when doing face-to-face interviews.
Question 8: Should appointments to the Forum be staggered?Question 9: How should any mid-term vacancies be filled?

  • More relevant is "How should the Forum be refreshed?" In order to ensure history from one panel to the next, only a maximum of half the panel should be updated in any election cycle.
Question 10: How can the Forum best hear and respond to the range of community perspectives on open government?
This question requires construction of a well thought out plan. Here are a few memory jolters (to be considered with comments above):
  • Define a clear vision and set of principles which casual members of the community can quickly assess and agree or disagree with.
  • Trace all actions back to these principles.
  • Acknowledge the diversity in your community's level of interest and time commitments and adjust accordingly. 
  • Make use of tools which efficiently capture crowd wisdom. Eg: Allow comments on posts, and allow communities to vote up/down comments based on merit.
  • Respect the time and value of your community. Treat them as partners rather than a survey point. Adopt tools and processes which enables the community to maximise each individual's value of each contribution.
Post NoteThis response is based on my background working within Open Source communities, Open Standards communities, activist communities and local communities. Do these ideas make sense to people with different experiences?

Free and Open Source GIS Ramblings: Report from the Essen dev meeting

OSGeo Planet - Sat, 2017-05-06 13:27

From 28th April to 1st May the QGIS project organized another successful developer meeting at the Linuxhotel in Essen, Germany. Here is a quick summary of the key topics I’ve been working on during these days.

New logo rollout

It’s time to get the QGIS 3 logo out there! We’ve started changing our social media profile pictures and Website headers to the new design: 

Resource sharing platform 

In QGIS 3, the resource sharing platform will be available by default – just like the plugin manager is today in QGIS 2. We are constantly looking for people to share their mapping resources with the community. During this developer meeting Paolo Cavallini and I added two more SVG collections:

Road sign SVGs by Bertrand Bouteilles & Roulex_45 (CC BY-SA 3.0)

SVGs by Yury Ryabov & Pavel Sergeev (CC-BY 3.0)

Unified Add Layer button

We also discussed the unified add layer dialog and are optimistic that it will make its way into 3.0. The required effort for a first version is currently being estimated by the developers at Boundless.


The new TimeManager version 2.4 fixes a couple of issues related to window resizing and display on HiDPI screens. Additionally, it now saves all label settings in the project file. This is the change log:

- Fixed #222: hide label if TimeManager is turned off - Fixed #156: copy parent style to interpolation layer - Fixed #109: save label settings in project - Fixed window resizing issues in label options gui - Fixed window resizing issues in video export gui - Fixed HiDPI issues with arch gui

The "United Nations Platform for Disaster Management and Emergency Response" (UN-SPIDER) is a United Nations program that aims to "ensure that all countries and international and regional organizations have access to and develop the capacity to use all types of space-based information to support the full disaster management cycle".
In particular, UN-SPIDER aims to ensure access and use of space technologies for humanitarian aid and emergency response, during all phases of the disaster management cycle.

The UN-SPIDER website provides several recommended practices for fostering the use of satellite data in the various phases of disaster management.
In this post I am glad to suggest this methodology for mapping burn severity in the disaster cycle phase of recovery and reconstruction.
