QGIS Blog: Update on the QGIS Grant Applications

OSGeo Planet - Tue, 2017-04-04 09:32

In February this year, we put out a call for applications for the second (yay!) round of the QGIS grant programme. The intent of the programme is to leverage donor and sponsor funding in order to support community members with great ideas to improve the underlying infrastructure of the QGIS project and code base.

We have had a really great response to the call for applications (detailed list of applications is here for your reading pleasure – 231KB download).

Given that we have 13 proposals (down 7 from our last call) and only 20,000 Euros to disburse, the QGIS voting members will need to make some tough, pragmatic choices.The voting for the grant proposals ends at the mid April 2017, and we plan to announce the successful candidates soon after that. The PSC will arbitrate in the case of a dead heat or the proposal amounts of the top voted proposals not adding up to our funding target.

Although the number of proposals submitted is down from last year, the quality and utility of the proposals this year is really top notch and it is sad to know that we will not be able to fun them all through the grant programme. If you have the wherewithal to further support some of the grant proposals that did not make the cut, or the QGIS 3.0 effort in general, please get into contact with our treasurer, Andreas Neumann (finance [at] qgis.org) or head over to our sponsorship or donations page to support their work!

Lastly, I appeal to those QGIS Voting Members who have not yet cast their votes to check your email and head over to the voting form to cast your vote!

GIScussions: The next PSMA may reshape Ordnance Survey

OSGeo Planet - Mon, 2017-04-03 13:15

Just the water and me

This advert recruiting for a “Head of Public Sector Mapping & Addressing Agreements Team” reminded me that the current Public Sector Mapping Agreement (PSMA for OS geeks and followers) is coming up for renegotiation with a deadline of end 2017 (presumably the new renegotiated agreement will come into effect on 1st April 2018). This a 2 year contract at a fairly senior level:

We are looking for someone with strong commercials skills and ideally experience of contract management to join the team at a crucial time.

Over the next 12 months we will be renegotiating our large value contracts that enable the whole of the public sector to gain access to vital geo-spatial data from Ordnance Survey. The current agreements are worth over £75m per annum. 

This will be a complex and multi-layered contract negotiation. It is not just on behalf of BEIS, but on behalf of the whole community of public sector users in England and Wales including Government Departments, all Local Authorities, and the emergency services. This will also require close working Scottish Government to ensure that the agreement aligns with their arrangements with Ordnance Survey and allowing cross border use of data.

The post-holder will be required to make judgements on how far to accommodate a wide range of stakeholders’ priorities, some of which may be competing.

This could be a big deal for Ordnance Survey, their users and for the OpenData community. In 2015-16 Ordnance Survey were pretty flat in terms of revenue, full accounts are here and my summary of the last few years (re-organised to take account of changes in reporting) is here, the report says

It was a challenging year for revenue, which resulted in a small overall growth on the prior year, delivered under the Trading Fund − with OS sales to consumers being more buoyant.

Perhaps revenue has started to pick up in 2016-17 but given 5 years of flat revenues (3.4% higher in 2015-16 vs 2011-12) that seems unlikely. PSMA represents just over 50% of OS total revenues, now add in the One Scotland agreement which will be influenced by the PSMA negotiation and the impact is even greater.

OS has taken little, if any, of the pressure of austerity that other parts of the public sector have experienced since 2010. One can imagine a scenario in which BEIS seeks to reduce the cost of the PSMA by 10%, 20% or more over the next 7 year period, that would have a pretty dramatic impact on OS. A 10% reduction in the value of the PSMA would almost halve OS net profit and 20% would reduce them to breakeven, anything more would be unthinkable in terms of the damage it would do. Of course BEIS doesn’t want to break OS, the public sector needs OS data as a core data resource and would struggle to replace OS as a supplier, hence suggestions from me and others that OS should be the custodian of the data rather than the owner which would allow competition to maintain the data. It will take some outstanding negotiation on behalf of OS with their principal share holder and customer to avoid this renegotiation substantially reducing profitability. Perhaps the recent announcement of 70 redundancies at OS is the start of a process to adapt to the probability of lower income from the public sector.

As far as I know there is a separate funding arrangement for OS OpenData

OS Opendata products are funded as a result of a commercial agreement between Central Government and OS, for the licence for OS OpenData and for its on-going maintenance. The Government is committed to ensuring a sustainable business model for OS to maintain their high quality data that is recognised worldwide. (source)

It doesn’t look as if the OpenData license is included in the current negotiations but it could well be up for a renegotiation soon and that is likely to put further pressure on OS finances and activity in the OpenData arena.

What will be the impact if the renegotiation results in significant revenue reduction? I think we may see further slimming down of OS. Where senior management will prioritise economies (including the current round of redundancies) remains to be seen but I imagine that maintaining a focus on data quality and operations will mean sales and marketing to the public sector, education and outreach, research and support for innovation as part of OpenData could all come under pressure.

Life would be easier if non public sector revenues could be accelerated but this has been on the agenda for nearly a decade and the breakthrough has yet to materialise.

That illusive sale (or introduction of external investment) seems to be further away than ever, but then I did point out some of the difficulties to the previous Chancellor of the Exchequer in 2015!

gvSIG Team: Reprojection with transformation has been fixed for gvSIG 2.3.1

OSGeo Planet - Mon, 2017-04-03 12:42

GDAL was included in gvSIG 2.3.1 version as library for raster information accessing and projections, which added new formats to be loaded in gvSIG too, both vector and raster ones. Including this library for projections, the reprojection using transformation, including grids stopped working.

This problem has been fixed already through a plugin that can be installed on this version.

For that you have to follow these steps:

  • Access to the Add-ons manager (from the Tools menu).
  • Mark the “Installation from URL” option.
  • Select “Testing gvSIG repository – http://downloads.gvsig.org/download/gvsig-desktop-testing/” server and press “Next”.
  • At the list of add-ons we will look for “CRS: CRS management (GDAL/Geotools based, Native)”, build 2.1.60-2115. We will mark it and we press “Next”.

  • We will press “Start download” and once it’s downloaded we press “Finish”.
  • Finally we restart gvSIG and it will be available.

At this way we will be able to reproject our layers using transformations, applying grids too.

gvSIG Team: Reproyección con transformación corregida en gvSIG 2.3.1

OSGeo Planet - Mon, 2017-04-03 12:30

En la versión 2.3.1 de gvSIG se incluyó GDAL como librería de acceso a información ráster y proyecciones, lo que añadió también nuevos formatos que podían cargarse en gvSIG, tanto vectoriales cómo ráster. Al incluir esta librería para proyecciones se dejaron de soportar las reproyecciones con transformación, incluyendo las transformaciones con rejilla.

Este problema ha sido solucionado, y ya hay un plugin disponible para instalar sobre esta versión que corrige el problema.

Para ello se deben seguir los siguientes pasos:

  • Acceder al Administrador de complementos (en el menú Herramientas).
  • Marcar la opción de “Instalación por URL“.
  • Seleccionar el servidor “Testing gvSIG repository – http://downloads.gvsig.org/download/gvsig-desktop-testing/” y darle a “Siguiente”.
  • En el listado de complementos buscaremos “CRS: CRS management (GDAL/Geotools based, Native)”, build 2.1.60-2115. Lo marcaremos y le daremos a “Siguiente”.

  • Le daremos a “Comenzar descarga” y una vez descargado pincharemos en “Terminar”.
  • Finalmente reiniciamos gvSIG y ya lo tendremos disponible.

De esta forma podremos reproyectar nuestras capas con transformación, aplicando incluso rejilla.

Entre otras cosas, podremos reproyectar las capas de ED50 (sistema oficial de España hasta hace un tiempo) a ETRS89 (sistema oficial actual) utilizando la rejilla ofrecida por el Instituto Geográfico Nacional.

Fernando Quadro: Introdução ao GeoGig – Parte 3

OSGeo Planet - Mon, 2017-04-03 12:15

Preparando e importando os dados

O arquivo de dados zip contém vários shapefiles que podemos importar para o banco de dados PostGIS que acabamos de criar. Podemos usar QGIS para fazer a importação.

Inicie o QGIS e certifique-se de que o navegador do mesmo está visível, ativando-o no menu Exibir/Painéis. Ele deve aparecer por padrão no lado esquerdo da janela do seu QGIS.

Abra o OpenGeo Explorer, que deve aparecer no lado direito da sua janela do QGIS.

Agora defina uma conexão com o banco de dados PostGIS. Clique com o botão direito do mouse em “PostGIS Connections” no navegador, e selecione Nova conexão. Preencha a tela como mostrado abaixo.

Use geogig como password. Se você estiver executando um PostGIS padrão ao invés do OpenGeo Suite, sua porta será provavelmente a 5432 senão será a 54321.

A conexão do PostGIS (PostGIS Connections) deve ser atualizada e preenchida com as conexões atuais definidas no QGIS, entre elas a que você acabou de criar.

Você pode importar camadas simplesmente arrastando e soltando os arquivos correspondentes do navegador e no item de conexão no OpenGeo Explorer (você também pode soltá-los no item PostGIS no navegador QGIS, mas isso não é tão prático e não vai dar a você a opção de importar como geometrias individuais, o que é importante neste caso para alguns dos trabalhos que vamos fazer mais tarde).

Selecione todos os shapefiles do conjunto de dados da amostra e solte-os na conexão que definimos.

Uma caixa de diálogo será mostrada para configurar alguns parâmetros antes da importação. Certifique-se de configurá-los como mostrado na figura abaixo.

É importante marcar a caixa de seleção “Importar como geometrias individuais”, pois, como dissemos, isso será necessário para nosso trabalho posterior.

Clique em OK e os arquivos serão importados, criando uma tabela separada para cada um deles.

gvSIG Team: Vídeo-tutorial para aprender Georreferenciación con gvSIG Desktop

OSGeo Planet - Wed, 2017-03-29 09:39

La georreferenciación es un aspecto fundamental en el análisis de datos espaciales, pues nos indica la correcta localización de la información a analizar. Por georreferenciación entendemos la técnica de posicionamiento espacial de una entidad en una localización geográfica única y bien definida en un sistema de coordenadas y datum específicos. En un Sistema de Información Geográfica la herramienta de georreferenciación se aplica a información ráster (imágenes) sin coordenadas que requieren ser posicionadas adecuadamente, utilizando para ello una serie de puntos de control (puntos de coordenadas conocidas).

Dentro de la serie de webinars realizados en el marco de la colaboración con la Universidad Miguel Hernández hoy os presentamos el que os permitirá aprender a georreferenciar con gvSIG.

Fernando Quadro: Conheça o OpenStreetCam

OSGeo Planet - Mon, 2017-03-27 13:54

OpenStreetCam (originalmente chamado de OpenStreetView) é um projeto cujo objetivo é criar um grande banco de dados aberto com fotografias de ruas. Fotos georreferenciadas podem ser colocadas no sistema por qualquer um que abra uma conta de usuário.

Todos as fotos são supervisionadas por um certo número de pessoas (normalmente 3) para que se garanta que são adequadas ao projeto. Uma vez que uma foto tenha sido surpervisionada, ela torna-se disponível para as consultas da API e aparece no site para qualquer um vê-la, autenticado ou não. Em apenas 4 meses, a comunidade contribuiu com quase 12 milhões de imagens cobrindo 322 mil quilômetros.

O rápido crescimento do projeto atraiu a atenção do Google, que detém a marca registrada Street View. Eles demonstraram interesse ​​no OpenStreetView, mas também expressaram preocupações sobre o nome poder criar confusão, e depois de considerar os prós e contras com cuidado, foi decidido então mudar o nome do projeto para OpenStreetCam.

Se você ainda não experimentou o OpenStreetCam, por que não baixar os aplicativos gratuitos e abertos para Android ou iOS, e começar a contribuir com esse projeto?
