In February, at the Toronto Code Sprint, the PostGIS team looked each other in the eye (for the first time) and committed to get the 1.4 release out by late April.
There is a common online question about migrating from Apple's Mail app (Using .emlx format mail files) to Thunderbird (or any other non-Mail app). I looked at a few options and have decided, as strange as it may seem, that installing an IMAP service was the best solution.
If you want to use GeoExt widgets BaseLayerContainer and OverlayLayerContainer in the same tree, like this:
GeoExt BaseLayerContainer and OverlayLayerContainer
var layerRoot = new Ext.tree.TreeNode({
text: "All Layers",
expanded: true
});
layerRoot.appendChild(new GeoExt.tree.BaseLayerContainer({
text: "Base Layers",
map: map,
expanded: true
}));
layerRoot.appendChild(new GeoExt.tree.OverlayLayerContainer({
text: "Overlays",
map: map,
expanded: true
}));
var layerTree = new Ext.tree.TreePanel({
title: "Map Layers",
root: layerRoot,
enableDD: true,
collapsible: true,
height: 200,
expanded: true
});
GeoExt is now at 0.5RC1 and it is rather good!
Nous organisons un séminaire gratuit sur le web pour parler de l’interopérabilité de la plate forme géospatiale Autodesk.
Au menu, FDO, Oracle, ArcGIS Server (ArcSDE), SHP, MapInfo, et comment les outils Autodesk permettent une utilisation directe de ces données, sans copie ni conversion. Nous présenterons notamment ce type d’utilisation dans un contexte web.
Si le sujet vous intéresse, que vous disposez d’une connexion Internet et êtes disponibles pendant une heure le vendredi 10 juillet, n’hésitez pas à vous inscrire.
I miei siti di ispirazione di web-mapping sono diversi. Nella mia top five c’è sicuramente EveryBlock, perché unisce leggibilità, efficacia, eleganza e attenzione alle buone pratiche (non soltanto dal punto di vista tecnologico).
Risponde ad una domanda “necessaria”: cosa avviene attorno a me?
Sono raccolte essenzialmente tre tipi di notizie:
E’ un servizio disponibile soltanto per alcune città degli Stati Uniti. Questo ad esempio l’URL per New York: http://nyc.everyblock.com/
L’interfaccia è raffinata e semplice allo stesso tempo, ed è notevole il numero di informazioni che trovate raccolte. Qui una lista di quelle del quartiere “DUMBO - Vinegar Hill - Downtown Brooklyn - Boerum Hill”.
Di ciascuno di questi report è possibile averne una visualizzazione cartografica e molto spesso anche un grafico che illustra l’andamento della variabile in oggetto (ad esempio la richiesta di rimozioni di graffiti!). Le città sono esplorabili per quartieri e per CAP.
Da oggi il codice che sta dietro EveryBlock è rilasciato in opensource, e già sogno di vederlo in azione per realtà a noi più vicine. Questo è quello che ci troverete dentro:
The main package (probably the thing you’re looking for) is the publishing system, known as ebpub.
Second, the packages ebdata and ebgeo contain Python modules for processing data and making maps.
Third, the packages ebinternal and everyblock round out the code that powers EveryBlock.com. They’re internal tools and are likely not of general use, but we’re including them to be complete.
Finally, ebblog and ebwiki are our blog and wiki software, respectively. Because, dammit, the world needs another Django-powered blogging tool.
Il codice è scritto Python sfruttando il framework web Django. Mi piacerebbe potermici sporcare le mani, ma in Python non vado oltre la dichiarazione di una variabile.

Has anyone ever run a service discovery and orchestration scenario like the one on page 7 of this document in any setting other than a demo? How far away from being able to do this in “real life” are we?
Well over a month ago I went over to the Bay area for Where2.0 and Wherecamp 2009.
Presented at the Ignite Where on the Thursday evening, after the workshops, about Map Warper.
Map Warper Ignite Slides on slideshare.
I’m near the end at 34:15 minutes in.
In fact, http://where.blip.tv is where to go for all the presentations.
Ignite format was fun, the lights were quite bright on stage so it appeared that I was scowling!
Scowling, and not from slagging off the Ordnance Survey too. Rather I think the OS deserves the love that it’s maps generate – it’s the people who use them that deserve the criticism.
I gave the example of an anti-pattern used in local governments in the UK:
As a response to this, and knowing that all the councils probably had digital collections of (unrectified) out of copyright maps, I am proposing “Free our Old Maps” project.
Lets use crowd sourcing techiques to free these old maps get layers and layers of old historical maps for the UK.
–
The rest of the conference was good.
Michal Migurski had a nice slot entitled “Flea Market Mapping” where he showed off his own attempts at a map warper, but was mainly highlighting the love of old maps. He was unaware of and didn’t see Map Warper or my talk before at the very same conference! (But liked it when he did see it later)
Wearabale Haptics talk captured my imagination.
The horizonless map from Autodesk was v. cool too. Can’t find the relevant link though…
Ugotrade writes up a nice review: http://www.ugotrade.com/2009/06/02/location-becomes-oxygen-at-where-20-wherecamp/
OpenStreetMap was a given, no longer a new thing that people didnt know about, it was pretty much mentioned casually throughout. The Stamen fellas did a nice workshop with mapnik, cascadenik and OSM data, which was very well attended.
Also over from Leeds was my buddy Mohsin, fresh out of Leeds Met, and presenting at Wherefaire his Snapture project. Using Leodis images, location on a mobile app, we can view Leeds through time. V. cool project.
Celý svůj krátký (ale prodlužuje se nám to) život jsem si říkal, že bych si rád někdy zkusil královskou vytrvalostní disciplínu - triatlon. Když se ségra odstěhovala na Dobříš a začala navštěvovat akce klubu Vlaška, začala mě na akce lákat taky. Zahájil jsem tím, že jsem asi 2 měsíce po chemoterapii zúročil zbytky tréningu na pražský marathon (běžel se v době, kdy do mě řezali Na Františku) a zaběhnul půlmarathon. Atmosféra závodu mě nadchla, prostředí také a když jsem k narozeninám od sestry a Karla dostal startovné na všechny závody, které pojedu, Dobříšský Tvrďák se vysloveně nabízel. Hned po Malevilu druhá akce.
V březnu v Roudnci otevřeli bazén a já navázal na zimní přípravu - běhání na Říp s Chlupem - plaváním. Zvedalo se to docela rychle a za dva měsíce jsem plaval víc, než kdy před tím. Občas jsem se dostal na kolo a trénoval jsem výjezdy na Říp (resp. kroužil jsem okolo kopce a občas na něj vyjel). Oproti Malevilu byla cyklistická příprava trochu méně intenzivní, ale rozhodně systematičtější. Pro jistotu jsem si šel po plavání nebo po kole ještě zaběhat s Chlupem. Říkal jsem si, že víc pro přípravu nemůžu udělat. Poslední tréning v úterý (jenom silnice a běh, bylo těsně po dešti) a rozhodnul jsem se, že do pátku musím zregenerovat.
Cestou na Dobříš jsem se stavil na Suchdole v cyklu Adam a koupil jsem si zcela nové cyklistické botky s pevnou podrážkou. Dorazil jsem na Dobříš, nechal kolo u ségry, namontoval jsem si špunty na svoje nové botky a prošel jsem se v nich v obýváku. Konstatoval jsem, že to nějak půjde a šel jsem spát k tetě kousek za Dobříš.
Ráno jsme se sešli ještě s Karlovým šéfem a jeho dcerou. Oba mají dohromady asi tolik co já sám (tedy váhu) a musí celý závod jet na tubu s cukrem, protože si nedovedu představit, odkud jinak tu energii berou. Mája je spolu s Adélou vítězka závodu Brdman Cross, Míla odjel dlouhej (100km) Malevil - zkrátka zkušení borci.
Pomalovali nás čísly, zaparkovali jsme kola, počasí nám přálo. Se ségrou jsem se ani nerozloučil - holky startovali o 15 minut před námi. Dohodli jsme se ale už dřív, že jak doběhnu, hned se jí vydám na pomoc - na půlmarathonu jsem doběhl dost napřed, na Malevilu jsem dojel snad o hodinu dřív - to nebude problém. Výstřel startovní pistole a holky huply do Papeže a hnaly se kolem dvou bójek a zpátky. Mája se vynořila z vody asi 4, Áďa asi 7 a vyrazily na kolo. Bezprostředně potom jsme startovali my.
Adélka leze z vody
Na vodu jsem si hodně věřil. Jednak jsem dost trénoval a jednak Majk zkrátil trasu na 500m. Ale když jsem viděl borce v neoprénech, jak se štosujou do první řady, stáhnul jsem se do zadní. To byla chyba, protože jsem až po první bójku nemohl proplavat přes hradbu těl, nakonec se ale podařilo a já plaval - oproti svému předsevzetí, totiž šetřit síly - jako o život. Voda měla prý asi 17°C, ale mě přišla v pohodě. Vynořil jsem se z vody ve velice slušném čase - i s převlečením asi 9 minut a vyrazil ke kolu, provedl striptýz, a vystřelil směr kopec Kazatelna.
Jaja leze z vody
Oproti Malevilu jsem nedostal křeč až na 30km, ale už na 3km - hned na prvním kopci - Kazatelně. Naštěstí jsem měl preparátek od ségry, nějak jsem se vyškrábal nahoru, nepoblil jsem se (ale moc nechybělo) mezitím mě všichni předjeli a pokračoval jsem dál. Na 10 km mě dojel Míla a pak už jsme jeli spolu až do cíle. Cestou jsme si občas povídali, ale postupně jsem na to musel šlapat víc a víc, abych mu stačil. Kromě jednoho pádu (mého) nám cesta ubíhala celkem bez zádrhelů. Míla říkal, že má za letošek naběháno už 6 kilometrů, říkal jsem si - s přihlédnutím k jeho věku a mému dosavadnímu tréningu - že to bude v pohodě. Furt jsme si říkali, kdeže ty holky jsou…
Jaja na kole
Když jsme dojeli, Míla se sebral a po asi půl kilometru mi utek’. A mě začalo osmi kilometrové trápení, kdy jsem si přiznal, že jsem fakt prostě nemoh’. Alespoň jsem pomohl kolegovi s křečema, protože jsem měl ještě tabletku a jemu asi pomohla. Ještě jsem se v závěru zmohl na finiš, kterým jsem předběhl asi 4 lidi (náhoda) a posunul se tak na kulaté 60 místo asi z devadesáti účastníků v mé kategorii. Ségra už v cíli byla - sedmá. Nejlepší nakonec: byl jsem asi o 9 minut rychlejší (což na skoro 2 a půl hodině není moc), ale v běhu mě vzala o 2 minuty! :-)
Maja běží
Míla běží
Kája běží
Celkové zhodnocení akce 0,5k-30k-8k tedy velmi dobré: Teplo ale ne vedro, vlhko ale ne rozbláceno, jeden pád a všichni dojeli. Největší respekt jde Ádě a Karlovi. A já holt budu muset ještě potrénovat. A velký dík Majkovi za skvělou organizaci!

The new Federal IT Dash board is available. This is one of the first initatives of Vivek Kundra the new Federal CIO.
NASA and the Japanese Ministry of Economy, Trade, and Industry (METI) have released the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) global digital elevation model (DEM), which covers about 99% of the Earth's surface. The global DEM was built from 1.5 million individual scene-based ASTER DEMs. The global DEM is in GeoTIFF format with lat/long coordinates and a 1 arc-second (30 m) grid. It is referenced to the WGS84/EGM96 geoid. Accuracy is estimated to be 20 meters for elevations and 30 meters for horizontal data.
The ASTER GDEM covers land surfaces between 83°N and 83°S and is comprised of 22,600 1°-by-1° tiles. Tiles that contain at least 0.01% land area are included.
I've just got back from a trip to the UK and Italy last week for the OSGIS event and the OSGeo Hacking Event. It was a great time of connecting with so many people that it exceeded my expectations.
Before heading up to Nottingham I was able to meet up with Martin Daly from Cadcorp (a GDAL/OGR sponsor) in London. We hadn't met face to face before, so I was glad to get a firsthand chance to see their SIS GIS Desktop product in action. Our very own Mateusz also works there so it was treat to catch up with him as well. Of course he couldn't resist going to Nottingham too and overworking his camera - his flickr feed is always helpful after an event :)
From the word go, Suchith Anand, Mike Jackson and the rest of the University of Nottingham's Centre for Geospatial Science crew had us hopping. I didn't realise it was possible to pack so much into a single day event! Thank you for the opportunity to deliver a keynote there and for lining up so many good speakers and people to meet with the following day as well. Three cheers! I'm sure next year will be even better.
It was a truly international event with close to 20 different countries represented. It was really good to catch up with many of you from all over Europe, I'll be going through my notes this week, but still feel free to drop me if you remember anything in particular we should pursue together.
One recurring theme of interest from several groups and and individuals, was the interest to partner with OSGeo to write case studies relating to their domain. I'm really looking forward to following up on these. If you want to help write, please let me know.
The OSGeo UK Chapter held a meeting as well, with Jo Cook leading the charge. It's always fascinating to see how different each chapter is - each with their own interests, strengths and local challenges. This was only the second time they met...sort of. Last year there were less than a dozen who met up to discuss the idea of forming a chapter. This year it was more like 50 or more people with broad interest from around the UK. Coming from a Canadian, it might seem strange to say that the UK chapter is spread out over large distances, but it is large enough that some more regional local groups are likely to pop up. There were contingents from Scotland and Wales talking about meeting and I know there are some Irish interested as well.
They have high hopes, so if you are the UK, join their list and find a good reason to get together and chat.

So I just finished attending my first Reboot – and as many people tried to explain before hand, “it’s weird”. Not just European Conference weird with completely different crowd, most attendees speaking in a foreign language (their own, or in English which is foreign to them), varying minor variations on “what matters”, and of course dealing with wall plug adapters.
No, Reboot is weird in a different way. In attempting to learn if it was more traditional conference, or unconference, the answer was never clear and often just “yes” to the multiple choice question. Now I know why they said that, it actually makes sense. But let me hopefully be slightly more lucid.
Reboot asks for anyone to submit topics ahead of time, and these are then chosen both by a committee as well as public voting – so it’s a very open system, BarCamp-like, but these talks are then chosen with a speaker and assigned times. So then Reboot becomes more traditional conference with many “stage talks” in a face-forward audience setting. There are some side rooms that will have sessions scheduled that are discussions, but that definitely isn’t something to plan on. So the presentations are more traditional.
But then where Reboot was really surprising is the amount of the conference that happens outside of the sessions. This isn’t just a “hallway track” discussions – they are full-fledged, conference long sessions working on projects. People are dedicated to building things, gathering together information, creating, ideating, collaborating, advising – all during the conference. I’m quite sure a sizable number of Reboot attendees never go to a ’session’ but merely use the venue as a mechanism to gather together many like-minded people who are driven to do something, and leverage the brain-power and thoughts that are coming out of the sessions to act on something bigger.
I love BarCamps – they’re discussion-centric, synergistic, and connect people in networks to carry forward and achieve great things in the future. What Reboot does, by comparison, is not wait. Have an idea? Get started on it now. Or at least be very good in capturing the idea, disseminating it widely and getting it moving as quickly as possible.
Now perhaps with a little better, or at least verbose, explanation of what Reboot was like from my perspective – it also makes the name itself more meaningful. The conference is Reboot, not “Reinstall”, or “Start-over”, or “Redo”, just “Reboot”. When you Reboot something you retain some measure of the longer-term state it was in; applications are installed, configurations are set, and so forth. But what Rebooting does is to go back to a fresh state, with the long-term memory and skills and infrastructure, and get up and running and back into business.
So the conference is about considering what’s around you, what you’ve built and have, and through the sessions, collaborations, projects, whatever, to take a fresh perspective and jumpstart on moving forward.
The theme, or topic, of Reboot 11 was “Action”. Simple, single word: Action. Take action, make something happen. There is a parellel in Tim O’Reilly’s “Work on things that matter”.
The proposed reasoning behind having Reboot focus on “Action” was that we are in a global economic crisis, there are short-term issues such as disasters, corrupt governments, and long-term problems of environmental quality, health, and education. It was a push for us to work on these issues and figure out how we can help enact change.
However I found through talking with many people that had attended several Reboots that there was “nothing new”, or “revolutionary” in many of the topics and that the individual felt they already had a good grasp of what was going on in the space. It was this malais of “amazing things” that made me realize why it’s really time to take action – and Bruce Sterling to cast just enough “Gothic Hi-Tech” to make it solidify”"
The tools we’re all using and building with have been in active use for several years now. We have our wikis, blogs, social networks, mobile devices, media devices, connectivity, realtime communications, hardware interfaces, API’s, and more. We have all created an amazing toolset that has been used to create many varied, and some quite crazy, applications, worlds, communities, or systems.
And if we have these mature tools, with many choices and the ability to quickly pull them together to accomplish nearly everything – we have to grow up and realize that these are not just toys or hacks nymore. These are the very tools that can, and are already, making the world of the future.
And we, the technologists, designers, thinkers, citizens of the next generation that are now in control. We have grown up with these tools, and in many ways we’re already using them to change governments, raise communities, run businesses, and live in our world.
For me, what I took away is to take responsibility and consideration for what I choose to do. Hacks and toys are fun – but as Bruce said, “if it’s not beautiful enough to show your friends, and doesn’t have a narrative attached to it, throw it away”.
Work on things that matter, and make them work by focusing on them like they matter. Your actions will make a difference, and if they don’t – you’re doing it wrong. Put it down, and move onto something else. Collaborate and work together to achieve great, actionable outcomes. You’re an amazing person with many talents, and we can all use amazing people like you. What action are you going to evoke?

My friend Jo asked on GEOS mailing list for approachable explanation of spatial relations and Dale Lutz from Safe Software suggested something I’ve not came across myself before and what (in generalised form) I’d consider as a great idea for…a book really :-)
The American Clean Energy and Security (Waxman-Markey) bill was passed by the US House of Representatives. The bill aims to reduce greenhouse-gas emissions 17% by 2020 and over 80% by 2050 compared to 2005 levels. A limited number of pollution permits would be issued. Most of the permits would initially be given away free to utilities, manufacturers, state governments and others. The permits could then be traded or sold.
The major features of the bill are
The Congressional Budget Office has estimated that if passed by the Senate the bill would cost an average of $175 a year per household. As I blogged about recently, according to a recent survey of 2,164 Americans conducted by researchers at George Mason and Yale Universities, a large majorities of Americans support policies for addressing climate change and renewable energy. And they are willing to put their money where their mouth is. Most of the respondents said that they were prepared to pay more to support renewable energy policies. For example, 72 percent supported a renewable portfolio standard that would require electric utilities to produce at least 20 percent of their electricity from wind, solar, or other renewable energy sources, even if it cost the average household an extra $100 a year.
The Scottish Parliament has passed a bill with very aggressive goals for green house gas emission reduction. The long term objective is to reduce emissions by 82% by 2050. The bill includes a shorter term objective of 42% emissions reduction by 2020. The government has released a delivery plan that oulines how these reductions will be achieved.
barcamp es algo así como una red internacional de conferencias (o desconferencias como se autodenominan) de ámbito técnico, orientadas a la interacción siendo más bien una reunión donde todo el mundo está invitado a participar, es decir uno asiste sabiendo que ha de contar algo a los demás.
Con estos tintes un grupo de gente capitaneado por Juanjo Martínez, de Open Sistemas, ha conseguido (les ha costado lo suyo) un sitio en el que celebrar una reunión, con un lema muy concreto: “Web 2.0, Open Source y Social Media“. La conferencia tendrá lugar el 25 de julio en Alfara del Patriarca (un pueblo muy cercano a Valencia) en las instalaciones de la Universidad Cardenal Herrera. Tienes toda la información en http://www.barcampvalencia.com.
En este contexto, y si no pasa nada, dos miembros de geomaticblog participarán presentando dos proyectos que casan a la perfección con el lema, Pedro-Juan presentará la fundación OSGeo y yo (con la ayuda seguramente de Iván García del ITI) el proyecto OpenStreetMap.
Los organizadores están buscando a gente que se anime presentar proyectos, porque ya que han conseguido dos salas, ¡¡hay que llenarlas!! Así que si te apetece contar algo en lo que andes metido (no hace falta ser un gran ponente ni nada parecido) no lo dudes y ponte en contacto con la organización. Si no te apetece contar nada pero te interesan los contenidos, puedes apuntare enviando un correo a inscripciones@barcampvalencia.com.
La conferencia se hace en una zona vecina a Moncada, donde Vicente que es del terreno ha hecho un gran trabajo, pero Alfara no estaba terminada así que le he pegado un repaso para que tengamos un bonito mapa que enseñar allí.
Actualización:
Han pasado unas horas ya tenemos renderizado la ubicación de la conferencia. Como wordpress.com todavía no deja insertar mapas dinámicos, podéis pinchar en la imagen para ir al mapa de la zona. Por cierto que tenemos una piscina cerquita para ir a darse un chapuzón o tomar una cervecita fresquita.
