Yet another mapping API

CloudMade, the professional service around OpenStreetMap, is offering a pre-alpha web and mobile maps API to developers.

The interesting thing about the CloudMade API is easy access to OpenStreetMap data. Compared to commercial map data used in other APIs, like TeleAtlas or NAVTEQ maps, OpenStreetMap shows addtional features like footpaths, bike lanes or tramway tracks in urban areas. Not a crucial feature, right, but here OpenStreetMap is closer to traditional city maps, maps made for pedestrians, than others are. it’s surely an interesting aspect for providing tourism or travel mapping services. Nokia maps go into that direction too and provide special features like pedestrians navigation for instance.

Another point for OpenStreetMap is its appealing cartography. Since it’s possible to export and download OpenStreetMap as vector data, I wonder if the CloudMade API provides methods for manipulating and customizing visual attributes of the map, like colors or stroke widths. That would really make a difference compared to other mapping APIs. Service providers or developers could almost draw their own maps, make their mapping service visually different from others or just highlight map elements they want to emphasize.

Thanks to the export feature of OpenStreetMap’s web interface, I started using it as background map on my GPS device. A lot of places are still missing, some places aren’t as accurate as in other maps, but it’s pretty easy to cut a map slice out of OpenStreetMap’s web interface and load it onto a GPS device (instructions).

More imagery and higher resolution for Austria

As result of a cooperation between Google and Geoimage-Austria, more parts of Austria (even rural areas!) are now as amazing 25cm high resultion imagery available in Google Maps (in Google Earth soon):

In Geoimage-Austria work five (out of nine) Austrian federal states together with LFRZ on creating imagery for this country. LFRZ is a former public agency, since 10 years an outsourced private company and providing the public sector with geo-technology. Their schedule is to cover the entire country with such high resolution imagery until 2009. [via GEObranchen]

In search of the point

What’s the point of having a national mapping agency when even semi-public agencies like our Umweltbundesamt (environmental agency) are doing data dissemination based on Google Maps and Geonames? [via joesonic]

Speaking of paleogeography is in that case certainly appropriate: neogeography makes the national mapping agency look like an endangered species. Even though I never really liked the terms and heated discussions about paleo- vs. neogeography. To me, paleogeography sounds way too negative for what it actually does. Paleogeography still provides a major part of the backend and a lot of necessary knowledge for the so called Geoweb. Period.

While neogeography is the cool thing. It’s fresh, slick, easy to use and attracts a lot of bright people outside the geography area who are doing amazing things with geographic information. Personally I see myself somewhere in between and try to get the best out of both.

Obviously some paleo organizations, like our national mapping agency is for instance, should look slightly to the left and to the right of their very straight path. It seems they are still serving the geo market of the last century. Their traditional products, like the topographic and cadastral maps, are certainly great and important works, but in the meantime they have to face the fact that the geo market has a little changed in the last couple of years.

Believe it or not, even in Austria there are map based businesses growing. Companies or start-ups who arrange their business models around easy and affordable access to local geographic information. Most of them depend on the goodwill of global players like Google or Microsoft. The EC usually is very quick when it comes to express concerns about monopolies of those companies and threaten them with law suits. I think, as for the geo market, the European mapping agencies have enough resources – in terms of geo data, infrastructure and knowledge – to throw into the game. They are powerful enough to compete with the big players, provide alternative map services and eventually support local economies. If they only wanted to.

Besides, the above mentioned example shows very well the benefits of neogeography for the public sector and that there is growing demand for such technologies.

So, again, where is the point of keeping a huge tax funded public body when it rejects to move on, serve current public needs, support local economies and public wealth?

The Server-side

More than any marketing leaflet, the Google/ESRI Where 2008 presentation made me curious about the potential of the upcoming ArcGIS Server release.

I find the example shown of the fires in California, where students started locating and pinpointing new fire outbreaks in Google My Maps, very interesting. In the field of spatial planning, stakeholder participation is often a crucial part. Since most projects deal with spatial impacts, using maps and plans is just natural to transport information. Enabling feedback processes directly via easy-to-use map interfaces like Google Maps or Microsoft Virtual Earth could support communication strategies very well I think.

The thing is, our clients, partners and most stakeholders aren’t GIS power users. They are not very familiar with desktop GIS and, for obvious reasons, use map server interfaces only when they are forced to (the “Captive” user base). Anything what helps increasing user experience on interactive maps is just a huge step forward.

Arc2Earth is handy for quick & easy interactive map publishing via Google Maps/Virtual Earth or KML, but the potential of having feedback collected, (geo)processed and instantly returned by a server leaves room for some really great project ideas and use cases.

I guess first I’ll have a look at the GeoServer project and see what I can accomplish with the Open Geo-Stack, before bothering our local ESRI sales people.

To be sweded

I would be up for sweding

Unfortunately I don’t call a VHS-camera my own, but that should be easy to overcome…
