With the rise of geographic-interest via map mashups, mobile location, and geotags, there is now a slew of sites rising up to start aggregating and collecting all the of the localized information and news.
PlaceBlogger is apparently just about to start. It’s an aggregation of localized blogs. Blogs with posts about specific locations, like the neighborhood or suburb rather than just a larger metro area - dubbed hyperlocal. You can see a mockup here. It’s like a Yahoo frontpage, but centered around neighborhoods or areas of interest. (via Susan Mernit
Another site is outside.in (read the announcement and some thoughts here) which is already released and has data. At first it wasn’t quite apparent how to start contributing to the site or marking up locations. They refer to the GMAP format, but I’m not sure what that really means.
All of these sites and tools are really exciting. This is the purpose behind tools I’ve been working on like GeoPress and Mapufacture. I hope these other local-news aggregators also use and support broader, open formats that we can all share and play along together.
Also check out LocoBlog, which is a mobile-phone blogging application and site as well.

All the emerging standards for simple markup and syndication of location are Earth-centric (and sometimes just US/North American-centric). Granted, most people are probably only interested in locations that they can actually go to anytime soon.
However, with the increasing number of interplanetary rovers, observations of moons, and perhaps future excursions, it is still useful to define how to properly handle these other reference frames. Luna and Mars are two suggested Microformats that are starting the discussion on how one might mark locations on the two bodies. Additionally, the OGC is working now on determining standards for scientists and developers to publish and share data sources of planets, moons, asteroids, comets, ‘oh my’.
And why does the Earth have to be the only one with cool, “slippy maps”. I quickly put together a map of Mars. It uses the powerful OpenLayers Javascript mapping library to display the tiles from a NASA WMS server.

To produce the locations for the map, I put up a Space Blog, using WordPress and a slightly modified GeoPress to publish Mars lander locations and landing dates. I altered the published Microformats produced by GeoPress to make the class “geo mars” as a suggested way to markup Mars coordinates. The published GeoRSS feeds from the Space Blog then produce the locations and layers automatically on the OpenLayers Mars Map.
To Do: CRS and You
So this is all very neat, and in the end, really easy to setup. However, this is just a demonstration and in no way should be construed as “the way to do it”. Specifically, there are these questions left unanswered:
- How to define the Microformat and GeoRSS for non-Earth (and non-WGS84) reference frames
- How to define the Microformats and GeoRSS/Geonames location for non-Earth locations (like “Ares Vallis”)
- More sources for interplanetary map servers
- Ways to syndicate, and subscribe to, specific bodies
- Support for publishing, consuming, and drawing lines - in order to plot out mission profiles
- Support for publishing, consuming, and drawing areas - in order to plot out mission profiles, landing sites, and expected areas of “mission failures”
I’m sure there are more issues, so please speak up. You know who you space geeks are.

GeoRSS, Maps
Dan Karran has been working on making a Geospatial Content Management System (GeoCMS) using Drupal and using the existing location modules which adds location information to any node. Additionally, he’s written GeoRSS and KML modules, that allow for consuming and publishing these geospatial feeds. In Drupal, everything is a node. So when consuming feeds, new nodes can be created for locations that are consumed. Then information, links to other nodes, and various other metadata can be associated to this node, and it is then aggregated back out for other services to consume, display, and reaggregate.
This work is a perfect example of the point of my talk at FOSS4G, Enabling Users to Produce Personalized Geodata. It’s more important for developers to add geographic capabilities to existing, and widely used tools than to make geo-specific tools and expect users to come and use them. People are already using Drupal for their content, and now they can easily add location data and share it with their users and consume feeds.

GeoPress, GeoRSS, Maps, Project

O’Reilly Radar was the first to announce the release of GeoPress, a WordPress blog engine plugin that allows you to easily add location to blog posts, embed dynamic maps, and add GeoRSS encoding to your RSS output.
There have been other geo plugins before. However, they usually required you to make your own modifications to your template and provided a fairly arcane interface. The goal of GeoPress was to make adding location as simple as possible. Once you install GeoPress (copy and unzip to a wp-content/plugins/geopress directory on your WordPress site), and activate it (on the plugins panel), your configuration is done. Then go to write a blog post and you’ll see a new area with a map and boxes underneath the post.
You can enter an address, or a city, or just a country, or even click on the map to set the location. You can then add a name which will be saved and can later be used for quick reuse. If you want to insert a map into your post, just type INSERT_.MAP somewhere in your post. You can also use INSERT_.ADDRESS and INSERT_.COORDS, which will insert the address and coordinates, in appropriate adr and geo Microformats. Since GeoPress uses Mapstraction, you can switch between displaying Yahoo, Google, or Microsoft maps with just a quick select in your settings.
There are also some PHP functions for modifying your template to embed maps or post locations. Using geopress_map() you can embed a map of all your locations. the_address() can be used in your post metadata to always automatically output something like “this post was written by Bob from Waikiki, Hawaii”.
Lastly, the part that will be most useful in the future, is that the locations your write about will be embedded as GeoRSS in your RSS feeds. Aggregators like Mapufacture or FoFRedux will now be able to aggregate your geographic data and allow others to easily find interesting places, and build mashups.
