Joining Tables with SQL using pyQGIS
One of the features that makes MapInfo’s MapBasic very useful is the ability to join a normal tabular data with a spatial data using plain SQL statements within an application. This is useful because it makes it possible to link numerous attribute tables (census, crime, marketing, etc.
Geoserver Security using the Seasar Web Framework
Although Geoserver has its own valid Security system, exposing it directly to the internet still raises concerns, especially if Geoserver is being used to host corporate data. One source of these concerns is that Geoserver offers numerous Services that have to be closed properly, and a single unintended mistake in closing these Services might lead to an unauthorised access to the Services or sensitive data.
pgRouting 2.0 is coming soon
With the (inofficial) alpha, beta and rc1 release of the new pgRouting 2.0.0 lots of smaller and bigger issues have been fixed: for example TSP now accepts a start and also an end point, the “develop” branch is checked on Travis CI with every commit and tested with different versions of PostgreSQL/PostGIS, the documentation can be translated with Transifex , etc.
Georepublic at FOSS4G in Notthingham
In September the annual FOSS4G will take place in Nottingham, and beside being a sponsor Georepublic will attend the event with three of us travelling from Tokyo and Osaka. We are also planning to attend State of the Map in Birmingham, UK and the Quantum GIS Developer Meeting in Brighton before heading to FOSS4G.
The Cuisines of the world
Tags or tagging are quite underrated in mapping where colourful lines/dots make up for most of the look and feel. OpenStreetMap as the name says is an open map but also is a open geographic database licensed under ODBL .
Leaflet example with WFS-T
This article is supposed to be No. 15 in the Japanese FOSS4G Advent Calendar 2012 and it’s probably the first and last one in English for this year. First I wanted to build pgRouting Ubuntu packages and write about it, but then I saw the other great blog posts and decided to change the topic.
How to contribute to an existing Octopress blog
You managed to setup your own Octopress blog? Great! After a while you switch to another PC or your colleague wants to contribute an article and nothing worked as easy
The Georepublic Times is using Octopress
Let’s start with a first post about how to publish articles on Georepublic’s brand-new blog. Since the writing of blog articles has almost stalled in this year, even if Georepublic’s population nearly doubled since 2011, there was probably something wrong the old blog system.
PostGIS and pgRouting template
When creating a new database in PostgreSQL using the standard template, PostGIS and pgRouting functions and tables are missing of course. You can add these functions and tables one by one, but doing this every time for every single database is annoying work.
pgRouting Project News
It has been a long way but finally we made it: I’m glad to be able to announce the new pgRouting website, that also comes with a lot of other changes and news!
