近年QGISの利用者,開発者が増加するにつれ多くの機能やアイデアがQGISに集積してきています.Wired誌の昨年のOpen Source Rookie Of the Year awardにはQGISの災害対策用プラグインInaSAFEが選出されました.10月21日には無料版のGoogle Maps Engineの発表とともにQGISとの(ESRIもですが)統合がGoogleからアナウンスされGoogle Maps Engine Connector for QGIS Version 1.0がリリースされました.Webやクラウドでは処理できない多種多様な空間データ操作はQGISにまかせてクラウドと統合していこういう動きです.レガシーテクノロジーであるデスクトップGISがなぜかここにきて脚光をあびています.オープンデータの動きが加速化する中で空間データを扱うための高機能プラットフォームとしてQGISが注目を集めているのでしょう.FOSS4G2013開催中の9月20日にリリースされたQGIS2.0は高い性能と豊富な機能、拡張性をそなえFOSS4Gの新たな利用シーンを牽引していくソフトウェアとなっています.本発表ではQGIS2.0のリリースまでの過程とそれを取り巻く新たな利用環境について述べたいです.
This document summarizes the development of a public toilet search system using open data and chatbots in Tokyo, Japan. The system allows users to search for the nearest public toilet by sending their location or address to a chatbot on the LINE messaging app. The chatbot searches a Voronoi diagram built using open data on public toilet locations from Tokyo and two cities. Search results include the toilet name and a photo link. While evaluated positively, challenges remain in adding search filters, transportation directions, and internationalizing the system and data.
- The document describes Yoichi Kayama's work extending spatial data functionality to the CKAN open data platform to support the Japanese government's open data and spatial information initiatives.
- Key extensions to CKAN implemented include improving the spatial resource preview function, adding spatial data processing tools using GDAL/OGR, overlay mapping of multiple spatial resources, and enabling purchase of spatial data products from private companies through the system.
- Future plans include public launch of the system in November along with incorporating paid data from private sector vendors.
1) The document introduces a web site created by Yoichi Kayama to provide public information about a disaster using open source tools and open data.
2) The site included satellite images, oblique photos of damage areas, and results from image analysis displayed on an OSM map. It also included a search function to find related disaster information by address.
3) Using open data, open source software, and cloud computing allowed the site to be created quickly to benefit the public in the aftermath of a major earthquake in Japan.
Introduction of flood evacuation route search system using QGIS,PostGIS,GRASS...Yoichi Kayama
?
The document describes a flood evacuation route search system that uses QGIS, PostGIS, GRASS and pgRouting. Raster flood area data from LIDAR is converted to vector polygons in GRASS and loaded into PostGIS. PgRouting is then used to search for evacuation routes while avoiding flooded roads using the spatial queries in PostGIS. The results are displayed on maps in QGIS to help identify safe evacuation routes over time as flooding progresses. Open source GIS tools were crucial for building this system to analyze spatial data and flooding scenarios.
