Alat ini akan memperoleh data (‘struktur’) bangunan dari projek OpenStreetMap untuk Anda.
InaSAFE supports the use of building data in various impact functions. In particular we support building footprints sourced from the OpenStreetMap project (OSM). The tool requires internet connection as it fetches the data via a web service running on Linfiniti’s OSM Reporter web site.
The data, once downloaded will be available to you as a shapefile. A style file is automatically created so that it symbolises nicely in QGIS. In addition, the correct keyword metadata is created for the downloaded dataset so that it can be used directly in InaSAFE impact scenario analyses.
Note: The building downloader service has limitations as to the size of datasets that can be retrieved. As such you may experience issues trying to fetch e.g. country wide building footprint data. Generally datasets at a city level and below should work well.
Untuk menggunakan alat ini secara efektif:
Warning
Jika dataset sudah ada di direktori output, dataset tersebut akan ditimpa. Alat ini memerlukan koneksi internet untuk bekerja dan mengambil bangunan akan menggunakan bandwidth Anda.
