This is a Ergo Training Manual for the visiting students (Eujeong Choi and Jaebeom Lee) from S. Korea. This document can be a good starting base for the official manual.
Hazard
Background
- See Hazard Introduction for links to hazard attenuation information
Hands on with Ergo
Built-in Attenuation functions on Ergo
How to create a scenario earthquake UI
Create Ergo Input Dataset (ESRI Arc/Info Grid ASC format) from USGS shakemap data (by using QGIS)
Download
- Download the data from USGS shakemap (http://earthquake.usgs.gov/earthquakes/shakemap/)
- Select a region (or network)
- Select download link
- Download GIS Files - Shape Files (ESRI shapefile format)
- Unzip the downloaded file
Rasterize (vector to raster)
- Since the data from USGS site is in vector format (polygons), it needs to be converted to ASC format for Ergo Input
- Open the shapefile (pga.shp) in QGIS (we will create PGA raster data)
- Rasterize the vector data by the menu: Raster - Conversion - Rasterize
- Input file: the shapefile for conversion
- Attribute field: Value
- Output file: select Geotiff and give a name (extension: tif)
- Note: current version of QGIS rasterizer can't support ASC format directly
- Raster size
- default: 3000, 3000
- You can increase the size to decrease the file size (but sacrifice the accuracy)
Geotiff to ASC
- Convert the format from Geotiff to ASC by the menu: Raster - Conversion - Translate
- Input layer: the geotiff layer you created from previous step
- Output file: select Arc/Info Grid Ascii (ASC) and give a name
Importing Raster data as a hazard
- Convert USGS vector to raster and import into Ergo, see Importing ASCII Raster guide
- Use the imported hazard in an Ergo damage analysis (e.g. building damage analysis).
Adding Attenuation Model
- Create a new plugin for the attenuation model, add dependencies
- Create a new extension and generate the class for the new model
- Add plug-in to Ergo launcher to make new model available
