Fires

This is the repository for TileMill project of maps for intense and recent fires at infoamazonia.org.

Loading maps locally

  1. Clone this repository at your machine;

  2. Symlink TileMill projects:

     ln -s /path/to/repository/tilemill/fires-intense ~/Documents/Mapbox/project 
 ln -s /path/to/repository/tilemill/fires-recent ~/Documents/Mapbox/project

Updating data

  1. Download new data setting extents (West South East North) = (-85 -59 -29 16):

    http://firms.modaps.eosdis.nasa.gov/download/

  2. Unzip the downloaded file at data folder;

  3. Import downloaded files, replacing {new_data_file} with downloaded filename without extension:

     cd data
 spatialite_tool -i -shp {new_data_file} -d fires.sqlite -t fires -c UTF-8 -s 4326
 spatialite fires.sqlite < ../sql/update.sql

  4. Regenerate maps and upload to Mapbox:

  5. Commit changes to GitHub.

Regenarating data from scratch

If you need to regenate from scratch, download source files spliting by 3-4 years periods, e.g. 2000 to 2003, 2004-2006, 2007-2009,2010-2012, and so forth.

Merge then:

	ogr2ogr -select "ACQ_DATE","BRIGHTNESS","FRP" fires.shp fires_2000-2003.shp
	ogr2ogr -append -select "ACQ_DATE","BRIGHTNESS","FRP" fires.shp fires_2004-2006.shp
	ogr2ogr -append -select "ACQ_DATE","BRIGHTNESS","FRP" fires.shp fires_2007-2009.shp
	ogr2ogr -append -select "ACQ_DATE","BRIGHTNESS","FRP" fires.shp fires_2010-2012.shp
	ogr2ogr -append -select "ACQ_DATE","BRIGHTNESS","FRP" fires.shp fires_2013.shp

Init a Spatialite database with this data:

	spatialite_tool -i -shp data/fires -d data/fires.sqlite -t fires -c UTF-8 -s 4326

Create recent and intense tables:

	spatialite data/fires.sqlite < sql/create.sql
