Download

Download this zipfile or clone the repository on your computer:

git clone https://github.com/oeco/infoamazonia-maps.git

Adding a map project to TileMill

The map projects are located in tilemill folder and you can copy them to the TileMill project directory, often located at ~/Documents/Mapbox/project. Alternatively, you can create a symlink to your local git repository. For example:

ln -s ~/path-to/oeco-amazonia/maps-src/tilemill/deforestation ~/Documents/Mapbox/project/deforestation

This will let you use git to track changes made in TileMill.

An effort has been made to point all non-postgres layers at directories in the dropbox, minimizing set up time. You can move data layers into git-tracked directories but be sure to use 'git checkout' to make sure they're not pushed to the GitHub repo - this will needlessly slow down everyone's pulls, especially as this data already exists in the dropbox.

Many layers are powered by a postgis database that allows reformatting of dates, area numbers, etc. To set up this data base run from your command (bash) shell:

createdb amazonia
psql -d amazonia -c "CREATE EXTENSION postgis"

All of this data I've included in a database dump calle 'desmata.sql'. A zipped version can be found in the dropbox here:

~Dropbox/InfoAmazonia_data/1_environmentalLayers/deforestation/amazonia.dump.zip

Run this command to populate the database

psql -d amazonia -f amazonia.dump

NOTE: this assumes you are running postgis2.0

Deforestation

Historical deforestation is powered by the 'desm91' shapefile that lives here:

~/Dropbox/InfoAmazonia_data/1_environmentalLayers/deforestation/IBGE/deforestation_1991_shp/desm91.shp

More recent deforestation is powered by the postgis database, for the above reasons but also so that 'last3months' table retrieves the last 3 months of deforestation data, regardless of when the last import of data was. The desmata.sql database dump includes data from jan 2005 to mar 2012.

You should now be able to open the project in TileMill.

Updating deforestation

To update the table, download the latest DETER update (the link is on InfoAmazonia ). Then reproject :

ogr2ogr -s_srs EPSG:4291 -t_srs EPSG:900913 deter_june2012.shp deter_201206.shp

Now you can run the following command from you bash shell (this example will import the DETER data from june 2012):

shp2pgsql -D -a deter_june2012.shp desmata | psql -d amazonia

NOTE: Be sure to include the -a option, as this will append the monthly data rather than overwrite the existing table with the update!

Once the import is complete you will need to update and optimize the tables in your database. Run the following command included in maps-src.

psql -d amazonia -f desmata-update.sql 

Deforestation data from Imazon SAD

Fires

Mining (and protected areas)

• After installing you will need to move the mining.zip file that exists at ~/Dropbox/InfoAmazonia_data/1_environmentalLayers/ to oeco-amazonia/maps-src/tilemill/mining/layers/ and then unzip it.
• to regenerate the map, you will need an older developer build (some of the features this map uses have been in rapid development). specifically you'll need Tilemill v0.9.1.6x version.
• the project should now work. be careful not to commit the data layers, as they will weight down the repo.

Other info

Legends should already be saved in TileMill projects, but have also been saved as an html file at oeco-amazonia/maps-src/legends-src.html. The same is true of tooltips, which live at oeco-amazonia/maps-src/tooltip-src.html
