## Deploying

Suggestion is to use cartocc for managing the local config (like db credentials, path to shp...). Have a look at the cartocc.json.sample file to quick start

1. Clone this dir

2. Symlink it in your MapBox/project directory with the name hdm

3. Rename cartocc.json.sample to cartocc.json and adapt it

4. run cartocc hdm: this will create a project.mml file with correct local config in the project dir

5. Run tilemill

We are using PostGIS, with the default osm2pgsql import style, AND with the hstore column. Ex.:

osm2pgsql -G -U ybon -d hdm data/haiti-and-domrep-latest.osm.pbf --hstore --create

1. get the file from CGIAR

2. Reproject it: gdalwarp -s_srs EPSG:4269 -t_srs EPSG:3785 -r bilinear srtm_22_09.tif haiti-3785.tif

3. Create hillshade: gdaldem hillshade -co compress=lzw haiti-3785.tif haiti-hillshade-80-3785.tif -alt 80

4. If you have more than one tiff for you covered area, merge them in a vrt file (remember to use absolute path): gdalbuildvrt haiti-hillshade.vrt ~/OSM/SRTM/srtm_22_09-hillshade-80-3785.tif ~/OSM/SRTM/srtm_23_09-hillshade-80-3785.tif

5. Create contour line: gdal_contour -a height haiti-3785.tif haiti_contour_25m.shp -i 25.0

6. Index shape file: shapeindex haiti_contour_25m.shp
