This page lists sources for data, including some which has been pre-formatted for easy import into Sahana Eden.
== Asia ==

=== India ===
Admin Boundaries:
* [http://eden.sahanafoundation.org/downloads/IN_Lx.7z IN_Lx.7z]

These have come from [http://gadm.org GADM]. The state name 'Orissa' has been updated to 'Odisha'.

Use [http://7zip.org 7-Zip] to extract to your web2py folder & then install like this:
{{{
cd /home/web2py
p7zip -d IN_Lx.7z
python web2py.py -S eden -M

auth.override = True
resource = s3db.resource("gis_location")
stylesheet = os.path.join(request.folder, "static", "formats", "s3csv", "gis", "location.xsl")
import_file = "IN_L0.csv"
File = open(import_file, "r")
resource.import_xml(File, format="csv", stylesheet=stylesheet)
db.commit()
import_file = "IN_L1.csv"
File = open(import_file, "r")
resource.import_xml(File, format="csv", stylesheet=stylesheet)
db.commit()
import_file = "IN_L2.csv"
File = open(import_file, "r")
resource.import_xml(File, format="csv", stylesheet=stylesheet)
db.commit()
import_file = "IN_L3.csv"
File = open(import_file, "r")
resource.import_xml(File, format="csv", stylesheet=stylesheet)
db.commit()
gis.update_location_tree()
db.commit()
}}}

=== Philippines ===
Admin Boundaries:
* [http://eden.sahanafoundation.org/downloads/PH_Lx.7z PH_Lx.7z]

These have come originally from [http://gadm.org GADM] but have had L1s inserted by [http://www.philgis.org/freegisdata.htm PhilGIS] so their L1s become L2s, etc
* Region Names have been modified to the format used by DSWD (Department of Social Welfare & Development)
* A couple of other names have been corrected (e.g. Kalookan -> Caloocan)

Use [http://7zip.org 7-Zip] to extract to your web2py folder & then install like this:
{{{
cd /home/web2py
p7zip -d PH_Lx.7z
python web2py.py -S eden -M

auth.override = True
s3db.gis_location_name.language.requires = IS_IN_SET({"tl":"Tagalog"})
resource = s3db.resource("gis_location")
stylesheet = os.path.join(request.folder, "static", "formats", "s3csv", "gis", "location.xsl")
import_file = "PH_L0.csv"
File = open(import_file, "r")
resource.import_xml(File, format="csv", stylesheet=stylesheet)
db.commit()
import_file = "PH_L1.csv"

db.commit()
import_file = "PH_L3.csv"
File = open(import_file, "r")
resource.import_xml(File, format="csv", stylesheet=stylesheet)
db.commit()
import_file = "PH_L4.csv"
File = open(import_file, "r")
resource.import_xml(File, format="csv", stylesheet=stylesheet)
db.commit()
gis.update_location_tree()
db.commit()
}}}


=== Vietnam ===
Admin Boundaries:
* [http://eden.sahanafoundation.org/downloads/VN_Lx.7z VN_Lx.7z]

These have come originally from [http://gadm.org GADM] but with their L1 removed (so we use their L2 as our L1, etc)
* GADM file has terrible problems with place names: at least 3 different encodings!
* These have mostly been resolved & the file contains place names with no diacritics (to make it easier for non-Vietnamese to search for such places) as well as Vi name_l10n
* Many updated boundaries from http://gis.chinhphu.vn by selecting the place & then using this JS:
{{{
points = plHighlight[0].latlngs[0];
output = 'POLYGON ((';
for (var i=0; i < points.length; i++) {
    p = points[i];
    output += p.longitude;
    output += ' ';
    output += p.latitude;
    output += ',';
}
output = output.slice(0, -1);
output += '))';
}}}
or
{{{
output = 'MULTIPOLYGON (((';
points = plHighlight[0].latlngs[0];
for (var i=0; i < points.length; i++) {
    p = points[i];
    output += p.longitude;
    output += ' ';
    output += p.latitude;
    output += ',';
}
output = output.slice(0, -1); // Strip comma
output += ')),((';
points = plHighlight[1].latlngs[0];
for (var i=0; i < points.length; i++) {
    p = points[i];
    output += p.longitude;
    output += ' ';
    output += p.latitude;
    output += ',';
}
output = output.slice(0, -1); // Strip comma
output += ')))';
}}}
& then converted to WGS84 using:
{{{
ogr2ogr -f CSV CSV VN2000 Polygons.csv -s_srs EPSG:3405 -t_srs EPSG:4326 -lco GEOMETRY=AS_WKT
}}}
* Old boundaries have been left and start / end dates have been added from Wikipedia.
