DESCRIPTION

We'll talk about how to take open data and visualize it on a map using open source technology at Transparency Camp 2011.

TRANSCRIPT

Design interactive maps using a CSS-like styling language.

Host maps exported from TileMill on a fast and light map server.

Take interactive TileMIll maps offline for mashing up with KML and GeoRSS.

Open Source: beautiful, fast, and easy

Telling Complex Stories with Maps

Targeted Users:- GIS experts - Data analysts - Program managers - Communication teams - Developers

Project BrowserTileMill’s main start page shows all the projects you are developing and helps you manage your data sets and quickly start a new project.

Editing InterfaceUsing a CSS-like language, the editor on the right controls the map style and updates it in real time.

Color PaletteTileMill keeps track of all the colors you use in a project, and makes it easy to edit them and add new ones.

Adding LayersLayers are how sets of data are added to a map in TileMill. Each layer references a single shapefile, geoJSON file, KML file, geoTIFF, or (soon) PostGIS database query.

Data ManagementAdding a layer opens a dialog you can browse to select shapefiles from your local machine.

Layer ManagementAll the data sets that you have brought into your map show up on the left hand side.

Layer Data InspectorYou can inspect any data layer

Exporting Maps Export your map to a PNG image or to an MBTiles file. You can also view past exports.

TileStream is a super fast map server for hosting maps (MBTiles) made with TileMill.
