Mapas Dinámicos Rápidos con OpenStreetMap, MapBox.js y Google Spreadsheets

En Tiempo para Desarrollando América Latina: Una Receta para Desarrollar Rápidamente Aplicaciones Geográficas

En los talleres de mapeo en preparación a Desarrollando América Latina de este fin de semana, pasamos una parte hablando de cómo utilizar Google Spreadsheets y MapBox.js. Es una arquitectura especialmente favorable en el contexto de una hackathon ya que permite rápidamente crear una aplicación para la colección y presentación de datos geográficos. Aquí les mostramos un ejemplo.

Registro de Incidentes Delictivos

Este sitio es un prototipo que desarrollamos con la Sub Gerencia de Seguridad Ciudadana de la Municipalidad Provincial de Huamanga. Permite registrar incidentes delictivos en la ciudad de Ayacucho y mostrar automáticamente los datos de manera dinámica y en tiempo real.

Dear RECIPIENT NAME,

In recent weeks we have made good progress in adding missing parts of CITY to OpenStreetMap [2]. If you haven't heard of OpenStreetMap before, it is like a WikiPedia of maps, providing a comprehensive, open map of the world [3] for anyone to use.

From your website I have seen that you manage street name information [4]. We would love to contribute it to OpenStreetMap to further complete the data of CITY, but we have questions around the licensing of this data.

What are the conditions under which you make street name data and other geo data available?

If you have any specific questions, I'd be happy to get on the phone with you and explain more.

About this map

School Performance in America

This map contains the latest available data on graduation rates, math and reading performance for the time between 2007 and 2010. This is data that has been published by the Department of Education continuously since [YEAR], for the first time it is made available through an easy to explore interface and as download in an open format.

Sharing the map

At any time, you can grab a snippet of the map and embed it in another web site - just like a YouTube video. The embed will maintain the exact location you have navigated to.
