esri2open - this repo is an ESRI toolbox and tool(s) that export ESRI Feature Classes to open data formats, CSV, JSON, and GeoJSON

•    Python

---

This repo is an ESRI toolbox and tool(s) that exports ESRI Feature Classes to open data formats, CSV, JSON, SQLite, and GeoJSON. Much of the data in government coffers is contained in spatial databases. A large percentage of government spatial data is created and managed using ESRI software. While the common interchange format, the ESRI Shapefile, is easily exported and imported by many other softwares, this data file format (the Shapefile) is not intrinsically part of the www ecology. Moreover, ESRI software does not provide an export of its generic 'feature class' (shapefile, file geodatabase, and personal geodatabase) to the most common open data file formats, CSV, JSON, and/or GeoJSON. Finally while open source tools easily transform ESRI shapefiles to open data, most government geospatial infrastructures only have ESRI tools. Lacking this basic export feature presented here, means the lion's share of government spatial data users cannot export their data to the most common open data formats.

ISO-3166-Countries-with-Regional-Codes - ISO 3166-1 country lists merged with their UN Geoscheme regional codes in ready-to-use JSON, XML, CSV data sets

•    Ruby

---

These lists are the result of merging data from two sources, the Wikipedia ISO 3166-1 article for alpha and numeric country codes, and the UN Statistics site for countries' regional, and sub-regional codes. In addition to countries, it includes dependent territories. The International Organization for Standardization (ISO) site provides partial data (capitalised and sometimes stripped of non-latin ornamentation), but sells the complete data set as a Microsoft Access 2003 database. Other sites give you the numeric and character codes, but there appeared to be no sites that included the associated UN-maintained regional codes in their data sets. I scraped data from the above two websites that is all publicly available already to produce some ready-to-use complete data sets that will hopefully save someone some time who had similar needs.
