Geographic Information Systems (GIS): About

Introduction

Geospatial datasets are scattered throughout the internet. In this guide, we compile online sources into an index with an interactive interface. The objective is to make it easier for researchers to know what data is available for a given theme.

All sources in this guide contain location-based data. Many of them are in ready-to-use GIS formats such as shapefiles. Other formats include tables or graphics of maps; you may convert them into GIS formats either by joining with existing GIS data, or by georeferencing. If you need help in data conversion, please .

This guide is a first release, and we welcome your . The interface is a modified version of DynaTable and we will share the code when the documentation is ready.

Using the data guide

1. Click on each checkbox with your thematic keywords of interest. The list may take 1-2 seconds to load.

2. To filter the list by keywords found in description (eg. country etc.), type into the text box and press <enter>.

If necessary, click on column name to toggle sorting.

Before using, always assess if the data quality fits your purposeTo use the data, you may need GIS software; the leading commercial software is ArcGIS, and QGIS is a great open source alternative.
