Interactive Maps/GIS

GIS and mapping is increasingly moving to the web/cloud and many services are being developed to let you make your own maps and perform basic GIS operations. Web Maps/GIS range from simple online maps to complex interactive systems allowing users to layer, track, analyze, visualize, and export spatial data. The sites listed in this guide are a small sampling of what's available. Some sites are worldwide general systems, some cover specific geographic areas, while others are thematic.

  "Google Earth Engine is a cloud computing platform for processing satellite imagery and other geospatial and observation data. It provides access to a large database of satellite imagery and the computational power needed to analyze those images. Google Earth Engine allows observation of dynamic changes in agriculture, natural resources, and climate using geospatial data from the Landsat satellite program, which passes over the same places on the Earth every sixteen days. Google Earth Engine has become a platform that makes Landsat and Sentinel-2 data easily accessible to researchers in collaboration with the Google Cloud Storage. Google Earth Engine provides a data catalog along with computers for analysis; this allows scientists to collaborate using data, algorithms, and visualizations. The platform provides Python and JavaScript application programming interfaces for making requests to the servers, and includes a graphical user interface for developing applications." -- Wikipedia
