45. Technology
Web services we are providing:
 GeoServer - provides WMS, WFS (generates the map tiles: PNG images from the map layers at different
resolutions)
 WebGeoCache - a spatial storage of already generated tiles
 PostgreSQL - relational database
 PostGIS - SQL based geographic operations
 Memcache-d - keeps generated webpages in the machines memory
Databases in use:
 Administrative boundary shapefiles
 MRLC NLCD rasters
 US Census
 i-Tree: Locations, Species, benefits, etc.
Software/Libraries (our application is primarily written in Python and JavaScript.)
 Python 3
• Django - running on Apache httpd through mod_wsgi
• - also provides CSS and JS compression
 JavaScript
• jQuery
• OpenLayers - map display
• C3 and/or ChartNew.js
• Twitter Bootstrap (JavaScript and CSS)
• Modernizer
 There are also many dependencies & configurations
maintained on the machine to support GeoServer and
PostGIS.
