Creating a WMS Time service with MapServer
In this recipe, you will implement a WMS Time with MapServer. For time-series data, and whenever you have geographic data that is updated continuously and you need to expose it as a WMS in a Web GIS, WMS Time is the way to go. This is possible by providing the TIME
parameter a time value in the WMS requests, typically in the GetMap
request.
Here, you will implement a WMS Time service for the hotspots, representing possible fire data acquired by NASA's Earth Observing System Data and Information System (EOSDIS). This excellent system provides data derived from MODIS images from the last 24 hours, 48 hours, and 7 days, which can be downloaded in shapefile, KML, WMS, or text file formats. You will load a bunch of this data to PostGIS, create a WMS Time service with MapServer, and test the WMS GetCapabilities
and GetMap
requests using a common browser.
