Enhancements to this SPA include:
The Level 2 MODIS Active Fire Product (MOD14) Science Processing Algorithm SPA (MOD14_SPA) primarily uses brightness temperatures derived from MODIS 4 and 11 micrometer channels (bands 21, 22 and 31) to detect fires. MODIS bands 1, 2, 7 and 32 are used to reject false alarms and to mask clouds. The algorithm reads a MODIS 1-km Level 1B file along with the associated geolocation file and identifies active fires. The output is a two-dimensional fire mask in Hierarchical Data Format (HDF). Additionally the SPA creates a text file containing useful information (latitude, longitude, acquisition date, channel 21/22 brightness temperature, Fire Radiative Power [FRP], and detection confidence) for each fire pixel detected. The MOD14_SPA functions in two modes: Standalone, or as an IPOPP plug-in.
Follow the instructions below to install the SPA in a standalone configuration. SPAs may also be installed dynamically into an IPOPP framework; instructions for this type of installation are contained in the IPOPP User's Guide.
Download the MOD14_6.2.1_SPA_1.1.tar.gz and MOD14_6.2.1_SPA_1.1_testdata.tar.gz (optional) files into the same directory.
Decompress and un-archive the MOD14_6.2.1_SPA_1.1.tar.gz and MOD14_6.2.1_SPA_1.1_testdata.tar.gz (optional) files:
$ tar -xzf MOD14_6.2.1_SPA_1.1.tar.gz
$ tar -xzf MOD14_6.2.1_SPA_1.1_testdata.tar.gz
