modis

A library to work with MODIS HDF files.

System requirements

Modis delivers its products in hdf4 format and this library uses gdal to operate on those files. As such it requires gdal with dev headers and support for tiff and hdf4.

OSX

The standard homebrew port comes with hdf5, while hdf4 is generally not available in homebrew. This necessitates installing gdal from source. Besides, source installation allows to dramatically reduce the number of dependencies.

1. Install dependencies available in homebrew

   brew install pkg-config
   brew install libtiff
   brew install libgeotiff
   brew install proj
   brew install gfortran
   

2. Download and install hdf4

   Download from hdfgroup.org, e.g. hdf-4.2.15.tar.gz.

   Configure, make and install:

   CFLAGS=-Wno-implicit-function-declaration ./configure --prefix=/usr/local --enable-shared=yes --disable-static --disable-fortran --with-jpeg=/opt/homebrew/Cellar/jpeg/9e
   make && make install
   

3. Download and install gdal

   Download from gdal.org

   Configure, make and install:

   ./configure --prefix=/usr/local --enable-shared=yes --disable-static --with-hdf4=yes --with-proj=/opt/homebrew/Cellar/proj/9.0.0_1 --with-jpeg=/opt/homebrew/Cellar/jpeg/9e --with-libtiff=/opt/homebrew/Cellar/libtiff/4.3.0 --with-geotiff=/opt/homebrew/Cellar/libgeotiff/1.7.1_1
   make && make install
   

Now check supported gdal formats (gdal-config --formats) and build the library go build ..
