Creating RasterFrames

Initialization

There are a couple of setup steps necessary anytime you want to work with RasterFrames. the first is to import the API symbols into scope:

metasim

    {
        "jmhVersion" : "1.20",
        "benchmark" : "org.locationtech.geomesa.spark.jts.WKBNumPointsBench.deserializeNumPoints",
        "mode" : "thrpt",
        "threads" : 1,
        "forks" : 1,
        "jvm" : "/Library/Java/JavaVirtualMachines/jdk1.8.0_161.jdk/Contents/Home/jre/bin/java",
        "jvmArgs" : [
