TestMain() Pattern
// Because TestMain() is an init method and should (in most cases) only be called once, one must wrap it to extend the functionality
//
// 1. This code should exist in a setup_test.go (descriptive name) file
// 2. Setup/Teardown methods along with variables/connections/assets for specific tests should be written inside of the specific test file
// Example Filename: some_random_test.go
// Setup Method: someRandomTestSetup()
// Teardown Method: someRandomTestTeardown()
// 3. The Setup/Teardown methods are added to the global testMainSetup()/testMainTeardown() to centralize and organize your test suite

Processing LiDAR to extract building heights

Walk through

Detailed walk through of building extraction using postgis

First lets pull a data layer from of openstreetmap. You can do this any which way you’d like, as there are a variety of methods for pulling openstreetmap data from their database. Check the [wiki] (http://wiki.openstreetmap.org/wiki/Downloading_data) for a comprehensive list. My favourite method thus far is pulling the data straight into QGIS using the open layers plugin. For those who may want to explore this method, check [this tutorial] (http://www.qgistutorials.com/en/docs/downloading_osm_data.html). For building extraction you only need building footprints, and include the building tags. Not all polygons are of type building in OSM, so we can download all the polygons, and then filter the layer for only polygons tagged as buildings.

LiDAR data was pulled from USGS via the Earth Explorer site. [Here] (http://earthobservatory.nasa.gov/blogs/ele

A few examples will help to clarify these operations. Let's begin by creating two arrays:
operating_systems = ["Fedora", "SuSE", "RHEL", "Windows", "MacOS"]
linux_systems = ["RHEL", "SuSE", "PCLinuxOS", "Ubuntu", "Fedora"]
Now, we can create a union of the two arrays:
operating_systems | linux_systems
=> ["Fedora", "SuSE", "RHEL", "Windows", "MacOS", "PCLinuxOS", "Ubuntu"]
