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

JavaScript code for generating Firebase Push IDs
/**
* Fancy ID generator that creates 20-character string identifiers with the following properties:
*
* 1. They're based on timestamp so that they sort *after* any existing ids.
* 2. They contain 72-bits of random data after the timestamp so that IDs won't collide with other clients' IDs.
* 3. They sort *lexicographically* (so the timestamp is converted to characters that will sort properly).
* 4. They're monotonically increasing. Even if you generate more than one in the same timestamp, the
* latter ones will sort after the former ones. We do this by using the previous random bits
* but "incrementing" them by 1 (only in the case of a timestamp collision).

GitHub Wiki How-To

How do I clone a GitHub wiki?

Any GitHub wiki can be cloned by appending wiki.git to the repo url, so the clone url for the repo https://myorg/myrepo/ is: git@github.com:myorg/myrepo.wiki.git (for ssh) or https://github.com/my/myrepo.wiki.git (for https).

You make edits, and commit and push your changes, like any normal repo. This wiki repo is distinct from any clone of the project repo (the repo without wiki.get appended).

How do I add images to a wiki page?

PowerShell, Cmder / ConEmu, Posh-Git, Oh-My-Posh, Powerline Customization

Pimping Up Your PowerShell & Cmder with Posh-Git, Oh-My-Posh, & Powerline Fonts

Backstory (TLDR)

I work as a full-stack developer at work. We are a Windows & Azure shop, so we are using Windows as our development platform, hence this customization.

For my console needs, I am using Cmder which is based on ConEmu with PowerShell as my shell of choice.

Yes, yes, I know nowadays you can use the Linux subsystem on Windows 10 which allow you to run Ubuntu on Windows. If you are looking for customization of the Ubuntu bash shell, check out this article by Scott Hanselman.

Pyspark script for downloading a single parquet file from Amazon S3 via the s3a protocol. It also reads the credentials from the "~/.aws/credentials", so we don't need to hardcode them. See also https://hadoop.apache.org/docs/stable/hadoop-aws/tools/hadoop-aws/index.html .

Enable High Quality mode on your headphones (Updated for macOS Catalina)

If you're using a high-end bluetooth headset on your Macbook Pro it's likely your mac is using an audio codec which favors battery efficiency over high quality. This results in a drastic degradation of sound, the SBC codec is the likely culprit, read more about it here.

Find out what codec you're using

  1. Play a song on your headphones
  2. Option (⌥) click the Bluetooth button at the top of your screen Inspect the Bluetooth Coded
  3. If you're using AAC or aptX, you can stop here—those are the highest quality codecs.

Change your codec to AAC or aptX
