In this post, I will demonstrate loading my criminal activity data into ElasticSearch sot it can be explored, analyzed and visualized in Kibana. For instructions on installing and configuring the Elastic (formerly ELK) Stack, see my previous post. Although this post will specially reference the crime data from my PostgreSQL database, I will include additional…
Exploring Mapping Data In a continuation from part 2a, this post will explore the spatial points datasets from my database. I need to assess what each dataset contains. To aid in the exploration of spatial data, I will demonstrate plotting spatial points. This can be a lot easier to look at this particular structure in…
Exploring Mapping Data My next exploration task is the mapping/geospatial tables in my database. I need to assess the what each dataset contains. To aid in the exploration of spatial data, I will demonstrate plotting of spatial points and polygons. This can be a lot easier to looking at this particular structure in tabular or…
Exploring Criminal Activity Data My primary data set to explore is the crime table in my database. I need to assess the values and consistency across each of the fields available in what was provided by the source. It is possible for data to be a little inconsistent across each of the years over the…
Thus far I have gathered and stored my data for the vast majority of the project into my PostgreSQL database. Now its time to explore the data. Over the next series of posts for this project, I plan to share different methods of exploring the data. Initially I’ll demonstrate using R to tap into my…
This post will describe the implementation of the star schema using the “Crime” table from my Criminal Analysis project. The original table represents criminal incidents in Washington DC from 2009 through 2020 (October). The table also has 23 columns, 7 of which are spatial grouping categories. I’ll demonstrate how to decompose the table of data…
I have gathered three quarters of my branches on the “Other Data Sources” category. The next up is to get real estate data based on the project plan. Real Estate Data Finding good real estate data took a some work to explore and gather. I’m sure there is a lot of data available privately for…
In this post I will go over setting up a geospatial database using PostGIS, an extension to PostgreSQL. For information about setting up a PostgreSQL database please refer back to my previous Data Storage. Below is the project plan to ensure I load up all my downloaded map data. Installing and Setting up First you…
Now that we have collected our data, lets work on building a database to store our project data. For this project I have decided to use a PostgreSQL database. The image below provides some planning details to help us implement the database. Installing and Setting up On a Linux machine, getting PostgreSQL installed and running…
So far I have gathered half of my other data sources. The next up is to get employment and real estate data based on the project plan. Employment Data I generally searched for “Washington DC” and “employment data” but later modified it a little based on the results I got. https://duckduckgo.com/?t=lm&q=washington+dc+employment+data&ia=web https://duckduckgo.com/?t=lm&q=Washington+DC+unemployment+data+historical+data&ia=web DC Department of…
