You will get PostGIS codes for conducting spatial queries/analysis and data engineering.

Project details
Did you know that databases can store geographical data? With the help of spatial extensions, a database can store the locations of stores, ATMs, hotels, streets, districts, and other points of interest. Moreover, you can use SQL queries to process this information.
In this course, you'll learn about PostGIS, a spatial extension of the PostgreSQL database. You will learn how PostGIS stores geographical data and how its basic geographical functions can be used in simple and complex SQL queries.
To make your learning process more interesting, we'll be working with both real and not-so-real places in San Francisco and the United States. Additionally, we've prepared a special surprise—some exercises will even let you see the results of your queries drawn on a real-world map!

Steps for completing your project
After purchasing the project, send requirements so Sayyed can start the project.
Delivery time starts when Sayyed receives requirements from you.
Sayyed works on your project following the steps below.
Revisions may occur after the delivery date.
Checking data.
Checking the data as per data types, column names, and defining the columns that we need to focus on.
Data cleaning
If there are miss-lead data, we need to run some cleaning processes like dropping the empty cells, and the not important columns.
