TABLE OF CONTENTS

This course will teach you how to download, evaluate, and prepare GIS data from public online sources and set up a project in ArcGIS Pro.

...

There are three ways of obtaining the tutorial data. The best option for getting the full GIS project experience is to follow Option 1 and learn how to download data from online GIS data portals. You will also gain exposure to the best GIS data websites for the Houston region. If you have limited time or if any of the data provider websites are not functional, you may get a downloaded version from the computer  Before beginning the tutorial, you will copy all of the required tutorial data onto your Desktopdownload an identical version directly from the computers in the GIS/Data Center (Option 2) or online from this wiki (Option 3). Follow the applicable set of instructions below depending on the particular computer you are using.

...

If you choose to download the tutorial data from the source websites and to practice finding and obtaining data from online sources, follow these instructions:

COHGIS Open Data Portal

The COHGIS (City of Houston GIS) Open Data Portal website provides over 100 data sets including administrative boundaries, amenity locations, transportation routes, crime, and flooding. For this tutorial, we will download population and housing data from the 2010 census, which has been aggregated to super neighborhood boundaries.

H-GAC GIS Census Data

In this case, we are looking for census data by super neighborhood. To learn more about super neighborhoods, visit the City of Houston Super Neighbhorhoods webpage.

...

The Houston-Galveston Area Council (H-GAC) is the 13-county Metropolitan Planning Organization (MPO) for the Houston region. Federal legislation requires that an MPO be designated for each urbanized area with a population greater than 50,000 people (as established by the U.S. Census Bureau) in order to conduct long-range metropolitan transportation planning and be eligible for Federal funding for transportation projects. Their mission to conduct carry out metropolitan transportation planning , means that MPOs are a great source of data on topics such as demographics, employment, land use, transportation, and environmental conditions and most of these topics are well-suited towards GIS analysis.

Most of the data provided on the H-GAC portal is not originally created by the H-GAC, but rather. Instead, the data is either aggregated from multiple municipalities up to the 13-country region, or clipped from the entire country or state down to the 13-county region. For this tutorial, we will download population and housing data from the 2010 census, which has been aggregated to census tract boundaries.

Preparing the Downloaded Data for ArcGIS Pro

Once you have downloaded the Census and Major Roads data from H-GAC and the Bus Stops and Bus Routes data from Houston METRO and the SuperNeighborhoods and Freeways data from COHGIS, you should be able to find locate the data files in your Downloads folder.

1. Open the Downloads folder.
2. Ensure that you see the four folders shown below.

Notice You will see that all the files folders are compressed, or zipped, meaning they contain compressed files of data within them (you , which allows you to download a single ZIP file, instead of numerous individual files. You can tell a file folder is zipped when the file type 'Type' column reads “Compressed 'Compressed (zipped) Folder”). You will need to unzip the folders to be able to see the data inside them. To do that:

1. In your Downloads folder, click in the gray space next to your file path at the top. This should highlight your file path. Right click and copy your file path.
2. Click on one of the data files in your Downloads folder. Once it’s highlighted, right click on the file and select Extract All…
3. For the file destination, right click and paste the file path that you copied in the first step.
4. Click on the Extract button.
5. Repeat this process for however many zipped data files you have.

1. Select all four folders.
2. Right-click any of the selected folders and select 7-Zip > Extract Here.

If you do not have 7-Zip installed:

Managing GIS Data

The full layout of the software will be covered in the Introduction to ArcGIS Pro tutoril. For now, all you will be using is the Catalog pane along the far right side of the application window.

1. In the Catalog pane, click the arrow to expand Folders > Intro > Intro.gdb.

You will notice there is currently no data in the Intro project geodatabase that was automatically created when you created the Intro project. Over the next few steps, you will import the data you downloaded online from the Downloads folder to your project geodatabase.

Connecting to a folder

1. In the Catalog pane, right-click Folders and  and select Add Folder Connection.

Importing and exporting data in the project geodatabase

For this tutorial, we are working with vector data, which is a spatial data format that uses points, lines, and polygons to represent real features on the Earth's surface. Vector data is ideal for discrete themes with definite boundaries. A Feature Class is a vector storage format that represents a homogeneous collection of common features. There are two types of Feature Classes: a Shapefile feature class and a Geodatabase feature class. A Shapefile feature class is an open source format. Its file extension is .shp and its icon is green. A Geodatabase feature class is an Esri proprietary format. A Geodatabase feature class must be stored inside a Geodatabase (.gdb) and its icon is white. To better organize our project, we will import data into our Project Geodatabase.

All of the data you have downloaded is in the shapefile format. Since shapefiles and geodatabases are different file formats, you must convert the data.

1. In the Catalog pane, hold down the Ctrl key and clickHGAC_Major_Roads.shp, HGAC_tracts.shp, METRO_BusRoutes.shp, and METRO_BusStops.shp to select all four shapefiles, as shown below.

3. In the Catalog pane, right-click the Intro.gdb geodatabase and select Refresh.
4. If necessary, expand the Intro.gdb geodatabase. Your project geodatabase should now contain four geodatabase feature classes: HGAC_Major_Roads, HGAC_tracts, METRO_BusRoutes, and METRO_BusStops, as shown below.
