You will now work with a dataset containing the locations of all violent crimes (including murder, rape, aggravated assault, and robbery) occurring in 2010, as reported by HPD. Though the data has been pre-processed for this tutorial, the original data tables can be obtained online from the Houston Police Department Crime Statistics webpage at httphttps://www.houstontx.gov/police/cs/stats2crime-stats-archives.htm.

1. On At the right side bottom of the screen, close the Geoprocessing pane, click the Catalog tab.
2. In the Catalog pane,  drag right-click the HPDCrime2010 feature class into the Map Display.and select Add To Current Map.

The crime layer may take a while to load and appear in the map view. You will now clip the crime layer to the study area boundary to reduce the size of the dataset.

...

1. At the bottom of the Catalog pane, click the Geoprocessing tab.

Notice that the Geoprocessing pane always displays the parameters of the last tool that you ran. Since you want to run the clip tool a second time and will be clipping to the same HISD extent as in the previous run, it is quicker to modify the existing parameters than to click the back arrow and launch the clip tool again from scratch.

1. For ‘Input Features’, use the drop-down menu to select the HPDCrime2010 layer.
2. For ‘Clip Features’, use the drop-down menu to select the HISD layer leave the default HISD layer selected from the previous run.

Even though the clip process itself will only take a few seconds, it may again take a couple minutes for the new layer to display on the map view.

1. In the Contents pane, right-click the HISDCrime2010_HISD layer and select Attribute Table.

In this tutorial, you navigated to various geoprocessing tools directly through the Toolbox; however, it is likely that when you go to work on your own, you may not remember exactly where all those tools are located.  As long as you can remember the name of the tool or what it does, you can find it using the search function.

1. On the Analysis tabAt the top of the Geoprocessing pane, click the Tools  the Back arrow button.
2. At the top of the Geoprocessing pane, in the Search click the Favorites tab.

This tab shows five commonly used tools, along with all the tools you have run recently and any tools you have marked as a favorite by right-clicking on the tool name and selecting Add To Favorites.

1. In the 'Find Tools' search box, type “Buffer”  “Clip” and press Enter Enter.
2. Click on the first tool that says Buffer Clip (Analysis Tools) to open the tool parameters.

Reviewing Tool History

1. At the bottom of the Geoprocessing pane, click the Catalog tab.
2. At the top of the Catalog tab, click the History tab.

Within the history tab, you will see a complete list of all of the tools you have run in order. Double-clicking on any tool in the history will reopen the tool with the exact settings used in the run. This is a great way to review previous work for documentation purposes or to rerun a set of tools or slightly modify a setting with minimal thought.
