The Public Safety application provides police incident results information to the general public and other interested parties.

Using the Application

The Public Safety application offers a simple interface for users to discover police incidents. In the interest of performance when you first open the application you are presented with a blank map. Simply click the blue SEARCH button to view data

Searching Incidents by Date

On the right side of the map is a Search Window. By default the date range is set to search for the previous 7 days. You can set the date range back as much as 10 years but the map will only return the first 500 records. This limitation is set to maintain performance.

Don't include search results that fall outside of the current map window

This checkbox allows the user to narrow their search results using the extent of the current map window. By default, the search tools will return every record it finds within Midland County. If you check the box you will only receive records back that fall within the current map extent.

Choose offenses to search for

This tool allows the user to pick and choose the offenses to search for. By default the search tools will return all results. To search for specific offenses simply uncheck the boxes next to the codes you don't want to search for. Any checkbox with a check in it will be included in the results.

Map Based Navigation

There are several ways to interact with the map:

1. Hold down the shift key and drag a box on the map to zoom in
2. Hold Down Ctrl + "-" to zoom out
3. Hold Down Ctrl + "+" to zoom in
4. Roll your mouse roller to zoom in/out
5. Click on any incident icon to view its details
6. Click on any row to the data table to zoom to the incident on the map


Heat Map

What is a heatmap? You've never heard of heatmaps? No problem! In short: a heatmap is a graphical representation of datapoints with different frequency, usually red spots on a heatmap are highly frequent spots and blue ones are less frequent spots. The heat map in this application is produced using a script from heatmap.js. The code used to generate the heatmap comes from http://www.patrick-wied.at/static/heatmapjs/ The heatmap.js library is currently supported in Firefox 3.6+, Chrome 10, Safari 5, Opera 11 and IE 9+.

Browser Compatibility

The application has been tested on i.e 8 and 9 and Firefox
**Please note, there is a known bug in Google Chrome that prevents the map from zooming to a select record**
