Using this Manual
The purpose of this manual is to guide you through the many tools and features contained in these four GIS applications (App Community, App Demographics, App Development and Crime Map Viewer). To find instructions on any of these features, click on one of the icons at the top. Please note some tools are not available in all applications. For example, the 'Demographics' button is available only in the 'App Demographics' application.

These applications work best work with Internet Explorer 8 and Firefox 3.6.10. The applications also use Microsoft Silverlight technology, which is similar to Flash, therefore, you might be prompted to download and install the latest Silverlight plug-in. This is a simple and automated process, and requires very little interaction from the user. Adobe Acrobat Reader is also required to view any demographics reports.
Navigation Control
The Navigation Control is a single tool allowing you to move and zoom in to any portion of the map. It has many of the same features as the Navigation Toolbar at the top right.
  • With the vertical bar on the left you can enlarge (zoom in) or reduce areas (zoom out) of the map by moving the slider or clicking on the plus or minus symbols.
  • The triangles in the circle pans to the four compass directions
  • The triangle at the bottom left reorients your view to North
Aerial Map Layer
Click to display an aerial photographic view. This image will occupy the bottom layer of the map to allow all other map features (roadways, parcels, points of interest, etc.) to overlay on top. The slider can be adjusted to increase or decrease the transparency of the aerial photo.

City Demographics
The Demographics tool, available only in the City Demographics application, builds downloadable reports based on selected areas or locations on the map. Clicking on the button will load the panel with a dropdown list of categories to choose from.

Select the Demographic report
Please pick the type of information you want about an area in the city. Click on the top button as seen above and select the report that provides the information you want. Moving your cursor over the report will provide more information about each report
Selection Icons
Use any of the left three icons to define a specific area on the map. Use the freehand and polygon tool to surround a specific area, and the square for a more general one. With the chosen tool, draw an area around a part of the City of Tracy. Once the area has been chosen (in red), the report will start to process (processing time may vary depending upon type of report and selected area). You should see a description of the report progress toward the bottom of the screen (see below for an example). Once the report is complete a Download Report button will appear in the panel. The report will be in an Adobe Acrobat format. Click the Download Report button and a new window will open the report for you.




Drive Time and Simple Ring (distance) Analysis
Before clicking on the drive time or simple ring analysis, please pick the demographics report you want to run. As with the previous selection tool, the report will process once you click either the drive time or simple ring analysis. The Download Report button will appear when the report is ready.

Note: The drive time (minutes) and distance (miles) have preset default values for these tools. You can change those parameters by clicking on the Options icon (see next item down).

The Drive Time (car) and Simple Ring (flag) will create a 3-zone concentric shape or circle, depending upon the time and/or distance chosen. Selecting the car icon and clicking on a specific point on the map will display areas defining driving time, in minutes, from point of origin to the drive time distance within the three areas. Demographic information will be analyzed for each of the three drive time areas.

Likewise, by using the flag in the same manner, concentric rings will radiate out in miles from a point of origin. Demographic information will be analyzed for each of the three areas based on the determined distance from the flag location.
Options
With this feature you can change the minutes and distance values for the drive time and simple ring analysis tools above by clicking the up or down arrows in the panel. If you want just a single zone, set all three zones or rings to the same number.
Disable/Clear
And finally, to reset and clear the map, simply click this icon and you are ready to run a new scenario.
Map Layers
Select any combination of layers to display on the map.
  • Turn on/off layers by clicking check box. The layers will turn on after you check the box. No other action is necessary.
  • Expand layers by clicking the adjacent corresponding triangle.
  • Grayed out checkbox means that layer is unavailable at this view but will become visible by zooming in further.
  • Opacity of certain layers (Basemap, Aerial) can be adjusted by moving the slider at the right of the listed item.
Search

This tool will perform a search based on an assortment of categories and criteria. Select one of the Search items in the dropdown list. 

Usually you can enter the first few letters or numbers of the location and a dropdown list will open with any related possibilities. Just select the one that matches and click the Search button.

The tool will perform a search and zoom to that specific record and will also show the Property Information as shown below.






Search Type Description Sample
Address Type in an address to search 475 E 10TH ST 95376
Property APN Type in the APN value 23519013
Parks Type in the Park Name Eagan Family Park
Subdivision Type in the Subdivision Name Summergate
Schools Type in the School Name Saint Bernard
Points of Interest Select any value from the pull-down menu


Search using Address Locator

Sometimes the Parcel Address Database might not contain the exact matching address. Under these circumstances the application will search in the Address Locator and come up with a list of possibly matching addresses. The snapshot shown below explains how an address search can yield all possible matching addresses and the score as well. 





Points of Interest Search

This is a special kind of search where the user can select the choices from the pull-down menu. The tool will display name, address and the phone numbers as shown below. 





Crime Map Viewer Search

The search tool for the Crime Map Viewer application looks and works differently than the others by allowing you to search for types of crime based upon selecting one of three options. The results display as map symbols representing different types of crime, which are defined by activating the Map Layers.

Search Crimes by Date

You can search by a specific date, or a date range, by entering values in the text fields or selecting dates from the adjacent calendar icons, then clicking on the Search button. Symbols representing different crime types will then appear on the map.



Search Crimes by Address

Enter a specific address then hit the Enter key. The map will zoom to the address location and display a list of closely related addresses.



Search Crimes by Type

After performing a Search by Date or Search by Address, selecting the "Search by Crime Types" will display a list box of crime categories. Clicking on one or more types will highlight specific crimes on the map with a red and yellow pulsating dot.


Tools
Below is a list of the available tools.

Measure Tool
With this feature you can find the distance between two points, or the approximate total area of a location. As an example, to find the approximate total square feet of a parcel, click the radio button in the panel marked Measure Area. Then single-click on points on the map to draw a shape surrounding the parcel. Double-click at the last point to finish. Results will appear at the lower left of the map.

Follow the same procedure to measure distance, but just click on the starting point, then double-click the end point.

Note: You can set the unit of measure to feet or miles by using the Measure Units tool below.


Measure Units
This applies to the Measure Tool above. Sets units to feet or miles.




Property Info Tool
Displays some basic information about a parcel and other related information. The Property Info tool can be used to get information from parcels, schools or parks. Select the tool from the popup list, and then click on a parcel. A panel, similar to the one below, will appear with information. Clicking on the '+' sign will expand the row and display more information.



When clicked on a Park or School, the Property Info tool will display additional information including photos. The snapshot below shows the picture of a park.



Google Street View
To see a street view, select this item from the menu, then click on the desired map location. A separate window, like the one below, will open





Clear Selection
