Using the Map

Use the map to find and locate properties spatially. For information on map functionality, see the following topics:

 

 

Using the Tools

You may interact with the map via different tools. Learn about the tools below to be able to use the map effectively:

 

Navigation Tools

Navigation tools allow you to move around within the map. Learn how to use each tool below:

 

Full Extent

A map tool that will automatically zoom to the furthest extent. Zooming to full extent resets the map view so that every feature of every layer is contained within the visible extent.

Steps for zooming to Full Extent:

> Click the Full Extent button in the Tools pane.

 

Previous Extent

A map tool that will take you to your previous view. Zooming to a previous extent allows stepping back through past map views. For example, start with a map view at full extent then zoom in to an area on the map. Now click the previous extent button. The map will return to the most recent map view, which was the full extent.

Steps for zooming to a previous extent:

> Click the Previous Extent button on the Tools pane.

 

Next Extent

A map tool that will take you to your next view. Zooming to a next extent allows stepping forward through map views, if there are any available.

Steps for zooming to a next extent:

Selection Tools

Tools that assist you in selecting features on the map. Selection tools allow you to make queries on features contained within the map. Learn how to use each tool below:

 

Select by Point

A map tool that will select a single feature at the specified coordinate. Use this feature if you are interested in selecting a single feature on the map. In most cases, this tool is used to get information about a particular parcel while browsing the map.

 

Steps for selecting a feature by point:

> Click the Select By Point button in the Tools pane.

> Move the mouse over the map.

> Click a point you are interested in.

 

Note:

The functionality of this feature depends on the active layer. The default active layer is 'Parcels'; selecting a feature on the map by using Select By Point will select a 'Parcel' feature.

Holding the 'Shift' key while making your selection will not erase your previous selection. Use this technique to subsequently add features to your selection.

 

Select by Line

A map tool that will select all features that intersect the bounds of a line. Use this feature when you are interested in a contiguous group of features, but need more control in which features are selected. With this selection tool, you specify a path and all features that intersect that path are selected. This feature can be used to select all parcels of a street segment.

Steps for selecting features by line:

> Click the Select By Line button in the Tools pane.

> Move your mouse over the map.

> Click the map once to start the line.

> Move your mouse to a new location on the map and click again to place the next point.

> Repeat the previous step as many times as needed to fulfill your requirements.

> Double click the left mouse button to end the line.

 

Note:

The functionality of this feature depends on the active layer. The default active layer is 'Parcels'; selecting features on the map by using Select By Line will select 'Parcel' features.

 

Select by Rectangle

A map tool that will select all the features that intersect the bounds of a rectangle. Use this feature if you are interested in selecting a contiguous group of features on the map, or for selecting a single, point-based feature.

Steps for selecting a feature by rectangle:

> Click the Select By Rectangle button in the Tools pane.

> Move the mouse over the map.

> Click and hold the left mouse button.

> Move the mouse to drag a rectangle, creating an area from which you wish to select.

> Release the mouse button to complete the selection.

Select by Circle (Buffering)

A map tool that will return all features within a specified distance of a selected feature on the map. Use this feature when you are interested in finding a set of features within a certain distance of a selected feature.

Steps for buffering:

> The Buffer functionality will return a set of features within a given distance of an already selected feature. The first step is to ensure that you have a feature selected that you want to buffer around. Use the 'Select By Point' tool to select the feature you wish to buffer.

> Click the Buffer button in the Tools pane.

> Type the radius of the buffer (distance in feet) you wish to buffer in the textbox.

> Click 'Go' to perform the buffer. The map will be refreshed and all features of the active layer that fall within the specified distance of the initially selected feature will be selected.

 

Note:

The functionality of this feature depends on the active layer. The default active layer is 'Parcels'; selecting features on the map by using Select By Circle will select 'Parcel' features.

 

Measurement Tools

Tools that provide measuring functionality. Map measurement tools allow you to measure distances and areas of spaces on the map. Learn how to use each tool below:

> You will be prompted by your browser to either open or save the file; choose 'Save'. Save the image on your computer's file system in the desired location.

 

Note:

The type of file the map is downloaded can be either JPG or PNG image file formats. The map engine responsible for rendering the maps on this website chooses which file format is most efficient.

 

Managing Layers

Learn about managing the different map layers. From the Layers tab, you can manage Layer Visibility, choose the Active Layer from the list of Selectable Layers, and view descriptions about each layer. For more information about managing layers, choose from the following topics:

 

Layer Visibilities

Layer visibilities allow you to turn on and off certain layers. One of the things that makes Online Auditor's map different than many online maps (like Google Maps) is the ability to dynamically turn on and off layers. Some layers aren't turned on by default. In the example below, the Soils, Drainage, and Voting Precincts are all off by default. To toggle the layer visibility, click the checkbox in the front of the layer's name.

Steps to toggle a layer's visibility:

> Click the checkbox that corresponds to the layer whose visibility you want to toggle.

 

Note:

Some layers' visibilities are scale dependent. You cannot manage the visibilities of these layers until you are within the visible extent of the layer. In the example above, the Parcels layer is scale dependent. The checkbox is disabled because the map is not zoomed to an extent at which the layer can be visible.

 

Selectable Layers

Selectable layers are layers that have the ability to be the active layer. When selecting features on the map, the layer that the features are selected from is called the Active Layer. The Active Layer is selected by clicking on the layer's label. Not all layers are selectable, however. Selectable Layers have blue text. The Active Layer is highlighted in light blue. In the example below, the Parcels, Soils and Voting Precincts are selectable layers and the Parcels has been selected as the Active Layer.

Steps for selecting the Active Layer from the list of Selectable Layers:

> Click on a Selectable Layer.

 

Note:

There can only be one Active Layer selected at a time.

 

Layer Descriptions

Layer descriptions are captions about the layers. Not all layers have descriptions. If a description is available for a particular layer it will have an external link image after the layer's label. Click on this image to read a description of what the layer represents and how to best view the layer. In the example below, only the Parcels layer has a description.

Steps for getting a layer's description:

> For the layer you are interested in, click the 'descriptions' image that appears after the layer's label. A description of the layer will be displayed in a modal pop-up box.

 

Making and Viewing Selections

Learn how to make selections. Selections are made on the Active Layer. In most cases, the Active Layer is the Parcels layer; you make Selections to obtain information for a parcel you see on the map. Visit the Selections section for more information about using different Selection tools.

Steps for viewing selections:

> Once you've made a selection, information on the selected features will be returned to the Selection table (seen above).

> If the feature is a parcel, you can view all the property's Data by clicking the parcel number.

> If you want to zoom to a particular feature, click on its Feature ID.

 

Using 'Zoom To:' Functionality

Learn how to use 'Zoom To:'. You can conveniently zoom to a specific area of the map using Zoom To. Features you can usually zoom to are cities/towns, schools and parks.

Steps to zoom to a specific area on the map:

> Locate Zoom To at the bottom of the map.

> Choose the type of feature you want to zoom to. Usually you can choose to zoom to a city/town, park or school.

> From the dropdown list, choose the name of the feature you want to zoom to. This will center the map on the selected feature and zoom to its appropriate extent.

 

Viewing Oblique Imagery

Learn how to view oblique imagery (not available on all Online Auditor websites). Oblique Imagery is an exciting new technology made possible by Microsoft Virtual Earth and Pictometry. Oblique images are high resolution views of earth's surface at a slight angle where objects can be viewed from each direction. To learn how to view oblique imagery on this website, read from the topics below.

 

Viewing Oblique Images

The oblique imagery window will only be displayed once you have zoomed in past a certain extent. This way, the detail shown in the oblique imagery matches the detail shown on the main map. Once the oblique imagery window is displayed, additional tools are available.

 

Changing Direction

You can view objects from each of the four directions. Click 'N', 'E', 'S', 'W' to view north, east, south and west directions respectively. Note, clicking 'N' will show you the south side of any objects in the image because you'd be looking north.

 

Zooming In

Two zoom levels are available in the oblique imagery window, 'Out' and 'In'. The default zoom level is Out.

 

Launching Interactive Mode

Click 'I' to launch Interactive Mode. Interactive Mode will pop up a new, larger window and allow you to use more advanced tools to interact with the map.
