Using Zoom Layering In MapInfo Pro

MapInfo Pro 32/64-bit

What does the Zoom function in a map do?

Zooming allows you to look more closely or more widely at a particular geography. Zoom Layering allows user to control the visibility of each layer based on whether it is relevant for the current map window zoom. 

How is Zoom useful?

The fixed zoom factor determines how much the map is zoomed out so the geometry or feature is visible. For example, a detailed streets layer is best used when you are zoomed in close on the map. A generalized (i.e. not detailed or low resolution) boundary layer is best used when zoomed out.

What is the purpose of Zoom In?

It provides a closer area view of a Map or Layout window.
 

When is Zoom In active?

How to I access Zoom In?

What is the purpose of Zoom Out?

To display a wider area view of the current Map or Layout window.

What is zoom layering?

Zoom Layering allows you to control the visibility of each layer based on whether it is relevant for the current map window zoom. For example a detailed streets layer is best used when you are zoomed in close on the map. A generalized (i.e. not detailed or low resolution) boundary layer is best used when you are zoomed out.

Determining the Zoom Layering settings:

Here are quick tips for knowing if Zoom Layering has been applied to a Layer and what these settings are.

Tips for zoom layering


Setting the Zoom Layering

To set the Zoom Layering you need to access the Layer Properties dialog box. Here are two ways to do this. In Layer control either (1) Select the Layer and click the Layer Properties button or (2) double click the layer name.

The Zoom Layering controls

See the screen shot below. The minimum zoom can be used to prevent layers from being displayed because they are too general. The city layer below is a good example. Let’s say you have a layer of cities and towns which are represented as points. If you zoom in to a very small area, let’s say a few hundred meters, then the whole area of your map represents the city. When zoomed in this close it no longer makes sense to display a point to represent the city.

Work with multiple layers at once

If Zoom Layering is required to change (or other Layer Control settings) it is possible to select multiple layers and change them all at once.
