Catchment Areas

With the analysis Catchment areas in the menu Territory organizationyou can analyze how much potential your locations have within certain distances. open up. In contrast to the analysis Distance zones the distribution of the potential around the locations will also be are taken into account.

The result representation in the map resembles a Target: It shows in which zones around the site there is a certain potential is opened up. Zones that are close to the site indicate, on the one hand, the following a territory with a high potential, on the other hand to a territory within the Territory well chosen location.

To evaluate the catchment areas, absolute or Use percentages. Absolute numbers are more suitable for the absolute Comparison of the territories among each other.

If percentages are used, the following meanings apply The catchment areas of the sites show that a certain percentage of the potential of the existing territory. This valuation variant is suitable for to the separate consideration of each territory.

Are the territories balanced according to their potential (i.e. ), there is hardly any difference between the two variants.

Creation of the analysis catchment areas

The analysis can be reached via the menu Territory organization > Analyses > Catchment areas. First, you are asked at which level or at which locations the catchment areas are to be calculated.

Alternatively, you can also insert the feed areas in the control window area organisation in the context menu of the area or location level under analyses.

Select data input and connect the data to the map

For your analysis, select the appropriate assignment between data and levels and confirm your selection.

Edit Properties

Immediately after inserting the analysis, the Properties on the right side of the program window open (default setting). The properties can be reopened at any time via the control window Content by double-clicking on the map layer Catchment areas.

Determine the colouring of the catchment areas

In this analysis, similar to the analysis surface coloration, the data column to be analyzed can be selected. The default is the column Area. Under Statistics you will find various codes for the selected column. The zones around the site can be colored here classified by the formation of classes with increasing distance to the site.

Comparability of territories

Choose between Global evaluation (absolute) or Territorial evaluation (percentage) to either compare the territories with each other or to display separate, district-related catchment areas.

Classified data evaluation

The creation of classes offers you numerous setting options. In addition to the number of classes or move-in areas, you can also define how the limit values of the classes are to be determined.

Determine the details of the analysis

In Details you define other (non-data-dependent) properties of the analysis.

The following properties are available:

Visibility
General	Here you can control the visibility of objects and elements.
Scale range	Here you can set whether the selected object or plane should be visible at each scale. Or you can specify the scale or zoom level at which the object or layer is visible.
In reports	In Reports there is the possibility to change the environment only partially to zeigen. You can use this property to specify whether the layer is also visible outside the report area in this case.
Alternating visibility group	Set a group for mutual visibility here. If the element is to be made equally visible with other elements, you must use the same name for the visibility group.
Simultaneous visibility group	Set a group for simultaneous visibility here. If the element is to be made mutually visible with other elements, you must use the same name for the visibility group.
Calculation
Missing data	Don't calculate the result value: Only for bricks for which data is available is a result value of the analysis calculated. This selection can lead to results where only individual areas are colored. Treat as 0: Bricks for which there is no value are also included in the analysis. Their value is treated as 0. As a result, such areas may well get a value greater than 0. This selection leads to area-wide coloured maps.
Use geographic barriers	Specify whether EasyMap calculates the distance of a brick to the territory location using the linear distance or whether it additionally includes topographic obstacles (barriers) such as mountains, rivers or bays in the distance calculation. These are read from Barrier-base map
Common
Type of Shading	Here you can select whether the color of the areas full area or only as edge color should appear. With this option, loosened maps are possible, which allow not only the analysis of the surface coloration but also a further evaluation, without the map appearing overloaded and not really readable.
Width of the Colored Border	Here you can set the width for the edge coloring in cm .
Comment	Enter here a comment for the display of the workbook in EasyMap Xplorer. The comment is also displayed in EasyMap as a tooltip in the control window Contents.
Hatching - Display of the distance zones with multiple assignment.
Type	Here you can choose the type of hatching.
Width	Set here the hatch width in pixels.

Create tooltips for analysis

When crossing the colored areas on the map, you can display context-sensitive information about them.

Note: You can find out how to implement tooltips here.

The commands of the context menu

You can right-click on the analysis in the control window Content to open its context menu. The context menu provides actions that can be performed on this analysis.

List of commands in the context menu

Transfer Selection to	Transfers the current selection geographically to another object. Details...
Visible	Shows whether the object is visible and allows switching the visibility.
Order	Here you can change the selected element in the character sequence. Another option is to drag and drop the selected element within the content view.
Input Data...	Displays the data settings for the selected analysis. You can use this command later to change the connection between the analysis and the data. Further information can be found here.
Show Results Table	Displays the results of the selected analysis in a table.
Ignore filter	Defines whether an Analysis filter should be considered or not. This setting only has an effect if Apply filter to analyses is activated in the table on which the analysis is based. In this case, Ignore filter can be used to exclude individual analyses from the filter application.
Restore defaults	Undoes all manual changes to this layer.
Clip Map	Here you can define a different clip map for the analysis.
Map XY	Here you will find various commands for the Map.
Copy	Copy the object (if necessary with all subobjects) to the clipboard to paste it elsewhere. The object can be inserted in other applications as a graphic, or inserted in EasyMap as a copy of this object using the Insert command.
Paste	Pastes the contents of the clipboard into this object as a child object.
Delete	Deletes the selected element. (See also: delete objects)
Rename	Changes the content view to an edit mode to give the object a new name. (This can also be achieved by clicking on an object that has already been marked.)
Properties...	Opens a properties dialog in which you can edit the Properties of the selected object. If several objects are selected, many properties can also be changed simultaneously for these objects.
