Supply Level
The Analysis Power Supply in the menu area organisation shows the degree of coverage of an area by the existing locations. you visualizes the ranges of the locations. The capacity of the locations as well as the distribution of the data over the area. The analysis shows which areas of more than one location (= oversupply) and which areas are not served by any location. (= undersupply).
As a basis for calculating the coverage rate you can also select the distance to location instead of a data column. With this you have e.g. quickly answers the question:
Which areas are located within a 100 km radius of at least one Location?
Example
The figure below shows in red areas that are not sufficiently supplied by the existing locations, while in turquoise oversupplied areas are shown. The presentation is based on the assumption that each site aims to exploit the potential in the surrounding area and extends its catchment area until the capacity limit of the site is reached. Naturally, they remain unsupplied far from the site, unless they are reached from another site. Where locations are too close to each other, there are areas that can be well supplied from several locations. Such a supply level analysis provides information on how well or how badly the locations are distributed over the area.
Creating the Analysis Supply Level
You can access the analysis via the menu Territory organization > Analyses > Performance level. First, you are asked at which level or at which locations the service areas are to be calculated.
Alternatively, in the control window Territory organization you can also insert the analysis coverage level in the context menu of the area or site level under analyses.
Selection of the data basis
In the next step, select the Map in which the analysis is to be displayed and the Layer on the basis of which the coverage level is calculated. The basic building block level and all subordinate area levels of the territory structure can be selected as levels.
Then click on Complete and EasyMap will insert a first draft of the distance zones into the map.
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.
- What does the assignment result tell you?
- Would you like to place your data on the map using geographical coordinates? So the The Data Input for an Analysis.
- The Advanced button allows you to specify whether the analysis should consider an existing clip map when calculating classifications - more on the analysis reference.
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 Power consumption.
Calculation of the supply rate
In this analysis, similar to the analysis surface coloring, the column to be analyzed can be selected. The default setting here is the data column area. Under Statistics you will find various indices for the selected column.
Important for this analysis is the setting of the capacity of a location. The value indicates how many areas in the vicinity of a location are considered to be supplied. Starting from the location and sorted by distance, all areas are collected until the cumulated total exceeds the capacity of the location. If "(distance to location)" is selected as the data column, the capacity is understood as a distance value that must not be exceeded. Depending on the data column selected, the capacity value in the Calculation range must be adjusted (see figure on the right).
class formation
The areas of the brick level of the selected level can be colored here classified, by forming classes. 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.
In the middle area, enter Classes, the Count for classes, and the method of automatic Classification or set here to User defined to edit your own classes. In addition to Analysis range, you can also specify an interval within which the values are to be taken into account. Values outside the interval always fall into the residual class "unclassified".
- In the area of the class list you can determine details of the analysis. Various commands are available here to edit classes and colors.
- The design characteristics and class boundaries can be edited by double-clicking in the relevant cell. For example, you can select the color individually by double-clicking on the color of the class.
- For more information on editing classes, symbols, colors and sizes, see here.
Note: By sorting according to the name of the class, you can force a certain order in the legend!
Determine the details of the analysis
In Details you define other (non-data-dependent) properties of the analysis.
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 | |
Distance calculation |
No: Optimization is based exclusively on the airline distance Fastest journey time (car): Optimize your properties according to the fastest travel time. The values of a standard car are taken into account. Note: The available options are determined by the license you have purchased. This function is only available if you use the extensioneasymap office pro or easymap professional. For each object drawn, credits are deducted from your quota. The more data records your table contains, the more credits will be deducted. Shortest travel distance (car): Your properties are re-optimized taking into account the shortest route. The values of a standard car are taken into account. Note: The available options are determined by the license you have purchased. This function is only available if you use the extensioneasymap office pro or easymap professional. For each object drawn, credits are deducted from your quota. The more data records your table contains, the more credits will be deducted. Consider geographic barriers (e.g., bodies of water, mountain ranges, state borders): 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 . |
