User Manual
Map Layers
In the Map Layers menu, the user can control the layers that are displayed on the map - enable/disable the display of layers and change their style. The base map is always below the other layers, next one is the Coverage layer. The order of other layers can be changed.
Figure 39. Map Layers
- Add a new custom layer from KML or CSV file.
- Move the selected layer up.
- Move the selected layer down.
- Change the style of the selected layer (or double click on the selected layer).
- Delete custom layer.
- Show the first point of the selected user layer in the center of the screen.
By default, the following layers are always present: sites, PtP links, PtMP base stations, subscriber stations. The user can change their order, turn on / off, and change the style of the layers, but it is impossible to delete them.
Custom Layers (KML, CSV)
The user can load and display as a layer on the map any point or linear vector objects in KML format. This may be, for example, power lines, pipelines, and other infrastructure objects.
Point objects can also be downloaded from a CSV file (text format, where the separator is a semicolon).
This is a universal format in which you can save a spreadsheet from any spreadsheet editor (Excel, LibreOffice Calc, and others), as well as databases.
The required fields for each point object are Parameter, Latitude, and Longitude. Format coordinates - HEMISPHERE degrees minutes seconds (N35 23.8 36) or HEMISPHERE decimal degrees (N12.34567). As a parameter, there can be any text that appears at the point with the specified coordinates. This may be, for example, the measurement result or the name of the object.

Step of Terrain and Obstacle Points along the Profile, m
The step of terrain and obstacle points along the profile for automatic creation of the path profile.
For SRTM-1, the minimum step for creation of the path profile is 30 m. A lower value makes no sense since it will not increase the accuracy.
Part of first Fresnel Zone which will be Shown, %
A part of the first Fresnel zone which will be shown when the path profile is displayed.
Median Value of K-factor
The median value of the k-factor that will be used to create the link path profile and determine clearance

Path to Folder with Cache Files
The path to the folder where downloaded base map tiles will be saved for quick access. This will speed up the application. The downloaded maps will remain on your computer and you will be able to view them when you do not have an Internet connection. This folder is created automatically when the application is launched for the first time. You can change this folder.
Path to Folder with Data Files
The path to the folder where the downloaded SRTM and forest data files will be saved for quick access. This will speed up the application. Moreover, the downloaded files will remain on your computer and the application will be able to use them and create a terrain profile when you don’t have an Internet connection. This folder is created automatically when the application is launched for the first time. You can change this folder.
Proxy Settings
If you are using a proxy server to access the Internet, enter its IP-address and port number. If the proxy server requires authentication, enter the username and password.

Basemap Settings
You can configure your own custom base map by specifying a tile server URL.
The prototype URL encapsulates a request format that is specific to the map provider and it varies from map provider to map provider. It consists of a text string that begins with http://, has a domain name and possible parameters, plus some symbols that MLinkPlanner substitutes with real-time tile request information when actually contacting the server.
Below is a detailed explanation of how prototype URLs are constructed. The possible symbols that MLinkPlanner accepts in the prototype URL are: [X], [Y], and [Z] coordinates and zoom.
To lookup map imagery in their database, most map providers use tile coordinates of x and y, plus zoom. As an example, the OpenStreetMap provides map imagery using x, y, and zoom. We can test-fetch a map tile of a portion of North America by typing the following URL into a web browser:
http://a.tile.openstreetmap.org/3/1/2.png
The numbers at the end of the URL represent zoom, x, and y, respectively. The OpenStreetMap fetches the map tile corresponding to x = 1, y = 2, and zoom = 3.
In order for MLinkPlanner to properly fetch tiles from a map provider, a generalized prototype URL scheme must be furnished. This generalized URL scheme will be used by MLinkPlanner to fetch any tile, at any coordinate, with any zoom. To accomplish this, the symbols "[X]," "[Y]," and "[Z]" (without the quotes) are inserted in place of explicit coordinates.
For example, creating custom map types in MLinkPlanner for OpenStreetMap can be accomplished by mixing the known explicit URLs above with the symbols representing x, y, and zoom to form a custom map prototype URL (try these in the custom maps setup screen in MLinkPlanner):
http://a.tile.openstreetmap.org/[Z]/[X]/[Y].png
When MLinkPlanner needs a map tile fetched from a provider, it will replace the "[X]," "[Y]," and "[Z]" symbols with the actual coordinates and zoom for the tile required and then use the resulting URL to contact the map provider's server to fetch the map tile.
