FSX KML

Introduction

Before and after screenshot

FSX KML is a freeware scenery design tool for Microsoft Flight Simulator X (FSX).

It converts KML (Keyhole Markup Language) files generated by Google Earth into FSX scenery.

Using Google Earth to draw polygons and polylines you can accurately and easily create the following types of "vector" based scenery:-

• Water polygons including oceans, rivers, lakes and canals
• Islands inside water features
• Irregular shaped landclass polygons for cities, parks, beaches, forest, golf courses etc
• Airport polygons
• Flatten polygons
• Shorelines along water polygons
• Streams
• Roads, including roads with moving traffic
• Utility lines (eg power and telephone lines)
• Exclusions polygons

Additionally FSX_KML can also:-

• Place scenery objects (from the FSX library) along a polyline
• Create landclass and waterclass “tiles” (1.2km sq)
• Create a FSX flight plan along a polyline

Downloading FSX KML

The latest version of FSX KML can be downloaded from the following sites:-

Installation

Installing FSX KML

FSX KML can be installed in a folder of your choice. Simply unzip the FSX KML installation zip file into the desired folder.

After unzipping the installation file you should have the following files:-

• FSX_KML.exe
• ShapeLib129.dll
• FSX_KML_TAGS.XML
• Tutorial.KML

Installing the FSX Software Development Kit (SDK)

To use FSX KML you will need the FSX SDK. If you purchased the deluxe version of FSX then you already have the SDK. Otherwise you must download the SDK from the Microsoft FSX website

If the SDK is not installed in the default SDK folder you must specify its location on the FSX_KML build tab.

The Tutorial

FSX KML includes a simple tutorial to get you started. This tutorial demonstrates the creation of a coastline (with beaches), a river and islands, a town and forest, plus a road with moving traffic.

• Open Tutorial.KML in Google Earth. An easy way to do this is to double click on Tutorial.KML in windows explorer. You will see the various polygons and polylines that have been "traced" over the real scenery features displayed in Google Earth. The important thing to notice is the use of the "Description" field for each polygon or polyline. The description field is used to tell FSX KML what type of scenery feature the polygon/poyline represents. These tags be customised in FSX_KML_TAGS.XML
• To make scenery from the Tutorial.KML file:-
  • Run FSX KML
  • On the project tab, click "Add KML" and select "Tutorial.KML". You will see KML structure displayed in FSX KML
  • Click the Build tab, and then click the Build button. FSX KML will create a FSX scenery file called cvxTutorial.BGL. The file will be copied automatically to the FSX addon scenery directory
• To test the scenery:-
  • Run FSX
  • Open the saved flight called "Tutorial.Flt"

Building Scenery

Building your own scenery with FSX KML is easy.

Step 1 - Creating a KML file with Google Earth

The first step in creating your FSX scenery is to create a KML file by using Google Earth to "trace" scenery features.

Creating polygons and polylines

Although you can use the free version of Google Earth (GE), by far the easiest way to create polygons and polylines is by using the $20 plus version of GE.

Using GE Plus create a polygon using the "Add Poly" function or create a polyline using the "Add Path" function, and then trace the scenery feature (for example a lake or road).

"Tagging" the scenery features

To describe what scenery feature your polygon or polyline represents it needs to be "tagged". The file FSX_KML_TAGS.XML contains a list the tags you can use.

There are two ways to tag a polygon or polyline:-

• Place the name of the tag in the description field of the polygon or polyline
• Place the name of the tag in the description field of the parent folder that contains the polygon or polyline. If a polygon/polyline has no tag then it will inherit its tag from the parent folder.

Step 2 - Processing the KML file with FSX KML

The Project tab

The Build tab

• Run FSX_KML
• On the "Project" tab, click the "Add KML" button and choose a KML file. The contents of the selected KML file will be displayed. You may add multiple KML files. A FSX BGL file will be generated for each KML input file.
• Change to the "Build" tab
• Set the following build options:-
  • "FSX folder" - Input the folder where FSX is installed. By default this is "C:\Program Files\Microsoft Games\Microsoft Flight Simulator X"
  • "Shp2Vec" - Input the location of the SDK tool Shp2Vec
  • "Run SDK tools" - If you select this option FSX KML will automatically run the SDK tools to turn your Shape Files into a FSX BGL
  • "Copy generated scenery to FSX Addon Scenery Folder" - If you select this option FSX KML will copy the generated BGLS to the FSX addon scenery directory
• Click the "Build" button. FSX KML will now build your scenery. The progress of the build will be displayed in the build log window. The following actions will occur during the build:-
  • For each KML file in your project
    • An appropriate set of Shape files is generated depending on the features that have been tagged in the KML
    • An XML config file is created for use by Shp2Vec
  • A batch file called "Run_SDK_Tools.bat" will be created. This batch file contains the appropriate commands to call the SDK tools (Shp2Vec and Resample)
  • If you have selected the "Run SDK Tools" option then the Run_SDK_Tools.bat file will be executed. This will turn the Shape files into BGL scenery files
  • If you have selected the "Copy generated scenery..." option then the BGL files(s) will be copied to the FSX addon scenery directory

Step 3 - Testing the scenery

• If you selected the "Copy generated files..." option then your scenery will have been copied to the FSX addon scenery folder. Simply run FSX and goto your scenery location to test the scenery

Scenery Design Tips

Creating a coastline with beaches

• Draw a polygon representing the ocean. "Tag" it with a ocean water polygon tag
• Draw a polygon representing the beach. "Tag" it with a sand landclass polygon tag

Creating a road with moving traffic

• Draw a polyline to represent the road. If your road is going to have "one way" traffic then the traffic will travel from the start of the line (1st point you draw) to the end of the line (last point you draw)
• "Tag" the polyline with a road polyline tag
• "Tag" the polyline with a traffic polyline tag

Creating a river with islands

River with islands

• Create a folder in your KML to hold the river
• Draw a polygon representing the river. "Tag" it with a river water polygon tag
• Create a sub folder to hold the islands. "Tag" it island with the special "ISLAND" tag
• In the sub folder draw polygons for each island in the river

Creating a bush landing strip

Standard airports in FSX always appear flat and without sloping runways. But there is an easy way to create sloping bush landing strips using landclass polygons.

• Draw a polygon that will represent a grass clearing. "Tag" it with a grass landclass poly tag
• Draw a smaller polygon inside the first one that will represent the landing strip. "Tag" it with a dirt landclass polygon tag

Creating exclusions

Because your scenery is added to the existing FSX scenery it is important to exclude existing scenery features that are replaced by your new scenery. For example, if you have created an improved version of a river using water polygons you will need to exclude the existing water polygons in the FSX scenery, otherwise they will clash visually with your new scenery.

For example, to exclude water polygons:-

• Draw a polygon that covers the area you wish to exclude
• "Tag" the polygon with a waterpoly exclusion tag

FSX_KML_TAGS.XML

FSX_KML_TAGS tab

What is the FSX_KML_TAGS file?

This file holds the "tags" that are used in the KML file to describe FSX scenery features. You can customise this file to add more tags or change existing ones.

An easy way to browse this file is by clicking on the "FSX_KML_TAGS.XML" tab in FSX KML.

This XML contains the following attributes for each "tag":-

• Tag - The unique identifier for this scenery feature. This tag is what you use to "tag" the polygons/polylines in your Google Earth KML file
• Description - A description of the scenery feature. This description is displayed in FSX KML.
• Feature Type - The type of scenery feature and must be one of the following types:-
  • WATERPOLY - Water polygons such as coastline, rivers, lakes, canals etc
  • PARK - irregular shaped landclass polygons for towns, forest, beaches, park etc
  • AIRPORTBOUNDRY - define airport boundries and also flatten areas
  • EXCLUSION - exclude default scenery from the polygon
  • STREAM - create streams
  • SHORELINE - create animated shorelines
  • ROAD - create roads and road bridges
  • FREEWAY - create moving traffic
  • RAILWAY - create railways and rail bridges
  • UTILITY - power lines, telegraph lines, fences etc
• GUID - The FSX GUID for the scenery feature.

Please refer to the FSX "terrain.cfg" file and terrain SDK documentation for futher information on feature types and GUIDs
