There are a couple different ways of creating shapefiles for terrain. Here is an overview and hopefully it will help those understand the scenery process a little bit better. | There are a couple different ways of creating shapefiles for terrain.

=== === Creación del terreno | |||
Hay un par de maneras diferentes de crear shapefiles de terreno. He aquí un resumen y espero que ayudar a las personas entender el proceso de escenario un poco mejor. | |||

This method has been used for St. Maarten in the World Scenery and Rio de Janeiro custom scenery. In this way, you download a satellite photo or an aerial photo and create the shapefiles by hand by "drawing" on top of the photo. | This method has been used for St. Maarten in the World Scenery and Rio de Janeiro custom scenery.

{{Artículo principal | Howto: Crear un paisaje personalizado}} | |||
Este método ha sido utilizado por San Martín en el escenario mundial y Río de Janeiro escenario personalizado. De esta manera, se descarga una foto de satélite o una foto aérea y crear los shapefiles a mano por "dibujar" en la parte superior de la foto. | |||
==== Create the shapefiles using land cover data ==== | ==== Create the shapefiles using land cover data ==== | ||
Land cover data can be either vector like CORINE or raster like NOAA. However if the files are raster you will have to convert them into vector using a similar way described below. European CORINE scenery and most large-scale custom United States scenery such as Hawai'i or the Pacific Northwest were created using available third-party land cover data. | Land cover data can be either vector like CORINE or raster like NOAA.

==== Crear los archivos de forma a partir de datos de cobertura del suelo ==== | |||
Los datos de cobertura del suelo puede ser vector o raster como CORINE como NOAA. Sin embargo, si los archivos son de trama, tendrá que convertir en un vector con una forma similar se describe a continuación. Europea CORINE paisaje y la mayoría de gran escala a medida paisaje Estados Unidos, como Hawai o el noroeste del Pacífico se han creado utilizando disposición de terceros los datos de cobertura de la tierra. | |||

There is Switzerland land cover data available for both Bodensee and for most of Switzerland which has been created using land cover classification techniques. In this scenery, the developer takes a satellite photo and, using raster manipulation software such as GRASS, manually classifies each pixel in the satellite as a land cover type. After refining the data, the data is turned into a vector format and cleaned again, removing oddities such as cloud cover. This is probably the most difficult type of scenery to create, but can cover a large area most efficiently. | There is Switzerland land cover data available for both Bodensee and for most of Switzerland which has been created using land cover classification techniques.

==== Crear los datos de cobertura de la tierra se ==== | |||
No hay datos de Suiza la cobertura del suelo disponible para Bodensee y la mayor parte de Suiza, que ha sido creado utilizando técnicas de clasificación de la cubierta de la tierra. En este escenario, el desarrollador tiene una foto de satélite y, utilizando el software de manipulación de trama, como la hierba, de forma manual clasifica cada pixel en el satélite como un tipo de cobertura terrestre. Después de refinar los datos, los datos se convierte en un formato vectorial y limpiar una vez más, la eliminación de rarezas como la cubierta de nubes. Este es probablemente el tipo más difícil de crear un paisaje, sino que puede abarcar una gran área más eficiente. | |||
A mix of the last two approaches is usually the most beneficial unless you are using an end-product such as CORINE. For instance, in the new Pacific Northwest sceneries, there are some oddities where rivers start falling under 30m wide. These need to be fixed by hand and then merged which can be a time-consuming process. | A mix of the last two approaches is usually the most beneficial unless you are using an end-product such as CORINE.

Una mezcla de los dos últimos enfoques suele ser la más beneficiosa a menos que usted está usando un producto final, como CORINE. Por ejemplo, en los nuevos escenarios del Noroeste del Pacífico, hay algunas rarezas donde los ríos comienzan a caer bajo 30 metros de ancho. Estos deben ser corregidos a mano y luego se fusionó que puede ser un proceso que consume tiempo. | |||
