Convert SCM to ASC

Understanding scm and asc file formats

SCM files are commonly associated with StarCraft Map files, used by the popular real-time strategy game StarCraft. These files contain map data, including terrain, units, and triggers, and are typically used for gameplay and map editing within the game environment.

ASC files, on the other hand, are ASCII text files that can represent a variety of data, but in the context of mapping and gaming, they often refer to ASCII grid files used in GIS (Geographic Information Systems) to store raster data in a plain text format.

Why convert scm to asc?

Converting an SCM file to an ASC file is typically done to extract map terrain data from a StarCraft map for use in GIS applications or for analysis in other software that supports ASCII grid formats. This process is useful for modders, researchers, or developers who want to analyze or repurpose StarCraft map data.

How to convert scm to asc

There is no direct, one-click converter for SCM to ASC due to the proprietary nature of StarCraft map files. However, the process can be accomplished in a few steps:

1. Extract terrain data from the SCM file using a map editor such as SCMDraft 2 or StarEdit.
2. Export the terrain or heightmap as an image or data file if the editor supports it.
3. Use a GIS tool like QGIS or GDAL to convert the exported data (e.g., image or CSV) into the ASC (ASCII grid) format.

Recommended software for scm to asc conversion

• SCMDraft 2: A powerful StarCraft map editor that allows you to view and export map data. Download from stormcoast-fortress.net.
• QGIS: An open-source GIS application that can import images or CSV files and export them as ASC files. Download from qgis.org.
• GDAL: A command-line tool for raster and vector data conversion. Use gdal_translate to convert supported formats to ASC.

Step-by-step conversion process

1. Open your SCM file in SCMDraft 2.
2. Export the terrain or heightmap as an image (e.g., PNG) or CSV file using the editor's export function (File → Export).
3. Open the exported file in QGIS or use GDAL to convert it to ASC format:
   • In QGIS: Layer → Add Layer → Add Raster Layer, then Raster → Conversion → Translate (Convert format) and select ASCII Grid as the output format.
   • In GDAL: Use the command gdal_translate -of AAIGrid input.png output.asc (replace input.png with your exported file).

Conclusion

While there is no direct SCM to ASC converter, using SCMDraft 2 to export map data and QGIS or GDAL to convert it to ASC format is the most effective workflow. This allows you to repurpose StarCraft map data for GIS or analytical applications.
