Okay, I need to create a Wikipedia-style document about "Vector Data" under the categories of Technology > Software > Geographic Information Systems (GIS). Let me start by understanding the requirements.

First, the structure: H1 for the title, an overview section, several sections with H2 and H3 headings, and maybe references or related documents. The content needs to be accurate, objective, detailed enough, easy to read, and use technical terms with explanations. Also, markdown formatting with proper headings, lists, tables, code blocks if needed, and at least 800 characters.

Starting with the title: "벡터 데이터" as given. Then an introduction explaining what vector data is in GIS. Next sections could be on characteristics, applications, formats, challenges, etc. Maybe break down into sections like Definition and Characteristics, Data Structure, Applications, Common Formats, Challenges, and References.

For each section, I need to elaborate. In the definition, explain that vector data represents geographic features as points, lines, polygons. Mention attributes and coordinates. For data structure, talk about nodes, edges, faces. Maybe a table comparing different types of vector data (points, lines, polygons).

Applications: urban planning, environmental monitoring, transportation. Examples like road networks as lines, land use as polygons.

Common formats: Shapefile, GeoJSON, KML. Explain each briefly, maybe a table with format, description, usage.

Challenges: Data accuracy, storage, compatibility between formats. Maybe mention issues like topological errors or data integration problems.

Need to ensure technical terms are explained. For example, "topology" in GIS refers to the spatial relationships between features. Also, use code blocks if there's any sample code, but since it's about vector data, maybe not necessary unless discussing APIs or libraries.

Check for 800 characters. Let me count: each section should be detailed enough. Avoid being too brief. Make sure each H2 has at least a couple of paragraphs and some sub-sections with H3 if needed.

Also, include references to related documents like "지리정보시스템" or "데이터 형식" as per the user's request for a reference section.

Need to make sure the language is professional but accessible. Avoid jargon without explanation. Use examples where possible to clarify concepts.

Now, structure:
