opengis-utils-for-net

opengis-utils-for-net is a skill for Claude Code, Codex from znlgis/opengis-skills. It costs 47 tokens per session (4,038 once invoked), scanned A, original, MIT.

A set of GIS utilities for .NET and C#, covering spatial data files, shapes, coordinate systems, and validation. GIS means software for storing, analysing, and displaying location-based data.

In plain words
What is it for?
Use it in .NET applications to read and write formats such as Shapefile and GeoJSON, transform coordinate systems, perform shape calculations, and check spatial data.
Why use it?
It avoids writing separate code for common map-data formats, coordinate conversions, and geometry operations.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

opengis-utils-for-net scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

概述

OGU4N (OpenGIS Utils for .NET) 是一个面向 .NET 的 GIS 实用工具集,提供矢量数据读写、几何运算、坐标系管理等能力。核心特性:

  • 统一数据读写OguLayerUtil 一站式读取/写出 Shapefile、GeoJSON、FileGDB、GeoPackage、KML、DXF、PostGIS、TXT 等格式
  • 几何运算GeometryUtil 提供 50+ 静态方法(空间关系、集合运算、属性查询、拓扑验证)
  • 坐标系管理CrsUtil 支持 CGCS2000 系列坐标系变换与分区计算
  • 辅助工具:编码检测、文件压缩、自然排序、数字格式化等
  • 仅 GDAL 引擎:.NET 版本基于 GDAL/OGR 实现(与 Java 版本不同,后者同时支持 GeoTools 和 GDAL)

环境要求: .NET Standard 2.0+(兼容 .NET Core 2.0+、.NET 5+、.NET Framework 4.6.1+)

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
