MojXML Tools

A collection of tools for processing and analyzing MOJ XML data archives, commonly used for Japanese cadastral information.

Features

• Coordinate System Statistics: Scans directories containing MOJ ZIP archives (including nested ZIPs) and counts the occurrences of "任意座標系" and "公共座標系" specified within the XML files. It utilizes the -search-list.csv file within the main ZIP archive to determine which nested ZIPs contain relevant parcel data.

Prerequisites

• Rust programming language and Cargo package manager. (Install Rust)

Input Data Format

The tool expects a directory containing one or more ZIP archives. Each main ZIP archive should contain:

1. A CSV file named ...-search-list.csv (encoded in Shift-JIS). This file lists the nested ZIP files and is used to count parcels associated with each nested archive.
2. Nested ZIP archives (e.g., 13101-0000-0000.zip) referenced in the search list CSV.
3. These nested ZIP archives contain the actual MOJ XML files (.xml). The tool reads the <座標系> tag within these XML files to determine the coordinate system type.

Note: You can download the required MOJ ZIP archives using tools like amx-project/dl-tool.

Building

Navigate to the project directory in your terminal and run:

cargo build --release

This will create an executable file in the target/release/ directory.

Usage

To run the coordinate statistics tool, execute the compiled binary, providing the path to the directory containing your MOJ ZIP archives:

./target/release/mojxml-tools coordinate-stats --path <path_to_your_zip_directory>

Replace <path_to_your_zip_directory> with the actual path to your data.

The tool will scan the directory, process each ZIP file in parallel (showing a progress bar), and output the total counts for each coordinate system type found.

Example Output:

Scanning directory for zip files: "path/to/your/zip/directory"
Found 15 zip files. Starting parallel processing...
[00:00:05] [########################################] 15/15 (00:00:00)
Finished processing all zip files.
