ogrinfo-validator wraps the ogrinfo GDAL tool to retrieve information about provided vector datasets. This package also allows the user to validate their vector data source against set criteria. Validation includes:

• Ability to determine if number of features is beyond specified limit
• If extent of the Vector Dataset is Incorrect

Installation

1. [Install GDAL tools][1] (includes the ogr2ogr command line tool)

2. Install package:

npm install ogrinfo-validator

Usage

ogrinfo takes a file path. The result will include general & validation information.

// Using CommonJS modules

ogrinfov('test.zip').then((result)=>{
    // Do what you need
}).catch((err)=>{
    // Show or handle error
})

// Call with options & Limits
ogrinfov('<file location>', {options: ['summaryOnly','listAll']}, {limits:{ featureCount: 500000, checkExtent: true }}).then((result)=>{
    console.log(result);
}).catch((err)=>{
    console.log(err);
});
