ID(Identification File)
GISBox is a one-stop 3D GIS data editing, conversion and publishing platform that supports editing in multiple GIS formats such as OSGB/GEOTIFF/RVT, converting to 3DTiles/Terrain and publishing.
Introduction
In GIS (Geographic Information System), ID files usually refer to identification files, which are files used to identify data sets. They usually contain metadata information such as the name, version, author, format, creation date, scope, and summary of the data set to help users understand and manage the data set. The format of the ID file can be a text file, XML file, or other structured format. In GIS, the metadata information of the data is very important, which can help users better understand the data set, evaluate data quality, and select appropriate data and analysis methods. Therefore, the ID file is also very important.
File Format
ID files can be in a variety of formats, including but not limited to:
Text files: stored in plain text, easy to read and edit.
XML files: structured storage using Extensible Markup Language (XML) to facilitate data exchange and sharing.
Other structured formats: such as JSON, CSV, etc., select the appropriate format according to specific needs.
Pros
1. Data integration and matching: ID files can be used as a data integration tool to integrate data from different sources and formats but with the same or highly overlapping spatial locations.
2. Accelerate data query: ID files can accelerate the data query process because they can quickly access the index of data without scanning the entire data set.
3. Support spatial data visualization and analysis: ID files can be used for spatial data visualization, such as map services, to help users intuitively view and understand data.
4. Facilitate data management: ID files can more easily manage and maintain data sets by indexing data, including operations such as data update, deletion, and addition.
Cons
1. Large storage space requirements: ID files need to store a large amount of spatial coordinate data, so the file size is usually large and requires more storage space.
2. Read, write and query performance: Since ID files contain a large amount of spatial data, it takes more time and computing resources to read, write and query the file.
3. Format complexity and compatibility: The ID file format is a complex data format that requires specialized software and technology to process and parse.
Application Scenario
In GIS, ID file refers to identity file or identification file, which is used to match each feature in a set of vector data with features in other vector data. When it is necessary to integrate data from different sources and formats but with the same spatial location or high overlap, ID files can be used as a data integration tool to match features in different data sets through spatial location and achieve integration.
Example
- The datasets are integrated through ID files.
- Computes the geometric intersection of the input features and the identity features. Input features or parts of them that overlap with the identity features acquire the properties of those identity features.
File Opening Mode
- Open the ID file with Adobe InDesign:
