Public-Version 1:1,000,000 Basic Geographic Information Data Guide
The national public-version 11,000,000 scale. The overall currency of the dataset is 2019. The data uses the China Geodetic Coordinate System 2000, the 1985 National Height Datum, and geographic coordinates.
The national public-version 1:1,000,000 basic geographic information data (2021) covers China's land area and major islands, including Taiwan Island, Hainan Island, Diaoyu Dao, the South China Sea islands, and their adjacent waters. It contains 77 map sheets at 1:1,000,000 scale. The overall currency of the dataset is 2019. The data uses the China Geodetic Coordinate System 2000, the 1985 National Height Datum, and geographic coordinates.
To meet public demand for geographic information data resources, the National Geographic Information Resource Catalog Service System, authorized by the Ministry of Natural Resources, provides free downloads of all national 1:1,000,000 public-version feature layers. The downloaded data is distributed by standard 1:1,000,000 map sheets. It includes nine datasets: hydrography, settlements and facilities, transportation, pipelines, boundaries and administrative divisions, landform and soil, vegetation, place names, and annotations. Spatial relationships between features and related attribute information are preserved.

The downloadable files are vector data, not final maps. Their visual appearance may differ from a symbolized final map. When using this data to compile maps, users must strictly follow the relevant provisions of the Regulations on Map Management. If the compiled map will be released to the public, the user must also complete the map review process according to law.
Data Introduction
Result Data Organization
The national public-version 1:1,000,000 vector data (2021) includes nine datasets: hydrography, settlements and facilities, transportation, pipelines, boundaries and administrative divisions, landform and soil, vegetation, place names, and annotations.
Layer names use four characters. The first character represents the data category, the second and third characters are abbreviations of the data content, and the fourth character represents the geometry type.
Map Sheets
The subdivision and numbering of national basic-scale topographic maps are fixed. They are described in detail in the standard Subdivision and Numbering for National Basic Scale Topographic Maps (GB/T 13989-2012).

For 1:1,000,000 scale, the map-sheet subdivision is as follows:

Download Data
Use the locating tool to search by administrative area, road name, hydrographic feature name, place name, or map sheet.
For example, search by administrative area and locate Hebei Province.
Click the successful query result on the right. Four standard map sheets will appear. The table lists the sheet number, production time, geodetic datum, and data format. Add all of them to the result cart.
Then go to the result cart and click checkout.
On the review page, a special-service selection appears at the bottom. You can ignore it and submit the order directly.
After submitting the order, a data download button appears on the order page. When downloading data, you need to fill in information on two pages. Be sure to complete the information accurately rather than entering arbitrary values.
Use Data
Data Overview
The downloaded data is stored in GDB format, a proprietary ArcGIS format. Each file is a ZIP archive named after the map-sheet number.
Here is an example: download the sample.
You can inspect the archive contents with decompression software, but because it is a database file, it cannot be opened directly like a regular document.
Data Upload
Upload the data in ZIP format. iXGIS can directly recognize this data format and convert it to pgv format.
Data Loading
Load the data.
After loading, the dataset is available in the current project.
Layer Content
The mapping between layer names and features is as follows:
- Naming rule: layer names use four characters. The first character corresponds to the feature category, such as C, H, or R. The second and third characters are content abbreviations, such as PT for survey control and HY for hydrography. The fourth character corresponds to the geometry type: P for point, L for line, and A for polygon.
- Feature categories: covers nine major categories based on the original description: positioning foundation (C), hydrography (H), settlements and facilities (R), transportation (L), pipelines (P), boundaries and administrative divisions (B), landform and soil (T), vegetation (V), and place names and annotations (A).
