This Common Spatial Data Infrastructure (CSDI) consists of a collection of geographic datasets, including maps, satellite imagery, and other geospatial information that are used to support various GIS projects. The datasets have good data quality, it is reliable, free to access, support different file format. GIS professionals can determine the suitability and potential usefulness of CSDI datasets for supporting future GIS projects. It helps in making informed decisions about their integration and application in GIS analyses and spatial planning.

In the map I created, I added some parks, and some places related to the natural environment and ecological environment, observed their spatial distribution.

The green points are Country Parks, that’s why You can see that they are distributed in areas covered by green vegetation, and the overall distribution seems to be uniform, covering diverse landscapes such as mountains, forests, coastline, and reservoirs. They could offer some activities like hiking, while also serving as important conservation areas for biodiversity and natural ecosystems.

The blue points are the Location of Marine Parks and Marine Reserve, so that they are along the coastline and islands. From the map it shows that they are located in different parts of Hong Kong, including the New Territories, Outlying Islands, and Sai Kung. The Marine Parks and Reserves offer various marine habitats, such as coral communities, rocky shores, and diverse marine life. The spatial distribution of these areas aims to protect and conserve the marine environment while providing opportunities for sustainable marine recreation and education.

There are 127 orange points which represent Parks, Zoos and Gardens, you can see they are distributed in residential area. It can guess that these places in the urban areas, there are smaller neighborhood parks and playgrounds that provide green spaces for residents to enjoy.

Last but not the least, the yellow lines are several ecologically important streams that play a vital role in supporting the region's biodiversity and natural ecosystems. The streams mainly gather in the northeast and southwest. Many of these streams are located in areas with high ecological value, including country parks, nature reserves, and areas of high biodiversity. Some of the ecologically important streams are found in the New Territories, these streams may important for maintaining water quality, supporting aquatic life, and providing habitats for various species of flora and fauna. Additionally, several streams are located in the rural and less developed areas of Hong Kong, perhaps they are providing a natural environment that is crucial for the conservation of aquatic species and the overall health of the ecosystem.

By looking at the distribution of these places, we can see the Hong Kong government's efforts to balance urban development and nature conservation. The highly urbanized Hong Kong has a good surrounding ecological environment, so that citizens can have a relax in those urban parks, country parks and marine parks in their leisure time.
