In China, Sky Map was a relatively clear free satellite map. It was an online map of the national geographical information public service platform. It supported three modes: flat map, image (satellite map), and terrain. The resolution of the satellite map was very high, and many rural images were very clear. However, it was not updated in a timely manner, and the support for foreign regions was not good. Only rough images could be seen. Tuxin Earth (search for "Tuxin Earth" on the desktop and search for "LMV" on the mobile app market) was also a good free satellite map software. It could browse a variety of map sources such as sky maps and images, as well as high-definition satellite offline images that could be downloaded and used. It was currently the only software that could do map analysis after Google Maps and Ovi's. In addition, Baidu's satellite maps were also free to use. The image performance in big cities was still acceptable. Baidu's Street View maps supported more cities and were updated relatively timely. However, Baidu's satellite maps were not updated in time and had poor clarity (especially in rural areas).
Weather satellite cloud pictures were pictures of clouds taken on the weather satellite and sent to the ground receiving station. The cloud picture had meridians and latitudes. Through the analysis of the weather satellite cloud picture, it could provide the various weather systems and their movements and developments over the sky. It could also deduce the distribution of high-altitude winds from the continuous shooting of the cloud picture, which was one of the important references for the current weather forecast. Cloud maps could be divided into two categories: 1. The visible light cloud picture was a satellite cloud picture that was sensed by the scanning radiometer on the weather satellite (the television camera was used in the early days) and sent to the ground station. The brightness of the picture reflected the strength of the cloud's reflection. It was widely used in the study of the movement and development of clouds and cloud systems, and in the monitoring of the occurrence, development, and movement of typhoons and other weather systems. However, because cloud pictures were taken in the visible light band, their brightness and color depended on the nature of the clouds and the sun's altitude angle. At the same time, they could not be taken at night, so they were limited. 2. The infrared cloud image was a cloud image that the scanning radiometer on the weather satellite used the infrared radiation channel to sense and send to the ground station. Its brightness roughly reflected the temperature at the top of the cloud, so it also reflected the height of the cloud top. Generally, the lower the temperature and the higher the height of the clouds, the whiter the color on the map, and vice versa. Because infrared remote sensing could sense and send cloud images to the ground station day and night, and could analyze the temperature of high clouds and cloud tops, it provided a lot of information that visible cloud images could not provide. However, the resolution of infrared cloud images was lower than that of visible cloud images. In practical applications, the two were usually used together, complementing each other and gaining a wide range of applications. At the same time, the visible and infrared cloud images also provided a large amount of ground information in cloudless areas. For example, the visible cloud image could reflect the surface of the ground, rocks, forests, crops, pastures, lakes and other different cover of the surface, while the infrared cloud image could reflect the thermal temperature of the surface and the ocean surface. Cloud images were also widely used in crop yield forecast, forest fire monitoring, marine fishing area determination and other social and economic activities. In China, one could get the latest real-time satellite cloud images of the Central Weather Station through Tianqi.Tianqijun.com. From there, one could get the latest information about typhoons, rainstorms, cold waves, fog, and other weather forecast.
Here are some ways to get high-definition satellite maps for free: - Tianditu: An official geographical information platform with rich functions. It provides high-definition satellite images and supports custom cartography. - Standard Map Service System (Http://bzdt. ch. mnr. gov. chn/): It provides a variety of choices such as China maps, world maps, and special maps. It supports JPG and EPS format, and can be viewed and downloaded for free. In addition, there were also some software, such as the free version of the high-definition satellite map, which could view high-definition images from all corners of the earth, but this required the user to download the software themselves.
Tuxin Earth PC (LMV) was a software that allowed free download of high-definition satellite images in China. It integrated with the Google series of maps.(such as Google Satellite, Google Images, Google Maps, Google Terrain, etc.), Baidu Images, Gaode Images, Sky Map Images, Google Images, Resource 3 Images, ArcGis Images, Wdmi Images, and many other satellite image maps. It can also load more than 300 kinds of high-precision topographic maps, various road labels, navigation maps, etc. All the map sources can be downloaded for free offline use. In addition, the Symbiosis Earth APP was a free satellite map software developed by Changguang Satellite Technology Co., Ltd. It provided satellite images based on the self-developed optical remote sensing satellite constellation "JiLin No. 1". However, at present, its independent map source only supported China's regional satellite images. Other than supporting the sky map, it did not support other map sources. The Star Map Earth APP was also free. It was released by Zhongke Star Map Hefei Digital Earth Co., Ltd., using their own Zhongke Star Map source.
There were some free 3D satellite maps in high definition. For example, there was a free 3D satellite map software. It was a good map software that provided one-stop navigation services. It could inquire about public transport, subway, and other information. It could input information about the starting and ending points to obtain travel routes. It supported satellite maps, mobile navigation, satellite cloud maps, and other services. It could also inquire about current road conditions. There were also some 3D map apps that included a variety of 3D maps for download. They had high-definition images and a variety of functions. For example, they could carry out 720-degree VR immersive tour to explain scenic spots, provide hand-drawn intelligent guides for global scenic spots, and provide full coverage of street views at home and abroad.
Google Satellite Map had a high definition and was updated in a relatively timely manner. It was one of the more useful satellite maps. Sky Map was operated by the national geographical information public service platform, and the satellite map had a high definition rate. The Ovi Map could switch the map source and included the Google Satellite Map source. The Earth APP was faster and clearer than the Ovi Map. The Symbiosis Earth APP had a powerful remote sensing image capability. However, it was difficult to directly determine which satellite map was the clearest. It might depend on different regions, equipment, and personal standards of clarity.
The following is some information about the satellite map: The Changguang Satellite released the world's first high-definition global map taken by the "JiLin-1". It selected 1.2 million views from the 6.9 million satellite images, covering all land areas except Antarctica and Greenland. The resolution exceeded 90% to reach 0.5 meters. China had a new version of the national satellite image map. This was the first publicly released 0.5m resolution national satellite image map. It was shot by 108 satellites covering the whole country 65 times. Finally, 1.5% of the high-quality image slices were selected and released. The image coverage was as high as 99%, including 34 provincial administrative regions in China, China Taiwan, Hong Kong, and Macau, and some islands in the South China Sea.

The G version could only be accessed through the Internet. For related information, please refer to the detailed explanation in the article "How to View Official Synchronization Images". There was also the source code of the land use classification map. The land use classification map had a separate classification, which was a special map of the industry. If you needed more similar special maps, you could download them from the micromap PC. You could also download other types of map data such as satellite images or elevation from the micromap PC. The downloaded data could be projected and converted to meet the application needs of different projects.
Satellite Reality Map was a software that could view panoramic street views and satellite navigation. It could view street views and maps by zooming in and sliding on the map. It supported GPS automatic positioning and road condition display, allowing users to truly experience the street view of their hometown. They could also experience the domestic and foreign street views in VR panoramic mode and explore the world's scenic spots without leaving home.
Although there were many applications called Beidou Maps, some of them could be misleading. For example, the relevant applications on the iPhone might not be related to the Beidou global navigation system because the iPhone did not have the Beidou chip. In the Android system, if the phone had a built-in Beidou chip (more than 95% of the Android-based phones sold in the past three years had built-in Beidou satellite navigation chips), then when using common navigation software such as Baidu Maps and Gaode Maps, they might be able to enjoy Beidou satellite navigation services. There was no need to download an application called Beidou Map. If you want to view Beidou satellite related information, Android users can turn on the location service authorization and upgrade the latest version of Gaode, go to an open location outdoors, and follow specific steps to check the number of Beidou satellites that are serving them. However, iPhone users cannot fully view the real-time Beidou satellite details due to the phone system. At present, there was no specific information on the features and usage of Beidou Map HD Satellite Map Free Version. It was impossible to answer its specific functions and conditions.
A 3D satellite map was a map that used satellite technology to obtain information about the Earth's surface and presented it in three dimensions. It could provide satellite images of multiple cities, such as New York, London, Tokyo, and many other places around the world. The scale could range from 2 kilometers to 10 kilometers. These maps could be used for geography studies and also allowed people to see different scenes around the world, such as the roofs, courtyards, and cars at the entrance of their homes from space, the 3D view of the Sydney Opera House, the streets of Japan, and the surrounding vehicles and greenery. Some mobile satellite positioning systems could also switch to satellite VR mode to view real objects, such as houses, trees, people in the yard, etc. When making 3D satellite maps, a variety of map resources would be used, such as Google, arcsis, MicrosoftImage, Baidu Map, Tengxun Map, Gaode Map, Sky Map, etc. Different maps had their own advantages and disadvantages in terms of image clarity and color rendering. For example, from the perspective of the clarity of domestic satellite images, Sky Map was comparable to Google's satellite images. In some areas, Sky Map was clearer, and from a global perspective, Google Map was the clearest. Furthermore, in terms of color rendering, the Google image looked more realistic and natural, while the sky map image was darker, like an unprocessed original.
Beidou Satellite Map Free Version 2024 was a very useful software for users who needed precise navigation.
