Planetobserver推出新的10M全球图像底座

PlanetObserver has released PlanetSAT Global 2022, a basemap that provides ready-to-perform, cloudless, and homogeneous imagery. With outstanding 10-meter resolution, PlanetSAT Global imagery basemap provides access to detailed geographic information from global scales all the way down to 1:50,000 map scale.

One major feature ofPlanetSAT basemapis the updates that PlatetObserver releases on an annual basis. The company states that outdated imagery is often of little or no use for many projects and solutions – annual updates ensure that users can access the most current image layer available.

For PlanetSAT Global 2022, more than 10 million km² of fresh 10-meter imagery have been ingested in the global basemap. The main updated areas include the United States and the United Arab Emirates. In addition, over 170 major cities worldwide have been updated.

The refreshed imagery content continues to grow. PlanetObserver has committed to an impressive annual update schedule. This makes this global imagery solution more robust every year, having analyzed and processed more than 204.4 trillion pixels of data since 2003.

Cloudless imagery

Selecting the proper satellite imagery to create a mosaic is very challenging. More than 70% of Earth is constantly covered with clouds throughout the year. Consequently, PlanetObserver takes advantage of the different seasons to get the best possible cloudless imagery for each area.

Recently, satellite imagery providers have released “completely cloudless” basemaps. However, this is not achievable for tropical areas in South-East Asia, Africa and South America that are covered by clouds 99% of the time. One common approach is to change the colors of cloudy areas for the map to look homogeneous even though the real geographic data is not accessible. However, this damages the data and gives the user a false overview of the desired area.

Planetobserver的策略是通过选择100％无云源图像来从每个年度更新中从BaseMAP中删除云。然而，对于所有热带地区，它们保持真实像素，即使仍然存在云。该公司的承诺是提供真实可靠的地理信息。

免费查看器

For the first time,PlanetObserver正在集成免费的查看器。以前，只有客户端只能访问底图。今年，该公司已决定使其数据更加可见，并使每个人都有一种旨在的卫星图像应该是如何看待的。
