Function introduction

---

Global satellite image download

​​ ​Different from many Google Map-based download tools on the market, this software directly downloads data from Google through a complete interpretation of the Google Earth data transfer protocol. Earth server downloads data, and the downloaded images do not have Google watermarks.

Download global historical images

You can download all images from the 1930s to the present, with data dating back to 1930.

Global elevation data download

Supports the downloading of global high-precision elevation data, and downloads the entire elevation data directly from the server. It is different from other software's point-by-point sampling method based on Google Earth. It has high download efficiency and high data accuracy.

No data offset

---

Supports downloading of data of any size and format, and the data has no offset or deformation. There is no need for manual correction or re-registration, which greatly saves labor costs.
Data projection is simple
The data projection is the most commonly used latitude and longitude projection (Geographic Lat/Lon), which is non-web Mercator projection and can be used directly without reprojection.
The date the image was taken is clear
Whether it is Google images or historical images, each image has a clear shooting date, which greatly meets the needs of professional users.

Unlimited downloads, no IP blocking

---

Conventional Google image download tools download a large amount of data, and the IP is easily blocked by Google, resulting in the inability to download. This software perfectly interprets the Google Earth transmission protocol, thereby enabling IP-free blocking and unlimited downloading.
Independent operation, efficient and stable
You can use this software without installing Google Earth. Due to policy restrictions, Google Earth in China often fails to connect to the server. This software does not depend on Google Earth and can still be used normally even if Google Earth is blocked.
